Tapping noise At about 11K mls, I started to hear a tapping in the front of the engine (2006). Now at 20K mls, the tapping is more rapid. No noticeable loss of power or efficiency. Anybody else?

    It sounds like a lifter to me. But some bikes just have odd noises and I haven't heard another 650 so...

Could be a hydrualic lifter that is causing the noise. You would have to take off the valve cover to find out and then put a new gasket on whemn you put it back again.

Hi, Rick I would love to help you with your engine or chassis noise but I just loaned my brand new pair of listening ears to your local dealer's chief technician so he could take your bike for a test ride and give you his professional opinion and estimate about your noise and repair cost. If you are a little short on "DRACHMA" and a Dealership is not on your list of fun places to visit then perhaps the list below will help soothe your worried mind so you can make an informed decision.
1. Bearings---SCREECH
2. Belts---HUM
3. Brake Rotors---BUZZ
4. Chains---RATTLE
5. Clutches---CHATTER

8. Rear Shocks---SQUEAK
9. Starters---CLICK

I have a 2001 harley heritage. Wondering how often I should have the valves adjusted. Thanks

Your engine is equipped with hydraulic tappets just like your car engine has. There is no way or need to adjust the valves. If you're hearing a slight tapping noise under the rocker box covers, this is normal. If you're hearing a loud tapping noise that comes and goes, it could be a roller on the end of a tappet going bad and you should have it looked into.

Good Luck

My gr650 has a slight windy noise in top of motor it also has slight tappy noises when im riding can not hear the winding but can hear it tapping when stopped ,i changed the oil and oil filter thought it...

The upper windy noise, I would keep an eye on but the tapping noise sounds more seriouse.
I would purchase some Slick50 to add to the oils. They do a special grade for particular bike engines and it will ensure you minimise the wear.
I take it this noise has happened recently or has it been getting worse over a few thousand miles or so?
If it has just happened it may be piston slap if it it there at all times or if loudest on the over run little end bearings.
When you are able, check the compression and take the top off to examine the pistons, (broken rings) and bearings.
Hope that helps a bit

I am considering buying a Honda 750 Shadow Aero with 18,000 miles. My wife looked at it today and said she thought she heard a knocking sound in the engine. It runs fine and because of hearing problems,...

Knocks, Rattles, Whining, Clunks, and Grinding noises coming from the engine are not good signs.

Light Tapping noise could be a few things.

A dirty oil filter will cause the top end to make tapping sound until the oil warms up and, then the noise goes away, that might be why you didn't hear it, but she did at first.

If the valves/rockers continue to make noise, it probably just needs the valve clearance checked & adjusted. If they continue to make noise after this, then its a sign of wear to one or more of the valve componets.(rockers worn, lifters worn etc)

With only 18000 miles, its probably just dirty oil filter.

Tapping coming from front cyclinder

Since I can't hear the noise for myself, the only thing I can do is give you my ideas as to the cause. Is the noise a ticking noise or a knocking noise?

First off, if it's not loud enough to make people turn their heads when you start the bike, don't worry about it. Your engine is the old pushrod design and the rocker arms are going to make a little noise. Moving mechanical parts make noise.

Now, if it's a loud noise, my first guess would be that you have a bad tappet. Either the hydraulic part of the tappet is bad and is not keeping the pushrods to zero backlash or the roller bearing on the end of the tappet is bad.

If you're sure your problem is on the front cylinder, pop the pushrod tubes loose on that cylinder. Feel of the pushrods. If you feel on that is loose, there's where your problem is. Pull the rocker box, take the rocker arms out of the lower plate and then pull the tappet block. You'll probably find a bad tappet. If so, make sure you check the camshaft for damage as well.

Good Luck

Tapping sound on top end of engine

sounds like a piston noise, you may have a scoured cylinder, this is common on two strokes.

If you hear a tapping noise from the gearbox then you have a broken gear tooth. Is the sound is present in all the gears or just in one or two gears? If the tapping is present in all gears then the busted tooth is on the clutch hub or the crankshaft drive gear. This is good because it is easier to fix than a broken transmission gear.

If the tapping is just in one or two gears then you will need to remove the engine for a complete tear down. In any event, ALWAYS replace gears in sets. Replace the broken gear and the gear that it meshes with. Don't replace both gears and you will soon wish you did. ALWAYS replace gears in sets.

Please rate this answer. Thanks!
