Title: Rebore and cranckshaft services
Post by: SUPERGRUMPS on 13 November, 2017, 14:06:35
Hi, can anyone recommend a specialist company that can do rebores (and supply new piston) as well as crankshaft grinding etc. for a c15 engine

I used Draganfly as the supplier for pistons for both my B31 and Ariel 350. The bore for the B31 I had done at a local engineering firm (since gone under after nearly 100 years  :-\  ). The Ariel barrel was done by Draganfly. They charged only 35 quid for that whereas the engineering firm was 75.
I had thought that the Ariel barrel needed sleeving as it was badly scored but they checked it and rang back with the good (ie cheaper) news.
I sent the barrel by post to Draganfly. I forget the cost but Im sure it was well under 20 quid. The expensive bit was collecting it as I was in the area - I finished up blowing over 400 quid on some nice new panniers etc for my AJS 650  ::)
