Tav30 gearing question

[Razzar]

I have a 6.5 clone engine with 18 inch rear tires. I will be running a tav 30 and would like some input from people on what is the best gear set up for this. It will mostly be used on trails and off road. What size chain set up (35 or 40/41) and what would be a good sprocket size for the axle.

A top speed of 25 to 30 mph would be fine.

Thanks

1/2" pitch, axle sprocket 54-60 teeth, jackshaft sprocket 10t

I would say 60t MINIMUM, with such large tires, even a 6:1 is a little high, but should be ok with a torque converter.

Its going to 12:1 from the engine to the wheel when he starts out.

A 54 would be just fine.. it wont hurt the torque converter with 18" tires Krunch, 60 is standard though, I wouldnt want to go bigger.

Doesnt matter, 5.4:1 is still a bit high for off road, if your doing a lot of hill climbing and such your belts will wear much quicker.
