Thanks for all the replies guys sorry for late Reply but been laid up in bed with man flu ( the worst kind ) and especially to Robbo for the offer of help

It seems the racing season is putting a long wait for decent services as I've booked the bike it for carb cleaning and set up at Sparklight Racing for beginning April and that was a struggle due to work for race teams.
I think I know now that the springs were fitted badly/wrong as trying to adjust rebound damping is nearly impossible as the screws are so tight which doesn't sound normal so might just get the OE springs put back in.
