I've heard some bad stories about Bill Smiths at Chester.
I'm a new Suzuki DL650 Vstrom owner having owned only Hondas in recent years,I use Blackpool Honda for servicing who I've found to be fairly priced and great to deal with,they'll also lend you a bike whilst yours is in for work but you need to ask before dropping yours off.
I was quoted £350 for a valve check on my CB500X with a further £100 for adjustment which in fairness has easier access than the Vstrom.
Last big service there on my 2010 NT700 Deauville was £750inc the Very Annoying Tax,that included oil and oil filter,air filter,coolant and brake fluid check,plugs,valve adjustment(screw and locknut not shims)inc new rocker gaskets,rear brake pads and a new pair of tyres.
And here's a LOT of plastics to come off a Deauville before any work is carried out.
Ordinary yearly service is around £180.
I've been dealing with them for four years now and feel I can trust them.
I'm up there on the 28 Dec for pair of tyres on the same bike so I'll ask about the Vstrom.
PS, live a couple of miles from J23 M6 so not that far from you,if you're in Helsby it's a 90/100mile round trip for you.
