I recently had a new tire put on my bike and they told me my chain was stretched and needed to be replaced....so i was trying to figure out what all the different sizes actually mean to my ridability... i hear a lot of people say use a 15 on the front...
1. but what does that change over a 14?
2. and then what does a 520 on the back do as opposed to a 525?
3. whats the difference in adding more teeth on the back 39, 41, or 46... i was looking at this sprocket.....

any help would be much appreciated...or i will probably just go out and by whatever and get rolled up by zombies

Your M900 should already have a 520 chain. The 525 is heavier and more expensive as well as being unnecessary for that bike.
The 14T front sprocket changes the angle of the chain, and IMO the only downside is that it wears the chain rubbing block more quickly. Some people have had the chain saw into the swing arm.
Adding teeth to the rear is the same as reducing teeth in the front except you have to add more to get the same effect. I run 15/41 on my 96 and like it a lot. Your 99 has different primary gearing and different ratios in the transmission so you may want to consider going to a 42.
Check out www.gearingcommander.com (//http://)
A larger front sprocket lets you set up the bike with more swingarm angle and you can get on the gas earlier coming out of corners. For sporting purposes, go 15 and 41+. For commuting, go 14 and 41+. For touring, go 15 and 41 -.
To determine the ratio, devide the rear # of teeth by the front #. The higher (or bigger) the gear ratio, the faster you'll accelerate but the more fuel you'll use because of higher RPMs for the same speed.
So if i buy a 15 front sprocket and 43 rear sprcket how do i determine the length of chain needed to make that work?
this is the package i am looking at,t shirts unneccesary but whatev, good deal?

Count the number of links in your current chain. Probably less than 104. buy the kit and see if it is too long. Probably will be. with rear axel approximately 3/4 of the way forward in the adjustment, cut the new chain to fit.
Price doesn't look too bad. A little higher than the last one I bought for my '94 18 months ago.
I've got to admit that it has been a few years, but I bought an RK chain for a CBR1000F, and new steel rear and front, and in less than 3000 miles, it was losing rollers. I sent it back to the distributor, they said they sent it to RK, and the reply I got was that it was attacked by battery acid. I crawled under there, there was no damage to the aluminum swingarm, no damage to the battery box, or frame, no damage to anything, and the battery drain was on the opposite side from the chain, so it was all bullshit. I won't use RK chains anymore because of the kind of customer service. I put a DID ZVM on those same sprockets and it went 25,000 miles more before I sold the bike.
I would get the 120 link chain and cut it to size. Run it as far back in the adjusters as you can, but allow a little room for chain stretch.
