Yes, i heard all the BS old tales, they are totally non streetable, soft on the bottom end, load up in traffic, low on torque. Non of this was true in my experience. cold start i give it one full throttle pump then hit the button. Fires right up and practically idles on its own. Once warmed up idle at 13.5-14.0 on the wideband, cruises at 14.5. Plugs stay clean and is so streetable most wouldn't believe it. No hiccups or stumbles on full throttle jabs. I run 2 small 750 BLP/Thumpercarbs on a 511.
