if they are on a basically stock engine with just bolt-ons do you need to upgrade injectors? i know the itb's wont get me that much so dont tell me to spend my money elsewhere...... im just gonna attempt the diy motorcycle itb's so it wont be that much of a waste of money if it sucks. thanks for any help

 

I don't think it's a necessity, but being that you should be tuning the whole thing, it's not a bad idea. I'd get some larger ones.

 

do you think some h22's would be enough of an upgrade?

 

ITB will be overkill if you only have boltons.

Trust me - I know.

I run 370cc injectors w/ mine.
