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.

    It still sound like to valves, or the time chain tensioner. usless you have a loose wrist pin on one of you pistons. It hard to put my hand on it thru and E-mail. This low of miles, you might need to check to see it. This bike has any recall or ask your local Bike shop if they have had any problems with this model bike?????

Can the tensioner make the chain to be loose inside the engine an cause it to make noise an show sign of oil on the dashboard?

A loose timing chain tensioner will not cause the oil lamp to light. The noise you are hearing is most likely valve noise due to oil starvation. The oil light comes on when the oil pressure is too low to be safe for the engine. Most people believe it is to tell you the oil level is low. A low oil level can cause low oil pressure is the oil is below the sump, but low oil is not the cause of the light - low oil pressure is. This can be due to a number of things, such as a bad oil pump, faulty bypass regulator at the oil filter, loose sump pipe connection, or even an oil gallery plug that comes out internal to the engine. You need to stop using the vehicle immediately and have the oil pressure checked with a mechanical guage to determine if the problem is the oil ressure or the sensor that lights the light. The chain tensioner being loose CAN cause noise, and that itself is an issue that should be fixed, as in many vehicles a loose chain can jump time, or jam and break, and since many cars have interference engines, either of these scenarios can cause severe internal damage to the engine.

How do you adjust the tensioner on Yamaha F150TXR four stroke 2010

make sure the cams and the crank are in time and all marks align ! check all cogs and guides etc for wear !
if a camchain tensioner is adjustable then it will have a small bolt on the end where you then use a screwdriver or an alenn key to retract pressure or increase slightly normally when refitting ! while the engine is running gentally increase the pressure and you should feel it adjust ! BUT NOT TOO MUCH as it can snap the chain , listen for any engine noise change !! have you had the chain jump and off set the cams ??

I have a 1996 suzuki ls650 savage how do I get the camchain on the bottom gear?

Take off the right hand side crankcase cover, remove the tensioner and the chain's guides and hook the chain to the crankshaft's gear and then pull it up through the cylinder and cylinder head and install the guides back.The crankcase cover will be placed on the engine last, after you have finished with timing your camshaft and have the tensioner installed.

I own a 2004 BMW R1200CL. Almost every time I crank the engine I can hear the valves rattle. I have checked and adjusted the valve clearances to spec. The rattle goes away after the engine starts, but...

Yep, most of these bikes do rattle on startup. The noise is from cam chain slack. A hydraulic tensioner is used in the engine on each side as there are two cam chains. The tensioner leaks down after the engine sits for a while and the chain rattles for a few seconds till the tensioner gets pumped back full of oil again. Once the chain is tight again, then no noise.

BMW came out with an improved tensioner (doesn't leak down as quickly) that you can install on your engine to fix the rattle. Note that it is much easier to change the RHS tensioner than the LHS one.

Good Luck!

How does the timing chain adjuster work? My motor is a little noisy and I was looking to tighten my timing chain. The manual doesnt tell me how to just adjust it. It tells me how to assemble it (not very...

Well I guess the type and model of motorcycle would help.

However, most camchain tensioners are basically automatic. They bear against a long, curved nylon dampener that rides the slack (trailing) side of the chain. This pressure is made by a spring inside the chain tensioner housing itself and is not a serviceable part.

If housing is bolted up tight, all available tension is employed. If chain is still slack...camchain is worn out must be replaced.

Camshaft and rocker arm gaps maybe providing all the noise also, maybe time for a top end service, whatever the bike!!

Replacing timing chain on ttr 90

There should be a timing mark on the magneto, rotate crank until line is visible thru inspection hole. This will position engine at Top Dead Centre. Have head complete with gaskets, valves, springs and camshft in place and position with camshaft chain in ready position, (you have to hold chain thru camchain opening) Place head on and bolt tight (no need to torque down yet) and pull camchain tight on opposite side to tensioner (fully loosened) and feed over camchain sprocket, take up tension with tensioner screw/bolt. This will have engine TDC with valves closed (as if to fire) rotate engine by hand and ensure tracking of camchain and tension is steady on chain. Valves should actuate in time. Have a close look on camchaim sprocket and a mark of some sort should show against corresponding mark on camshaft journal cuos.

Need the Manual: Down load from the link above, enter model, make year and download for free. (It's in four languages however) The relevent detail is in chapter 4-8 to 4-13. I think, Cheers.

I would be looking again at the cam chain tensioner. I have replaced 2 on my 05 so far and it was doing the same thing. the other known problem for noise in the engine like that is the valve guides are know to wear prematurely on 05's and the 03 and 04. Yamaha knows about the problem and will fix it under a one time warranty even if you do not have the extended warranty on the bike. Make sure you talk to the dealer about premature valve guide wear.

1996 Suzuki Savage 650, engine knocks

knocking increases with engine speed ...check for worn wrist pin to piston clearance,rod bottom bearing clearance, very unlikely the timing chain has any kinks with a chain tensioner set properly...a loose chain could make some noise so check the tension setting

Camchain rattle on startup

this could be a sticky cam chain tensioner as the oil gets hot it releases the adjuster to work normaly. 2 bolts it if you wish to take it off and clean it.
