In clutch setups I was looking at srx_eh's setup. Seems to me its a G-P-G primary spring it calls for, is that the stock primary spring? Also for ex(4.5) first hole, just getting into sledding and no clue what that 4.5 means and it calls for 1 engagment shim, it engages at 4100 RPM and peaks at 8000 and is using stock weights, they also talk about the helix position which is 45/41 (dont know what that is either) and a 70 degree spring setting (no clue either) Please help and tell me if this is a good setup.

Check in the tech section under stock snowmobile specs and you'll find your sled and it says the stock spring. Some weights have holes in them to add or remove adjustment rivets. One hole in the middle and one in the tip. For example a 4.5 is a 4.5 gram rivet. An adjustment shim is when you put a washer under the primary spring which should raise your engagement a bit. 45/41 is the ramp angle on a multi angle helix. The angle start s at 45° and works its way to 41° as it shifts out. The spring setting or WRAP is where you have the spring set in the secondary. You'll see the numbered holes on your helix and there is three more in the clutch sheave. So 70 should be in the #1 hole in the sheave and #6 hole in the helix. 6+1=7 or 70 wrap.
