I have a question regarding my 440 MXZX. I was testing it on the lake the other day and noticed the motor was pulsating at around 8300-8600 rpms. If I backed off the throttle, it would actually pull a bit more than WO. It almost acts as though there is a rev limiter but it doesn't seem so pronounced. My top speed was 73 on the GPS.
I did a plug check and found that they were running good. (switched plugs also) Fuel looked good. Adjusted the floats just to make sure. Stock jetting running in 40 degree temps.
My clutches were all cleaned prior to testing. My secondary was shifting out but my primary was about 1.25-1.5 inches from full shift. I am running 293x ramps, 250-380 spring, tested with several weights from 10.7 gram pins to 16.3 gram pins. Secondary running Dalton 44-40, Beige spring, B-6. I also ran 296 ramps with 10 gram pins and 230-350 primary with similar secondary settings with same results.
Usually the problem you describe is an indication of the main jet being to rich. It can also be caused by a main jet being to lean, if you have run long distances and not burned down than you should check for being to rich.
The 98 zx`s had a problem with a slight intake leak around the reeds that would give you the same symptoms,theres a red non drying permatex type sealer that should be used in that area.
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
