How much would, for example, going from a 42 rear to a 44 rear make a change to the chain adjusted length?
Right now I have this new chain/front sprocket that the previous owner installed, i'm guessing he got too long of a chain (or changed the front teeth count). I'm adjusted to the redzone...I would love more torque, so my easy and cheap solution is change the rear sprocket...I just want to get it ordered right the first time. Do you think a 44 would keep me in the adjusted range? (I have a 42 on there).

How many teeth do you have on your final drive/ and how many links do you have in your chain?

Hi.
You can have a 45 sprocket in the rear without buying a longer chain. The stock chain have 114 links.
If your chain is too long you just cut some links off to get it down to 114 (that is if you have a link that can be opened, or just buy such a link).
Bigger rear sprocket gives a better gearing for play!!

Finally got around to it...now the final drive has 43 teeth (the big sprocket) and I counted 58 outer links (so thats 116 then eh?).
Isn't the OEM chain supposed to be 114 links?

If I am not totally lacking in memory the stock settings are as follows:
1987-1988: 17/43 - 114
1989-1992: 17/42 - 114
1993-1999: 17/42 - 114
But of course if you want to do stunts you can have bigger rear sprocket (for the lasting of the chain, don't smaller the front sprocket too much) and use a longer chain.

On my '89 someone has fitted a 43 rear sprocket and the chain is standard 114.
But on the '98 it appears to have a standard? 41 rear sprocket and 114 chain.
You can see that the wear indicator is completely wrong now.
I did not check the front spocket, maybe I should.

Ahaha, what is going on there? It looks like the stickers have been moved.
If I move my sticker to the good range (above the double arrow), will that fix my problem?

Almost certainly! I find that moving the goalposts ensures a 100% success rate. It's only the older bike that has been "tinkered" with, the new one is I presume, spot on.
But it does show for you that the chain wasn't changed with the sprocket and does go somewhere to answering your original question?

Do you think he just installed the wrong length chain? Something so obvious shouldn't be lied about when selling something, eh? Although this is America...and wherever he ordered the chain from were probably a bunch of morons, and thats nothing new.

Oh yeah, will going two teeth bigger on the rear sprocket make a difference to the adjusted length?
This may have to be tested by me...
