Same, mines a late build as well and it’s been running great, about 30-35hrs and 300 miles now. I tried the Ibexx clutch kit i had ordered on their Black Friday sale. It killed track speed vs stock. Wouldn’t even hardly pull the skis up anymore. Kept the slightly stiffer springs from the kit but put the stock weights and helix back in and she came back to life, back to wheelying up everything and she’s a 165”. Haven’t had heat issues on mine as long as I run the scratchers down in low snow, but also haven’t had it out in super frozen/crusty spring conditions yet. Also, I see people wigging out about how little oil these use, but mine uses probably double the oil that my ‘20 ascender used, even with a tune on that sled that supposedly increased oil useage. My 858 uses enough oil that it leaves a black spot in the snow if I stop and let it idle in one spot for a bit. Definitely not upset about that. Aside from a ski shock failure, mines been great overall and I’m loving this chassis now that I’ve figured out how she likes to be ridden.
