I sent Patrick an email and will hopefully get some pricing on the sprockets. Thanks a lot for the info, it was very helpful! Now if I could only find a new brake lever mount, as mine is busted where the cable adjuster goes. The only brake we can use is the rear, and it isn't the greatest for stopping.

I'll have to look for him, any chance you could get me his email or ebay username? I'd appreciate it if you could.

I just meant it would be cheaper to buy the 428's since we have a chain that should already work. Thanks for the links!

Hey everyone, my dad owns a 74-76 (not sure of the year, blue and white paint) Yamaha TY250 an the sprockets are pretty shot. I've tried looking online for new ones that use the 428 chain, and haven't come up with anything. I did see a European site that stocks sprockets, but uses 520 chain. We recently had to put a new chain on the bike, but had to use a 420 and not a 428, which may or may no be a problem if I order the stock size sprockets. Basically, I was wondering if it would be better to order 520 sprockets and chain instead of using the 420 chain and looking for 428 sprockets. They seem to be hard to find, and since we only use this dirtbike to peddle around on the farm, we'd rather not spend a bunch of money on it. Is there a site I'm missing to order the stock size sprockets? It looks like the part from Yamaha was expensive but is no longer available. Thanks for any help!
