One of the top LT250r builders chiming in here. Please air-leak test that engine. The exhaust valve can be tricky to seal up but once it is, it will jet easily and cleanly.
Again, let me know if you need anything for that machine. I have NLA OEM engine service parts, upgrade parts that I make, and lots of graded used parts.
That FTZ pipe is beyond rare. I've never seen one of theirs that run in the stock pipe routing. The more common(still SUPER rare) FTZ pipe hangs out of the frame on the left side and is HUGE.
If you want that bike to really run well, shoot me a message and I will be able to point you in the right direction. The AAEN porting on your cylinder isn't what most would call great. If you could get a clear pic of the engraving it would help ID if the cylinder was actually ported by them or if someone carved it on there themselves to try to increase the value. Both FTZ and AAEN did port/pipe/carb combos so it is kind of odd to see the mismatched tuner's products on that bike.
I can help with details and history on the parts on the bike and the tuners that made them if you want. Just let me know what you want to know.
Makes me wish I still had my 86.
lol,i thought i was the top lt250r builder???lol.dont pad yourself on the back to hard!!!lol
@@yeahright302 I stay humble. My work speaks for itself. I have rolled back the work load for the last couple years but I still stay in it. You'd be surprised who is who behind the username.
@@rm25088 Do you have an '88 RM250? I'm pretty sure I have a complete top end for one. It would need replate, but is complete.
What exhaust valve?
Glad you stuck with it and decided to take another shot at it. Thanks again for your time today and enjoy the rest of your weekend.
lol,ok thanks!!!
Joe... you've either got super good microphones or THE happiest birds in the whole United States of America!
🤣☺️🐦🇺🇸
That shift drum bolt being gone allowed the drum and the forks to move a lot causing the fork ends to wear thin. Under pressure the gear dogs slip out of contact because the forks allow them to. That worn 2nd gear is too much. Those dog ears have to be more sharp edged .
I thought those forks were a bit shinny. I replaced alot of Sportster shift forks and shims. Looked just like them.
I remember tons of people telling him on the last video. He definitely didn't know what to do.
Hi,really enjoying your channel, you make it look so easy,but I'm sure it's not
Mark
This one has been a tough nut to crack! I admire your enthusiasm and positivity. Thanks Joe, your videos are a gem!💎
I almost spit out my coffee when you said that was a152 jet. Ours had the twist throttle and it was the same year. What a great rig
250 he said.
You were absolutely right, that missing bolt on the shift drum was the initial problem but it was ran that way too long and probably worn the shift forks out of tolerance which you’re probably not gonna see with the naked eye. I don’t blame you a bit, I’d have done the same thing just replacing the bolt and trying it 👍
Oh yeah!!!
We’re off…..great Sunday morning content!
I just saw this in my YT feed and I’m glad you decided to be persistent with this machine, she deserves the repair!
Joe doing what Joe does best GETTING DOWN TO THE PROBLEM AND FIXING THE TASK AT HAND. GREAT JOB!!! Always a pleasure to watch.
Relax.
Shi😂
Joe, i gotta say i admire your patience when you get into some crappy situations now and then, a lot of times this younger gen are very short tempered, but you maintain your cool quite well my friend...GOOD ON YA!👍👍👍👍👍
Brilliant video Joe watching from Edinburgh Scotland UK 🇬🇧 👍
Also a Scottish viewer Glasgow 😅
I have ancestors from Scotland!
Do you guys ride quads in there? 🤔
@@manaaalsuwaidi3643 I do quads and bikes 👍
I had one of these as a kid. Never did I get a chance to ride it because it was sold to pay the bills. Boy, would I love to get my hands on another. These quads were massive
Video taping the ride out at the land and it sure brought back some great memories. I did a little Motocross myself when I was younger and I had forgotten the thrill of Shifting through the gears and hearing that two-stroke scream
What a sweet feeling when it's fixed. I'm glad you recycled used parts.
Gotta love holding it flat in the dirt!
Good work Joe.
This quad brings back some memories. I didn’t own it but my friend who lived up the street did, I think 86/87, I had an 82 ATC250r with a little motor work and higher compression, we used to go ride in the hills all the time in summer then ride back to his place to go swimming.. great times back then, I think mid early 90s… don’t grow up people!!! Enjoy those easy days, my only advice, get a nice silencer for it, those bikes love a good pipe and silencer, really brings out the animal
You really know what you are doing with these bikes and 4 wheelers. I love watching you work on them.
A great work ethic is great to see!
I've been watching your videos all last week. You have a talent, many thanks for your work on this channel.
Bro is literally teaching you how to rebuild a motor. I been watching these videos for years and I’m still going faithfully. You need to start your own shop or something fr
He never taught me a damn thing except how to get pissed off at watching someone screw s*** up some of us in here have done this many more years than any of you had added together
Happy Days Joe Has Posted 🔥🔥🔥
I knew you'd get it running right, you sure know your stuff! Love your videos!
You should do another collection video and show your favorite stuff
One these race bikes/quads. -Always nice to have a 2nd or 3rd engine/bottom just sitting and waiting to go in. =Race 1 and work on the other.
That's what I used to do. I had a practice bike and a race bike. The race bike was strictly for that purpose alone, while the practice bike took some serious abuse. Every Sunday was fun for two reasons. # 1 was the racing, and # 2 was because I got to ride what was essentially a brand new bike.
Joe. So glad the new tranny parts fixed this. Nice Quad!
One thing I wanted to mention. I see/hear you miss 2nd gear often when test riding your vehicles. Don’t be afraid to click upwards when you’re going into 2nd. Give it all you got with your ankle and pull up.
😊
My my my what a mess. But great content as always. Hey Joe would love to see a Suzuki LT 80 on the channel that’s one that’s been around for a while and I don’t think you ever had one on here
that 1-2 shift is what rounded the dogs & causes the trans to 'pop' out of 2nd.
1st doesn't fail because it is pre-selected & doesn't get the operator's 'shock load' via the clutch.
I had a YZ465 once and when it had rounding on the gears like that it would slip out of gear every time power was applied.
Nothing like the feeling of finally fixing something that was hard to figure out
Glad you found the issue, it`s hard to believe that little bit of wear caused the problem, but obviously you still had something rubbing which explains the shavings still in the oil, there was something wearing on those gears and shift arms, well done.
The sweet taste of victory.
Well done here Joe.
Being out there by yourself and with no one around, I guess you just took my comment from a previous video, about you running the piss out of a 4-wheeler that, you could end up with a broken neck or back if a Tie Rod let loose And you in a wheelchair, And someone else serving your other half, Your lucky the tie went flat and a tie rod didn't let loose, No I'M NOT PICKING ON YOU I ENJOY YOUR CONTENT
How about wearing some moto boots at least? Maybe some knee pads? I cringe every time I see him riding in running shoes.
@@eddyedwards Only someone as stupid as he's being would agree with that, to lose your life or wife just to go fast
@@eddyedwards True, but that doesn't mean those who know better shouldn't try to warn him. Accidents do eventually happen on motorbikes. And if you're
riding bikes every week, especially old junky untested ones, the chances just get higher. The repercussions can be life changing simply catching your foot on a rock wearing tennis shoes going 50 mph.
Very interesting to watch. I am really pleased you succeeded.
BRAVO, your knowledge and patience paid off long after I'd taken a sledgehammer to it. Nice little quad, for sale or for Joe's World of Wheels museum
Great work really enjoyed the Process!! Thanks for bringing us along!! UK
Man I’m constantly astonished at your tenacity with these beasts. It’s so inspiring👍
Great Job, it is always the fine/little things that trip me in repairs. Sounds great.
2Vintage slaughters the at home rebuild game. Love this channel. I own a 2001 kx250. Which I haven't seen Joe work on yet. But, I'm sure eventually he'll get a deal on one and it will make a great video.
Nothing like fixing something twice God bless from Newcastle Australia 🇦🇺
Hey Joe, place a slim O ring on the shaft with the litttle gear that likes to go AWOL. That way, you can slide the parts together and the O ring will not cause difficulty. I do that when I build transfer cases and transmissions because if the needle bearings get away from me, it all has to come apart and be reloaded.
In my experience one popping out of gear is bent or worn shift forks. I know you measured them and the thickness was the same. But I’d bet the forks that came out were slightly bent from the shift drum moving around.
Sheesh full tear down again,gl brother!😬😬👀👀😬🤔🤝
Fantastic work!
Love rebuilding 2 bangers take tank off u got so much room to work 4 strokes god dam most then suckers are jammed in there to the point of no room
Great job, at time frame 33:59 you can see where the gears have rubbed the case next to the big bearing in the r/h case ,most probably when the end bolt was missing previously .Is that where thee metal shaving came from.
Could very well be. Besides regular clutch wear which can be seen with every oil change (it makes the oil look like metallic paint) anything large enough to be able to feel with your fingers is abnormal wear.
@@stkyfngrszmooth The clutch is on the outer case ,and not were i described .
@@johngriffith5231 Yes, but it still shares the oil with the transmission.
@@johngriffith5231 Yes, but the clutch still shares the oil with the transmission.
I follow your job from some time now.
it is very interesting and it incress my knowledge a lot.
on this case, what it would be very nice, it is, on the old gear, to understand what was the issue.
continue like that, it is the TOP
It was definitely those rounded over shift dogs. It doesn't take a lot of wear for those to start slipping out of gear.
I have the same year lt250r and if I’m not mistaken they is another dot on the crank to line up with the counterbalance gear and the gear for the crank to make sure everything is aligned correctly , thank you for this detailed video of the lt250r motor can’t wait until the race between the Tecate lol 😂
It's better to be the hammer than the nail. Nice work Joe.
you got it sorted mate well done
Another good fix, but don't forget to feature the dog.
Great job!!!
..she sounds really tight and.fresh, sounds like u can drop the main a few to get it revving higher at full throttle and richen the pilot or maybe turn the air screw half a turn richer , Since u can literally rebuild.any motor now , next genre to start mastering is Suspension,...rebuilding, serving, oil, seals, disassembly, special tools tht motion pro should send u free as long as u advertise.using it in videos....surprised u don't leverage even more of.your massive following to aquire free tools from like minded companies.into moto....
I knew you’d get it fixed, great job!
I own a 86 lt 250 and from my research thes are known to be excellent trail bikes.never really meant to wind up like hondas trx250 r. Take that thing to the mountains and run some trails with a group and you will love it!!!!
Another great video. Thanks for posting.
My cbr600rr would slip out of 2nd gear on acceleration, I found the dogs and recesses on 2nd gear to be worn exactly like yours except the shift fork that engages 2nd was deeply gouged, not bent but gouged, and those 3 things added up to 2nd gear not staying engaged. It's been 10k miles since I fixed it and 2nd gear is still going strong. Good job Joe transmissions can be very tricky
I had that exact model as a kid! I’d love to own another!!
If you're still sick of looking at it I'll buy it from you. I live on the other side of the big lake from you.
Awesome job! Never give up bro.
Great work joe.
Philips screw head that has the bearing hold-down has obvious wear on camera.. Zinc plating or just Zinc would be shiny metallic
57:40 I'm always waiting for a deer to run out in front of him. Terrible, yes, I know, but I've seen it too many times.
You're missing a motor mount between the head and the frame. Love the videos!
FTZ - full race, high end. -See if you have the FTZ head mods. Pipe is worth some money. Could swap to cheaper DG (new/used) for thicker pipe and better off road torque.
I had the full DG setup on my 1985 QuadRacer, but it didn't matter because my brother could still smoke me on his bone-stock 1985 ATC250R. Those things were stupid fast.
I knew you would get it!
Nice job!
That was great. Just goes to show how finnicky gearboxes can be. A friend had a 125CC can't remember what it was but on re-assembly the gears would go from 1 to 3 to 2 ! He stripped and put it together several times but couldn't find out why. He may have done it in the end, not sure. The apple trees look reasonable, can we get a progress report on the farm ? You never mentioned potatoes again so may have changed your mind on that one. All good though, most enjoyable, you have great skill. Lovely to watch, thanks :)
Good job! Now time to enjoy it.
Sounds like the power valve isn't opening up when at high rpm! Basically sounds and looks like there is no power band
I was gonna say same thing! No change in tone as rpm increase.. its almost like a vtec when that powerband kicks on my machine anyway.. and that’s the 87 with bigger air intake port.. thing should sound a bit better.. Joe knows it too tho. Maybe the powervalve needs adjustment 🤷♂️ anyway that shouldn’t be too terrible to figure out
@@fromex2lsturbo I have the same quad and when my power band kicks in I can barley hold on to the handle bars
@@jessiej3991 your shit is dialed then 🤙
that pierce that was in the crankcase of the last video looks a lot like the ears on these transmission gears. hope that won't be a problem on that quad in the future.
Great project, good looking quad, argh more work
Replace that packing in that silencer it will sound so much better
Great to watch , thanks so much.
Another great job.
2nd gear shifting dogs are rounded off on the ends and thats what makes them push away frome each other. if you had dove cut the dogs with a die grinder tool you would have never had to go into it twice Dove Cutting pulls the gears into each other ive done dozens of transmissions with that proceedure
This thing is awesome man. I'd love to have this quad
brilliant well done sir very enjoyable ❤
That claw hammer gets me every time, get you a wilton b.a.s.h hammer set they'll last you a lifetime
that awesome its fixed good job Joe
popping out of gear is a worn shift fork! I had a 93 zx7 ninja that started doing the so i'd just go from 1st to 3rd
I’ve never seen you mess with the air screw on any carb, you’d be surprised what it does
Love watching, dying to find out, what you missed and what you find....
Great work, another one fixed up.
LOVE YOUR VIDEOS VERY HELPFUL THANK YOU
Very cool and very safe especially on inclines! $4,000 + tax= $4330.00
It’s a good looking machine yet and kinda rare, I still don’t think you’ll have any trouble making some money on it 👍
Ever heard of backgrinding?? Look it up. A little bit of grinding on the gear dogs in the right place and when the load comes on they engage and some. The old gearset would have worked. Pays to check end float too.
I still think the lockout bar for the barrel had play in the faulty gearbox from the last video assembly. Like a bush was missing or the rod had worn
Would love to see you polish and port a 2 stroke 250 in one of your videos. Have always been curious how to do that properly. Love your videos, have seen them all. Thanks
So, I was wrong on my prediction of rounded off dogs, it was over all wear. Wasn't this the motor you found a piece of cog in the clutch side? I didn't see anything missing.
Remember that bolt and washer missing on the shit drum. That proably did not play well with the shift forks and drums leading to wear and bending that then made sloppy engagement of the gears and caused the wear on the gears when you rebuilt it. I would bet it's the shift forks that need to be replaced. The gears are probably fine they are just not getting good engagement because of the shift forks.
Great video! Is it me, or did Suzuki use the same frame for the 230 and the 250?
No, two completely different animals.
@@stkyfngrszmooth Just looked similar to me.
@@cobblersgarage256 No worries.
Another great video Joe if it hadn't worked I think we would have seen you scream 😀 😜 😉
Pretty nice machine 👍🏻
What are your future plans with this quad? I know someone who maybe interested. Also a great build series on this machine.
Great Job 😊
Awesome project .
I got the brightness turned down on my iPad and I can definitely see those flakes
Nice job!!👍
"It pays to grease the gasket", that's what she said hahaha!

Love your mechanic skills but man. Moto seal or ultra gray on the cases. I’ve never seen a factory engine use black! I’ve rebuilt a lot of engines and everytime black was used there was a leak!
After watching the first video I was wondering if it was the shift forks.
