Honda-SOHC

I can vouch for S.E.P. and the work they do, although it was 7 or 8 years ago. They used to offer an exchange service for cb750 cranks, complete with rods attached so you didn't have to wait for your own to be sorted (hence the full name Service exchange parts) or you could have your own repaired. I tried both ways for both the bikes I had at the time (same price for both options) the exchange crank was perfect, and the one I had repaired (a cb650 that a mate borrowed and ran out of oil, spun the big end shell in 3 conrods! ) I was convinced it was scrap, but it came back looking like new, can't remember the exact timescale, but it was less than 2 weeks. Other people I have known have used them more recently, and nothing seems to have changed! :)So certainly worth a go in my opinion!
