If anyone has a 13T in the garage and want to sell it give me a pm? I fugured I would check before I ordered one. I want to see how that ratio feels before I spend the money on rear sprocket and chain.

 

Buy a 13 for a few bucks, if you don't like it your not out much

 

I figured I'd check to see if anyone had one around before I ordered one. I should just get a 48 for the back and new chain but it's hard to justify when I only have 500 miles on the current one.

 

I hear you RU2112SH, but you will be glad you did. Most of us have that stock chain hanging somewhere in our garage. Mine had about 500 miles on it as well. It seems like a waste, and I guess it is, but you will really like the better bottom end with the the higher ratio.

 

Definetly need the lower gearing I bit it real bad with the stock gearing on a hill climb at a local pit. I'll be ordering a 48 or 49 I'm just not sure which because I still need the bike to be able to go 60 - 65 on short highway runs to the local trails.

 

It will still do 60-65 with the lower gearing. You just wouldn't want to run that way for 50 miles or anything.

I went with the 13/45 setup like many others here. That yields a ratio of 3.46, which is right in the middle of what you would get with a 14/48 (3.43) or a 14/49 (3.5). With that setup, my RPMs are just about 1000 higher than my speed. That is to say, at 50mph, I am pulling about 6000rpm, at 60mph, I am running about 7000rpm. At 70mph, it is running about 8000rpm (maybe a little higher).

I ended up deciding to drop back to my 14/45 setup because I unfortunately do a lot more highway than I do dirt. When I know that I am going to be on dirt for a while (like this weekend at Apalachicola), I throw the 13 back on the front. Now that Kawi Wawi has taught us all how to break a chain with vice grip and an hex wrench, it's no big deal to swap the front sprocket.

Anyway, good luck with your decision.

 

You know I'm glad we revisited this, I got a 13 for my bike in the beginning, but I had to get the local machine shop make a spacer for it because it didn't have a shoulder on it. Has anyone found a replacement that has the spacer built in, and perhaps even with the noise and vibration dampener? Anyone? Part numbers? My parts guy still has a puzzled look when I ask for parts for the bike.[:@]

 

I want to go with a 14-48 set up, anybody know off hand what length chain I would need. Also, for my mountain bike I buy a chain and then shorten it a few links as needed, can this be done with motorcycle chains with the proper tool or do you have to buy it in that length???

I can get deals on Sunline products but the chain only comes in a 120 length, and what does the 520mean? SL-1 O-Ring Chain 520 /120 Links. http://www.sunlineracing.com/product...p;type=product

I have had the bike since April and no mod's, now that I have somewhat learned how to ride the bike it is time to make some changes, mine is still completely stock. I am afraid to do anything but ride it, hopefully it will come with time. I honestly have to say I know nothing about motorcycles and most of what you guys say goes right over my head. I started writting some info down and bringing it to a shop and they are happy to help me get started on juicing this thing up a little.

Although I do not say much or have much input, thanks guys for everything you post. I am sure it will make sense to me soon.

I don't know about shortening a chain because I have never done it. But the 520 is the width. Most chains and sprockets for motorcyclescome in 520, 525, or 530 widths. You need to stick to a 520 for the weight savings over the wider heaver chains. You can't interchange different size chains and sprockets.
