I find most of your posts...….err, what can I say? entertaining? plus a subconscious dollop of schadenfreude, but quite honestly I can't help wondering (admiring?) why you get yourself into so much faff, effort and hassle just for a little bit more poke. I couldn't be arsed with all the swapping and non-standard experimentation and would simply buy a bike with a bigger engine and go adventuring o'er hill 'n dale.
What is the attraction for you?
