G2 Secondary Belt Clutch Adjustment

[Shepard]

Does anyone have printed information on how to use the spring hole settings in the stock clutch? What is the factory setting - what individual settings produce what type results. I know people have personally experimented - what chart have you worked from?

In my factory yamaha manual for the G14-16 carts they recommend B-3 on both. I then used B-1 with the Umaxx spring with the stock engine and now B-1 with my modded 460 with a stock spring.

I'm using B3 now - I'm cruising at 35 mph on flat road - as I go up a steep hill the engine rpm stays the same 3600 rpm and the speed goes down to 25 mph till I get up the hill -- then it speeds back up to 35 mph and the engine rpm never changes 3600 rpm. I'm looking for a new belt. I wouldn't mind spending a 100 dollar but find what I want is a pain.

I am running the Dayco XTX 2264 which is an 1.26 X 42.83 " belt and I set it up with very little deflection. It is a little reluctant when shifting F/R when dead cold. The upside is I picked up about 4 mph at a given rpm. I don't know if you use the same belt length need as I do. The belt was something like $80

As you run the letters, numbers higher it has more tension which makes it not lower rpm when light throttle. Its nicer for trails but not nice for cruising. I ran a setting higher for trails and stock otherwise. If you mark the sheaves and set the spring in the different number/letter combo you will see it just indexes it a little more as you move up. So assembled it has a little more preload pressure. If you set it really tight it will stay at max rpm all the time. You set it loose it will drop a lot of rpm at light throttle and be slower to rev to max rpm on the floor but still will rev up.

The best belt I ran was the CPP kevlar, an erlandson I think. Top and bottom cogged its pretty flexible. They list HD belts now but I don't see kevlar listed? It was stock G9 size however I think it was a 1.25 wide. I had to move my engine and go to a polaris scrambler belt. I got a cogged one but its not as nice as that one, think its a dayco I'd have to look. It works ok.

If you have a larger engine usually the stock setting works fine as it has more torque. Stock engine you are trying to get all you can then a higher setting helps a little, on a lifted big tire cart or with HS gears, but go stock on a stock tire cart unless you are towing heavy things.

The gboost kevlar is what my belt is.
