Acceleration

[bvmracing]

Does anyone know how to make stock DRR's accelerate hard?
We have a stock 90cc and a 70cc aircooled. Tried a few differant springs but cannot seem to get it right.
Purpose is for mx style tracks.

Any help would be great.

have you tried playing with the gearing, that should wake it up.

18T sprocket up front

4.7 rollers.

1500 torque spring

2000 stall springs.

Keihin pe24 carb with jetting changes

That was with a stock aircooled motor.

I am by all means a rookie, but it kept up with any other stock motor on a straightaway.

The above is for a 90cc

Hope this helps you get started.

Thanks guys, I will try the gearing and springs.

Remember, the most important thing on these little quads is one change at a time.

We had a similar problem. Gary was able to get us on the right track.
