Superjet carbs jetting
I am looking for some help please!! I just modified my engine and don't know how to tune my carbs...
Here is what I have :
- Stock mikuni BN38 carbs with stock jetting (130 main - 70 pilot - don't know what the spring load is)
- Prok air filter with adapters
- Factory Modified B pipe, with dual cooling and ported exhaust manifold
- ADA girdled head with 35cc domes
- V force 3 reed valves
Can someone please help me choose the best jetting setup for my carbs please ??
Thanks a lot!

Attached is a diagram I pulled off Wamilton's site for the dual cooling mod, & it has his jetting recommendation at the bottom. You'll probably have better luck posting on this forum with SJ questions because there aren't many stand-up riders on the Hulk:

Thank you! I already had that diagram, but this jetting specs is only for the pipe mod... I think I must install some bigger jets, as the v force reeds and modified intake will allow more air to enter the engine... And more air means more fuel needed..
Good idea!! I'll ask that question in the x-h2o forum
Thanks a lot!
