In the past few days my bike has started riding different. Instead of having a constant sound it now sounds like its cycling. Doesnt do it when idling and i even feel the movement and not just the sound. I first brought it to a mechanic and he said the chain was too loose. He tightened it and the effect of the cycling was less but still there. Then the chain began to make a noise like a winding noise. I assume its the chain since that was the only adjustment done to the bike. Another guy says i need to get the bike resync'd and jetted. He tells me my chain is fine. The first mechanic said the chain may break and i need to replace it soon. Tightening the chain made it run better but i still have the problem with it cycling and its noiser now and not as smooth at higher speeds. I believe the noise is just the chain winding goin really fast. Im not experienced with this so if i explained it poorly i apologize. But ANY help would be appreciated. I got 2 different opinions and i dont have extra money to spend on stuff that doesnt need to be fixed. Anyone ever have a problem similar to this?? Ask specific questions and i may be able to explain more... I have a 91 CBR F2. Thanks for the help.

Take a look at the chain, If it has about an inch of movement up and down, it's adjusted OK. There is a mark near the adjustment screw that tells you if you need to repalce it or not. Also look for stiff links. That might also be an indication that it needs replacing.

If it need replacing, spend the money. I doubt that this is what is causing the cycling though.

Are you sure it's the chain? If so, spend the cash and replace it along with the front and rear sprockets. It must be pretty bad to actually make noise...

The reason I ask are you sure is that Hondas of that timeframe are known to have troubles with the cam chain tensioner. That WILL make noise and it WILL affect your bike's performance if it's going. Not a big deal to fix - as long as it's done before it breaks. If it does break, you'll likely have to get another bike, because it won't be cost-effective to fix.

my cam chain tenshioner has been mentioned before when i had other noises so perhaps this time it is that. I'll have to see what some mechanics say. Is there a way they can tell without having to spend money for them to 'inspect' it? I cant say for sure if its the chain or not i just assumed so since i didnt get the winding noise until after the chain was tightened. I figure it has to be whatever was changed/altered before the problem arose. The cycling however started before it got tightened and still does it a little after. I think i'll end up changing the chain and sprockets since theres not much room left for tightening on teh chain anyway and get the carbs resyncd and jetted. Do you guys think it needs a resync and jet? Again i cant really spend money on something if it doesnt need it. Thanks for the help guys. Trying to resolve the problem asap because its putting a damper on my riding experience...

I had a 98 F-3 and the cam chain tensioner made noise, common on CBR's, but it had no affect on performance at all. The cam chain tensioner problem is more of an annoyance than a catastrophic failure waiting to happen. I would replace the chain and sprockets, that will eleviate any doubts in that area and while your at it have the mechanic inspect the shaft, it may be bent.

If I'm shootin at ya and ya stay still, your probably safe.

tell me more about this cam chain tenshioner.... what sounds does it make, will make, what it feels like when it happens... every scenario off the top of your head. I do have a sound thats been there for a while but never figured it out. Sounds like a spring or something jiggling around. That may be contributing to my problem if not the actual problem. Im pretty sure i need a new chain too. Anyone know the specific name for the temperature sensor that tells the fan when to turn on for the radiator? The mechanic told me to get a temperature sensor but when i talked to parts they asked if it was the switch sensor or something. Whats it gonna cost me to get the cam chain tenshioner fixed?

OK.. currently when i get the sound it sounds like im on train tracks. I dont realy think it has to do with the engine because it doesnt sound any different then normal when in neutral or with the clutch disengaged. Its only when in gear and riding.

ok check that chain if it sounds like your riding on rails. also push your bike forward verry slowle and feel if there is a change in the force you must aply when pushing it forward to keep it moving and at the same time look at your chain if you see it tighten and loosen you must realy replace it asap couse if it breaks it can do alot of serious damage to you and the bike
