If not, if you have well over 200 miles on it and it's still vibrating like **** - perhaps it's not mounted as securely as it could be? Excessive vibration can cause fuel frothing in the carb making it run worse, an annoying cycle if there ever was one (mine took over 300mi to break in, I blame good oil).
Stuff to look at;
plug coloration and fuel/air mix
air leaks
properly sized gaskets*
centered rear sprocket
It does really sound like yer motor is just still "too new" though, that's an easy fix 
*The center hole in these gaskets is usually far smaller than their respective manifolds, make sure the hole is as big around as the inside diameter of the pipe it goes to. |
Perhaps it's not broken in enough, yet. I thought it was broken in because I saw a significant change in torque over the first thee-four tanks and haven't noticed much change since.
I do feel I was running a little too rich because when I would turn the fuel valve off and let the engine die on it's own it would rev up right at the last second before it died. According to many these forums that indicates a rich condition. I moved the needle down one notch last week and now it doesn't rev right before dying when I close the fuel valve. I had been checking the plug color every so often and it looked good (at least I thought it did) so I thought my mixture was good. Perhaps it should have been a lighter color brown. I'm going to keep checking the plug now that the needle is in the second position and see how that goes.
I checked the exhaust gasket (haven't got around to checking the intake gasket yet) and its really close to the same size as the exhaust manifold. The exhaust pipe connection on the other hand is smaller than the manifold but there's not much left to widen the hole. I did, however; drill (5) 3/16 holes in the end of the pipe and it helps my acceleration significantly. Perhaps I'll start to see fuel economy go up now?
Either way, I really enjoy riding this bike and look forward to many more miles in the future.
