Finally the NSR Frankenbike is ready to go. stock MC24 engine except for after market spannies, derestricted PGM II. Planning to keep the jetting on the fat side because too lazy to change jets. Track, race use only with a not very fast old geezer in the saddle. My buddy wants to run a mix of 50/50 pump AKI 93 (same as RON98) and avgas (leaded). I'm not sure we need the avgas. any downside to avgas? Thoughts?
I've had people tell me the bike shouldn't be running on avgas when tuned for racing but..... my HRC manual says otherwise. What kind of squish clearance are you running? And you're right, you might not need avgas. There is a big advantage of avgas, its got a long shelf life. _________________ MC28SP, '16 KTM 500EXC, '16 Beta Xtrainer, '07 BMW 1200GS, '96 Ducati 900SS
