So I drained the transmission fluid from my jawa, refilled with 4oz of Dexron III, tightend everything up and took it for a ride around the block. It idles perfectly, and runs at a slow speed well. When I try to accelerate it to half or full throttle, the bike 'bucks', like it's try to grab and pull me faster, but something is stopping it. If I ride it for say five minutes, it will also start to buck at slower speed. It never actually 'bogs', as in it dosent feel like it wants to stall, it just sort of dosent want to pull it's weight (or mine).
When I get back to my garage, the top of the transmission is coated with ATF oil where it has apparently leaked from a hole in the transmisson fill plug. In the bolt that acts as the fill plug there is a hole in the center of the slot across the top of the bolt.
My questions are
a) what is this hole for
b) is tranny fluid supposed to leak from it?
c) if not, what is causing it to leak from that hole.
d) does this sound like a tranny problem, clutch problem or just another "take teh carb apart and clean it again" scenario.
The jawa does not have an air filter, I had the petcock apart and cleaned, I have installed a new fuel line and fuel filter, and I've cleaned the carb very well (at the same time I added the fuel filter) I have not had teh clutch cover off yet so I'm not sure what is going on in there but I do here some metalic pinging coming from in side when the cluth first starts to grab and also I think I hear it after it bucks and tries to catch again.
