Im running 148 and 52 pilots with snipers. That being said it will be way off with any other pipe. If i put on Shearer pipes its a drastic change in jetting
Your main and pilot jets seem massive. I would think 27.5 pilot and max 300 main.
too much has is my guess. Does it have drag type porting or is it stroked?
Put a case saver on it.
The sky’s the minor with these machines. A huge upgrade would be new a arms and suspension up front. If you want more power the stock cylinders and carbs are just fine and will produce 75 hp with pipes and porting.
First thing I thought was your mains are too big.
How does it start? And is the power loss all the way through the throttle range?
check your compression
Lots of torque! Pro Circuits surprised the hell out of me.
Im curious to what pipe youll end up with and if you trail ride why didnt you consider SLP for even more torque?
