Hey guys Im new to the site. I was wanting to get some input on what the best synethic oil to use in a 800 outlander that has a 843 JE piston kit, aftermarket cams, hmf exhaust,snorkels and clutch work done. Bike runs 8100 rpms in mud races or on trails. that is top rpm. We have ran it flat out on pavement an it hit 90mph. It has alot of torgue. Never been on a dyno, but with the info added up we have been told it should be putting out about 85 at the crank and roughly 72ish on the ground. Those are estimated on paper. I'm looking for a off the shelf oil and concerned about foaming at the higher rpm. Any thoughts?
