Chain and sprockets

[nzspokes]

I worked out that the change in gearing drops the revs to 6630 at 100 from 7000. She comes on to power about 6000 and pull through 9000 so I think it will be fine.

Stock it must be about 5500 at 100.

Just gotta save up for it now. It will keep going for a bit, cant get much worse.

take the OLD rear sprocket into an engineering shop ... he should be able to make a new one (or three for later) for you.

Ask at more than one place though ...

Easy yes, cheap no. Some sprocket blanks can cost more than items from a bike shop. Then there's cost of boring and drilling.. And that's only rear sprockets, fronts need splines cut. More $$..

Well its all done now. Amazing the difference it made to the bike.
