Clicking on upper left hand side of engine.

I'm trying to pinpoint it. 1984 honda nighthawk 650. Effects nothing with how it rides and only clicks when I rev the engine up. Doesn't do it when I coast with the clutch engaged.

The 650 has self-adjusting hydraulic cam tappets. They can get gummed up and need cleaning. When this happens, it makes a tapping or clicking noise.

One other possibility is a bad exhaust gasket at the head, which is not uncommon either.

Least annoying way is to load it up with a full synthetic motorcycle oil and see if the synthetic can clean it out. Synthetic is more detergent and can clean out lifters. Make sure you use a motorcycle-rated synthetic oil to avoid poisoning the clutch - must say 'JASO MA' or 'JASO MB' on the bottle.

Failing that - take off the cam cover and tear down the top end to remove the hydraulic cam tappets. Any of them that have been stuck or sticky should be easily detected. You can then follow one of several methods on the internet to clean them.

Now it just sounds like a loose chain. I believe it's the tensioner

I think it may be the clutch because the chains have no wear on them.

Clutch is not chain driven and is on the bottom towards the rear.

I'm not saying it's chain driven. I think it can be the lower chain to the stator, or my clutch, or a bearing. My motorcycle has been randomly running out of battery.
I just took a video but my phone won't let me post. I'll post when I get to a computer

Why would you need them to make a bearing? They're still available from Honda, last I looked.

Should be still available, but there's a catch. More info here: New to the Forums

They're listed as obsolete parts in most Honda databases, but that doesn't mean they're not available. Many dealers think it does, but it doesn't. They need to run a dealer search to find them but most dealer drones don't know how to run them.

I also commend this post to your attention: http://www.labusas.org/forum/showthr...-Honda-part-II

Also on a side note how do I know which bearings I need. I read there are 5 different types and there's a stamp somewhere that will tell me which ones. Where is that stamp

See the links I posted in the last post above. The stamps are on the underside of the bearings.

Finally opened up the original engine and I found out I need a "black" bearing. Can't find any anywhere but I still have good bearings on my other engine. But that one has no stamp. How do I tell by the code on the bearing what type they are

Are you saying you can't find the stamp/code on the bearing? or you can't find it via a google search?

Post it here if you have it, perhaps we can help search.

Factory service manual for that can be found here: https://app.box.com/motorcyclemanuals

The color code is on the side of the bearing or the edge of the bearing, not the big top or bottom bearing surfaces. Get the manual from the above link (it's not mine) and look at Section 12, which starts on page 165 of the PDF file. The information as to which color bearing you should select starts on page 12-6 or 171 and runs through 12-9/174.

What happens if I use a brown or a black bearing inside a spot that needs green? They are both a tad bit bigger

What if you box them up and send them to a bearing place? they can take measurements and send you an exact fit.

or measure all the diameters with a micrometer and send them the info.

If you have most in that size already, find what's the closest match you can find on all measurements, and use it.

Just remember that this is random, guy-who-thinks-he-knows-it-all, internet advice. Take it with a bucket of salt.

I'm not sure where you're located. If you're in or near a big city, just bring them in to a bearing supply. I've had good luck with all kinds of bearings. Bicycle, skateboard, and for motorcycle wheels.

I'm sure you have lots of supply places close by. Give it a try. They'll either have what to need or can order them in.
