    My 93 exhibited similar but not exact symptoms. Mine would "stutter" and overall have no power at high RPM. After checking the carb/cleaning a half dozen times, replaced the reeds, cleaned and inspected the PV, new gaskets and crank seal, new spark plug, cleaned the exhaust and repacked, checked for spark/timing all good I was about to throw in the towel. For giggles, I replaced the stator (even though it showed spark) and low and behold the beast was back from the grave and about bucked me off when I first rode it. Just throwing there out for others that instead of mechanical or fuel/air, check the electrical side of things. I was about to sell it as I was so aggravated. Hang in there Joe. I really enjoy our video's and unless you are Jett's mechanic, I think we are all learning along the way on our own bikes too. It's a constant learning process.

      I had same exact experience that ended up being the flywheel. Stator, flywheel, regulator rectifier, CDI, coils, leads, caps, SOO many things that could cause this that he has not checked.

    So i'm not sure if anyone missed it or not, but at 38:00 and a bit after, that screw boss just above the crank primary gear is broken, and if you look close through the hole, it goes directly into the crank housing. This is another source of an air leak as it's sucking air from inside the clutch cover. I was originally going to say crank seal, but considering the few already found rebuild faults, this engine has been abused a few too many times.
    Joe I think this needs a full teardown. Someone did not know what they were doing before you picked it up.
    Edit: Also that crank seal is bad. When you were pushing the sleeve back in it was pushing oil out on the bottom. Either there is a tear somewhere or it's not round and not sealing the outside rim. If you look closely down by 6 o'clock it looks like someone punched a divot into the seal boss, probably from installing it with a flathead screwdriver.

    The trouble shooting section of my ‘00 CR250r manual says for poor performance at high speed check the ignition timing. Possibles causes: alternator, faulty ignition control module, faulty ignition pulse generator.
    Thinking years back when I got my CR250, the power valve was adjusted to be open all the time. The motor had no low end power but did not bog like that on the high end.
    These bikes are a blast and worth the effort.

      I dont think crank seal. If clutch side it will smoke. Stator side revs be all over the place. Im 💯 sure its stator. Ive tested these before and had right results! Ktm are the worse to diagnose. They give right readings and fail at high rpm. Its almost impossible to diagnose. So its not a air leak from seal crack or whatever.

    I stand by my comment in the last vid - sounds like it's dropping spark at high RPM. You can hear it popping off, power valves/fuel would be a consistent bog. Start with a new coil, but honestly have a CDI and stator sourced if you need it. More electrical diagnostic work needed 👍

    I commented on your last video. Good job on figuring out the powervalve. But it's your carburetor. The emulsion tube where the needle runs is wore out. Doesn't matter what jetting you put in it'll never be right. I had the same issue on the same year bike. You need a new carb.

    I've had a similar problem in the past and it was due to lack of back pressure in the exhaust. It actually sounded worse this time which would make sense being that the rest of the packing is gone. Its very possible that you fixed one problem (power valve) but with the packing removed caused a similar problem

    Try removing the pv all together. If it runs great at mid to top end with all the power than you have found the only issue is the pv system. A pv system is designed to give added power to the low and mid range.

    • @ar2043
      @ar2043 12 дней назад +6

      This here ⬆️ We used to do that all the time on the older Ski-Doos and Sea-Doos with the exhaust valves. If we suspected a top end problem with them not opening all the way, we would simply remove the springs and let them go wide open and at least we would know if it was the problem or not. It would run like pig shit on the bottom but it was only for testing the top end. Do this…
      Also with the watercraft, we would have instances with the PVL stators and CDI's Breaking up intermittently/when they got warm even though they tested OK. Something to put in your bag of tricks anyway. Worth a shot.

    I had the same problem with my 94. Your power valve is not operating correctly. I was able to adjust it from the upper cylinder.Has to be that the "governor-ac tuator is sticking. Next time you have the clutch cover off please go over the kick start gear and why it would skip every 4 or 5 kicks. Great entertaining vids!!

  • @alastaircarr8518

    Used to race these from '93 to '96, great bikes especially the "93. Spotted the bad exhaust valve bearing as soon as you pulled the cover. The exhaust valves on those needed regular servicing because the valve itself was made of steel and unlike aluminium didnt shed heat very well so they tended to carbon up and stick. Also the slot in the valve used to get build up at both ends eventually not allowing the valve to fully open or close. If memory serves, there isn't supposed to be a stud holding the water pump cover on, thats a bodge job from a previous owner, also there should be two dowel pins to align the cover I think one was eliminated due to the stud. Also there is supposed to be a separator between the two water pump gaskets, I don't think i saw one. The center case is broken where a clutch cover bolt threads in near the transfer port channel, hard to tell if that hole goes all the way through, its supposed to be a blind hole, I think I saw some sealer in the channel where that hole would come through. I'll bet someone put a bolt in that hole that was too long, tightened it and broke through the case. Clutch basket looks hammered, if the clutch drags you know the cause. You really should get the right washer for the clutch, that one is too small on the O.D. and what about the thickness. Theres supposed to be a plastic keeper under the carb spring to retain the cable in its holder, didn't see it. I think you are correct and the power valve now isn't opening. Its been a long time but I think you are a tooth off on the shaft in the case. Lift the cylinder then pull the rod up and rotate it clockwise one tooth then drop it back in. Take the pin out of the top of the power valve shaft in the cylinder, loosen the allen bolt and let the shaft drop down just far enough so you can see it below the cylinder this way you will be able to see the fork drop onto the pin before the cylinder seats on the gasket. You need to sort where the metal flakes are coming from. It looks like aluminum and since there were no signs of wear under the clutch cover and it looks like the bottom end is new I'd guess theres a shim missing from the end of a shaft or a gear on backwards rubbing against the case. I know you said the reeds were perfect but I wish you would have shown them. Based on everything we've seen thus far its obvious whoever worked on this last shouldn't be allowed to own tools. Last thing that rear tire looks like its off a 125. Looking forward to the next vid on this bike when you get it all sorted.

    I think the stock position for the needle's clip, would be the middle one and these bikes are shipped, set for sea level. The average elevation in Wisconsin is 988 ft. above sea level with the minimum of 564 ft. and the maximum of 1,909 ft. At those elevations, you might consider placing the clip back in the second place from the top. The clip position doesn't affect wide open throttle position, but does at mid throttle positions. At wide open, the needle is out of the jet. I'd check to see what main and pilot jet recommendations for your elevation are as well. The best place to begin. I'm surprised that no one could diagnose and fix the problem. The bike finally ended up in the right hands, Joe the engineer, busman and "can do" mechanic. You're ruling out what isn't wrong and working your way down the list, repairing what is wrong. Won't be long 'till the bike is in tip top condition. Following this one. Great job Joe :)

    Had the same exact problem with my yz250. Replaced reeds, intake boot, rejetting, tried a lectron, and replaced everything electrical. Still had the same problem. Turns out even though my timing marks were aligned, you still need to advance timing to spec. In my case a yz250 spec was .07 advanced. I also replaced dry side crank seal even though it was 2 months old and all my problems were fixed. So try to replace your seals and check your timing

  • @joemomma9177
    @joemomma9177 12 дней назад +5

    I honestly think that you have a vacuum leak. Either from the carb itself or from the JB weld or one of the seals. It would explain why changing the jets did nothing. The more you rev the more air gets sucked in rather than creating a stronger vacuum which helps make more power.

  • @craigroberts3843
    @craigroberts3843 8 дней назад

    Had 6 of these bikes the bogging is because the power valve was stuck open. The reason it's now not revving out is because the power valve is not opening. When putting the cylinder back on you have to make sure the pin at the bottom of the rod goes in-between the 2 fork prongs on the rod that comes up from the crankcase. Can be quite tricky to get it lined up correctly. I actually brought a 96 model that wasn't revving out just like yours is and it was because the pin wasn't lined up in-between the 2 fork prongs

    As I said in your last video about this bike, you should try holding the throttle at a steady RPM spray some starting fluid where it's been JB welded, and see if it revs higher.... I am gonna stick to that theory..Also, your spark plug should be tightened to the correct torque specs... I'm guessing that you do a lot of that "off camera" but, your spark plug was loosening while free revving... just saying... Love your channel Joe, please keep us updated! Thanks...

    Do a Leak down test. I just fixed an old Suzuki ts400 after doing a top end rebuild messed up the base gasket, somehow. It would run out of fuel and Die after 3/4 throttle. I went to the biggest main jet I could find but still would run out of fuel. Doing a leak down test I found out the base gasket on bottom of cylinder was leaking on both sides front and back of cylinder with only 6 psi it was bubbling the soapy liquid I sprayed all around it.
    Good luck I like your video's.
