That's what I was thinking of doing next season, 1 tooth smaller on the top, fairly cheep to try and extend belt life. The hardest rider in the group has not got over 560km on a belt. All sleds are 165 x 3" tracks
All sleds use the factory belts, and the belts look good, that have a green color, so not like there slipping. They just get small cracks on them, where they touch the clutch shives.
And we have a few stock doo low elevation clutched sleds . 1 ibackshift kit, 1 riderz full kit, 1 with the stock setup and a 150-300 primary sprig. And all about the same belt life
Iv gone through 4 belts on my gen5 turbo, all under 800 km.. so has my riding buddies. 5 gen5 turbos in the group and no one can get over 1000km. 650-700km seams to be the time to change the belt before it blows up.. I clean my belt and clutches every 2-3 rides. Makes no difference.
Its not a finished picture, there will be frogskinz covering the holes, and you remove the sock frogskinz and the ibexx part slides inside the air box an gets attached. There working on the right side also.
We have welded 2 or 3g nut on the bottom of the stock weights. Still pulls 8400-8500 at 2000-4000'. This also pulls much better track speed over stock in the 48-50mph. I have tried epi 76g actual weight is 77.5g and they have much better bottom and mid range, still can't match the top end of...
