Who is running a heavyer than stock crank, or a heavyer fly wheel, and or both, and if you really noticed the difference on the track. I suspect that you can get on the gas earlyer and get better drive, but thet wont rev out as quick, which for SM is better. Any info would be appreciated.

Hi- Jumby -

Yep a heaver fly wheel will smooth out power curve -

Instead of adding heaver flywheel I gear my final drive Taller -
Larger counter shaft sprocket -and or -
smaller rear sprocket --

this gives you some some adjustment to power curve also --
so you can dial it in -
you can still have quick revs when needed by slipping the clutch-

First gear is mostly useless anyways - so set final drive gearing so that
1st gear is about the same as 2nd gear would be in stock setup -

I gear Taller for race day than for practice days -- Jay--

I think this is the reason the Husky SMR models have the counter balancer on the crank and the woods and MX models do not.
Now I have never rode a Husky 450 that did not have this as all I have rode was other 450 and 510 SMR models, so I cant say how much of an improvement it is.

Thanks, for the info guys. I run tall gearing at our local track 14/45, I have even run 15/44 it has 2 long fast sections. The problem is getting on the gas, if I get on it too early it spins up fast and i cant control the slide. I have had the bike come around on me a few times, and had it buck me off the seat enough times that I am getting a little nervous. Slipping the clutch may work, but may require a sponcership from Barnett, haha. My motor is built and the torque curve is steep, this could be part of the problem too. I am ordering a dirt tracker crank from falicon maybe it will help.
