KX500 AF Running like a 200
RKPerformance:
I'll get pics up for ya'll when it quits raining and snowing here! I went out took the governor rod cover off and checked valve operation again and it sure seems to be going out and in just fine. The carb is a 40.5mm bored PWK. How does a bigger carb affect the jetting? Does anyone know what kind of main and needle a guy would run with this carb? That might be why it has a kx250 needle in it. I finally figured out a way to get the cr pipe to get in there but it needs quite a bit of denting to get it runable. then i will be on to figuring out the cr5 silencer, which i dont think will be to bad to get to mount up. :evil:

that sounds, that you slowly find the way to finish this problem... :wink:
question: it snows and rains also inside your garage, if you want to make the pics?? :lol:.... the kawasaki-doctor-team need no pro-pics to see the bike with the wrong exhaust and details of your fitting problems with the cr500-pipe . 8-)
...big bored carbs like your 40mm pwk or bigger are used for more airflow which makes sure, that the bike runs well in higher rpmīs like its needed for example in highspeed-runs.
for use on small mx-tracks or wood-riding, where is much power from bottom needed are smaller carbs like the stock 39mm or a 38mm in use on the k5.

Like reading this thread . But I don't think my problem is crankcase seal related .

i just got mine back togeather and it was running super lazy.. so i checked the plug and it was fine... so i got to thinking about timming, so i looked in my manual of how to set the timming up... when i pulled the flywheel off sure enough it was fully retarded... now its back at the factory marks and the bike runs great... so mabey u guys can check your timming..

you can timing night and day, but a 500 will never run properly with a 250 pipe...cause the expansion chamber is much to small. thats the point,that we turning around ... timing and eventual jetting are the steps 2 and 3 after installing the right expansion chamber. and i think, if this 3 steps are done the beast awakes with its true powers... :-D
