no top end after jet kit installed

[Guest]

so i have an 80 750 with pods and a 4-1.... blah blah stupid cafe racer.

after i installed the dynojet stage 3 kit, it idles great and accelerates smoothly until i get to about 6k rpm. then it just wont go any more.

i have moved the need spacing through all the options. its currently at 2nd from the top. i found that this lets me get to at least 6 or 7k rpms instead of 5.

the main jets are 130 my guess is that they need to be bigger 135 or 140?

DJ kits come with 2 different size mains, have you tried both sizes?

Full throttle? Partial throttle? When it stops accelerating is it rich or lean?

[bartmancometh]

its at about half throttle. i dont know if its lean or rich. no back fireing or anything when i let off.

Did you install the main air correctors? They are included in the kit.

From around 3/4 throttle to open you're on the main jet. You need to try one way or the other size wise. The problem will either get better or much worse.
