I bought a used 00 426 on the 17 of Feb (yesterday). I started up, and after 2 minutes the exhaust pipe turned into glowing red, like lava from a volcano. The engine would not idle, and when i was driving the bike is was not running very well. What is the problem? Is it something wrong with the ignition and have i done som serious damage by running it like this. I was running it for 30 minutes. Help.
