I am working on a 2001 mxz 600. I need it to beat a 2002 ZR 600. Right now both are stock. The MXZ get the jump out of the hole, but in mid-range (60-70) the ZR catches the MXZ and then walks by. I don't want to gear or do clutch work for top end that will hurt low end bad, as most of the places we ride you don't see top end anyway. I was thinking of gearing down a bit and playing with the clutches. If we can get another couple sled lengths out of the hole, the ZR won't touch it. Any suggestios as to what I can do for gears (if I should at all) and what I can do as far as clutching?? Any help would be appreciated. We can't let the cat win!!
It is so unfortunate that that stock Cat is beating you.
You could try a multiple angle helix in your secondary. You will have to choose the one yourself though.
multiple angle helixes help you put your RPM's where you need them.
Make sure your throttle is fully opened, mine was not. Align clutches, shim secondary so belt almost stays engaged, this is better than gearing down. Do not gear down! Clean your Rave valves, index spark plugs, jet down to conditions. What is your rpm at 60mph. Realign ski's, dealers don't try very hard. Advance your timing to #2 at dealer on computer, this advances, thenuse 90 octane fuel. Type of track and tension could slow you down.
Sharkey -- Thanks for the advice. This is actually a friends machine, so I am not sure what the rpms are at 60, but I will fond out. What should they be at? I will try the other things you mentioned. Thanks again.
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
