525 rear sprocket wanted

[mjl3truck]

I'm looking for a place to get a 525 pitch rear sprocket for a Gen I.
Seem to be having trouble can find 520 and 530 but not 525.
I picked up a project bike that had Core Moto wheels and the guy swapped the chain size but I didn't get the wheels with the bike.
Thanks

You might find it easier to switch back to the 530 chain where you will find a myriad of chains and sprockets....525 is an odd-ball size.

Thanks for the reply, I agree, but I bought this thing as a pig in a poke and I'm working my way through it as cheap as possible until I figure out if it is ok then I'll start throwing money at it. Currently it has a 525 chain and front sprocket with a 530 rear.
1) does it start, yes
2) check oil pressure, good
3) drain oil and cut open filter look for chunks, all good
4) Next step is to make sure it has all 6 gears, if it does I'll continue to work my way through it budgeting for the 530 stuff if everything else is good.

I stand corrected, there are a whole pile here:

Amazon.com : 525 rear sprocket

There's a truck load on eBay as well... (hayabusa 525 rear sprocket)

Not really an old ball size, just not used on a Busa
It is on many other bikes

So the bike has core moto wheels?
If so you need sprocket for the after market wheels, the bolt pattern is different

I've owned mostly Suzuki bikes and have never owned on with that pitch...

Always good to learn one thing each day...

No the bike had Core Moto wheels but I elected not to buy them as this Gen I project is a cheapo I have a Gen II that sucks all my money.

Thanks everybody for the replies.

So the ebay and Amazon ones are just 530 sprockets, I don't know why they have them listed as 525 also. If you look up the Vortex part numbers they are giving they are 530s. Catfishin' I guess.
So.... I pulled the chain off my Gen II dropped a couple links put it on the Gen I with the 525 front and the 530 rear sprockets rode the Gen I for about 5 miles to check to make sure it had all 6 gears, yes. Now I'll just get a 530 front sprocket for the Gen I be done with it and won't feel too bad about doing a 520 conversion on my Gen II.
