I have a stock 1991 mach 1 with a 617 rotax and ive been reading alot about people its good to make sure you dial in your clutch. also read a thread about best mods and next to studs was clutching.
Im confused, what does this do, i mean whats wrong with my clutching now? how come its a good mod? and how does a person know if they need to do it? if they do need to do it, how do they do it?
lots of questions i know but you guys just know so #### much about this stuff, its hard to not ask
Well, "dialing in" your clutching basically allows your engine to use its power more efficiently for your needs. With a CVT (Continuosly Variable Transmission) like in a snowmobile, you can change the way the engine shifts by manipulating several components in your clutch system. For example you can make it upshift very quickly, which gives you faster acceleration and top speed, but sacrifices downshifting, or your sleds ability to keep the drive belt in the power band corresponding to the rpm of the engine. On the other hand, you can increase the downshifting characteristics which will give you better throttle control of power, but sacrificing top speed.
Clutching is basically the search for the perfect balance between upshift and downshift. Stock sleds come clutched reasonable well in most cases. However you can use clutch tuning to make your engine behave better in a certain situation (ie: drag race vs. powder vs. trail riding)
Hope that makes a little sense...this is just what I've picked up from the real clutch wizards on this board. I'm sure I have something backwards in there, and I'm sure it will be corrected and wrists will be slapped...
ok cool thanks rocketman, so would a drag racer have his clutch set up so he has terrible downshifting? whereas a person that races on a short track would want to use more downshifting then topend?
i think i understand, and i thin ill just keep my hands off my clutch =).
It's not that tough zagg. We can get you through it. Just need to know what is happening now, how you ride, where you ride, how you want it to act, and how much you want to spend. Do you or one of your buddies have the right tools? Are you new to the sport or are you just getting into upgrading performance? Let us know. You'll get a lot of help here from the guys.
well theres nothing wrong with mine i dont think, it really moves like a bat out of #### for me =).
I decided im goin gto just keep it like it is, and read all the other posts about it and see what i can come up with. If for some reason mother nature has some compassion for us, i dont what to have a goofed up sled. I faith that day will come
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...
First time for the season the brakes lockup and got hot. and continued to do it all day. So replaced the caliper and dot 4 brake fluid cleaned reservoir and tried brakes seemed to work fine. Go out again brake lockup.
Can my rotor be warped causing this brake up?
Thanks in advance
