budge66 Posted February 25, 2019 Report Share Posted February 25, 2019 Hi all just wondering what fuel mixture is best for a jt25 gas gas 1995, the bloke I bought the bike off said 40:1 and it smokes and spits oil out of the exhaust so have been running it at 50.1 but not a lot different so was wondering what ratio would be the best.

pjw123 Posted February 25, 2019 Report Share Posted February 25, 2019 70 or 80:1 quite OK with fully synthetic, Quote Link to comment Share on other sites More sharing options...

faussy Posted February 26, 2019 Report Share Posted February 26, 2019 (edited) Just remember you are forgoing a little smoke for running a 20+ year old bike on a fuel mixture it was never designed to be run on from the day it was manufactured. If it is spitting oil out the exhaust, you have bigger problems than 50:1, a bike wouldn't spit oil out at 30:1 Edited February 26, 2019 by faussy 1 Quote Link to comment Share on other sites More sharing options...
