Cold Start

'96 R1100R
Has anyone had an issue with cold starting with lots of fuel smoke, and running rough until about 30 seconds after start up? This has been happening ever since I have owned it for at least 2 years. Seems to be getting worse as time goes on. My feeling is too much air when cold =too much fuel until the engine warms up and things tighten in tolerance?

I'm thinking the rubber throttle body manifolds may be the culprit?

Does anyone have any other ideas? Appreciate any comments.

Re: Cold Start

How are the throttle body plate bushings, do the shafts rattle? Have you looked at the bike via a GS-911 tool to read the computer? Have you used some Techron concentrate plus to clean your injectors. Do you use decent quality fuel? How is your throttle body sync?

I just got my '97 R850R and I noticed when I leave it on the side stand it smokes at start up. I found online that it's common. Up on the center stand and it's fine. I had issues cold starting as well unless I choked the hell out of it. Now I just add a little throttle just after it fires to keep the RPM's up until it warms just a little.
