Jetting help needed

[kazpr]

Ok I am running sparks cam, 13:1 piston, ported head, big core pipe, no airbox lid, hrc needle 3rd clip, 50 pilot and 190 main. Problem is from 1/2 to full throttle it just cuts out BAD!!
This is @ a stand still in nuetral. No dyno close to me @ all. :(
Thanks alot for advice.

It's not the rev limiter? I'd try it in gear. Your main sounds really rich for a 13:1 piston. I'd try a 180, or less.

Ya off to ride now :)

How was the ride? Did you go try a smaller main jet yet? Let us know how it all works out.

Before I had a 180 and upped it to a 190 and seemed like it was about dead on now! Wow the rev limiter comes way to quick with the new mods. But that mofo RIPS!! Thanks for the help.
