Thanks, but it already revs like mad and for it's size it is quite powerful. The main problem is that it is just a small bike and I tend to thrash it a bit too hard. When it was my main bike I used to wreck the big ends by riding it flat out all the time. They are a lovely bike to ride on country lanes, I think I just wish they had made a 500+ version of it because then it would be my perfect bike.
I think I have now decided to get the MOT up to date, ride it for a bit and then if I still find it too small, put it up for sale and see what it fetches and put the funds into my T100 fund, unless a cheap 500t engine turns up, then....out with the hacksaw and welder....
