ok heres my question. what exactly does a 520 conversion mean? whats the difference over whats on the bike stock and what are the benefits.

 

On a 530 chain the '5' designates 5/8" between pins and the '3' is 3/8" sprocket width. The 520 is again 5/8" between pins but 2/8" or 1/4" wide sprockets. So you eliminate mass from the chain and sprockets and that is a good thing. Bad part is you have less sprocket and chain contact area so the parts will wear faster.

 

I`m not disagreein with your choice but for the weight saved is that the only reason to do it?

 

Thats less unsprung weight , right?

 

Ya, less unsprung weight. But it's also less rotational mass. So that means quicker revving and less HP loss through mechanical transmission.

 

Cool , just makin sure

 

cool, thanks for the info. always had that question lurking around in my head.

 

what about changing teeth to get a little more on bottom end, what is a good thing to do? i also heard that it doesnt change top speed, just where the power is delivered.

 

I read that 15 front and 42 on back is suppose to be about the best. If anyone thinks I'm wrong please tell me, like I said thats what I read.

 

I heard the same because other bikes are coming stock with 16 front and 43 rear. I myself have 15t front and I like it but I would like some more pull so i'm gonna try the 42t rear.
