Nope, no more boost bottle (as if that was the only reason to ditch that turd bomb).
benefits are better low end, better throttle response, easier jetting, easier to diagnose engine problems, cleaner engine compartment, less mainenance, no more sync'ing...
Draw backs are slightly less top end.
Trinity makes one. Personally I prefer the old Graydon ones, but they went out of biz. You can still find them on ebay tho or do what I did and make ur own.
