Hi all, sorry it was late when I wrote...
as for the engine it a 4 cylinder,OHC, in line, 1000cc air cooled ....
Piper cams were the one's who wanted £1,500 plus the tax and post and I'm sure Kent cams won't do it as a one-off....
if the price was right I'd buy 2 units.....
perhaps should have said it has slipper type cam followers......
thanks clogs........
