Little help

[maggdog]

I put vf4's, jetted to 290 mains and 27.5 pilots, 4th clip position needle, actually airscrew is (1 1/2 turn out)...

 

Did 68.7mph top speed

 

2 things to help,

 

1- i don't know if is a correct setup on airscrew, so i need the correct turn out for this setup ^^^^^, elevation is 10ft sea level

 

2- i want to gain a little more top speed, i plain to change the rear sprocket for a fine change, i think change front sprocket is a big change so i don't wanna touch

 

actually is a 14/41, so i take advantage change rear because it need a new sprocket maybe 40 or 39? and also request the shifting very faster

 

I want the engine work in a balance not harder but either softer

Air screw will be a fine tune for your bike you gotta see what it wants.

Go ahead to a 15 up front
