800 drive sysetm on 04 600,??

hi im new to snow hawks, ive got a 04 600 136 that has thrown its belt a few times now,so bad on the jackshaft that the belt has cut into my belly pan.ive seen the chain drive upgrades made by the varoius talented folks on this forum and i will be looking to preform that upgrade when erxta$$$ come my way.. in the mean time i have access to a brand new complete belt system off a 08 800.what im wondering is has anyone done this...will it effect my gearing in a negitive way. any insite would be greatly appreciated...

thanks for the imput, the belt on the tls cut my belly pan on my 1st ride.so at that time i disasmbled the whole set up and i did reinstall as per the manual. on my next ride the belt slipped off the drive sprocket.the drive sprocket on my 600 is a 28 tooth and my tls is a 56 tooth. im not shure what model of 800 the possible donor set up is but io think its an enduro,the tls is the same 56 tooth but the drive sproket is a 30 2 teeth bigger. will 2 teeth in the drive sprocket make much of a diffrence. most of my hawk riding will be done in power lines and foot hills type of terrain,when it comes to mountain riding i generally ride my 2 ski(sorry for the dirty word). so would the 2 tooth diffrence make my hawk un ridable or would i just ge a bit less bottom.mabey i should wait till i can get the upgrades??
