Flywheel Weights on a 125?

[02Dale]

I ride my 2000 RM 125 in tight trails and race harescrambles once in a while. I would like to kill the hit a little, and have better power on hills.

I've read that weights don't work well on anything under 250cc, is this true?
Does anyone use a flywheel weight on thier 125?
If so, did it help and what weight did you go with. I'm not sure if I should go with the 8 or 10oz.

Thanks!

i don't have a flywheel weight on a bike, but the bike I am getting (kx100) everybody says to get a flywheel weight to tame it in the woods

so I guess it would be good on a 125 also
