In the final steps of fitting a 16T sprocket and realizing that this is my first motorcycle, I'm not super certain on setting wheel alignment or chain tension.
Even after reading several threads on it, I'm still a little confused.
I've measured the distance between from the axle bolt to the rear opening and they are near exact, counted the threads to the adjustment but on both sides and they are also the same.

Pics attached show how it looks. Is it alright? Or within spec?
Any help or knowledge is appreciated.

Stock 500F besides the 16T sprocket now. Everything else seems to be original

It looks good to me. I use this alignment tool.

I haven't tried the slack measurement tool

Both also at Amazon and free shipping if bought together.


Hope you like the 16T sprocket. I did.

I recall 35-40mm as proper slack for the 500. Donít make it too tight or you will muck up things.

Ride like your life depends on it.

IMO, I don't think you need to spend $$ on any tool.

About 6 month's ago, I think it was Czeck who simply said that if you measure back from the swingarm center to the center of the axle, and make those two measurements (1 on each side) as close to the same as possible, and have the chain tensioned properly at the same time, you should be fine. This method has worked for years and is very good.

Method 2: IF (and that's a big IF) your original adjustment bolts were properly done prior to your checking (like when the bike was new from factory) you can count the turns of the bolts. I usually take a magic marker and put a dot on one of the flats of the hex, then I count revolutions to loosen them so there is slack (If I were changing the sprocket(S)) and then count back when doing the final adjustments. This assumes that they were correctly adjusted to begin with AND that you can count!! hehehe. Otherwise, if you are simply adjusting the chain and it was OK before, but now just needs adjusting, then just tighten each side the exact number of turns 'till chain tension is back into spec.

I've gone back and adjusted again to give it more slack. I plan to start on a regular interval, measuring the slack since I'm putting 250-350 miles a week on it.

The slack worries me less than rear wheel alignment. I rode it up and down my street and I heard some noise coming from the rear wheel that I'm not sure existed before I messed with anything.

I'll find out later today when the tools arrive if my measurements were good enough to align the rear wheel correctly.
It's also in need of a lot of cleaning. There was a ton of gunk around the front sprocket, cover and chain guard.

The sticker on the swing arm of my bike says the chain slack should be 40mm.

That is roughly what I do.

I have a piece of string with a knot in it. On the right had side of the bike I hold it so that the knot is in the middle of the axle bolt, then stretch the string behind the exhaust to the swing arm axle and mark press my nail into the string in the centre of it.

Holding the string tightly, I move to the left side of the bike and position it with my nail in the middle of the axle bolt. All being well, when stretched back out the knot should be in the middle of the swing arm axle.

Then to double check everything I do it again in reverse, with the knot on the wheel axle on the left side, then stretching it from the swing arm axle on the right side.

That all said, a version of the tool ExTex linked to is only £5 on Amazon U.K., so I think I will get one just for occasional verification.

When using the Motion Pro chain alignment tool,
be sure that the tool is clamped on the rear sprocket evenly.
There may be a lip on the sprocket (rear side ?) and the clamp can be part-on / part-off that lip.


Ride safely,

If you now have a noise that wasn't there before, I'm guessing its too tight.
Had the same happen to me.
Changed the back tire and decided to adjust the slack at the same time.
Then a new noise showed up.
Loosed up the chain - noise gone.

I've now ridden to work twice on it. If anything I feel like the chain has too much slack, but pulling the chain on the rear sprocket it barely moves.
I'll recheck today both using a tape measure and the slack setter tool.
