Thank you for all the replies and opinions. I think that the line of the exhaust pipes and the 'cigar box' silencer, that appears to be ready to have a hole worn in it by the rear tyre after a Ballaugh's or rural potholes is the main culprit.
Bars are a bit 'sit up', but if the back is dodgy, could be a blessing. The front number plate and naff mudguard, which won't, take the edge of it for me.
However, congratulations to the builder and thanks for posting it on the www.
Cheers, Bill.
