  1. Switchback/SKS/RMK
    I have a 2003 RMK 800 but the previous owner swapped a 700 and im not sure of the year of the engine but it is a non-power valve engine but when you pin it it takes off and then around 6000 rpm it bogs and acts like it’s hitting a rev limiter for about two seconds, and then takes off no problem...
  2. Matryx Platform (Indy VR1/Launch Edition/SBA 146)
    Hi guys, took my '22 VR1 in this morning to get the primary recall done. When I picked it up they had the old clutch cover on the service desk with a note from the tech (picture attached) I'm running an OutCast racing clutch kit with a different primary spring, weights, delrin washer... The...
  3. Yamaha General Discussion
    Hey everyone, I have a 2000 Phazer 500 with an on ongoing issue. The machine starts and runs great but will not go over 40 MPH and does not get full RPM. When jacking the rear end up it reaches max RPM and 85ish MPH. The carbs have been cleaned and readjusted, new spark plugs, fresh gas and a...

    Any folks that balance/rebuild clutches in the Dane county wisconsin area ?
  5. Specialty Sleds
    I hope I'm in the right area to post this ... I have a 1975 Sno-Jet 440FA with the Arctic hex drive clutch and original driven clutch. When the driven clutch engages, the power cuts out and the sled won't exceed 40 mph. I've swapped out the springs on the drive clutch, changed the scatter plate...
  6. Polaris General Discussion
    I'm replacing my belt on my 1994 Polaris Indy XCR 440 XP. I got the old one off and the new one on with no issues. I'm now trying to dial in the deflection. Every video I've watched on YouTube (except 1) is showing a secondary clutch that takes a tool and you screw in or out to adjust, making...
  7. ZR/ZL forum
    Hey all, just got an ultra clean 2000 ZR600 carb (non ap) and after not being able to outrun a ZL500 I'm looking at messing with the clutching. It takes off quite late (maybe 4500) and seems to struggle to get the power down. I came from an Indy 500 89 and that almost felt quicke, somehow. I do...
  8. Trail/Classic/XLT
    Hello all, i am new here...... but i was hoping someone that has run into a similar problem in the past could help me out here or point me in the right direction. I recently replaced crank seals and put the engine back in the sled and got everything back together and got it fired up. Only to...
  9. 440/race/modified
    I’m getting a iqr 440 extended to 155 and it has a Polaris rmk 800 2003 motor with twin pipes and stingers and mikuni flat side 44 carbs and the clutch bed tuning so I am wondering what weights I need to run at 1000-3000 feet
  10. General Snowmobile Forum
    I've been having some trouble with my 1997 Indy 500 SKS lately and I've finally got the idle perfected and the secondary clutch adjusted properly. When first driving the sled it will go about 20 mph at full throttle with RPM very high then once I slow down it won't move anymore. I took off...
  11. General Snowmobile Forum
    i got a 95 500 and want to know what i can do for the clutch so i can pick up speed in deeper drifts, i haven't looked at the clutch yet to see if its in good condition or what the stock weights and ratio is, but it does run good and pick up speed after you get over the bog i wanna get rid of...
  12. Arctic Cat General Discussion
    I put 110 miles on my new to me 09' CFR800 this past weekend. Towards the end of the day I felt the clutch ( I think it would be the primary).. It was hanging up during decel from 5000 rpm down to idle. The could feel the sled shudder slightly as the clutch was releasing. This sled has 5000...
  13. Phazer
    Just purchased a used 07’ Phazer with 3000km on it. Ran fine the first rip behind my house. For some reason now it’s very slow to accelerate maxes out at around 7600rpm. I’ve swapped out the primary and secondary separately, adjusted chain and track tension. Sled revs up fine on the stand...
  14. General Snowmobile Forum
    Bit of a long shot and I don't even know if this is the place to be doing this, but I'm on the hunt for either a paperback version or PDF/eBook of the Olav Aaen carb and clutch tuning handbooks. They're no longer in print and I cant seem to find any copies for sale anywhere. tia :)
  15. Sidewinder
    Anybody have luck running the Polaris clutch weights in sidewinder
  16. General Snowmobile Forum
    I have a 1998 Polaris indy 500 that seems to run great until it gets warmed up. Once warm the sled starts to not rev up all the way and will max out around 45mph. If I give it wide open throttle from a parked position it seems to be fine and get up to normal speeds but if I am going say 25mph...
  17. XC
