Had overheating issues and this coolant is the #1 recommendation I found across the web, I also added an electric fan. So far so good. For the price I dont know why anyone would choose anything else.

K & n cleaner works great getting the filter clean the first try.

Yamabond 4 seems to handle the heat a lot better than permatex and others I have used. I use it where the stator harness goes thru the stator housing. No leaks!

I absolutely love this stuff. I have run it in all my 2-strokes for over a decade and will continue to do so. I have never had an ounce of issue with this oil, and it keeps the top end looking pristine. Plus, you just can't beat that classic Klotz smell at the track or on the trail. 2 strokes for life!!!!

Castor 927 is the best of the best. Rocky Mountain got me restocked quickly.
