hey all, new bike owner here. i just got a 91 honda nighthawk 750 and love it. she needs some loving though. i've gotten the chain tightened due to the chain clicking or popping at low rpms, but now i've noticed a new problem. the chain seems to be clicking in a pattern, bout every second or sooner. the guys at the local bike shop said i had a bad sprocket when i went to have the chain tightened the first time. does this sound right? i have heard that the local bike shop has dicked around a few people and they seem a little pricey at 350 for the repair.

anyone have a similar problem, or can you confirm that this chain 'popping' or 'clicking' noise is in fact due to a worn out chain sprocket, or do i just need a new chain. i know that the chain is about ready to be replaced

i have 22,000 on the bike.

thanks for the help

stick it up on the center stand and pop it in neutral. rotate the rear wheel by hand and try to identify where the noise is coming from. Then look at it, or take pictures. Changing the sprockets and chain is a fairly easy job on most bikes.

Chances are that's what it is!
We just had a guy with a CBR954RR come in because he wasn't sure why his chain was slipping when he got on the throttle.
The guy had less than 1/8th in. of tooth left on EVERY tooth on his sprocket.
Had him in, out, and on his way within 2 hours. (Gotta love bike mech schools)

Chain and sprocket, it sounds like. Not a difficult job to do, I did the chain and both sprockets on my dirtbike without any sort of help or previous experiance working on bikes. Just take a little time to go through it slowly, and use a good manual. Shop manuals are best, but clymer manuals work well enough.

yup chain and sprocket. took me 2 hours to change out the chain and sprockets (yes sprockets both front and rear cause your better off replacing both than just 1) on my bike and I had NEVER done it before on a motorcycle. It was pretty darn easy other than making sure the alignment was right.

A good sprocket and chain set is ~$200, and with 2 hours of labor at $60-75 per hour, with tax, $350 is about right. You can do it yourself as described here for the cost of the parts. I could change both sprockets and chain in about 30 minutes on my race bike. A dremel tool is handy to get the OEM chain off and I prefer the rivet link over the clip-on so if you go that way, you'll need a chain tool.

thanks ya'll, i posted this in the how too section as well, figuring it was probably more suited there. i am gonna go ahead and do it myself but was wondering if i needed any special tools to attach the chain (and where to get them), or does the chain usually already come in one piece.

thanks again

I spoke of the 2 that are needed. If you get a clip master link you dont need a chain tool.

those are not recommended because they have a higher failure rate than press master links. I spent $80 on my chain break/rivet tool.

I believe it was that one but the website has changed its look some so im not positive. Either way you can break the old chain with a pin that comes in the kit and then put a different pin in the tool to rivet the new chain. In my opinion well worth the cost since I will probably be chainging the chain every couple of years or so.
