Tech FAQ Area!!!

It's apparent no one at the proper forum is able to give sound advice/diagnostics and that's why i came to the real professionals.

How often are crank seals changed on sxr700? Do they fail all at once? Sled ran fine 1st time out only every since it cuts out at 6000 rpm or higher when warmed up. Is this possibly a crank seal?
 
FOUND PROBLEM. Fuel screen in all carbs under needle valve plugged. didn't allow full flow at high rpm.

Thanks all for the assistance.
 
Darting Vmax 500

There is some really great info on this site! Thank you for all the work you guys do!! I have a 94 Vmax that darts pretty bad and I read the specs and technical info on the page but does the spacer go toward the front or the rear of the ski?

Are you talking the ski shim mod? or???
 
That mod is not really for/affective on the older VM's like yours just the newer Proaction chasses.

try adjusting your skis with a little "toe out" adjustment should help.

Welcome to a great sport and a great site!!!

A few initial recommendations come to mind . . .
  1. Go to www.yamaha-motor.com and dowload a copy of the Owner Manual for you model. Read it completely and you will get some useful basic information.
  2. Whenever you have specific questions, use the Search feature on here as there are a boatload of old threads that can help you.
  3. Learn about what is in the Tech Pages on this site. Lots of good info.
  4. For questions like these it is usually a good idea to start a new thread - look for a posting guidelines thread.
Now for your current questions

Yes, 2 strokes smoke, especially when the weather is warmer and when they intially start up. Sleds are jetted for cold temps (denser air)

Be sure to check your oil level in the oil tank - it may simply need to be refilled. You will have to add oil every time you refuel or at least every other time.

Happy Reading !!!

How do I raise the front of my 97 sx 700 triple to get higher than it is stock. I bought a sled with the rear brought up but the front plows pretty badly. I have kyb shocks in the front and it rakes like a muscle car. Pretty much sucks. What are my options to
Raise this thing to not plow?
