I have a 2008 Suzuki Intruder (VL250) that is really struggling to run in the cold weather. It stalls and dies, loses power while riding, and dies while waiting at the lights. When I warm it up, even with the choke on full and the idle high, it still chokes and dies after a few minutes. I have to keep the revs up and constantly feed it gas just to make it to my destination.
I suspected a dirty carb, although the funny thing is that it only happens when it is cold. Seems to run fine during the day... only on cold mornings does it behave like this.
Also, the bike has straight pipes installed (with baffles + steel wool). In the past the pipes have not caused any problems, so I do not suspect them. It only happens in the cold weather.
Thanks for your time.
