Thanks for the reply Goff.Ive now sorted it,they were splined & banged into the ends of the bars then rusted up a bit hense the need to be a bit more aggressive .I just had to replace the solenoid on the bottom of the lower tank, what a job!!!I found a novel way of avoiding having to strip of the top tank & & pulling the bike to bits to do it so if ever you need to just get in touch.
Regards Bikerman
