I noticed today while riding on one of my twin VMax's when I take off from a stop the clutch seems to kick in all of a sudden.. It's not as smooth takeing off out of the whole as my other VMax. After I get going it seems to be fine riding around.

Should I plan on rebuilding the primary ? The belt is a Xtreme Gates that is sitting just above the sheaves on the secondary.
 
The twins were really hard on roller bushings. Check them for wear. If there is play side to side replace em.

Check your belt deflection,it may be too loose or your belt
is wore out(to thin)..

My belt is new.. it's a Gates Extreme. It sits above the secondary just under an 1/8 in. I believe that's what Yamy recommends isn't it? But I will add washers to get it flush or just below top of secondary sheave..
Thanks again

In your original posts you said it was one of your twin vmax,s. That,s confusing info.

On that sled you need to be 1.5mm above to .5mm below the edge
of the secondary sheave, with a new belt..
 
The manual calls for 2mm or .08" below the top of the secondary. Anywhere between -2mm and the top is ok.

Something is certainly worn. Have you serviced the clutches? What is the mileage on it? Not knocking Gates but I'd stick with the Yamaha branded belt for your sleds.

If it were my sled I'd start with inspecting the rollers for wear. Then the weights "ramp" surface for anything that looks odd. Then move on to the bushing. Change the spring to a new one if you have more than 1000 miles or 2 years on it. Look at the secondary. The "Pucks" that ride on the helix can wear as well. And the same goes for the secondary spring.

Clutches have never been serviced..I have 1500mi. on them. I'll double check to see if the belt is set right. I'll get back if it is and it still does it.

Thanks
 
My 95 did the same thing just before an arm broke off the spyder. I would check the cap and sliding sheave bushings before bad things happen. Mine was also eating up the roller bushings before this happend. You may want to pick up the primary rebuild kit instead of buying seperate parts.

I did change the belt to a new Yamy one and it did the same thing so..

What did the roller bushings look like? What do I look for on them for wear factors in need of replacement?

Were do you recommend I get a rebuild kit from? Yamaha? I have no problems with rebuilding it myself as there is lot's of info here on it.

The rollers should all spin freely with little or no play. My sled was wearing out a roller bushing every 80 miles or so. The bad rollers would also start to eat into the weights. It's very easy to remove the rollers and check the bushings. A good sign of worn bushings are flat spots on the roller itself. Yamaha sells a clutch kit with everything you need. I think they are around $120.00. You do have to remove the spyder to change the sliding sheave bushing. If you remove the cap and spring(Very easy) you will be able to tell if the sliding sheave bushing is worn. I just wish I new all this before the spyder on mine broke!!!
