gearing with 20" tires

[BKex]

Im wodering what front sprocket I should run with the stock 38 sprocket in the rear with 20" tires?

Or what size sprockets would be good for the front and rear.
I pretty much ride trails and will line it up and race the guys. Normal mods on it pipe/filter.

Thanks

Probably a 13 with the unported cylinder. You could get the head cut & bump up the compression & run race gas & could probably pull a 13/36 or a 14/38.
If you was to have one of my ported 350 top ends sitting on the cases you could probably pull a 14/36 & leave the light in 3rd gear, but be ready when you hit 4th cause the front ends comming up.

Thanks Neil ill probably go with a 13/38, and i wish i could have the power of a 350 but id probably kill myself . I already keep the front wheels off the ground enough....had a bad wreck in 5th doing a wheelie on pavement and that did not turn out to good. Bent sub-frame, axle, stem, wheels, and 13 stictches in my hand and the road rash:scary:

For some reason mine has 12, 38 gearing. Feels great with MX tires.
