Jetting help with new mods.

Ok I have a predator 90, No one answers question in the Polaris section.

It is a 06 2 stroke. I put on a new big bore to 53mm . My head sits at .050 I have a uni filter on now. My stock jetting was 82.5 and 18 I believe. I have tried 25 idle jet and a 95 main. It felt sluggish but better than the 90 main. I taped the jet to in the area of 110. Guessing. It runs better but still feels like it is not tuned correct. I don't know a thing about the clutch. Any advice on jetting. I am at 4000 ASL. Lake motors said 25 ad 95 so I am in the range.

What kind of clutching would be best for sand. My girl is about 80 lbs.

Well I got it running good. I drilled the jet out to who knows 115

I don't know much about the clutch except it is stock. It felt like the transition was holding the quad back.. Like it takes off and then slows in acceleration at mid to high rpm then it picks back up some.

Thanks for posting.
