I think I may phone them Monday.
I sent them 4 cranks, as the two they were rebuilding. they said need some webs. so they used the webs off the spare cranks I sent them.
both cranks had new centre shafts.
so £187 each crank+£70 new centre shaft= £260x2 =£520 +£50 as he said they charge £25 for each of spare cranks to split them down.
I would say they have made a mistake.

I've stripped it down checked the teeth on the clutch basket gear, crank seems fine etc etc the only thing I've found is I'm a clutch plate missing. I've rebuilt it but I'm waiting for my f3 valves and clutch parts to arrive and I'm also having a go at machining some S power valves for the centre ports.
The power valves were all set up wrongly too so I'm hoping she goes a bit better when rebuilt.

Yep that's the same as on the AR125, the hidden Cush drive can wear allowing movement and a 'clattering' noise when ticking over. The noise goes away when the revs pick up / under load500bernie wrote:Is the primary fixed directly to the back of the basket?
On Kawasaki triples they are riveted together with a hidden cush drive between the two parts that can cause some nasty noises when worn.
If it takes more than 2strokes then your just playing at it..

I did that once, and this isn't the same.Howie wrote:Bit of a long shot but have you checked your balancer gear is aligned with the crankshaft gear?
the balance wrong by 1 teeth makes the bike unridable and actualy turns the hole bike into a vibrating plate
My ultimate goal is to die young as late as possible !
