My 670HO just doesn't go as good as it should. I am trying to figure out what to do to make it pull harder. My current clutch set up is as follows: stock arms, stock 16.4 gram pins, 280 ramps, 230/320 (pink/purple) spring, stock 53/47 helix w/ 19 lbs of preload, Goodwin teflon buttons. This is very similar to a set up that I ran on a 97 mxz 670 but it pulled much harder on that sled. I am considering going to 18.5 gram weights from Fast but I don't understand why I should have to run that much weight with the above set up. Any help would be appreciated. I don't like getting beat by my old 97 MXZ670 that now belongs to a friend.
I tried the 280 's and found that the combination of the ramp profile and the 53 deg helix were too much for the sled to pull with stock gearing out of the hole. Try a 24 tooth top gear with a straight 50. That works much better.
I have an early 1970s Bombardier Ski-Doo single cylinder. I need to lower the primary clutch engagement rpm. What spring and weights would make it possible to lower the engagement of the primary clutch. Thanks for any knowledge you can send my way... Chevysteve.
I wasn't interested in a new sled. Was satisfied with my 16 4-Tech 1200 Renegade and my 17 900 ACE Renegade. Dealer talked me into trying his personnal 19 900T Renegade with a chip and reflash. Claims it puts out 190 hp.
Besides being quick,and fast it doesn't lag and handled well. So I...
Hello
My snowmobile is skidoo Formula MX XTC, model year 1995. My skidoo front light work poorly (only 3 volts given) and i was wondering where is the battery located? Or does this skidoo have battery at all? Engine is rotax 467. Anyway there is something wrong with electrics.
I ride a 2001 ski doo touring 500fan, and over the past year have spent a lot of time fixing issues with it (it was sitting unprotected in a backyard for 5 years). I cleaned the carbs, fixed some electrical contact issues, and redid much of the fuel system. It used to bog down when I went past...

Can my rotor be warped causing this brake up?
Thanks in advance
