Hey Guys... had an interesting problem this morning with my bike 06 CBR600RR. When i turned her over, she started fine straight away, but then this brown smoke started coming out from the front of the bike and there was an odd burning odor, i quickly pulled my helmet off and jumped off the bike to try and see specifically where it was coming from, but couldnt work it out. Odd thing is... it only lasted about 60 seconds or so, then stopped. I rode the bike to work this morning, and it felt fine, made no odd noises, no more smells, nothing. Any ideas ? Could something have leaked onto the engine and it was burning off ? Is there anything i can easily check myself ? What does brown smoke usually indicate ? Cheers guys.
