Stock Suspension Setup On Street Twin

I am considering getting my stock Street Twin suspension professionally set up. I realise there is only a limited amount of adjustment available, but I do not consider myself the most spirited rider and keen not to add to insurance cost. More a case of wanting it as good as it can be, hopefully less launchy over bumps. I spoke to Road and Race Performance at Meridon Works, explained my aim, they said they would setup for £40 + VAT. Seems reasonable to me, anyone any experience of doing this and/or having work done by Road and Race Performance. I couldn't find them in the workshop review section, and the name is hard to search for as it throws up lots of results!
