Sprockets - 2/28/2005 6:52:15 PM    PiMpBlueF2   Posts: 40 Joined: 2/4/2005 Status: offline hey guys, i have a 520 conversion kit on my bike, i kno for sure it is 1 down in the front, but unknowingly i replaced the rear sprocket with a stock sprocket, what is the stock number of teeth for the rear sprocket, because i GOTTTA get a couple more teeth up so i can pull it up a lil easier. Also, Would i have to get a new chain if i were to replace my rear sprocket with 2 or 3 teeth increase in the back?? because my chain is new already and that would suck to have to buy another one Post #: 1

Only, I have a 1990 F1 (but no one posts on the f1 forum), and my chain just broke on the highway (scary!) and I had 2 quesitons. 1. the front sprocket reads 520 while the chain is a 530. The front sprocket is also a 14 tooth, while I thought the stock sprocket is 15. I'm assuming someone switched it out, and didn't replace the chain... ? Safe assumption right? Could this attribute the chain breaking? When I buy a chain now, should I buy a 520 and buy a 520 rear sprocket too? Also, Should the front sprocket have some play, and be able to wiggle back and forth a lil' bit. I'm talking side to side, not front to back play. It's maybe a millimeter in play. It's enough play to make me think there could be something wrong? What should I do? THanks! (in reply to CBRFRENZIE) Post #: 5

The 530 chain on a 520 sprocket would REALLY cause me to worry. As you prolly have heard, sprockets and chains should be replaced as a set. So decide what ya like best, 520 or 530, and change the whole thing. _____________________________ It's better to burn out ... Than high side! (in reply to tims626turbo) Post #: 6

RE: Sprockets - 3/6/2005 9:25:43 PM    tims626turbo   Posts: 8 Joined: 10/6/2004 Status: offline I'm probably not going to replace the front sprocket since it's a sunstar aftermarket. But If I need to, I'll think about changing the rear to match the 520 set then. So, should I order a rear sprocket or something? What woudl you do in my situation? I'd prob. keep the same ratio though, cause I kinda of like the ratio, I wanna be able to wheelie more, (or at all) but I'm already at like.. 7k on the highway, so I don't wanna drop my ratio anymore cause it'd effect my MPG too much. What would you guys do?! ANd where can I get nice sprockets? thanx! (in reply to chainstretcher) Post #: 7

Get it??) The manufacturer is after as much strength and as little weight as possible, so the 530; which was the standard for a long time, was being replaced by the 525 ( following the theme here??) SO....A 520 is a lighter chain than a 525, which is why race bikes have 520 chain conversions!! The 520 is more common than a 525 since people tend to go for the lighter is better syndrome, but lighter will usually wear out quicker unless you spend super dooper bucks for a HIGH TENSILE STRENGTH chain ( some of these chains are $200!!) You will not notice the difference either way...just F.Y.I. (in reply to tims626turbo) Post #: 8
