I had Mike fit the full monty on my last Gen 1. This combined with a change on sprocket, (cant remember which - only did it because my supplier couldnt get hold of a standard fitment sprockets at the time) made a hige difference. It would easily lift the front on the throttle in 1st and in 2nd with a little more encouragement.
I now have another Gen 1 which has the slip on kit fitted. It doesn't seem anywhere near as lively off the throttle as my old one. 
The full monty imho completely changes the power delivery / lower down torque from standard. It felt like a completely different bike after Mike waved his wand over it.
How much to change up from a slip on to a full monty please? When are you coming back Mike?
