Thought I'd have a go at enduro and bought a 1996 Yamaha WR200. Does anybody know what ration of oil to petrol I should be using, the guy I bought it from said 30:1 but this sounds a bit rich to me.

I haven't failed, I've found 10,000 ways that don't work.

I would go 50-1, but for safety try what he said first if he has owned the bike for a while he should know!

I have always used mix ratios based on the oil manufacturers recommendation and the type of riding application. For example I mixed Golden Spectro Oil or Duralube Oil at 50 to 1 in my Yamaha YZ125 or YZ250 off road bike but mixed the same oil at 70 to 1 in my GG300 Pro. In general Trials applications can run a much leaner fuel to oil ratio than off road or MX bikes.
