Aye Steve, is the MM 3½ 'mothballed' or on a plinth in the living room then?

Radial play in the timing sprocket side, main bearing of the mono was 2 - 4mm!

Also vertical movement in the big-end, not much but feelable. I should have run it on SAE50, rather than semi-synth 10 - 40!

Crank away to Slipstream for a strip and price!

I don't think it'll need crowd funding.

Will keep an eye open, but my previous record is not a good one when it comes to obtaining these beasties.
Good health, Bill
