Sprockets

[Carl Howell]

My sprockets are knackered (I think they are 'hooked' and its making the chain go tight) but as my bike is fairly rare (Yamaha FZX250) no one makes aftermarket sprockets and I may have to wait a while to get some from Japan and it will cost loads.

I'm thinking of getting some made (I think I read on another forum about someone who had some made). Anyone know where I can get it done and how much? I think I will probably get a front to fit but will be stuck for a rear. I may drop the sprocket off at a bike shop near me and see if they can find one to match.

Also I may put a few teeth on the back or drop a few off the front as I've figured it out and top gear is good for 150mph+ on the limiter. It's a 250 and will only just do the ton but I don't want to be redlining at 70 down the motorway. At the moment top gear is 1000 rpm above the speed (70mph is 8000rpm, 80mph 9000 etc. Redline is 15,000.

Thanks, Carl
