Leave it Stock!!!
Everyone knows I'm opinionated so here it goes again.
I ran against several geared down 1000s with the same setup as mine and not a single one performed as good. So if you think yours did like all the other guys out there your smoking crack.
This is why most guys think theres did, because by gearing down it compensated for the chitty as clutches and motor movement, so it actually did work better than before.
But when you compare it to stock geared 1000 with clutches that work and the right motor mounts the stock gears will walk away.
You guys can say what you want for 2 reason, I sold mine and don't care, the pc 800 will do more anyway.
and like always even the guys I stomped in the ground still thought it wasn't the gearing.
Fix the f ing clutches and get the right mounts to keep it from twisting.
If your stuck on gearing down, good for you.
But at least fix the problems first.
