I am going to get a clamp on filter for my predator in a couple days and am wondering what i should jet it up to main & pilot, my current mods are a Nicholas cycle drag pipe and a rath racing header. im running a 160 main in it rite now and it runs strong as an ox with no misses. One thing im worried about is i herd that if you get a clampon it messes up you vacume and your throttle wolnt open the whole way is that true? any help thanks

 

Rob, once you get your clamp on, I'd run a 172.5 main jet, and a 50 pilot jet. It is true about the carb........if you get Doug's carb mods, then you'll be just fine, but otherwise, you'll have to go with a rath racing type intake.........

 

what is it not enough vacume to open it all the way or what? No sence in getting a clampon until i get my carb sent to doug then i guess ill call him tommorow and see what he has to say. whats he do that lets it open and what are you runnin for a filter bradracer
