Rear Sprocket Question

[Anonymous]

I want to put a smaller rear sprocket on my GS550. It runs @ about 600rpm @ 65mph. Considering I want to travel up to Moosehead on the 12th, I dont want the bike to be screaming for 2 or 3 hours. Is there any timing issues with a new sprocket? I know I have to get a new chain as well, is there anything I need to know?

Thanks

Might be better to go up a tooth on the front.

would that be easier? Would I get much of a difference that way?

[Billy Ricks]

Going up one on the front would be like going down about 3 on the rear in most cases. Front sprockets are cheaper so if you don't like the results or want to drop cruising rpm some more you can either go back to stock or up even one more if the bike can handle it.

alright thanks very much. I'll give that a shot.

The front sprocket is also easier to change out, as you don't have to pull the rear wheel. I wouldn't buy a new chain, as the chain is the pricey part. Just get a front sprocket, and put it on, if you like it great, if not pull it off. I'll swap sprockets for a night to go drag racing, then swap back. In all it takes about half an hour.

Oh and BTW you'll need a 32mm socket I believe for the nut that holds the spocket on.

I know that the front sprocket size is a 14 Tooth. What would be the best size to go for? 15T 16T or 17T

[lhanscom]

15T, you don't want to go too far with a 550, you won't have enough power to take off with out killing the clutch. Personally I like acceleration, and would probably keep it at 14T, but that's just me.

Do I need a new chain? I'm guessing theres some kind of adjustment that I can make to tighten or loosen the chain to fit the new sprocket. Is it just the sprocket I change?

[lhanscom]

Yes, there's an adjustment, don't change your chain, you may get accelerated wear on the chain, but not much. Since the chain is the pricey part, don't worry about it.

Play with your gearing first and find out what works for you. Then when you figure out the sprocket sizes you want to use get a whole new set.
