If the clearances are OK , this may not be valve noise.
cam chains and adjusters can sound this way

How do I fix the tapping sound from the engine when i accelerate after it has reached running temperature


Adjust the valve tappets (yes, they 'tap') AKA Rockers or find out why the hydraulic self adjusting tappets don't work?

They transfer the downward motion of the cams on the camshaft to depress the valves. There is a thin clearance of about 8 thousandths of an inch with the engine cold. As the engine heats the clearance reduces. Over tightening causes the valve edges to burn, too much clearance causes tapping.

Manual tappets get quieter usually as the engine heats. Hydraulic tappets gets worse as the engine heats as the oil thins.

Tappet noises


the noise from a worn camchain or faulty tensioner can be confused with valve clearance noise valves normally close the gaps as they wear and become quieter

Valve Clearance


Modern cars are hydraulically adjusted at the tappets so there is no adjustment. However the pivot points for the rockers can become seriously worn giving the same noise. The hydraulic tappets them selves wear and allow the oil pressure to drain off too quickly meaning there is a clearance every time the cam activates the tappet. I would have a leak down test done on the hydraulic tappet units and check the rocker shafts for excessive wear.

Intake valve bent, what is the cause?


This can be caused by incorrect valve timing, incorrect tappet clearance, where the valve hits the top of the piston. Hydrolocking can do it also.
Very unusual without help from an outside source.

Overhead valves making noise like they need ajusting


Valve Lash ADJUSTMENT 1.6L Engines NOTE: Measure valve clearance with the engine cold.
  1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
  2. Remove the valve cover.
  3. Set the engine to Top Dead Center (TDC) of the compression stroke for the cylinder to be adjusted.
  4. Check the valve clearance. The valve clearance specifications are as follows:
    • Intake valves: 0.005-0.007 inches (0.13-0.17mm)
    • Exhaust valves: 0.005-0.007 inches (0.13-0.17mm)
  5. After adjustment, tighten the locknuts to 11-14 ft. lbs. (15-19 Nm).
  6. Repeat for each valve to be adjusted.
1.8L, 2.0L and 2.5L Engines The 1.8L, 2.0L and 2.5L engines utilize automatic hydraulic lash adjusters to maintain proper valve lash at all times. Periodic valve lash inspection and adjustment is not necessary or possible. prev.gif next.gif

I have a 2001 v-star 1100 the problem i have a nocking noise in the frount cylinder, set the valves, set the chain guides. the noise is the loudes in the head pipe


You mean the timing chain guides?

If so double check the valve adjustment they may be too high on the clearance making a loud tapping sound or the chain is slapping against the guides due to improper installation.

Yamaha VStar 1100. Valve train noise after starter clutch repair.


The cam chain has stretched a bit making it look like its half a tooth out, the tensioner takes up the slack but makes the cam timing slightly out.
You could have timed the crank 280 degrees out
It should be timed on the T mark for one cylinder & on the I mark (if there is one) for the other.
The marks before the T mark are for ignition timing (firing marks)


Good Luck
Hope this helps.
(If it does then please mark this as 'useful')

2000 astro has intermittent clicking noise from engine compartment


The clicking noise emanates from the clicking of the
valves, and tappet hammers, under the valve cover.
If these are noisy, it means that it need to be adjusted
for the proper clearances and retightened. Have these
items checked to completely solve your problem. These
valves when properly adjusted will give your car good
mileage.

Pinging noise comming from exaust


The 1100 Custom requires the valves to be adjusted every 3000 miles.
It is best to use high octane gas also. Regular or shall I say CHEAP gas will over time cause the pinging or spark knock.

Pinging could also be something worse if it does not go away with valve adjustment and better gas. Get it checked right away.
Kinda miss my ole 1100 custom but the Yamaha Raider I have now does not require valve adjustments every 3,000 miles. And fast.... oh dear lord. :)

Hope this helps!

A fairly consistent tapping noise from the top of the engine between 50 - 70 mph. After 70-75 mph in seems to quiet down.


sounds like a lifter is bleeding out or starving for oil at low revs
check oil level and oil pressure
if thats good lifter or tappet clearance next to check
is engine seviced regularly?
slugde build up can cause problems also
if V6 petrol see a lot of worn valve guides causing noise worse when warm and noise comes in and out at 1200RPM
tappet clearance issue noise would be there all the time
lifter can also come and go while holding revs up
