sproket size

[ThorR88]

Hey i have 18inche back tires 19 inch in the front i race mx i wanted to know what is the best sproket size to run thanks

[jasoncarr25]

depends on motor work that is done and condition of the track

[ThorR88]

I have no motor work done

[jasoncarr25]

i have same tire set up as you and i always liked the stock setup.(sprocket)

[ThorR88]

i heard it runs good with 16 40?

[cals400ex]

16/40 will be slightly higher gearing than stock. i personally like higher gearing. i actually run 16/36 with my motor. it isn't stock though. i like the speed up top. you won't want to go higher than a few sizes in the rear or one size up front on a stock motor.

i just want something good for mx racing

[EvilJester400EX]

16-38

[jasoncarr25]

if the track is tight leave stock gearing,if track has alot of wide open straights go with 16- 38. this is with stock motor. with 440 kit should always run the 16-38

[ThorR88]

so i should carry one 15 and one 16 change it according to track?:blah:

[jasoncarr25]

yep.
