BUT adjusted like that there's a tight spot with 0mm. The green new chain required gauge on swinging arm tells me there's plenty of life left in the O ring chain. I've done approx 7K miles and chain wasn't new when I got the bike about 15 months ago. The sprockets are not BADLY worn. I fitted a Scottoiler 7 or 8 hundred miles ago..........Do you folks think I need a new chain and sprockets? This tight spot has only very recently become evident - don't think I've damaged the chain but maybe I have. Think I'm talking myself into new chain here!..............Anyone got advice about cheap/good value UK suppliers? Could do the job myself I thinkIf the tight spot is bad enough you will need to replace. And you MUST do it as a set...chain and sprockets. It is a waste of money to just replace the chain because the worn sprockets will wear it out in no time. And do not cheap out on the chain. Make sure you get a good quality O or X- Ring chain. I know the popular thing to do with sprockets is to get Aluminum to save weight, but I'd get the steel. It may weigh more but it will last twice as long. Just re-read, if it is adjusted to spec and the tight spot has no freeplay, yeah, time to replace.,,,

  • Unloosen the bts on the chain cover, remove the cover, loosen the bar for some slack, reposition the chain and reverse the opertaion. Be sure the teeth are going in the correct direction. Tight the chain so a dime will just slip under the chain itself.

First, are you rotating in the correct direction? Second, remember, timing chain tension is held tight by oil pressure on the rear timing chain guide. If the engine is not running, there is nothing there to keep it tight.

Look for some Youtube videos on this repair. If I remember correctly the links on this chain have different color metal for the spots that the cam tooth goes against. When each side is in the proper tooth the right and left colored links will be on the cam mark and the crank mark should be on the timing TDC mark. Sounds like the slack you describe is wrong and a tooth is off because the tensioner is allowing slack.. You need to slip a tooth one way or the other until the tensioner has room to be in a neutral position.

How much slack should the timing chain have on a 2006 Harley 1200 XL Sportster?


The xl has no timing chain. I'm guessing you're asking about the primary chain on the left side of the engine. I believe it should be adjusted to 3/8 to 1/2 inch at the tightest spot. To find the tight spot, rotate the rear wheel in gear with the spark plugs out.

How to fix my alighnment


Provided you have not been in an accident that has bent your frame,upper and lower triple tree, or forks, the only alignment you can make is to adjust your chain. If the the front wheel is not tracking with the back wheel you just have an improperly adjusted chain. On each side of the swing arm by the rear axle are two chain adjuster cam/wheels. The have numbered bump/stops. Both chain adjusters should be set in the same numbered bump/stop to align the front and rear chain sprockets and the front and rear wheel tracking. the adjusters are on the machine for the purpose of setting the amount of chain slack. Your chain should not be too tight or too loose. If you grab your chain in the middle and push it up and down, you should have a slack measurement of 1 1/4 inches from the bottom edge of the chain to the top edge of the chain. If the setting is off the best way to make the adjustment is to raise the rear wheel off of the ground. A race bike stand is very helpful for this and oiling and caring for your chain. Harbor freight tools sells a cheap rear stand for about $35 (buy the cheaper one piece non-collapseable stand). Pull out the cotter pin, loosen the axle bolt, turn both adjusters till you have the correct amount of slack and they are both set to the same number. Tighten the axle and recheck the slack. If you notice when spinning the rear wheel that the chain goes tight then slack, you have a stretched section of chain. If this is the case you should replace the chain and any worn sprockets at this time.

I need to tighten my chain on my fzr 1000,its a 1987


The first step is to find the tightest part of the chain. Unless it's a brand new chain it will have a tight spot somewhere on it. It's easiest to do this with the bike on a race stand if you have it. Rotate the wheel and observe the lower part of the chain and watch it lift up when you hit tight spots. The spot where the chain lifts highest is the tightest part of the chain. Once you have found this spot, grab the chain on the low side under the swingarm and move it up and down. It should move up and down around 30-35mm or so, or an inch and a bit if you're an imperialist :) If the chain moves more or less than this then it needs to be adjusted.

To adjust the chain, you need to loosen the axle first. Don't take the nut off but it has to be loose enough to undo by hand. Using 2 spanners, unlock the lock nuts on the end of the swingarm and wind the nut in or out until you get the correct amount of chain slack. always do the sprocket side (left side) first, then repeat the same on the other side. Check the chain adjuster marks to make sure that the adjusters are equal on both sides, this will make sure your rear wheel is aligned properly.

Once you have adjusted the chain, tighten the rear axle and check again. The chain slack will change slightly after you tighten the axle, it might go tighter, it might go looser. Depends on the bike. But the chain slack must be correct with the axle tightened. A bit of practise here and you will be able to guess the correct amount before tightening the rear axle.

Once you have the slack set correctly and the axle is tight, make sure to tighten the adjusters. Tighten the front nut first against the swingarm plate so it can't move. Do it tight but not crazy tight. Then holding the first nut so it can't move tighten the locknut against the first nut. Repeat this on both sides.

If you are not quite sure if the chain is right, always err on the side of making it too loose rather than too tight. Running your chain too tight can destroy your output shaft bearing. It's only about $30 or so for a new one but your engine needs to be completely stripped down to replace it, it's not a fun job. I have seen a lot of FZs and FZRs have this problem because people ran chains too tight. If your chain really is too loose then it will start making your gear changes harder to do, that's the sign you need to tighten it.
