Isn't the YS tough to tune and isn't the piping wierd? Not that it would deter me, but I am just curious.
You might want to do a search on the YS 110. Contrary to popular belief, YS engines are not tough to tune. They are just tuned differently, and piping is very straight forward to me. I find tuning an inverted YS much more easier than tuning an inverted Saito or OS. In fact, it takes very little effort to get an inverted YS to run and idle great.
