[QUOTE="BradFrost, post: 885359, member: 58022"] I use Motul Factory Line 800. Only time will tell you the right oil for your work. Even though I've been guilty of running 200 plus hours on two-strokes before when doing the top or bottom I'd always choose a new piston. It's the guts of the motor and the rings and piston tolerances really do matter and bed into each other. BTW I only got 200 + hours outta the bike coz I chose my fluid and filter maintenance intervals carefully and stuck to the schedule with premium products. Another idea for you might be to jack you bike up ...securely.... and then kick it over and try and find the rev band that the noise starts in while having a good listen from somewhere other than the seat. Rest the handle of a large flat head screw driver on your ear and touch various sections all over the motor and try and narrow down where it's comming from. You might wanna park the arse of the bike out garage and partially shut the door on it to cut down the exhaust noise while you play doctor. A Gclamp will hold the throttle in postion if you've got Barkbusters or whatever you call em. [/QUOTE]
