If it makes you happy then thats all that matters. But in my opinion this set up won't be very fast even if you ever get it dialed in. I see your from the Portland area. If you ever are out at the dunes during any holiday, come to Coos Bay by Horsfal Camp ground near campsite 107 were everyone races during the big weekends. You will get to see some fast bikes there, several banshees in the 130-160hp range. There are a few R1 conversions that come to play but don't ever line up next the bigger banshees again after the first pass or two. But if a conversion bike is what you want and you got the parts laying around then thats all that matters, but I am guessing its gonna take more time and money to get it complete and ridablle then its worth. If it was me I would part them both out on CL and build a banshee motor. 4mil cubs are pretty cheap these days...JMO. Good Luck!
