Topic: 520 spockets for CB500/550

[TerryK]

Anyone have a source for 520 conversion sprockets for the 500/550s?

[TerryK]

Anyone?

Rears can be thinned on a lathe.
Fronts are tougher, can be turned, but they are fairly hard.
 Could he ground by handheld grinder if you do one side at a time.
 However, buy the front if you can, i suspect some fronts may be softer than original , after you remove required amount..

Yeah I know about SS, was just wondering if anyone made an affordable kit. Thanks.

I think some of the XR series hondas had a 520 sprocket that will fit the front of the 500/550.  If it isn't an XR then it is definately a Honda dirtbike, it has been a little while.

My 83 XL600R uses the same countershaft sprocket in a 520 as my 74 CB550 as well as my CB350 and CB450 vintage racers. I have a complete set of 520 sprockets, front and rear, for both racers from Sprocket Specialists.

I'm going through this same process. I bought a 520 front sprocket from Sprocket Specialists, part # 5033-17. I couldn't find a 520 steel rear sprocket anywhere, only expensive aluminum ones that probably wear quickly. So I ordered a steel 530 rear sprocket from JT Sprockets and will get it machined down to the correct thickness.

[xtravbx]

I think that's the route I will be going. I can't find the rear, even the aluminum ones. Ive found the fronts from a few sources. What's the point in only selling the front??

What's wrong with getting a 530 sprocket? Not trying to start a fire here, just wondering what yall are trying to save by converting to the harder to find 520 size when the 530 size is readily available.

Can't run 530 o-ring or x-ring without risk of damaging the cases.
520 is narrower and the o-ring/x-ring version is case safe.

Ohh, yeah I forgot about the 520 o-ring chains. It makes sense, but so why not just buy a standard 530 roller chain? Sure it may not last as long as an o-ring chain, but we're only talking a few hundred miles here, and the standard chains are cheaper too.

Not only a few hundred miles, my 650 had a factory o-ring chain, I have fitted it with an x-ring, and it goes about 5000 miles between needing adjusting.  With only a squirt of lube every week or so when I'm using it heavily.  I would like to see a standard chain come anywhere close to that.

Well that's because you're using synthetic oil in the engine. Synthetic engine oil will make that standard chains last forever too. Even in dusty conditions.

I started out using synthetic oil, made the popcorn taste like #$%*
