clutch work

[Glenn]

When do you know you have to get clutch look at.I have 3500 miles on my 2006 RS It runs great but I was wonderring about when should I get my clutch rebuilt.Any tips would be appreciated

If the sled is running fine I would wait until the sled won't shift up any more and you notice a reduction in fuel mileage.

Just my opinion, you are good for another 3,500 miles.

Hope this helps!

I kinda disagree hondo. The average rider won't notice the upshift change, because it's a gradual thing. They will notice the MPG drop however. I will never again assume that I'm good for another "X" amount of miles.

It's REAL easy to pull the primary clutch cover, take off the weights and rollers and inspect them. If you see any flat spots on the weights, put in new weights and rollers. People have suggested and I find it to be a good idea to change the primary and secondary springs on a yearly basis....cheap insurance.

If you don't want to take the primary cover off and do the inspection, or change the springs, let your dealer do it.

Take them off every year and clean them up , look for any type of wear, if all looks good put it back on and ride...........

My primary needed work at 2500miles, the secondary is also pitted.
No warranty! I have 100 000kms experience on snowmobiles, and have never had to work on a clutch, before the 4-stroke Yamaha.

I take an air hose and blow out the belt dust, as often as I can. Seems to help.

Yamaha's 2-strokes were excellent. I'm so disappointed with whats wearing on my new 4-stroke, and nothing being covered by Yamaha, that I probably won't be buying another one. This weekend, it started running like crap again. Same symptoms as 2 weeks ago. You have to give it gas to start it, and when you come to a stop, if you're not giving it a bit of gas, it'll probably stall. This is with the engine already warm. The carbs were sync'd 2 weeks ago.

Roger, you might want to pull the bottom float bowls off of your carbs and take out the pilot jets and make sure they are not gummed up. It isn't a hard job at all. Just gotta pull the airbox, and loosen the carb flange clamps to pull all 3 carbs out at the same time. Then you can get to the jets. Or try some good fuel injection cleaner through a tank of fuel. Just one more reason why Yammi should add fuel injection to this engine.

What happened to your clutch after only 2500 miles? Weights worn out?

Roger - try a full can of Seafoam in a tank of gas.

Cat - did you change you mains or pilots? My engine (05) is jetted fat for sure....I'd lower the needles but you can't on these Keihn's. I think I'm OK in the pilots, but I think I could lean the mains out a bit.

Someone does sell a jet kit for these sleds, but I can't remember who. I haven't messed around with the jetting at all. I took out the pilot jets last fall because I was curious to see how they looked. The pilot jets are so small that any amount of varnish or gum will render them useless. I don't plan on messing with the carbs at all, but I will sync them before next winter.

Sorry you feel that way. I have owned Yamahas since 1979 and have had pretty good luck with them. I really like the 4-stroke, and have had next to no problems. I have always blown the belt dust out on all my sleds, and have had very little wear. This sled has close to 9,000 miles and I am seeing some wear on the faces of the sheaves. They are not bad enough to think about changing. However, I will keep checking them.

Will the carb cleaner damage anything if I put some in there right now, let it sit there and idle for 10 minutes, and then let it sit in the carbs until the weekend?

The clutch had Comp rollers, RS slider kit, and 8BV washer plates replaced.

Thanks for any info.

Will the Seafoam, or carb cleaner hurt if it sat in the carbs for a few days until the sled was really used?

Thanks for the info.

How do you sync them?

I still have my 2001 700 Venture. 20 000kms on it and the engine still works great. I had to reweld a bunch of rear suspension parts that broke due to fatigue, other than that, nothing. I oiled its clutches every time I used it, and still no problems. Would oil not do wonders for these clutches also?
