      Thanks F34R. Hopefully I'll get it painted and back together one of these days.

      Slammin, I've got an M90 hiding out in my shed if you want it.

          More responsive than M1.3? Any specific reason why?

            M90s have flat topped pistons as well, as opposed to dished in B34s, but, let not this be confused with the "dirty" euro B34 which got piano topped, high compression pistons.

              They just feel quite a bit different. Looser and less controlled maybe... The L-Jet wants to go and the M1.3 feels like it's being held back.
