How much money is SL2 exactly? I use H1R and I have been getting great results so far. Spooge cleaned up nicely as well :)
I get 6 packs of little 12.8 oz H1R bottles for 20$ a 6-pack at Rocky Mountain ATV/MC online, and I run it 36:1 but you can even go leaner with that. I know people that use it that run it 50:1, which is actually what Bel Ray reccomends for it! :)
I have always liked to run full synthetic in every bike I own, and *knock on wood* I have never had a problem with any of my, or my families bikes or quads in our lifetime besides minor non-engine related problems :)
