Question "clacking noise"... PLEASE HELP

Kind of hard to notice, but when revving the engine, as the RPMs go down, I hear a "clacking" noise. On the left side, it's in the front cylinder, on the right side, it's in the back cylinder (or so my untrained ear thinks anyway). I'm VERY new to working on bikes, so I don't even have a clue about most of the parts or what they do lol! Any ideas of what this is, how to fix it, or if this is normal?

Sounds like the ACCT to me. Try the Grambo Trick first and see if it's better. I was doing that but then I modded to MCCT's.

Click on the underlined "Grambo Trick" and it will take you to the thread that explains this. Also if you haven't downloaded the service manual, I would do so. That way you can take a look at some parts and such even if you don't wasn't to do any servicing yourself. I forget who has the d/l link in their sig, but I'm sure someone remembers.

I had the same problem I pulled both ACCTs the front one seemed to be OK the back one was sticky. I sprayed it with WD 40 and compressed air until it worked smoothly. After I replaced them the noise was gone. I got most of the info from this forum. So thanks to all.

I have a few tips. When removing the front ACCT You will have to move a loom from the inside nut. I found a pair of needle nose pliers useful.

When removing the back ACCT it is necessary to remove the coolant overflow bottle.

BTW my bike has 17,000 miles on it.

All who wander are not lost

Hi and welcome to the forum
Clean all the electrical connections and get good grounds, coat with di-electric grease to protect them, fit a new AGM maintenance free battery these bikes need a very good battery, see how you go with that to start with, let us know what problems you have with the electrics be more specific.
