I bought a 2010 RC8 a few months ago. When it gets hot outside (24 degrees C/ 75F) and the engine is fully warmed up the bike will not rev past around 7000 RPM it just bogs out. You then go to the next gear and it will accelerate again to 7000ish and bog out. I live in Calgary so our summer weather is gone and the dealer has been unable to diagnose the problem. I took it to the track last week (cool temps 12 degrees C) and it comes out of the corners hard but on the straight although it does not stop at 7000 the upper 8500 plus RPM power is fluffy not really wanting to pull red line. Anybody else experienced anything like this? On a positive note the handling on track was fantastic.
