[dodgeram18]

Hey guys I recently rebuilt my 08 800xp with cylinders, dual ring pistons, slp hill climb head. I was wondering if i need to rejet my carbs after installing this slp head? im not sure what compression this head is. 13:1? but im looking for some insight on jets will my stock ones work or do i need to up jets and to what size of i need to? thanks in advance guys.

I would call SLP and let them know the engine combination that you are running. They might have a set up for it already. If not I would start by adding a little bigger jet then test.

Some heads need smaller jets! You could look online at slp website might have some info.

Jet up!!!! Start at 500s

As per SLP site, up 1 main jet size and .020 needle shim washer under the e-clip needle for non-ethonal fuel and up 2 main jet sizes and 2x.020 needle shims for ethonal - minimum 91 non-ethonal fuel required.

Thanks guys! its a lil underpowered in the bottom end but pulls nice in the top end. until i pull the carbs off for a jet set ill just have to keep my revs up on the hill.
