Topic: Cb550 sprocket chain conversion options

[jtran000]

Hi All,

I need to change my sprockets and after reading some old posts I'd like to see what others have done.  I know you can mill and mod the stock front to accept a 530 but I too lazy to do that, i'd rather buy a ready made kit.

I want to use an o-ring chain and understand the usual troubles with rubbing of the crankcase.

I've only found a few options online for conversion kits and those are:

- Stay with 530
JT Sprockets 530 17/37T Sprocket & Chain Kit 74-78 Honda CB550

- Change to 520
cognito moto has a front and rear sprocket for 520 conversion and i can get the chain at cost due to my membership at my motorcycle workshop.
aluminum rear - https://cognitomoto.com/products/aluminum-rear-sprocket-for-cb550-520-chain
front - https://cognitomoto.com/products/17-tooth-sprocket-520-chain-for-cb750-cb550-cb500t-1

cost will be about the same if i go either way, ~ 150ish

anybody have any other conversion ideas i can go with?

thanks in advance

Sprocket specialties can do 520 sprockets for you.  They are great

Yeah, i saw that they do conversions as well.  i just wanted to buy it today haha.  I'm so close to finishing this phase of my build and i just want to get things done.

Call them.  They probably have sprockets in stock that fit.  They just belong to other models.

I just called and emailed them for a quote.  Anyone have a ball park price?

[innovativems]

I think mine were $75 for both.  They had them in stock and got them out asap

I was on dotheton searching reading up on what they do over there.  I read that Moto Madness sources their sprockets from Sprocket Special.

Cognito Moto sells them too.

Cognito sells the set for 147 w/o shipping.  I just talked to Lance from Sprockets and ordered a 520 conversion 17t/37t for about 100 shipped priority mail, should be here next wed.  Once installation is complete I'll update my build page. 

I blew a reg/rect last Oct and ended up rebuilding the front end, changed exhaust from 4into4 to a kerker 4into1, rebuilt carbs and a slew of other things haha.  Can't wait to get riding agains as the weather in the SF area finally warming up.

now I need to find a 520 chain

I am thinking of doing this same conversion prior to the 1300 mile ride to Colorado in August.

I just want to note that Cognito's rear sprocket is made out of aluminum for those that care
