Its madness that they are so expensive to rebuild!! I'm dreading mine going when it does! Think the rgv cost me £200 to rebuild, all new parts bar the l/h outer web. And got a brand new lc crank with tz rods and bearings for £220 brand spankers!
Bloody honda! Dont start me on nc30 spark plugs either... argh!
On another note, might be worth trying pj engineering in Wolverhampton for a rebuild but the scousers (Grampian) are pretty much the same..
