Andy, you are spot on.

I have been in touch with Russell and he is going to dig the mould out and take some measurements, it really would be the perfect kit for the bike so probably worth waiting (and saving) to get.

The hardest bit would be getting the rear pipes out of the seat unit, but I am sure anything is possible (but uaully expensive).

Even the tyga kit is quite close against the carbs on the side so something wider would be better, narrower would definately cause problems.
