Timing chain issues

I have just bought a second hand 530 2010 exc, a dirt tricks tensioner was fitted before I picked the bike up, about 2 hrs into the first ride the bike stalled and there was no compression, just air back into the air box. pulled off the rocker cover and found the chain snapped .what could cause this to happen? is it possible to fit the tensioner incorrectly? or are there other reasons? Regards Russell.

Sounds like you could have bent/dropped a valve, causing cam shaft to seize and break the chain. Can you turn the cam shaft? Do the valves move properly?

The YZ is a dirt bike as is. The WR is a street bike and has more accessories on it.

  • Remove the body parts you do not want to get broken. Turn signals, tail light, speedometer, tachometer and mirrors are the main things. Fenders and headlight are possibilities also but the fenders tend to keep mud off the the engine and your body while the headlight allows you to ride at night.
  • Change to a larger rear sprocket. Two or three teeth will make a difference. This will make the bike to " quicker " off the line and out of turns and provide more torque than stock. Top end is a bit slower but with all the twists and turns you seldom get to top speed anyway.
  • Get a heavier flywheel. Yamaha has one but the cost is about $105.00. An aftermarket flywheel may be an option that would cost less.

SOURCE: Our 2000 Yamaha TT-R125L engine won't fire. It is a kick start

Here are a few things to do >>
How old is the gas in the gas tank? Get fresh fuel.
Remove the water trap bowl at the bottom of the petcock, (gas valve). Any water or trash in the bowl? Drain a cup of gas from the tank. Is there any water or trash in the cup? Clean the bowl and filter screen if present, then re-mount them, ( not all bikes have a water trap bowl or screen ).

Install a new stock NGK spark plug and try to start the engine. If the bike doesn't start and run properly then shut off the gas and remove the carburetor from the engine.

Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray into all the little airways and fittings in the carb. Remove the two screws on the outside throat of the carb and spray into the screw holes as well.
Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two screws down. Only screw these in until they LIGHTLY seat. Now turn each screw one and one half turns outward. Put the rest of the carb back together, clean the air filter and install the carb. Let the float bowl fill then start the engine. Set the idle speed with the idle screw.

I am uncertain if the bike has ran for you or not. "Did pull the spark plug and kick started it." If the bike still will not run then the cam chain may be out of time. Why was the tensioner off the bike?

Please rate this solution. Thanks budx5!

SOURCE: Engine stalls

I assume your bike has been in storage for awhile...Your engine is running on choke ONLY, that's why when you cover the air inlet it's the same as what the choke does.....your jets in the carb are clogged and will facilitate a removal and cleaning of the carbs my friend.....find a trusted mechanic and you'll be rolling in no time...Good Luck to you......Tim

Dirt bike cam shain tensioner

You must remove the entire tensioner and leave it out while you swap out the sprocket. Set it to it most retracted position and then install. Adjust it after it is installed. Make sure you have some slack or you will break the chain.

Bike chain skipping

Bike chains are slightly different determined by amount of cogs on rear sprocket. If you havent changed the chain, adjust the tension of chain.If tension is ok-sprocket would be damaged(teeth worn,slightly rounded)but if same prob on different gear, chain tension/incorrect size chain is problem.
Hope this has been helpful..

Just bought a new 455 Rancher, within 15 minutes of use the chain fell off the guide. Could not put this chain on guide again. Tried brand new chain and within 15 minutes of use, chain came off of guide...

if you loosen the nuts holding the bar on there is a tension screw on the opposite side from where the nuts are you should see it if you look from the front of the saw by the muffler you need to use it to put the proper tension on the chain if you turn it clock wise it should move the bar out tightning the chain you want a tiny bit of slack in the chain it should not be dogged down tight with the tension screw if you go counterclock wiseit should release tension. once tight tighten screws to hold on bar and spin chain by hand should be able to spin chain if not it is to tight. hope this helps

How do i tension the chain ?

Loosen the rear axle nut, turn the adjuster screws on both sides of axle evenly until chain has approximately 3/4" on street bikes, 2" on dirt bikes. Be sure to rotate the wheel to find the tightest point in the chain, (chains stretch unevenly), and make your adjustment at that point. Re-tighten the axle nut and tensioner jamb nuts if present.

How do you adjust the timing chain? does the bike have to be running or anything like that??

No! Generally, the timing chain or camchain that controls the valves is tensioned automatically. To change the position of the timing is not possible without a tear down of the top end of the motor, but moving chain just one tooth would result in severe damage to your valves. piston, rockers and cams etc. Minute valve timing is achieved by camshaft node shape. Camchain tensioners are so designed as to take up the slack on the trailing side of the chain. when chain begins to stretch and wear past this tensioners limit, your chain MUST be replaced before inevitable engine death or worse!! Electrical timing on post breaker points bikes (mid 1970's) is controlled by the placement of stator backing plate in relation to the pulse pick up coil. Some engines do not have any room for change here, others have about 6 degrees rotation. This can only be done with a stationary motor and is a matter of trial and error. Generall a mark is etched at TDC as is the magneto rotor. Your bikes make, model and fear would be needed for further assistance. Cheers.

Installing new cam chain however the chain is very tight no play with out the tensionar is this a problem .

yes it will be. the chain will pull the cam down with too much tension without the tensioner, does the bike will start to ride unbalanced.

consult the recommended cam chain with your user's manual and avoid engine damage
