Alright so for like the last month or so my bike doesnt have any top end power for the first 20 mins while im riding. If i just jump on the bike and try and go full throttle when i hit 10k rpms with %100 percent throttle it just stops accelerating. The engine is still going but the rpms dont go up however if i give it like 75% throttle then it accelerates. Eventually this becomes less and less of a problem as i "warm up" the bike however this has never happened before and there has to be something causing it. Anyone have similar problems or any idea what it might be? Anything would be greatly appreciated.
