Can anyone tell me where the best/least expensive place to buy sprockets is??? I want to give our tb330 a little more help for the atv pulls this summer, so that it might actually spin the rear tires on a wet clay track instead of just smoking the belt. I know these things don't make a ton of power, but thought if I changed to smaller front/larger rear sprockets and got a little more aggressive with the clutching than we might have a chance! My son doesn't want to get beat by the ex400 again!

 

check out Rocky Mountain atv, they have'em cheap!

 

They don't list any sprockets for the trailboss 325 or 330. Are there any machines that share the same sprockets? Any ideas how I can improve the belt grip to keep the belt from smoking???

 

dano, any of the sprockets listed 11, 12, or 13 tooth for the tb, scrambler almost whatever except predator will be the same spline and fit your machine. same goes with the axle sprocket. for instance you could run an 11 - 40, 12 - 42, or whatever combo you come up with. as for the belt you can use a slightly heavier secondary spring or go with a clutch kit for it.

 

There is a guy who goes by sledpartsguy on ebay (I think that's his name). Got my rear sprocket for under 20 bucks including shipping.
