What jetting would you suggest that I start with? I've seen several guys with mods identical to mine, and it seems like the jetting really varies a lot.
Stock 2005 motor (all new internals), cam mod, full Yosh RS-7 exhaust, Boysen Quick-Shot pump cover, stock intake with K&N and no airbox lid.
I bought this YFZ with a locked up motor, so it wasn't running when I got it. The previous owner said he jetted it and it ran good.....but who knows.
Currently it's got a 158 main, 42 pilot, and the stock needle (I think) with the clip in the middle....3rd position I think. When I pulled the motor apart, the top of the piston and head looked pretty black...so I don't think it was lean.
From what I've seen...some guys with these mods are running as small as a 150 main, and some go as big as a 168 main. The pilot jets all seem to be around a 42-45.
What would be a good starting point? I'm at 900ft.
Thanks!
