To check for cam chain noise, put you ear close to the right side of the motor just in front of the transmission. But if you have $75 to blow, a new tensioner is easy to install, and would give you a quick answer. _____________________________ 1993 600F2 Full F4i bodywork and gauges D&D slip-on K&N filter DynoJet Stage 1 Vortex sprockets SS braided lines front and rear Shorty Pazzo levers Hotbodies undertail (in reply to AlpineCBR600) Post #: 6

RE: horrible noise - 1/18/2007 7:05:02 PM    racer212 Posts: 330 Joined: 8/15/2006 Status: offline The stock cam chain tensioner is hydraulic and runs off engine oil pressure. When the bike sits the oil can drain out. When you start up this can allow your chain to be slack which can make a hell of a noise. As oil pressure rises and the oil warms up (become for viscous) the tensioner tightens, the slack goes away and everything quiets down. The stock CCT on a lot of sportbikes (not just F2s or Hondas) arent all that great and wear over time.. basically they dont pressurize as well as they are supposed to. This means your cam chain is not under correct tension (so it makes noise), and the worst case scenario is that the cam chain jumps the sprockets on the cams. Mr. Valve, meet Mr. Piston.... things get very ugly and expensive. The cam chain is inside the engine case on the bikes right side. If you have noise there at idle, but it tends to go away as RPM's increase (increased oil pressure) and the engine warms up. A little noise at start up is normal. If it never goes away, its time for a new one. _____________________________ Scott Newlin www.rocketcitypowersports.com 2005 CBR1000RR - Race Track Weapon 1999 CBR600F4 - Weekend thrash monster 1993 CBR600F2 - Babe magnet (in reply to bindelsf2) Post #: 9

RE: horrible noise - 1/19/2007 4:38:24 PM    racer212 Posts: 330 Joined: 8/15/2006 Status: offline My opinion is let a pro do it. Its not hard, but if you mess up and get the timing off you could be in big trouble. _____________________________ Scott Newlin www.rocketcitypowersports.com 2005 CBR1000RR - Race Track Weapon 1999 CBR600F4 - Weekend thrash monster 1993 CBR600F2 - Babe magnet (in reply to f2rocket) Post #: 12

It's cost less than an hydrolic. Is this a good idea or i simply put a new on and that's it ? (in reply to racer212) Post #: 13

RE: horrible noise - 3/2/2007 1:13:27 AM    BikerBoy930 Posts: 75 Joined: 2/18/2007 From: Vegas Baby!! Status: offline Should a cam chain tensioner make a "clunking noise"? Ive always heard a slight "grinding noise" for 2-3 seconds is somewhat normal after start up (tensioner)--as long as it goes away..Clunking noise sounds more serious..
