Comet TAV2 Belt life expectancy.

Gidday.
I was wondering if anyone out there is running this combo- 13hp honda clone, tav2 (GTC not Comet) with 10/60 sprocket combo, 22inch knobbys, oddysee style dirt buggy so fairly heavy. On the road my GPS says its doing 63km/h (39mph) on the rev limiter (approx 3600rpm). Problem is that it is killing belts at a rate of 2 tanks of fuel/belt. I have checked and rechecked all aspects of the CVT and its all running true in regard to allignment, bearing wear etc etc, so I think its a problem of too much torque and too much weight. I think I will get an Azusa 80 tooth rear sprocket which should lower the top speed, but take some load off the CVT. I got my son to drive flat out on our property and found that he only got to 43km/hr (26mph) and an 80 tooth shound give me about 49km/hr (30mp/h). I weigh 95kg and my son weighs 40kg and I have noticed that when Its my go to drive the belt seems to suffer much more!! Today I swapped front tyres for rear 22" on front and 19" on back and although it looked stupid the CVT seemed much happier.
Any experience and advice with this would be appreciated. Cheers.

I don't think that the GTC Tav2 can handle 13hp or the weight that you are attempting to pull. They rate it at 13hp, but the Comet design that they copied never specified it taking anything over 8hp...

BTW, how much does your kart weigh? I know Odysseys are quite heavy. Those speeds seem too slow. I do about 55 mph with my setup of a Subie 9 hp, 9 tooth front, 54 tooth rear, 18" tires, and GTC Tav2 30-100.

Currently, I am still battling with the belt issue too. New belts are awesome, and then slowly the TC will not shift into overdrive. I get about 2 hours per belt. I do have a slight alignment issue with my GTC that I plan to fix. The motor is hitting the jackshaft from the rear and slightly bent the mounting plate of the TC. Very slightly, but I am going to space it out more to eliminate that bend because I keep reading how important it is the both pulley's shafts are parallel.

You will need a Comet 40/44 series for that motor. No GTC or Comet 20/30/tav will handle that kinda power.
