Ok... I will compression check it and get back with results

Have not done a leak down test... I pull ONE of the carbs and it has a 290 main jet and a 25 pilot jet... Re jet or no reject?

Both plugs are fouling... It ran really well for the first few(3-4) start up/ rides

M & M Offroad in santee, ca. It's the old Presicion Concepts

When I did the break in on the new motor it ran and started every time very well... Then probably the 5-6th start up it started fouling plugs...

I'm pretty mechanically inclined... So pulling both carbs at once will be fine... I pulled and put the motor back in

Ok I will pull the carbs and check... And yes it did run fine before porting... I'll get back will jet size

I have a 2001Shee... FMF GOLD SERIES PIPES,stock carbs,boost bottle, air box has 2 silver dollar size holes, uni air filter, and it's been ported... Fouling plugs so I'm thinking it needs resetting I'm not sure what's in it now... Looking for help on figuring out what's happening and/or jet sizes... Thanks SHEE PEEPS!!
