hot weather starting

It's 95 deg. here in so. wisc. today. And my 07 dl1000 coughed and gagged trying to start this afternoon after leaving work. I've noticed that when the bike sits out in the heat for ext. periods of time. Cracking the thottle once will help it start. But today I had to hold the throttle open for it to start and to keep it running. Then the smell of raw fuel. I'm using 87 octane. Any ideas?

Manual calls for 91+ octane... might be worth testing.

The raw fuel smell after cracking throttle during starting attempt is probably because it's fuel injected... thought you weren't supposed to offer any throttle to fuel injected engines on firing? I'm not a mechanic...

Manual does not call for "91+"...............might try opening the fuel door "before starting" when sitting in the sun/heat for extended periods, and cracking throttle before starting won't hurt anything.

FI engines have a starting circuit designed to start with the throttle closed. However, if heat causes excess fuel evaporation, the over rich result can easily be overcome by opening the throttle until it fires. I've had to do that twice in the past couple of years until the trip to the Rapid City rally. I couldn't keep count of the times on that trip without taking off my boots.

Pat- 2007 DL650A was ridden to all 48 contiguous states. I didn't quite make it to 17,000 miles on the 2012 DL650A.
Nicknames I use to lessen typing, Vee = 2002-2012 DL1000s. Vee2=2014-2016 DL1000s. Wee = 2004-2011 DL650s. Glee = 2012-2016 DL650s

I guess only my Suzuki factory service manual for my '06 DL650 calls for 91+ octane? Shall I photograph the page to support my claim?

Best of luck to the OP on your issues. Thank you Greywolf for the information about FI and hot starts. This is my first FI motorcycle.

91 by the RON(research) method used in many countries is the equivalent of 87 by the (R+M)/2 method used in North America.

The quote from the service manual is:
Use only unleaded gasoline of at least 87 pump octane (R+M)2 or 91 octane or higher rated by the research method.

There are a number of specification differences between the 650 and the 1000.

If you get to it...
and you can't do it...
then there you jolly-well are,
aren't you?

More eloquent, too. The octane information is also new to me - and I'm still running (10% ethanol) premium in mine!

Later tater,

thanks for the replies, I'm trying 91 octane from better stations. And the last 2 days here in wis. it didnt make it to 70 deg. So we will wait and see. Another thought are the spark plugs, they are close to there first recommended change (10,000 m.) Is 10,000 agood time to change them or are there definate signs to change them. My klr650 would start losing mileage when the plug was (wearing out) new plug and the mileage was back.
