Timing Chain Noise CBR600 F4i How to Fix It.

Timing Chain Noise CBR600 F4i How to Fix It. This is a VERY COMMON problem on the CBR600. Fortunately it's pretty reasonable to fix. There's a small 8mm head bolt straight in line with the tensioner that unscrews to reveal an access hole for a small screw driver. Twist the screw in the hole clock wise to retract the rod and counter clockwise to tighten the chain by distending the rod.

Thanks a lot mate! Best information out there everyone is saying put a manual tensioner on or you'll just have to put a Honda one on every few thousand miles. I did this last night as mine had minor chain noise but I wanted to get on top of it. Took a bit over an hour start to finish as I dropped that 8mm bolt and washer. I only turned it about 1/4 of a turn counter clockwise but can report that the noise is completely gone!

@bigginM4C You're welcome- way to go!

Only thing I had to do was pull the fairings on the clutch side and take off the tool box. It's right next to the frame covered by some type of black plastic cover that just folds out of the way. It was pretty easy but on the RRs the frame is very close and there is no room to put a small screw driver in it without taking the tensioner off. If the spring is still good you have to hold it in place while you put it back on. Royal pain in the butt. End result was worth it not paying a shop $200

@greenmarine5 Cool. Way to go man!

I agree Honda should have a recall..This issue is not only with the F4Is it's with the RRs as well..My 2005 RR just started making the noise, doesn't start till about 7000 RPMs when it first starts it's going to sound like something is vibrating when you pull in the clutch it goes away, it will gradually get worse. I had a manual tensioner put on at the suggestion of my buddy that does what you do.

Most dealers around here have now idea they just want to sell bikes. Excellent video TY

@greenmarine5 It's a lot easier to make money selling the bikes than it is fixing them. You can make a thousand dollars in an hour vs. Maybe hundred in an hour.

great video man...that tensioner looks identical to the fireblades too.

Brian just went threw my Timing chain tensioner on my 05 cbr600rr. Mine was stuck, after I took it off and used the screw driver it worked fine. LOL I put it back in fully extending bike wouldn't stay running. So I had to take it back off retract the spring/shaft hold it there and put it back on and let the shaft spring onto the tensioner pad inside. Bike runs great now with no noise..Thanks a Million man I'd buy a ya beer if we were close. You are a huge help!!!!!!!!!!!!!!

@WOTGTP98 Twisting it back will buy you a few thousand miles or so. Sometimes longer.

so do i still need to buy a new tensioner for mine? im pretty sure this is the noise. i didnt think you could fix it just by twisting it back?
