07 Arctic Cat 650 H1 clutch noise

Recommended Posts

Had clutches apart when reringed engine. Now when I come t a stop there is a clanging noise coming from housing It also seems like something doesn't disengage when I come to a stop. It doesn't do it as much if I bring the rpm up a tad when I stop. I read from an old post to clean everything with brake clean. I'm going to try that first, but if anyone has any other Ideas like to hear them. Thanks Bob.

Does it sound like a bell ringing? Sometimes when you stop suddenly the belt wedges in-between the plates and holds the primary open allowing the clutch to make noise. To me it sounds like a bell through the snorkels.

I would also pull the cover and make sure the primary and secondary nuts are tight, they should have been put in place with red loctite.

Sort of like a bell. When I slow to a stop it will actually stall the engine.

If the engine stalls there is definately a problem. Check the two bolts that hold the clutch on. That is the most common problem with them backing off. If this is the case be careful if you still choose to run it so you don't crack the cases.

It could also be the rollers sticking but I doubt it.

Take the clutch cover off, remove the clutches, clean everything with brake cleaner and then reinstall the clutches with red loctite to about 250 ft lbs of torque (check the repair manual for exact number).

Thanks for the help and insight. Plan to take back apart and clean and re torque both nuts. I'll post my results. Thanks again!

Did I mention that I also replaced the timing chain when I put the new rings in? That means I had to remove the wet clutch and one-way bearing. Green dot out Bobski. I had the one way bearing backwards. Hope I didn't riun the bearing, might order new one just to be safe. Hope my mistake helps others. Thanks for your insight.

Ahh so the one way bearing was the other way bearing. Good detective work. Hope it works out

Glad to see you found the problem. My guess others might have similar symptoms when the one way bearing is bad, it is definitely good information to have.

What is the benifit of leaving that bearing out? I read that alot of riders take it out.

If you download the service manual for your machine it has all the specifications for torque.

Are there shims between clutch sheaves? I know on a sled the shims set the belt deflection...and when you  worked on it ...it got out of spec. Just a thought.

It eliminates engine braking. Personally I like engine braking, but if you don't, remove the bearing.

      recently picked up some project bikes off CL for cheap.  got a honda fourtrax (the ancient 4x4 kind with the straight axle in the front as well as the rear and a back-up kick-start)  plastics are crap, but my goal is to get running like a champ and patch the plastics up and sell to one of my many friends that want a reliable 4x4 for dirt cheap and doesnt care what it looks like.
      so the former owner says it needs carb rebuilt, but its sat for 3+ years since so who knows.  things I see:  carb is missing (he gave me a box of parts along with the bike), engine turns over and feels good with kick-start, brakes need work, battery missing (That always puts me off, cause then I know most likely someone's been tampering with the electrical.

      I was given a "Go-Kart" its an old Carter brothers dlx150 but the engine is not the same that came with this Kart. I am trying to ID it so i can look at getting some parts for it. the pictures attached are of the motor and the only ID marks on it. I am thinking its some sort of 200cc from the 1980's does anyone have a better Idea? I am really trying to get a rebuild kit for the carburetor. on the carburetor is  Keihin 63 AA YKT

      Problem: The ATV starts and runs at idle perfectly. But as soon as I open the throttle, the engine starts to slow down until it stops. On the attached video you can hear the sound of how it works: see video below
      Prehistory: there is a Polaris Sportsman 500 1998, which for about 1.5 years stood in repair, including also replacing CDI with one taken from the same ATV. Finally, the vehicles were on wheels, traveled several kilometers and overheated - forgot to fill the antifreeze Came back home in small moves. The next trip started well, but after 10 km there was a feeling of a small drop in power (even as the vehicle got warm completely) but still drives. Next trip - the situation is repeated. The next test of ATV through time and a huge loss of power from the very beginning. The engine sneezes, does not want to go more than 5 mph.

      What has been done: the carburetor has been replaced with a new one (inexpensive, $ 40), a new spark plug, a new ignition coil, the engine head has been removed, the piston is in good condition, valves were corrected - but the problem was definitely not in them.

      Ignition control unit is suspected. Who faced similar? Please help in solving the problem.
      Thanks in advance.

      picking up atv tomorrow, guys says motor is locked up. he thinks, anyway has been sitting for more than three years. Please understand i have not touched it yet but if his description is accurate im looking for suggestions on freeing it up before  having to tear it down. I'm hoping to get some great info from the pros on Quadcrazy.

      So I picked up a Cannibal that has been sitting for many years. I wonder if anyone can tell me where that vacuum port is on the engine. I’ve found the one to the air box, pressure regulator, and ecu but can’t seem to locate the one on the engine. Thanks in advance for any help.
