Dub..
The 140/330 and 65g BB weights is decent.
Do as boxer says... pull the spring and check it for breaks and proper free length (about 3.65"... but call Team for that spec if you want to be certain).
The next things are to re assemble the clutch without the spring and check for wobble and smooth action.
Make sure the side clearance is correct and that the belt is not too worn (compare it to a new belt). If the side clearance is not between .010 and .020"... have it shimmed and balanced by a good shop that knows what they are doing.
Set the Deflection (easy)
Wash the belt with a stiff scrub brush, super hot water and dish soap... rinse really well and let it dry overnight.
Pull the muffler, drain his Chaincase (be carefull not to cross thread the plug when re installing it... it will do this when you breathe on it the wrong way lol). Inspect the gears/chain carefully (remove them), clean out the residue, adjust the tension, install the cover and put in new synth oil. (Easiest to do before you put the cover back on if you have the sled on its side... just pour the correct amount [11oz] before installing the cover and brace. This is a good idea to do a couple of times a season if you ride a lot... great to do at the end of every season regardless.
