Hard start due to foggy nights?

Has any of you experience this. Ill get off from work around 7ish, then try to start the rod, and it's having a hard time starting, then when I finally get it to start if I don't hold on to the throttle it will stall sometimes I even have to hold it down all the way to 4k rpm just to keep it alive. Then when I'm finally off I have to basically make the rod scream just to keep it from stalling.. After 20 minutes of riding then it will go back being normal again. I only have this happen twice and most of the time the bike gets wet/moist due to fog, any thoughts guys?

dont twist the throttle at all when turning on ign and starting.if its not that, you may have to clean out the iac port and check iac motor for correct operation.spark plugs may be overdue.

Something is wrong, either with the tune or EFM. The fact it rights itself when warmed up tells me it's an air/fuel problem, not enough gas/too much air when cold. There's no physical choke, it's in the fueler's programming. Check sensors and their connections (air box) and exhaust sensors and connections.

thanks for the reply guys, and heres what bothers me. yesterday i went home from work, i took it off the garage decided to try and go to the gas station and this time the rod is dry coz it was sitting on the garage, and guess what nothing seems to be wrong started just fine, revs like a champ, and its like it never had a problem, i seem to only get the problem when it stays too long @ night and collects moist and gets wet. still undecided if i should bring it to the stealership.
@pecee sorry for being a noob, whats the iac port and iac motor that your talking about. where is it located and what exactly its purpose?

@Vambo thanks for clarifying about the choke, i was wondering about that. you said "Check sensors and their connections (air box) and exhaust sensors and connections." how do this sensors & connection looks like, and how would i know if theres something wrong with them?

Based on your reply you really should just go to a reputable mechanic or the dealership. If you love your bike, look after it and get it looked at bro.

I agree. Have a pro take a look at it.

Just make sure all the connections are in place and tight. Might save a trip to the mechanic.

the system relay could be worth looking at,replacing.its cheep.the early models with the fuse pack behind the airbox were worse than the late models but i found moisture was a cause for failure of these.

I agree with Vambo, this does sound like a air/fuel prob. There is no choke and EFI can be adjusted by adding a Power CommanderV EX from Dynojet for Harleys:

Question is did you change or modify you exhaust system? I put a Power Commander on when I added my SuperTrapps.

Or better yet, remapping the existing fuel control.

I never like the stock stuff or OEM, that's why I'm a modder!

The stock EFM is an excellent unit. Unless going to an auto-tune I see no benefit to after- market "peripheral" tuners. HD has some useful functions programmed in that gets by-passed.
