ive started my f3 on the choke and let her warm up until the rpm jumped to about 3000. i took it of off the choke and let it run for about 2 min. once ive reved it up once to about 8000 bunch of smoke came out of the front and the sides (smelled like rubber). when i touched the engine it was still cool (about 28*F outside).

i let it cool down for couple of hours and started her up again on choke and she warmed up just fine, after taking the choke off again i reved it up again to about 8000 and she was just fine.

so is this something i should be concerned about???

 

vent tubes touch something hot? nothing really rubber in the front except the tire, vent tubes, along with some other rubber along the motor...

 

i will check her closely tomorrow before the ride.

i hope youre right billet, thx.

 

Could be crud on the exhaust pipes like oil etc.
Also, crud burning of the rad has funky smell too.

 

electrical in the wrong place? short?

 

My bet is a dead kitten on the pipes

 

i do have unwanted cats and kittens in the garage.

that would be nasty.

 

The only thing really hot enough to melt stuff is your exhaust. They have rubber tubes and covers all over the engine because it takes more than 220 degrees to melt that stuff. Look around your exhaust and see if anything happened to be touching it. Most likely it was oil or something. If there as smoke due to a problem, your bike wouldn't run very well.

On top of that, Id look over electrical stuff too, just make sure everything electronic works, no need to tear your bike apart.

 

i just rode for about an hour and everything is running fine. before i left i have checked everything and i didnt find anything that was out of place.

well, it will remain a mystery.
thx guys.

 

This one had me rollin!!!
