If the chain and sprockets are in good condition and adjusted properly ( 1 1/2" slack ), you should check the rear wheel sprocket dampers. These are made of rubber and can deteriorate over time. If the dampers are bad you will be able to move the rear sprocket forward and back while the bike is sitting still. It is an easy fix to replace them, just remove the rear wheel and sprocket. they are model specific parts and should be available from your local dealer.

    The counterbalncer can be adjusted while the engine is stopped. There is an adjuster on the lower front part of the crankcase that has a pinch clamp. simply loosen the pinch and turn the center portion (flathead screwdriver) until it is lightley seated and then back off 1/4 turn. This adjuster is an eccentric and turns the counterbalance closer or farther from the crank gear. If a gear whine is noticed while the engine is running, just loosen up a little.

    Thanks and I hope that this helps,

I need to know the size of the center hole on a 19 tooth transmission sprocket for an apc mini chopper Thanks

Why do you need to know the size of the centre hole. That one look in great condition. The size is the size of the shaft it fits on, so you measure the narrower distance, which is between the sprocket tooth that is under the middle of your thumb nail, to the second tooth past your index finger. All this links have info.

    I resently replaced my inner primary with a belt since then i still have problems oil leaking from my primary i shut down all my oilers but i still have a large access of oil leakage

    Are you sure it's oil and not gear lube?

    Sometimes the seal behind the transmission drive sprocket/pulley goes bad. (I had this problem myself)

    Next up could be a seal behind the engine crankshaft sprocket/pulley.

    Finally if you have an oil line from the oil pump to lube the primary chain (which you no longer have), remove/plug the line.

    Transmission fluid levels

    The primary case is not marked. The book says that between 32 and 40 ounces of oil is to be used in the primary/transmission case. This oil lubricates both the primary chain and sprockets as well as all the gears in the transmission. The oil will not be visible inside the case. If it were, there would be too much oil and it would make the clutch "drag" making it impossible to find neutral with the engine running. The sprockets and chain are lubricated by a mist of oil generated by the starter ring gear on the outer clutch drum slinging the oil all in the primary case when the engine is running.

    Some of the older Sportsters had a threaded hole with a screw in it towards the bottom of the forward end of the case. One would remove the screw and fill the primary until it started to run out of the hole.

    Good Luck

    80 harley flh acts like its stuck in neutral but

    Have you checked the front final drive chain sprocket. These sprockets are quite often neglected since they are so difficult to get to. You must pull the inner prirmary to get to it. The old four speed transmission is a tough ****** and I don't recall ever seeing one fail unless it was run with no oil. Check your final drive chain. Shine a flashlight behind the inner primary and check the teeth on front sprocket.

    Honda vibrations

    This one's a little tricky cause it could be a few things.
    I'll try suggestions in the order of probability
    • Worn out chain & sprockets.(Or chain too tight or has a tight spot) Check this by raising the rear wheel off the ground,in neutral & spin the back wheel. If the chain & or sprockets are worn you'll feel it & hear it when you spin the wheel. If it has a tight spot,set the chain tension at the tight spot & lubricate well
    • Loose engine mounting bolts. If loose re- tighten.
    • Worn front sprocket shaft bearing. to check this(if chain seems ok) Remove the chain(note joining link direction of the circlip. The closed end faces the direction of rotation)Bike in neutral, turn the sprocket shaft by hand. It should turn smoothly.If it is notchy thats not good. It is a major job to change & can be expensive(So i hope its the chain &/or sprockets)
    • Broken tooth on a gear in the gearbox. I hope not as again a more difficult & expensive repair.
    Hope this helps you narrow down your problem

    Sir, I own a Passion plus Bike 1996 make. 1.What would be the reason If I experience chain sounds-Usually while changing gears? 2.some sort of Shaking Rings noise from Engine , was it really mean that the...

    The transmission consists chain sprocket assembly, with the smaller sprocket on the engine & a larger one at the rear wheel. The chain stretches and the sprocket teeh keeps getting worn whenever you accellerate or use the engine as a brake to slow down. This play can increase up to 2 inch,. thus on lower gear, higher mechanical advantage, looses since the sprocket of the engine transfers power after that play/gap/time required to tranfer the same power to the rear sprocket result of metal on metal hammer.
    Tighten chain at regular intervals and change the chain sprocket if its still the original one. If the bike runs 50+ km in a day and/or at high speed, change the engine oil every 500 to 750 km running i.e. once a month. Whichever comes first. The oil becomes darker & looses it's viscocity(thin). Also after covering so many kms, if the engine oil had been low for that period & running at a good speed you might require a change of piston rings( 1 oversize) and then filed to fit without jamming the piston.........sodeep
