I paid a visit to Frost's tuning place in Ipswich today, just to see what tuning my bike-carb'd x-flow would cost, and what I could expect as a result. He told me "3 to 4 hours, £200 - £250" which is pretty much what I expected, considering the effort involved with the continual dismantling & rebuilding of 4 carbs every time you want to change the jets.

The only thing is - I only heard of him from this forum a few weeks ago, and I have no idea of his reputation.

Can anyone advise?

Well at Boggs i paid nothing like that
