Well, if your new noise sounds like a buzzing that changes with engine speed, then you might want to remove one of the spark plug tubes and check to see if the chain has been rubbing on the outside. I run 10-40 Valvoline motorcycle oil spring and fall, and 20-50 during the hot months..change it every 3,000 miles along with the Kaw filter specified for the bike. I change the final drive oil every second engine oil change. There are two removable plug tubes, R/R and L/F...

Decided to check the tensioner travel while waiting on the hex tool to arrive, and found them both to be within 1/16" of full extension. The front tensioner is  a full 1/4" recessed, the rear slightly less. According to "Gadget", it's getting close to extender time. I checked and rechecked the new top end noise, definitely a new "tinny", noise that does vary with engine speed. I don't know if the tensioner(s) are just about to click over to the next notch, but in any event I won't undertake any multi-day road trips yet.

Now for the big question. The front cam chain tensioner is going to be a real bear to pull and replace with the Air Cleaner Duct in place. I'm not even sure if it is possible. If anyone has successfully done it with the duct in place, [u]please advise![/u]

Thanks! That is a good idea. I'll read up on the removal, check on the price of the hex tool and go from there.

103,000! Wow, Troll. That's downright impressive and encouraging. I'd be interested in knowing what weight oil you've been using. I've used 10/40, but get more what seems to be bottom end noise, and 20/50, but get more top end noise with that.

I did raise the idle when I took it off the sales lot. It was too low then and the salesman (Harley owner) said that was where it should be. We know better!

The reason for my concern was a "new" noise which wasn't apparent with my helmet on. I encourage everyone to take their bike for a short ride, sans helmet, every now & then. I was surprised at how much more the different engine sounds can be heard. Anyway, the new noise was not a simple "tick". It had a much faster and irregular rhythm to it and at first thought could be the speedometer cable. A new noise always bothers me.

Other than that, the bike runs great, no problems.

first off, make sure you have the idle set correctly. Too low an idle speed (normal is 950-1000) will make the engine noisier than normal. People say the chains stretch, but I'm thinking it has more to do with the nylon guides wearing. That said, I have almost 103,000 on my 1500 as of right now, and no reason to fiddle with the cam chain tesioners.

A search here didn't reveal at what mileage the tensioners need checking. No mention was made in the maintenance schedule in the service manual that I could find. My 02 engine's at 21,000, but I have no idea how it was run or cared for, for the first 19,000. There is ample upper end noise and a lower end knock that others say is normal, but if my auto engine sounded anything like that I'd be very concerned.

Not having heard any other 1500's for what is considered "normal" noise, is there a range of mileage that is advisable to check the tensioners?
