I know and understand that jetting cannot be done via internet forums, but I would like an idea what others think on where I should start.
Machine history is really unknown.
What I do know!
Fresh top end at 1.00 over(68mm)
New Boysen reeds
PSI exhaust
FMF Q series silencer
stock carb
Uni airfilter with outerwear air box cover and factory airbox lid w/ holes
The machine started and ran before motor removal. It pulled good and hard, but it would flutter after coming off 3/4 to full throttle. I would need to nurse the throttle to keep it from bogging out completely. While at 3/4 to full throttle she was fine, and the same goes for the rest of the range. It was just when coming down.
That may contribute to a leaking main crank oil seal.
Anyways here is what the carb is currently set at:
Needle 4th clip as called for in the manual
162 main where as stock calls for a 150
58 slow where factory was a 48
I have fouled a total of 2 plugs with only around 3 hours of total run time. The oversized main may explain that!!!
Thoughts on a good starting point?
