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. TIA

70 or 80:1  quite OK with fully synthetic,

Cheers for that ?

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
