Question about Yamaha Motorcycles

1 Answer

My 1994 VMax is making a noise when I rev the engine. Thought it was the timing chain, adjusted the tension, but still making the noise. Does not sound like a bearing. It does sound like pebbles in a tin can though.

need tohave your valves ajusted. intake valves should be about 5-thousnds, and exhasut should be about 7-thousands. be in all, the slite tap you are hearing will not hurt anything. Sometimes times a little lose is good to keep from bending a valve.

SOURCE: timing chain tensioner adjustment

all v twin engines are noisy, if you could totally silence the exhaust noise, you would be horrified how awful the motor sounds, it could probably do with the cam chain tensioner ADJUSTING. i wouldn't think it would need replacing. unfortunately the manual only recomends this being done by a qualified tech, i have a xvs 650 with same trouble. i would adjust myself if i could find out the correct tollerences.

SOURCE: A rattling noise coming from the engine.

Could be your Flywheel,The yz426 has a riveted flywheel,over time these rivets wear from the flywheel spinning around,causing a "rattling sound"or it may be your timing chain is loose or has been stretched.

Timing chain marks for E 38 BMW engine,

there is a chain tensioner located on the LHs tensioner guide and it is adjusted to 6 inch pounds torque. There is a lock nut on the adjuster that is tensioned to 37ft/lbs. the full procedure to replace the chains is involved and to understand the procedure I suggest that you get a copy of the workshop manual for the engine before you start

What would make noise behind timing chain cover on 2001 kia

IF this noise is a shrill sqeauling noise, their is a good chance it will be the timing chain tensioner pulley/adjuster. These are an inxpensive item and should be replaced each time the timing chain is changed. It is very advisable to get this checked asap, because if the tensioner and chain fail, it will lead to a complete engine failure, wich will be very costly. Being a 2001 model, it may have quiet a few kilometers on it, on the tensioner could be original. Replace these components first, regardless. If noise persists their maybe wear in the valve train.

When warm i notice a cam chain type noise. could this be a worn cam chain tensioner . the bike has covered 36000 miles

it can either be a worn tensioner or need for a valve adjustment. if you rev the engine and noise goes away, you need a new cam chain tensioner. if the noise remains or gets worse when you rev it up, you need a valve adjustment and should replac the tensioner anyway. 36,000 miles on the motor is definitely mileage for an adjustment if it's never had one.

top end noise usaully the sign of needing a valve adjustment. some occassions just need a new cam chain tensioner. when you rev up engine rpms, if the sound goes away that means your tensioner is bad and not adjusting properly. if the noise gets worse then it's time to let a technician do his thing.

Timing chain adjuster

I'm not sure what model your Jag is but, for the XL8+ there is a TSB/Recalls (Technical Service Bulletin) for:
Some vehicles within the above VIN range may experience a rattling noise when the engine is started. This noise may be caused by the secondary timing chain tensioners. Research has shown that a noise can originate at the chain tensioners to cause a resonance in another part of the engine.
A revised, spring assisted, secondary timing chain tensioner has been introduced to eliminate this concern, commencing at engine No. 98102106XX. Introductory VINs are not yet available. In case of a customer complaint, the revised tensioners may be installed on earlier V8 engines.
But then again, I'm not sure exactly of your model, if you get back to me with the exact model, I can check for any TSB/Recalls for you :)

Poss loose timing chain- is there an external adjuster?

The cam chain tensioner on the R6 is external but it is also automatic. If you are hearing cam chain noise, the tensioner could be getting close to ratcheting up one notch to quiet the chain down. The chain could be stretched enough to make noise but not loose enough to let the tensioner take up the slack yet.
You can loosen the adjuster mounting bolts very slowly until you hear 1, and only 1, click. Then bolt the tensioner back down and start the engine and see if it is noticeably quieter. If it is, leave it alone. If the noise is unchanged, the chain was not loose and the noise is coming from somewhere else.

I have a 1994 Yamaha Virago 535cc. I want to know

There is no adjustment, it has automatic cam chain tensioners. If it is making cam chain noise, it could be right between ratchet steps and getting ready to click up to the next step.
