I fear you have damaged chain and sprocket. Adjuster nut must have slipped causing chain to get back to where it was. Oil window black means oil is really old. Please take your bike to Yamaha service center, they will take care of everything.

    Try to readjust chain, this is how its done:

    1. Loosen the rear wheel nut
    2. Adjust the chain by moving the adjuster nuts and when you do keep a check that wheel is in center and chain height is according to your bike manual. If you have the manual or sticker placed near the chain, please check that for accurate level of chain tension.
    3. Tighten the wheel nut.

    Regarding the black oil, if you have not changed the engine oil since long it may be time to change the engine oil. Simply buy a good brand of engine oil, completely drain the oil old and fill new one. If the old oil is too black, you may want to use a engine flush before filling new oil.

    The lower side of chain should be 1/2 inch above the chain liner , this is correct for most bikes. However I'll still suggest to visit Auth. Yamaha Service center as chain is a critical part of bike and you will not like to get stranded on road if something goes wrong. They will not rip you off, all you need to do is shoot a complain email to Yamaha in case you are not satisfied with the service.

    Regarding oil, don't top it if there was no leak or loss of oil. Excess oil can cause harm to engine.

Strange grinding Sound coming from bottom end of engine


If the bike sounds fine on idle and will rev freely then I would suspect the gearbox and particularly the power output shaft/drive shaft

Transmission ?


My first guess is that the gears are engaging, but if it's the original 12 year old clutch, it might not be grabbing.
Pull primary cover, put into first and try to pull forward while someone is watching clutch to see if it's locking up ok.

Grinding noise underneath at the back of tractor while realizing clutch petal trying to move forward or backwards then noise stops while tractor picks speed


No it was a bad clutch pad and the slowing up and down was the clutch pad grabbing at certain spots that still had material and the noise was the clutch scratching as it slipped around the clutch plate and them greasing it could have started a fire from the friction of the plate and pad making contact.

I have a 2000 FXST while riding about 30-35 mph I noticed a swishing sound coming from the bottom end,sounded like the primary chain was making noise.A few miles later sound got louder, almost like...


The primary chain is supposed to have 5/8 to 7/8 inch up and down play in the top run of the chain with the engine cold. I think it's 1/2 to 5/8 inch hot but I've never set the tension on a hot primary chain.

But, if you say you heard a crunching noise, then the engine started running rough and popping out the exhaust, I'd suspect something to do with the ignition timing. The ignition timing is controlled by the pulses from the crank position sensor on the right flywheel.

If I were you, I'd pull the primary cover, take the compensator sprocket, primary chain, and clutch assembly off, pull the rotor and the stator of the alternator. Then pull the sprocket shaft seal out and take a look at the Timken bearing. While you've got everything off, take the plugs out and turn the engine over and feel for any roughness. It may be time for an engine overhaul. I've only seen Timken bearings fail in one Shovelhead engine but they do fail. Hopefully, you'll find something much simplier and less expensive than this wrong.

Good luck

1559 motor makes noises


CHECK everything in the primary, primary chain, adjuster & shoe, all bolts, clutch parts, and very important check alignment of primary chain. If motor was pulled from bike inquire as to if when motor put back if alignment tool was used. Good luck.

Chain problem


I noticed a repetetive whirring coming from somewhere near the front sprocket- Or at least I'm pretty sure that's where it's coming from. It's not quite a grinding but it sounds like some sort of contact problem. I jacked up the bike, and the rear wheel spins freely in neutral except for a small area which seems to need just a *little* more force to spin around. Not sure if it's from the rear wheel or from whatever might be wrong up towards the front. The noise has an accompanying gritty feel, which rather reminds me of a bent rotor rubbing lightly at a certain point once per cycle on the brake pad. No amount of variation of pressure or speed in braking seems to affect the problem. There's no obvious performance issues, and I only hear it when I've got the clutch pulled in (probably because it's not loud enough to hear over the exhaust, not because it isn't happening). I ran the bike downhill in neutral and it still makes this noise. I lubed and adjusted the chain a day or so ago, and the adjustment notches are at the same point on each side. I had also ridden over a set of train rails cut deeply into the road, but I doubt that had much impact on anything. Any ideas?,Sounds like your chain may not have stretched evenly. You also may have it adjusted too tightly. You should always adjust the chain so that you have the specified slack at its tightest point. Do you know how many miles/KMs are on on this chain/sprocket set?,,,
