brewtus Posted March 30, 2018 Report Share Posted March 30, 2018 Avgas/Motul 800 at 60:1 in my TY80s and my 305. Quote Link to comment Share on other sites More sharing options...
pmk Posted March 31, 2018 Report Share Posted March 31, 2018 Avgas and Maxima Formula K2 in both the 73 OSSA MAR and the Scorpa SY250R. I take a beating about mixing and running 50:1, but have no spooge with proper jetting, and after talking with Maxima, opted away from anything less oil than 50:1. Yamaha and Scorpa wanted 40:1 in the SY. Quote Link to comment Share on other sites More sharing options...

suzuki250 Posted March 31, 2018 Report Share Posted March 31, 2018 I run my air-cooled bikes at 40:1 never had a problem. I fact I've just had a look down the barrel of my Suzuki and I can still see the honing pattern after 10 years running! Quote Link to comment Share on other sites More sharing options...
