a 520 doesnt give more torque, the -1 too on the sprocket n adding teeth on the rear sprocket does that. It changes the gear ratio. All the 520 is less rotating mass, but the majority of us wont feel the difference it gives w/o the gearing change with it.

 

hey somewhat related question. I bought my bike used a while back and dont know how many miles the chain has on it. Any advice for how to tell when the chain/sprockets need to be replaced?

 

Read this. Good write up on chains:

Just remember, when you change your gearing the speedo won't be correct anymore.

 

Alright here is what I'm looking at

-jt 520 rear conversion.
-jt 520 front countershaft
-DID 520x110 link super roller chain
Or!!
Ek 520x110link STD chain ( o-ring chain)
Let me know if that's a good or bad set up for my basic riding around town?

 

Pinoyisme,
For "basic riding around town" there's really no reason to do the 520 conversion, unless you really want to. Stock 525 would be sufficient...& is typically cheaper. The choice is yours though. Either of those options you list for sprockets & chain are ok.

Will you be doing your own install?

 

I stay away from o-ring chains. A cheap RK standard chain will last twice as long. 108 is the stock number chain links and also works if you go down one tooth in the front. I just replaced a aluminum 47 tooth rear sprocket that came on mine, it was junk. Stick to a steel one and 45 tooth if you want your speedo to stay close to being correct.

 

hmm ok, thanks Gotcbr. I do get up and going at times when im with my biker buddies doing a Poker run, or maybe a bike ride to see an event lately. But thats about it no racing or stuff like that.

But, i Plan on doing it my self. I have changed my dirt bike chain and front sproket before. i wouldnt imagine that the rear sproket would be hard to change out. The original owner gave me a rear wheel stand with it.

"108 is the stock number of chain links"- i know it is, but idk why i cant find a "108" chain, so i thought if i got the 110, i could take a link out. Also, My bike right now is 1 tooth down in the front.

 

Sure, glad to help.

The install is really easy if you have the proper tools. I change my chain & sprockets almost exactly as "Incognito" does in his tutorial (its a sticky). W/ a dremel cut off wheel, a chain break & rivet tool, & a rear stand, you're good to go.

Don't worry about the chain length upon purchase. You can cut it to whatever length you want. From experience, I'll give you a little tip though... Purchase an extra master-link. They are only a few bucks...& if you over-torque your original & ruin it, you'll have a replacement handy. ;-) Its cheap insurance worth having.

I love that new chain & sprocket feel!

Let us know if you need any help.

 

You guys ever find it handy to have offset links for your bikes? When I farmed (used TONS of roller chains of all different kinds all the time), offset links could be extremely helpful. Just wondering.
