Jetting ?

[DirtDiggler]

I have a white bros e-series slip on and I run a uni air filter. The guy who I bought it from said with that pipe you don't need to rejet. The white bros site said you don't need to rejet unless you do other mods and the air filter is one of them. I was also thinking about getting a vented air box lid. I live in western NY and was wondering if anyone had any jetting advice for either set up.

Thanks in advance for all advice cause this kid aint no mechanic.

look back thru the previous post, maybe a couple pages back "pipe shootout" dirtwheels tested about 10 different pipes, they ran a 155 main for your pipe, that's a good starting point
