I am tired of getting spanked...
My friend has a 400z with a full curtis sparks race exhaust and jet kit and when we race he walks away from me. In a 1/4 mile he usually beats me by 4 quad lengths. Do you guys have problems beating the 400z in a race? This is what I have done to my 400ex:
Full FMF exhaust
165 main jet
curtis sparks 6 degree timing advance
K and N air filter
Air box lid mod (has a 3 inch hole in it)
Hot Cam stage 2
10:1 high compression piston
I do have 1 inch bigger diameter tires in the front with the .190 wall thickness, could that really be slowing me down?
I need help!
