i have a 94 f2 and when the bike is cold and i start it it makes a clicking noise, the noise lessens when it warms up but i can still hear it....loose valvs?

 

i would say--> cam chain tensioner ... wait for a second opinion but thats where my money is..

 

Tensioner Lifter. Get the APE manual cam chain tensioner lifter. Worth the $$$$

 

+1 cct, Put your ear down on the engine case, should be able to hear it in that area to make sure.

 

add a drop of oil in when its running... I had a loud noise and that made it go away... weird i know but give it a shot..

 

I'm not sure, but I don't think engine temp has anything to do with cam chain noise. 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.

 

I have that same noise I was told my ignition timing might be off. But what is the cam chain tensioner?

 

it is located inside the right side cover(sitting on the bike) it keep tension on the cam chain..once you open up the cover you cant miss it.

 

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.

 

so is cam chain replacement something I should be able to do myself? Just recently my bike started making a clunking sound constantly intstead of just start up. it still runs ok but i am increasingly worried abbout it.
