954 rich at startup

My 954(stock exhaust/filter) is always running real rich at startup. If I start it cold it runs rough and smells rich.

yesterday I was doing trackday, and even the engine moderate warm at previous session, it always smells rich after starting. When it runs for couple of seconds it's fine.

Is this common?

Re: 954 rich at startup

first id check your air filter and then the condition of your spark plugs, see if they are really dark from carbon build up since they may not be generating enough spark when cold.

Re: 954 rich at startup

Airfilter is as good as new. Haven't check the plugs yet, they are pretty new.

I think there is enough spark, it starts right up with all four.

Re: 954 rich at startup

Gotta ask...do you have a Power Commander? If so, disconnect it and see if that helps.

Re: 954 rich at startup

My stock 954 does this also. It runs fine after it warms up a bit. I think this is normal best I can tell.

Re: 954 rich at startup

Yep, it's just the start-up map. It's a computerized "choke".

One serious thought though, did it go into a gravel trap or dirt? If so, you need to check the airbox, it's probably full of gravel/stones.

Re: 954 rich at startup

thanks, I didn't crash it. Bought it crashed.

And yes I checked the airbox, it had lot of gravel there. Also at the top of the cam cover was lot of gravel, I vacuumed all that stuff out of there, luckily before I removed the plugs

here's how the bike looked when I got it.



here it's now



frame has been measured by professional, it's staight.

Re: 954 rich at startup

Nice! It looks brand new now. What is that on the cannister? does it work keeping passenger's heels off the pipe?
