    1990 with a cleaned carb,jetted and 3 washers under the needle and it runs the same as stock. On a small digital tach it just doesn't seem to want to rev much past 7400rpm's and 50mph without the stumble,bog that feels like a rev limiter kicking in , also in nuetral it will rev out nice and smooth till it gets around 6k then start to struggle. I'm starting to think it might be a coil pack or cdi ?

    I believe the redline is 9500rpm.
    '13 690 Enduro R too many frickin farkles...
    '07 KLX250 farkled (wife's bike)
    '86 BW80 farkled to size
    '10 TW200 you will be missed

    As i stated in the original post, the bike runs with the same problem on stock 114 jetting and stock needle position as well as 3 washaers and a 120 main. Not a rich issues as it is the same trouble either way .

    I had a similar problem and it turned to be a gas venting issue. I removed the tumblers from the tank cap( 2 screws) and that seemed to fix the problem.( I also like the fact you dont need a key to fill up.) Give it a shot you can always reverse the "fix." Also for those that have a tank bag , be sure you are not smothering the cap vent with the bag. I only say , cause I have.

    The cap vent was one of the first things I checked , I cleaned the tiny holes and if you turn the petcock on you get a ton of flow into a container so that is off the list, I ordered a aftermarket coil pack it try so for $20 it is a cheap test to rule the coil out .

    Well no wonder this little bike won't go over 50mph I'm missing a couple thousand RPM's on the top end ,it won't go over 7500+or- a few hundred .
