Re: Twin carbs on some big singles ..why?
I had an old XT500 (and my dad had an SR500) both of which ran just fine on traditional single 'slider' carbs, and I was surprised when the simply gorgeous SRX600 was released with twin carbs: one 'slider' plus one 'CV' vacuum carb.
I remember reading something about the different characteristics of the two types of carb balancing out engine response/performance from tickover through the midrange etc.?
Not a particularly scientific answer, but your post struck a chord...
p.s. another interesting point: my Enfield Bullet 500 carries an exact copy of the carb which I used to have on a TS250 Suzuki (Mikarb/Mikuni VM28 )
