02 rm250


Recommended Posts

If its all stock, no need to, enless having some detonation probs. You could just to be safe but might need to be re- jetted though. I use an octane booster. But in todays fuels, their is etenol that 2T engines dont like. I just used premium with a little maxima octane booster and had no detenation probs. But my jetting was a tad on the rich side.

I had a '02 RM250 with a stock cylinder head and stock porting, but I did have a Boyesen Rad Valve and a FMF Fatty pipe. And that combination ran great on unleaded pump 92. If you have a local gas station pumping leaded 110 then you must be in an area where there's an automotive race track (circle or drag). In any case, I did try 110 leaded once and it was a waste of money. Plus just to get it to run right you will need to spend some serious time rejetting and then you are going to have to use it all the time.

My advise, stick with straight unleaded pump 92 mixed with your favorite oil somewhere between 32:1 and 40:1 and you'll be fine.
