no power

well I just got back from the race and in the middle of the race when I let out of the throttle it would make a popping sound and would struggle getting up to powerband but when it did ot took off but till it hits powerband it struggles alot and I melted my brake line in the middle of the race to I had to finnish the race with no brakes and race another race with no brakes
 
The guy that did the porting should be able to tell you on that one. With all jetting, start well above what you think you'll need and work your way down. Get 5 sizes up from stock and you'll have almost every pilot you'll ever need (unless you go big carb).
 
Very seldom do you need to change the pilot from the stock one.

If it is popping on overrun I fear that the idle is incorrectly adjusted.
