Can't get second gear :(
Posted: Sun Oct 02, 2011 8:36 pm
I've just rebuilt the engine of my KZ1000 M1 (CSR). Rebore, reconditioned crank, new bearings throughout - cost a fortune.
Anyhow ... the engine is back in the frame and just I'm awaiting some (much) thinner shims before I can start it (valve seats had to be recut).
But even before I fire up it looks like I'm going to have some problems with the gearshift mechanism. I can get first gear easily - nice, crisp and positive. It is also just as easy to get back into neutral (green light comes on too). But when I try to get into second it's not having any of it! It feels like something isn't engaging properly.
When I was putting the engine together and checking the gearchange I had some difficulty, felt a bit sticky, but then it just worked all the way through the range and back down again. I thought it just needed some momentum from the input shaft. I didn't replace any of the original mechanism - selector forks are in good shape (only had 20,000 on the engine), and not bent. The selector mechanism seemed fine and I didn't notice anything amiss with the springs which are all original. So ... what's going on here? Any ideas?
Anyone had anything like this happen to them? Is it likely to sort itself once the engine is running? Any ideas gratefully received.

You'd have thought I'd have noticed that when I'd been riding her. In mitigation it's taken me about two years to get around to finishing this rebuild. That's my story and I'm sticking to it.
