Thanks for the reply Andy, that was the sort of info I need to help me make a decision, it would be good to hear from Tom as his opinion would be valued, especially with him doing track days and using it to more extremes than riding on the road. I did get in touch with Brook Suspension but they no longer do that type of work. Am I right in thinking that the SE shocks were the same as the SP ones ?
Spud_MC18 I have spoke to Mark at MH Suspension and he is quite happy to rebuild mine, they can replate, anodise, re-gas and replace the internals as required, pricing would obviously depend on general condition although there is a reasonably accurate price for just the overhaul without the cosmetic stuff.

Carl.
