If you use cheap oil and/or don't change it often enough, you'll end up with links in the cam chain binding up.  That can eventually lead to the the chain skipping, which event can range from making the bike start hard and run poorly to scattering debris over 100 yards of race track. 

 

It's a race bike, not a toaster.  You have to maintain it.

The stock muffler inhibits top end because the tip necks down too quickly (a noise reduction trick).  Any good quality slip-on will correct that. 

 

The off-idle throttle response is somewhat abrupt.  Injectioneering does a mod to correct this.

 

Get a GYT-R tuner and try the Jay Marmont map.

 

The bike is extraordinarily sensitive to suspension adjustments.  Play with the sag at around 105-115.  Pull the forks up about 5.

Can you translate your question?  The GYT-R tuner doesn't stay on the bike, and I have no idea what "pc5" means.

Pc5 is a piggyback fuel comp made by dynojet. You can adjust with a laptop or install a botch o2 sensor and run a mode that is auto tune. For what it's worth in a non heavily moded bike the gytr tunner is all you need. IMO.

With the '10 at least, there was nothing wrong with the header at all. But the end of stock pipe has an abrupt reduction in diameter that brings the engine up short at top end. Most any well made slip-on will correct it. No reason to spring for the whole system.
