I'd love to solve this damn engine rattle noise I have - it's really bugging me.
'06 model, valve clearances are perfect, I replaced the timing chain tensioner even though the old one was good. The clutch basket was also replaced.
The rattle occurs under light throttle between 4-6K in the mid to upper gears. So, if you're cruising at city speeds in 4th you hear it. Same with 5th at slightly higher speeds. Same with 6th at slightly higher speeds. Not lugging, just cruise conditions with light throttle. I can drive around it by increasing RPM. That is sweet and that's what I want.
It's done it since I got it at 40K and it now has 50K. It's not getting worse, bike goes like snot and I'm sure it's not the engine.
I'm tossing around the idea of pulling the engine over the winter and replacing the countershaft along with the mainshaft bearing. It appears the bearing on the coutershaft is not serviceable separately.
Tomorrow I have an OE 16 tooth rubber coated sprocket coming in to eliminate that from the equation.
It's not inconsistent - you always hear it, especially at 5K when cruising. I never hear it in the lower gears. I also don't hear it under WOT.
I've seen some posts from others about 5K rattles but nothing definitive from them.
Anyone know of any common issues with respect to 5K rattle or whines?
I know it might seem minor but after all the work I've done I want that smooth Honda sound! :smile2:
