I just got my nephew an RM80. He is 5'7" 120 lbs.

I took him out one time to a desert area that was very dry and the dirt was soft. He was fishtailing on most hills.

What would you all recommend for a flywheel weight se he can get the power to the ground better without lighting up the rear tire?

I'd like to take him on some trails also

13 oz?
17 oz?

Thanks in advance

There is no 2003 RM 80. If the year is correct, then it's an 85.

In any case, I don't know of anyone that makes a flywheel weight for these bikes. They are pretty smooth and I'm sure there is little demand for a weight.

You might try turning the powervalve spring pre-load adjuster in a quarter turn.

I would recomend a fresh rear tire and more seat time. It sounds more like either a bad tire or lack of experence than a bike issue. That said, my wife rides a KX105 (stroked 100) in tight woods. I added a 12oz stealhy flywheel weight. This made the hit less abrupt and it hooks up much better when accelerating out of tight slipery turns. I suspect that stealhy offroad has a weight for the RM too. I would think that 10-12oz would be about right. My sister races a KX107 (bored non-powervalved 100) in harescrambles. Her motor is ported, high comp etc with FMF exhaust and no additional flywheel weight. It hits pretty hard but she is very experenced and gets around quite well (she won the HS championship for our district). Amazingly, she does very very well on steep slipery hills, showing up the vet A guys in our club on a regular basis.

good luck

Oh well. You could go to steal clutch plates inplace of the aluminum ones for a little more flywheel affect. Still, I suspect that a little more practice might be the cure:)

Both good suggestions. :nod:
