I think it's 17 on the front but i know its 42 on the back. It's the same gears i have run ran with this tranny for a yr and half with stock cylinders ported by a local guy and was running 7.0 no problems with 20 x 10 x 10 tires

I have got a Athena big bore kit ported by roger @ Wicked with a 1-5 override tranny. Just put the motor together and ran it last night and i ran out of gear about 3/4 track (1/8 mile asphalt). Anybody know what would be a good sprocket size to run?

could a bad exhaust seal cause it?

I got a buddy that's gonna let me try his cdi in the next day r so. I had a ricky stator last time just something came loss and messed it up so thats what i went back with it over the ebay stuff

It wasnt on the intake side. I'll have to get a leak tester for the cylinder side tomorrow

177 and im not sure how to check for air leaks

It checked good

Keihn carbs. Brand new Ricky stator stator and new flywheel

I swapped the carbs from left to right and it stayed on the left side

I have just put a Athena big bore kit on with 1/8 mile drag port on. When I'm going above half throttle the left cylinder sounds like it stops firing it kind of sounds like its a rev limit but it only does it on the left side. I have swapped the carbs, reeds, and plug wires from side to side. I also have a dyna fs cdi box. Any ideas on what is going on?
