Per Other riders recommendation, I recently switched to Castrol tts. As they suggested, the bike is snappier in the low end and is "smokeless" when running 40:1 or better. Does anyone else run this oil and how do the valves & top end look when disassembled? Thanks for your input!
I use it.Done 2 top end rebuilds (maintainance) while been on the stuff and found power valves easy to clean not so much crud on them.
running at 35:1 and with my bike jetted correct little/no smoke or spooge.
It's cheap can get it anywhere so I'm a happy customer.
