had this problem on my X1 for a while.. i believe it was because the intake air temp sensor was warming up after shutdown, then giving the ecm a skewed signal during the warm starts. after ceramic coating the header i haven't had any further problems. I know the IAT is in a completely different location on an XB, so heat may have nothing to do with it.

If you wanna test the theory though, pull of the airbox real quick after getting the bike warm, then pull the wire off of the sensor and see if it starts up better. unplugging the sensor will throw a check engine light temporarily. It will start and run alright, but I don't suggest riding with the sensor unplugged for any length of time.

The IAT is inside the airbox near the filter and crank breathers. The XB's are harder to start without that sensor plugged in.

I'd go with basics.

It's a dying battery. You get one good start a day out of it in the cooler weather. The longer it has in between, the easier it lights up.

Longer rides, battery tender, should help.

Same as the winter car thing.

+1 on the battery. Have it load-tested at an auto parts store if you don't have a good quality battery tester.

i have the same issue on my xb9...i dont think its the battery...it seems to crank the starter ok. just takes a little longer to start when she's warm than when she's cold.

she will still start though.

Roger that Chessm. i have the same problem on my XB9S during the summer. ive always assumed it to be the race ecm being to hot but never looked into it too much. usually if i stop, even if its for gas, i'll let the bike cool down a couple minutes and stretch my legs.

Yeah, after it sits for 5 minutes or more, it's all good. Yesterday I rode and it started up no problem after just a 5 minute ride and a 2 minute sit. It was 40 degrees though, so I just assumed it had sufficient time to cool down. The fan runs for a few minutes, but we all know that's just what it does........

Anyways, I guess I won't have to worry about it for a few months.

I cut my bike all the time at red lights, never had an issue restarting, regardless of temperature.

Froggy,

Now I am getting some insight to the high gas mileage you often report. Lets see;
-Cutting off the engine at lights (just admitted too)
- Coasting down hill with motor off (conjecture)
- Drafting behind semi's (conjecture)
- Driving 50 on the expressway (conjecture)
- Giant magnet hidden in the fairing (guess)

What other devious methods do you employ to make our mileage look so bad?

Tuck in, clubman bars make it easy

Memorize the timing of lights, predict when they will change

Predict traffic patterns, don't bother tail gating around town, your both are gonna get stuck at the same light, but you can coast that last bit. On the highway tailgate as much as you safely can, hand on brake lever at all times

Increase tire pressure a few pounds if you know your not going to be hitting the twisties

Run a lighter weight oil

Carefully plot your course on google maps to minimize traffic interference, stop signs, etc.

Fill your tank during the coldest part of the day

Participate in hypermiling races ( http://ecomodder.com/forum/showthread.php/m-e-c-fa ll-economy-run-iv-november-10203.html )

There is a bunch of other things too, but you nailed the biggest ones : )

Oh, and I got 75mpg once without doing anything posted on this page : D

Well Froggy I can say one thing about the clubmans on the CR you may be right I rode the CR today with your high bar and its comfortable way more comfy but there is something missing I kinda liked that aggresive feel carving the corners but I am to fat and to old to keep the clubmans but don't let kill ya on that one the clubmans have the performance edge hands down and you are not in the wind. sorry to thread jack

No, you can't have them back : D

Oh, and my right wrist, which is still recovering from the wreck, hates it, but I HTFU and rode to Boston last night and back home this morning. : )
