@@fixit6431 your very welcome!

Has a wiseco forged piston, Hpd trail pipe, shaved head, and a Keihin PWK 39mm quadvent carburetor.

@timothyzeimet4972 hows the pipe and carb been for you? I'm about to put a AAEN Top end pipe on my scrambler 400 with a 38 tmx flatside. Gonna see how those help the stock 400.

The pipe moves the power band a little higher in the rpms and ramps the torque up. Change the clutching springs to grab right when the pipe kicks in. The Keihin absolutely runs the engine beautifully. Very fast fuel transition, and no hickups right into wide open throttle. The biggest hurdle mounting the carb is finding the head side mount to fit the big mouth of the carb.

​@timothyzeimet4972 ah okay. That sounds like a great setup. Yeah I could see how the bigger carb could have that problem. Good to know. If I don't like my setup, I might just go the way you went, and for sure clutching to match the pipe helps a ton. Are you still running stock head shaved or a billet head? I'm also getting a maxicool head from aaen for the girdle kit to maximize reliability. How has your reliability been? Thanks!

Stock head shaved, if i did any more mods for power id probably brace the lower cylinder. Feels like 50hp but really i dont need much more than that is xc. The 700 lb machine is not nimble and takes a lot of upper body strength to tame in the turns

I was really getting pumped on that start.

Just as fast without it lol. Not as heavy as you think. Front end can come down off a 4 ft jump and not bottom out.

If you rode it yourself you would have a different opinion. Easily pulls a holeshot on modern racing quads.

Gotta keep these things flyin!

It ran perfect so im not sure what was painful? I have switches to activate the rev limiter in forward gear. Sold this rig not to long ago with a built engine.

Thank you! We have been blessed to be where we are.

How many acres is this trail on ?

@@michaelmangrum5460 The trail itself is 2.5 miles long atm. I have 40 acres of XC woodlands at my disposal. Quite a bit has not been used yet. Just gotta find time to blow the trail, condition it, and ride it down.

Sure was, luckily everyone was holding control.

Seal tensioning spring always faces the fluid. Good luck!

Is this what you are talking abput?

@@timothyzeimet4972 so the wire spring is face down...rt?

Please add me on facebook. I need pictures from you.

Are you talking about the seal?

That is actually a pinion bearing race driver tool, but works really well for the big seals. Sorry for the delay

Your correct. A extra rich condition on a 2 causes the combustion chamber temperature to plummet which doesnt allow a complete burn of the oil in the fuel. Look for worn or incorrect carb jetting and parts

With a 60 degree belhousing

HPD Trail pipe, aaen silencer, keihin 39mm carb, ritter clutch springs, air box delete, 91 octane klotz 40:1 pre mix, oil injection delete

And wiseco forged top end.

More to come soon on the more difficult repairs.

@@timothyzeimet4972 thanks, I have to do the rear strut seal as well. Any tips for that install? Currently have it apart with strut cleaned and hanging freely. Can I drive seal in with strut attached to quad?

We have a shop that does our rear shock work for racing so i have no experience with that.

@@timothyzeimet4972 not rear shock seal, rear strut seal. I have fluid leaking out of it and running onto my rotors and wheels.

Make sure the seal cavity is clean and install in the same process as the front. Even and flush to mounting surface. A seal driver kit would make this side installation way easier due to the recessed cavity.

Hello. So the spring will always face the fluid it is retaining. That being said their are 2 seals in these 4wd hubs. 1 for the hub shown in my how to and a seal that rides on the axle shaft that goes into the back of the strut. You may have the strut seal bad as well. When installing seals only drive them hard enough to get them to flush mount. Any harder will blow the tension spring off the seal and cause seal failure. Seal riding surfaces should be clean, smooth, and free of pitting.

Yes he did goes fast n didn't tell us which way it goes down.....did u fix ur leaks? Lmk.my way leaking thats why i change it but i will see if it leak....ty

I did "fix" the leak by removing the 6 moving parts and filled both hubs with grease. It's not 4x4 anymore and I don't care. When is the last time I used that function anyway (?) like never ...

I do not think so. Didnt see anything by the race trailer.

The question is.....why not. When you can sling a total assembly weight of 600lbs down a trail at 30mph and still get a podium finish its the best feeling in the world. What would you have done differently?

No problem!

If you are referring to the pilot air screw i have that 1.5 turns out. The mixture on the pilot circuit plays a big role in how the engine will respond to idle speed adjustments.

@@timothyzeimet4972 dang I ended up having to go back down on my jet because it was running like crap even at 1.5 turns out

You can get the fan and heater at harbor freight. I use it for my hands when they get too cold

Not for the dirt bike races.

Gopro 7 has no zoom feature when recording.

So the fat needle will run the fuel transition way too lean. I can get you the needle number i used on the xplorer. I do remember it was gold in color. Going to be doing a big shop update video today on a lot of scrambler upgrades ive done recently. Very exciting stuff. Thank you for the sub.

@@timothyzeimet4972 your welcome. I was at the polaris dealer today and the parts guy told me the needle that belongs on that carb is a , 6-DH29.the atv is stock otherwise. What brand winch is that ? And the switches on the dash must be for the winch? Thanks

Jet needle in my particular build is a 6CEY6. Slide is a 1.5.

The switches on the hat allow me to control the reverse rpm limiter in foreward gear for extreme offroading where reduced power is sufficient. The other switch allows me to bypass the rad fan on when crawling strenuous trails continually in low gear puts a strain on the cooling system.

The winch is a badlands 3500 zxr with a kfi industries winch mount.

You are very welcome

Thanks for noticing! It was my first time so just like anyone doing this sport for the first time you will be slow. 9 years of mechanics does a number on your joints and finishing 7th in my class without a stabilizer and not giving up was a major accomplishment. I can only get better from here on in. Thanks for watching. Keep in mind this race was 1.75 hours. I was on this machine riding this terrain for 1 hour 58 minutes non stop.

@@timothyzeimet4972 my bad g

You too! Hope to see you next year

That was my first time. It was so badass man. Good to see ya! Il be back next year if you guys run mountain grove again.

@@timothyzeimet4972 it was my first race as well! Awesome experience and I’ll definitely keep doing it till I can’t no more

Our 1st time too! Had a blast and hope to return.

This machine hasnt had a speed test yet. The motor got transferred to a 2000 scrambler. The scrambler ran 57mph but also had a HPD pipe on it.

As far as i can tell these gas rings were provided with the hpd pipe and the slip manifold. They appear to be pretty durable rings. Finding replacements may be impossible as high performance designs went under a long time ago. Seek out a man named Rick Ritter of ritter cycle racing. He may have some laying around.

No grease, use polaris demand drive fluid or type f automatic trans fluid.

@@timothyzeimet4972 thanks buddy hope all is well

Yes im doing great. We are prepparing for a cross country race at the end of this month

@@timothyzeimet4972good job, good luck

If you need to get ahold of me please reach out to my facebook messenger.

Thank you for the credit and support. More to come when i can get time.

@@timothyzeimet4972 I hear ya brother. Hip replacement next week. Trying to get all my winter stuff done before surgery. I’m in NJ . Crazy Busy at work.

Get well friend. Safe recovery.

@@timothyzeimet4972 thanks buddy I’m sure I’ll be talking to you for more advice lol .

Tim , one more thing I’m doing the seals as you know on my 2001 sportsman. My question is on the new Berings I’m putting in do I need to pack them with grease or will the demand fluid take care of the lubrication. Thanks Tom

I run the cover with all pipes connected. I also replaced the inner cover water seal behind the primary clutch. Belt stays dry in the creek and big puddles.

Installing the lower pipe required me to remove the inner clutch cover

Yes this hpd pipe rubs the stator cover and harness connector

@@timothyzeimet4972 did you get any extra noise from the clutch cover with the pipe install? I saw your video and mine makes a similar noise. I don’t think it’s bad, but it’s definitely louder than stock. (The clutch/belt)

@@georgeronquillo1851 so the hpd pipe has a standoff on the top that is supposed to have a vibra mount bolt that keeps it off the upper frame rail but its been rotted away and i havent designed a new one yet. It will make a pop pop when it bounces off.

@@georgeronquillo1851 You also need to be very mindful of piston slap on these machines. The cast piston "will" grenade the skirts and drop them in the crankcase. My 400 i built with a wiseco forged piston to fix the problem. I know a machine shop that does them perfectly and offers a kit with the work.

Glad i could help.

I ditched the Vm34ss carb that was on it due to wear. I purchased a mikuni vm34-275 i used the oem needle and cutaway slide and the needle clip at the very top. I used a 200 main, 30 pilot, and a br7es plug. This smoothed the transition through the circuits and made this machine very trailable even in extreme terrain. The plug is a tan color under any riding condition with the original expansion pipe

The gas guage is made by a company called kelch. Its not 100 percent accurate but give me a good idea of where my fuel level is at.

Thanks
