Impossible to tell you what needle without knowing more about the tune of the engine.

You might try RH in it as a starting point, assuming you can find them.

SM's were the 'standard' fitted needle, the RH is a tad fatter. As Hap suggested: Call Joe and have a natter... but have your engine spec's to hand ahead of time. /bcforum/images/%%GRAEMLIN_URL%%/wink.gif
