Title: oversized pistons& rejeting question
Post by: im your legacy on August 27, 2008, 11:49:18 PM
I have been trying to figure out using the proper jet size? for my new build which is using a piston size one up from factory. I'm living at sea level right now .

I'm planing on eventually putting on a yoshi slip on or a Jardine exhuast? But i hear you'll have to use larger size jets if using a complete " bolt on " exhuast system.  According to the chart if i were to upgrade to a K&N lunch box air filter or a drop in.  The jet sizes should be around  pilot 22.5,mid-main 65,main 147.5?  As for now i may just go for a Yoshi slip on a a K&N drop in filter.

 
Any advice would be appreciated alot.

Thanks,Will......

You probably want a snorkel on the airbox, and give the whole thing a good spray of WD40.

If you're just going one size up for a rebore, don't worry about your jetting changing much because of it.  Pretend it's stock bore.
