Brief tips and hints

Hopefully I'll be putting lots more up here soon.... but there's lots more already on the GF250 Page.   Meanwhile here's a link (*G*) to a chain data site in Japan which gives specs on the GF250 camchain: interestingly it's the same as the GSX400! and the same, except for length, as the GSXR750. Surely it should be under less load in a 250, but maybe higher revs might cause just as high wear rate?

And here's one for the drive-chain - there's a couple of models that use the same:

And finally, their rear sprocket page - they seem to make lots of things for many companies :
