You must have a good size wallet. With that engine you would move up to the series 40 T/C . You would get rid of the band brake and switch to a mechanical disk brake. You will have to build your own jackshaft arrangement with the series 40 but that is no big deal but use a 3/4" jackshaft (avoid the 5/8" with tires as big as you have you would bend the jackshaft when you brake hard). Go with a 10 tooth #40 sprocket on your 3/4" jackshaft going down to 66 tooth axle sprocket. You can get the sprockets and the carrier from Azusa in CA. They make a lot of the things themselves and they did supply many of the backyard fun kart manufacturers. BMI is another good source, they bought up much of the stock of the fun kart manufactures when they closed their doors in 2005. Lot of good companies out there so ask them what they would recommend. I sure as hell don't know it all, if I did I would have run for President.
I recently fixed the T/C by adding a washer to the driven, but i don't know if its cause it doesn't have a belt (currently waiting on one) when i turned it on it started going crazy as if i was throttling it (i do have a video i could email you). also if you don't mind could you also give me a brief explanation of offroad go kart ratios.

If you can get the driver and driven lined up straight, get a 8t sprocket for the jackshaft, get some 3100 rpm engagement springs for the driver, it will most definitely allow the belt to last longer.

ITS NOT GONNA BE THE OPTIMAL GEAR RATIO for those 22" tires and the weakest 212 to date, but will be sooooooo much better for off roading.

As @JimD mentioned about the jackshaft, try to avoid heavy braking. Not only the small 5/8" jackshaft being weak, that t/c plate will be flexing alot under hard braking.

It really needs a solid 3/4" jackshaft, better bearings with solid supports to keep everything nice and straight at all times.

I would try it with the parts I mentioned, with a cheapo belt 1st. Jus to see how long it will last, .....i mean c'mon, what do you have to lose??? Maybe $50 ????

I've decided that i am going to let it rest until i can get the new motor and new axle because whats the fun if its just gonna break every 2 days also it gives me time to paint the whole go kart agian.
