For the record and anyone who cares.
Thanks to everyone who contributed past advice on here and Hard Core Sledder.
Time and money were more limited than normal this year. I did a budget temporary setup. Budget as in I found used components where possible and went with the minimum number of parts to get a workable setup.
Another side note: The winter where I am this year has been slightly better than junk. I have yet to ride my sled at below freezing temperatures.
Top speeds are in a field with limited space in packed but sloppy snow.
-220 pounds with gear.
-126 woodys recommended studs. 3 in the middle of each bar.
-My suspension setup is for max comfort on bumps, jumps, stumps, ruts and wrecked un groomed trails with endless satanic moguls. No compromise made for speed, slight compromise made for handling.
STOCK
Belt:
Stock and modified, I tried Gates and Polaris belt, soap and water cleaned. Gates belt worked the best for me in both cases. I never measured them.
Stock Observations:
-Highest top speedo speed recorded was 92mph on multiple runs. Above freezing, packed but sloppy snow. Sometimes only 89mph
-RPM 7700 to 8000. Inconsistent.
-Belt only climbing just past half way
-Evidence of belt slipping in all ranges.
-Sheaves too hot to hold
-Boggy in midrange sometimes
-In slow tight hilly woods riding, it would feel like the belt was slipping and the engine was boggy.
-Belt would sink down in secondary during reverse sometimes.
Detail Fixes:
-Track adjusted per Brock specs
-Secondary floated to Brock spec
-Chain tension on the loose side of spec (stock it was okay)
-Exhaust removed and sealed with RTV
-Front end alignement checked (was good)
-Clutches scotchbrite de glazed, soap cleaned and checked for assembly and cleanliness.
-Delrin washers in secondary.
Modified Setup:
-1.74 gearing. 23 top, 40 bottom 70 pitch hyvo chain. Stock top gear, bottom gear and chain we're used on ebay.
-10/70 polaris weights. Used. (I bought others new but screwed up and bought ones without bushings by mistake).
-155/222 secondary spring. Stock helix. Spring is on heavy side. But works with stock helix and warm sloppy snow.
Results:
-Highest top speedo speed 103 mph in same field, 2 separate days, multi run, above freezing, packed but sloppy snow. Always 103 in same distance.
-Rpm always 8200-8250
-Always ready feeling midrange.
-Belt climing much further toward the top.
-Clutch faces normal warm and can be held indefinitely.
-No evidence of belt slip
-Sled always snappy and ready in slow woods even with passenger.
-No belt pull down in reverse
If the sled came this way I would be happy. It's faster than my friends 2015 Etec 800 in all cases and feels much more punchy all over.
But....
Next year I will try Dr, and Brocks recommended helix and the 140/200 secondary spring. I also plan on getting the primary worked over per Dr, Brocks and others recomendations. I will also do TPS check and if I have the money a power commander. On warm days you can tell the sled is needlessly rich.
