Justin ,
I am 45 this year and got back on the bikes last june , you dont have to ride a bike on the edge just becasue its capable of it. I have a 250 2 banger and will never be able to ride it to its full potential but i enjoy it tremendously. you wont damage your KATO just becasue you are not ringing its neck .
If you hate it and dont enjoy riding it then consider changing over but even though she is in smick condition you are gunna do a crap load of dollars.
Play with the valve springs you have three to choose from and a mapping switch to boot , get Top gear to tame it down for you if you dont know how ....
By the way i thought you rode well on FRIDAY didnt see you three hours behind the main group dont be to hard on yourself
Look at me i get on the pipe but look like a rag flapping around on the seat at least you look in control ..
