I would easily buy that a KR-2 will maintain altitude at 18HP. Mine could maintain altitude at under 1/4 throttle. Hey Mark, next time you are up see what manifold pressure you can maintain altitude at. That will tell us.

Been a lurker for several years now .Haven't surfaced for three or four of them ! I've been sitting on the fence " forever " with regards to power plant selection for the KR . Like every one else , I've watched all types of venders, ideas and trends come , and then go ! About the mid nineties , Hans Mayer ( Contact # 45 , RAA rec flyer May 1996 ) was suggesting the BMW boxer engine with one of his custom belt drives . Heck if I was going to disagree with Hans( !!? ) - but it did seem like quite a stretch . Anyway Hans went on to explain that the KR only needed 18 horses to maintain altitude .( whoa ) Can any one explain this ? Did he mean the KR-1 , or the original KR-2 - at just over 500 lbs ? So why the interest in just two jugs now ? Over the years I've noted that even the most potent F/F installations usually don't result in cruise speeds of much more than 130 to 140 knots ! Mark Langford , ( and every one else ) feel free to jump all over this one ! Now the new R1200S has a claimed 122 hp , and 83 lb-ft with efi .Two thirds of that hp is plenty , and as for the so-so torque - I can think of three different redrives that should fix that ! I do see the potential for more leeway regarding ducting , w / b ....maybe this is worth another look ? _______________________________________ Search the KRnet Archives at http://www.maddyhome.com/krsrch/index.jsp to UNsubscribe from KRnet, send a message to krnet-le...@mylist.net please see other KRnet info at http://www.krnet.org/info.html
