TOM,s SNOWMOBILE "CLUTCH"Is It BS?
I had a conversation with Tom awhile back when he expressed his excitement about some new primary arms which he has designed.He indicated they will gain 10 mph track speed.Now 10 mph is alot!I have a mod 880 race motor in a fully moded XRS,156X2.5. and Thundershift clutch kit, I have 58 to 62 mph track speed at this time and holds 8250 on a climb.The weight distribution is throughout the arm and aprox 62 grams with oversized rollers.415,s,160/320 My delima is that I maintain hugh track speeds on a climb but I suffer on a flat full throttle run,Cannot get my setup to shift all the way out.This has been problem with SkiDoo,s primary. Either clutch for the hills or for the flats .When Tom told me about these I felt ."Why would he claim such an inprovement when he knows "I will find the truth and end results.I gave them a shot.Whats a few more bucks when I look at the overall investment in this sled..I really did not expect to see this gain above which I,ve seen with the Thundershift,s..We,ll these arms flat rip,My track speed is the same on a hill and this kit kept pulling super hard at near 80,Was still pulling hard but had to shut her down since snow conditions were poor.It pulled just as hard at 60 as it did at 35.I dont know yet where it will settle out at but have already seen about 12 to 15 mph over my old setup, Checked the marks on primary and its shifting out further than ever.3/8 inch from the top.These arms have a completly original profile not seen on OEM arms.How can this make such a change? Talk to Tom.He told me he,s been working on these and the results are Real!.Choose to be skeptic .Suit yourself. I not looking for an arguement so if you choose to disbelieve "Fine."And no I do not work for Tom ,Nor have I ever met him,However his dedication and love for the sport has enhanced my sleds performance and my enjoyment.
