Yes Vince the noise is what we seek, at the other end of the rev delights is the off beat idle you can achieve for the series 1 motors, intoxicating, not the fumes, the lumpy idle, the bored 1200 i did had that in spades. Not all rev limiters are the same, actually quite tricky to get right, one feature i did not want in the iis was all rev limiter then all of a sudden no rev limiter ie wimpy HP to back on again full HP at around the 8Krpm, not what you want cranked over in a sweeping road or tight road condition. Programed in a fit for purpose code section that was well able to have a controlled recovery, engine and rider alike. j
