Low Elevation clutching

I ran my 2011 X-Fire in WY. this year and followed what it said under hood and ran spot on. Was pulling 7900 rpms all day. From the factory it was set for 0-3,000. For over 9,000+ it said to run 58gram weights and a 36 degree helix. I would follow what it says under the hood and will perform spot on.

75g work well 0-4k running a blk speedwerx primary spring revs 8200 and still pulling hard

weights low alt

2012 pc 162 2000ft ,won't pull it .this is what i've tried so far new-0miles 75g 42-40 helix low alt kit ,pull 8100 flats, 7800-7900 in climb lame 50 miles 70g 36 helix pulled 8150-8200 flats, 8000-8100in climb, better but felt like a weak sewing machine. 100miles went back to 42-40 helix and 73g good bottom end lacked top again. 150-200 miles running 73g 42-40 helix, 2010 orange spring in secondary pulls up to 8150 then drops back to 8000,getting closer , haven't done so much clutching since 800 mc,not real pleased with it. snow has been good so haven't messed with it lately . so to sum it up 200 miles so far on 2012 and 800 miles on 2010 turbo .

I only have 70 miles on my 12 PC 800 153 and ride in 2500 elev im using MDS weights about 85g. I called Steve what the best setup would be and thats what he recommended. I also use the Cat red spring. These are awesome weights, pulling 8150 at top end. They make a huge difference in every area, take off, midrange, and have excellent backshift. I did run factory stuff before i changed this so i can tell there is a world of difference.

2012 800 hcr.mds 83.5 gr,cat red,team tied on the 57 side red blue spring.sled works well in every situation except above 3500ft. falls off fast after that.
