Thanks everyone for the comments,
i agree, I don't think I'll be putting anyone on the back besides my son,
it's surprisingly solid though, but wouldn't like to stress it too much.
With regards to the pipes, I mighten get away with it yet, I'll register
it with mufflers, then change it back & then see what Mr. Plod thinks!
it's not nearly as loud as a Harley though.
The water thing will be trial & error, will have to wait & see.
The seat was in such good nick, & was professionaly made by
someone in the states, it was too good not to put on,
regards, Cus
