Hi there and thanks for you responses.
Star Twin, don’t sell your Velocette, everyone should have one!
I sent an email to SRM with the above pictures to see if what I had was scrap and unworthy of getting reworked, and should I seek better second hand to get reworked?
This was Geoff Dewhurst’s response:
Hi Kevin,
Thanks for your enquiry, the strap across the crankcases does not scrap them and is often seen broken from a rod breakage or just brutal treatment, one thing I have noticed is the two drillings above the idler gear and the crank pinion, these are not standard and is something that is done during the needle roller conversion there is also a Job no of what looks like F54 so maybe it has been converted by a company called Devimead before 1987, as we bought them out at this time but do not have their records. You can check by looking to see if a block of alloy has been welded to the inner timing cover below where the points would sit, if so this is the oilway to feed down the end of the crankshaft.
The cylinders should not be a problem to repair, and to fit liners to take it back to standard bore size.
Hope this is good news.
Regards Geoff
I am very happy with this. I know he’s only going off pictures, but I am sure he has seen some right basket cases.
I hope the bottom end isn’t too terrible when I take it to bits at the weekend!
Kevin
