Re: opti-2 I'm sold on it.
Well my machine is running so good on this stuff. I have up'ed the the main jet to #76 (.76mm) and for some reason I kept on lowering the clip on the needle from the std. second spot down and it just kept going better and better. Now its on the bottom slot, ie. the richest, and its going great. Still only done 200km's so I am only taking it easy but this stuff is great.
