Clutching and Fuel 2012 PRO

[sled78]

Looking for some answers and suggestions here guys...just put 13.1 heads in (Power Addiction) and HPS can, now should i be running some AV/C12 Gas or 91 Premium or a combination of the 2, I ride a bit in the Red Deer area and the rest of the time in the MTNS, I've heard of guys slapping this system in and go, and I've also heard of guys needing to add 2 grams of weight to their clutch...definate answers are needed! Thanks in advance!

91 premium with no ethanol.

Just 91 premium w/no ethanol as stated above as long as you're over 3000'. I use mds weights with an extra 2g in them and a 100/340 polaris primary spring.

On my 2012 800 163" I went from stock 62gr to 64gr. Worked perfect, but when I went up to 7000ft it was a bit too much weight. I bought some SLP MTX Weights so I can get her bang on.

I haven't use the sled around here, just mountains. I run a 13-1 as well with 91 octane.

SLP weights worked great on mine. Load up the bases as these engines really seem to like the heavy heel weight. Running Carl's helix, SLP gold secondary spring with delrins, SLP blue/pink primary and the slp weights loaded up in the base, and using the EPI belly busters at elevation, added 2 grams with a steeper helix and pulling right at 8050 all day and clutches stay cool.
