Ok guys this might sound stupid and iv read through forums and I know my way around a bike rarely well but my mind just isn't working this time. I have an 05 r6 and I just changed sprocket and chains since they were due. I went to a 46 tooth rear and a new DID chain. both are supposedly 530 pitch. After I adjusted and everything my chain and rear sprocket are binding. Binds in the same spot on the sprocket every 360 degrees. I don't know if its sprocket or chain some ideas or a point in then right direction will be much appreciated any questions you have or anything I left out Just ask away please. Thanks.
Went to 46 since I was looking for more low end power since i do more mountain riding.I did chsinge both sprockets rear is 46 and front is 15. Both vortex sprockets it binds on the same spot of the rear sprocket. No matter where the chain is. And it is a rivot style chain. And by binding I mean the sprocket and when it gets to the point of binding the center of the sprocket teeth grab right on the roller of the chain. Of this makes sense. Almost like a preload on a rear diff. The sprocket has wear on the teeth already where the chain is rubbing. I can try to up load a pic of it helps. Just don't know a real good way to explain it
1. You went the wrong way on the sprocet size. The stock sprocket was 48 teeth. +1 in the rear on a 03-05 and R6S is 49 teeth. The 06 and up R6 had a 45 tooth rear sprocket.
2. Also, the stock chain size is a 532. It sounds like either the chain or the sprocket is 532, and the other is 530. Hopefully you didn't get a 525 sprocket.
Ok so this is where some of my info is wrong of what I thought I knew... What pictures would benefit you and help you understand exactly what I'm dealing with..
Pictures of the sprocket and chain where it binds. A picture of the chain and rear sprocket straight on from the back. And picture/pictures of any numbers on them...or the boxes if you have them
That second pic looks like your chain is WAAY out of alignment. Is the rear tire cocked to one side? Sighting down the chain looks like it takes a left turn.
try to put a tape measure on the swingarm axle (hollow hole in frame) and the rear axle. If you have a couple of long dowels... slide them through each end & use string or long rubber band to bind them and use a tape measure to get an exact dimension. Adjust the axle until you have about 1/2" to 3/4" of slack. If you are heavy... add more slack.
It will get you very very close! Do not trust the swingarm graduation marks.
The gap between teeth and chain is where its binding its like the rollers are starting to ride on the tip of the teeth until they slide down into the pitch. I ran the bike on the stands and the rear tire has a slight bounce to it. Would this be just because I'm not sitting on it putting load on the chain ?
the wheel rotates around a stationary axle, it really cannot have a 'bounce' to the entire wheel unless you have something bent/assembled incorrectly.
it really looks like something is causing your rear sprocket to not align with the front sprocket, do you ahve all the spacers for the wheel in correctly?
As far as I know I do. At least looking at the parts blow up I'm sure I have everything in correctly I did just do rear wheel bearings but I put everything back in the order I took it all off..
Do you have your old chain? Those rollers look thick. If you have the old one, is it original, or an aftermarket? The original is a 532, which has rollers that are about 1mm thicker than a 530. To me, it looks like the chain may be mis-marked. Either that or the sprocket is cut badly?
Cheefa, he said the pic that he posted that showed the sight line down the chain, was with everything loose, not adjusted. Kinda negated what I wanted to see in the pic, so don't base any trouble shooting on that photo
installed front sprocket with lip out. And I don't have the original chain any more. Since iv done this before I thought it wouldn't be a big deal. Only thing I can think of too is if I got a bad chain and or sprocket.
Since it is binding in the same spot on the sprocket every rotation, I suspect the sprocket. Good news is you want a 49 tooth sprocket for what you were going for anyway. The bad news is that you may not have enough chain length since you cut it.
Going down in front, or up in back. Going toward 1:1 ratio (lowering the ratio) increases top speed but reduces torque at the wheel (less acceleration). Raising the ratio increases acceleration. You started at 48:16 (or 3:1). You currently have 46:15 (or 3.06:1), so basically no change. A 48:15 stock rear size and-1 in front is 3.2:1, and the 49:15, -1 in front +1 in back is 3.27:1.
Which ever way you go in front, the opposite way in the rear has the same effect, but it takes about 2 teeth in the rear to equal the effect of one tooth in the front. That's why your current set up has almost no change in gear ratio. The -2 teeth in the rear cancelled out the -1 in the front
