Howdy. What is the max. for streetable, reliable output on one of these engines? How are you achieving it? I own an oldie. 98 SRAD. On a slight downhill with 0 headwind I can see 277 km/hr. The return on the uphill simply defeats the power. Lucky to see 240. No mods except drilling the crap out of the internal wall on the stock silencer. How are you guys getting big reliable power? Thanks.
