My 02 Prarie 650 has a noise that I dont know if it is normal? I never noticed it before so I think its new. When you give it some throttle at low speeds, and high I assume, ( I cant here as good at high speeds) and let off the throttle, there is a noise that sounds like something is loose, there is no hesitation, but its like the quad is rolling faster than the gear, then when you give it some gas it catches up, and there is the noise. Its not a clunk, its like something is shifting back and forth. The tranny seems fine there is no slipping, it climbs fine, it pulls a trailer ok, and from a stand still it still takes off like a cannon with the wheels spinning. It sounds like it needs an adjustment, It may have nothing even to do with the tranny. I have no idea??????????Any input would be greatly appriciated

 

I have an 06 BF 650 with 8 hours on the engine, and it has done this clicking noise when I let off the throttle and coast and then again when I give it throttle. I don't think it is anything of consequence. Lots of moving parts, probably normal. My machine takes off like a rocket, the belt is good, and runs like a raped ape!

Bubba!

 

Its not a clicking noise, its like something is rolling around

 

Hmmmm, haven't had that happen but sounds like you might want to check the belt adjustment and the sheeves. Could also be something in the engine brakeing system.

 

does it sound like loose tires spinning wet pavement? sounds like to me the beering in the enginebrake. sometimes all it needs is a little cleaning

 

no it sounds like a little hesitation till the transmition catces up to the speed of the wheeler

 

Sounds like the shifter needs to be adjusted as not all the way seated in low range. Sounds like yours is just a like bit out of adjustment. If you go down a hill in low and it sounds like there are parts falling out the back end, then it is really out of adjustment.

It is a sensitive adjustment because too far one way and it will not go into reverse and too much the other and it does not seat in low gear. I have had to adjust mine twice and it was just trial and error. The next time my dealer adjusted (for free) and he got it right just letting it idle in gear. Bascially you have to loosen the nuts on either end of the shaft and then adjust the shaft into the correct position and then tighten the nuts back up. If you have good fingers you can adjust without taking the plastic off. Just watch your knuckles.

On the side note. My dealer adjusted mine for free when I had the bike in for the steering knuckles recall. He also noticed that my front brake pads were worn and replaced them for just the cost of parts. No labor since he already had the bike apart. After I went to pick up the bike and while I went to pay for the brake pads, my dealer mechanic moved my bike to where my truck was so that I could load it up. When I got back by my truck, the mechanic was adjusting the shifter as he noticed that it was out a little. He asked me if it was ok and I said fine.

 

Good info guys, I have an 04 KVF 360 and I noticed it making that noise when crawling over rocks in low gear. I adjusted the shift linkage and it's quiet again. Keep the info flowing.

 

Mine has done that since new.

I don't worry about it, it doesn't happen that often, and it isn't getting worse.

I wouldnt worry unless it gets worse....what are you gonna do...fix stuff cause it makes noise.....aaaaaaaahhhhhhhhhnnnnnnnnoooooooooo

 

Zen - others
I've got a 2003(2002) 360 and just took it in to the shop after having the belt replaced.
My orginal issue was a brief squeal as I started off in high range. Thought I needed a belt since it had been 3 years since we did the last belt. After getting belt replaced I started hearing a strange noise as the CVT engaged and went away after my speed picked up. Sound was like a metal wheering noise like something spinning around simular to a bad fan motor (kind of) but more irratic in nature. Turns out the drive bushing and bearing inside the primary drive unit had wore out. I guess this may not be the same noise but It appears that the noise is synced with the engine RPM and not ATV speed, once ATV speed reaches about 5 mph sound disappears and doesn't return until I start out again. I also learned if the pulleys are adjusted properly or on the loose side this will cause the helicoptor sound when sitting still in gear, they said it was the weights lightly tapping the side cover. After they adjusted my primary drive (before we found the bad bushing) the helicoptor noise had vanished.

Probably not much help.
