If I were to do it again, I think I would go with the OS 1.6 or a Moki 1.8. I love the feel, sound and consistency of the Saito, but I am a bit vertically challenged. Mind you I am not getting the RPM readings that a lot of the others are getting from the 1.8. I have about 5 gal. through it now and it does get better (I think) with each run, but IMO it needs more. I am also not running the 25% - 30% Nitro others are either.

I had problems leaning out when vertical and inverted so I mounted a Cline, cleaned it right up!
