	I have a 92 Arctic Cat 550 EXT Special. When the clutch engages at about 4500rpm it makes a clunk sound then away I go. Can someone tell me why or what is causing it. Rating: 0 Quick Edit Edit Topic

	Sounds like and old belt. 4500 rpm's is a high engagement and clunks because the belt locks into position hard. Like dropping the clutch in a car. WHOP! And away you go!

	Quote originally posted by SKILIE301 Check the chain tension. Yep, although it could be a number of things, the chaincase is the most likely culprit. Rating: 0 Quick Edit Full Edit

	does it use cleats? i had a old sled (i never found out wat kind or anything) it made clunkin sounds too, i checked the track and one of the cleats was bent and kept hitting the tunnel wen i rode it, wich equals the clunkin sound! Rating: 0 Quick Edit Full Edit

	yeah i had a buddy and when he went off it made a deep clunk and took off. does it feel weird when you go. see if the belt has a angle on it. if it does it could be bad. i would check the clutch stuff before the chain case. try tighting the jam nut on the chain case second and if that doesnt work then go deaper. getting in there is a pain in the u know what. 2002 Zr 500 CCE D&D pipe ported polished y 6 inch riser Acerbis Handguards Chrome winshield Pro-glider Rack Rsi pad Ripped graphics Fox snow pro shocks clickers Rating: 0 Quick Edit Full Edit

Can someone tell me why or what is causing it. on my old 94 zr7, a motor mount was broken, and everytime i took off it made a clunk. so grab the motor and see if it moves. its shouldnt move much if its ok, if its broken it'll move an inch or more(probly more). so inspect all motor mounts.. 1st sled-> 1985 polaris 250 2nd sled-> 1994 polaris indy 440 3rd sled-> 1994 Arctic Cat ZR700 now -----> 1996 POLARIS RMK 500EFI o.O yam blaster alottamods Rating: 0 Quick Edit Full Edit

	There should not be any "clunk" or any other noises associated with starting off. Check all motor mounts and the torque stop first, then check that the chain is not loose and then the track. Since the chain tension is held by a spring tensioner on this model, make sure that it is working properly and that the chain is not stretched out.
