OK my problem is, I removed my air box and went with a hiflow air filter setup. I still have the stock pipe on. I have gone from a 130 main all the way to a 147.5 main and the bike still cuts out at about 2/3 throttle. With the choke on about half way it is better. Does this mean I still need to go bigger on the main? Or do I need to adjust something else? Like the pilot or needle setting? Thanks

 

Lean on the needle. The only way to raise the stock needle is to get some tiny washers & shim it up. Otherwise you'll be buying an aftermarket adjustable needle.

 

I decided I'm just going to take it to ALBA and let them pipe and rejet it. Thanks for your help.

 

yup its the needle...you should definatly put an exhaust system on and rejet it. is it real cold where you live?? if so you might need to change the jets when it warms up...

 

No it is not real cold. I live in San Diego. I took my bike to the shop today and am having a WHITE BROTHERS ALUMINUM PRO II installed plus jet kit and all dialed in. [img]i/expressions/face-icon-small-happy.gif[/img]
