Engine Runs Rough For 15 - 30 Seconds

[Guest rock-rocker]

I'm trying to find out if anyone else has had the same problem as I am having and if so what they found out. I have an 06 Midnight Venture and have the following weird thing happening. Lately I have been driving my bike to work in the mornings. After the bike has sat for the day when I go out to go home it will fire up with no problem but when I go to drive away it starts out fine but then after a few hundred yards it loses power and feels as if just bogs down. This happens if the choke is on (I tried all positions) or off and only on days that the temperature is above 90 degrees. This has been happening since I bought the bike and I guess now that the riding season is on again I want to get it taken care. It's hard for me to take it to the dealer since they are around 40 miles away and I have no way to get back home. I changed the plugs a few hundred miles ago, synch'd the carbs with a CarbTune, checked the vacuum lines and fuel filter. The bike only has 5K miles on it. If anyone has any ideas I would highly appreciate it. Thanks...

Sounds like Fuel Issue to me, maybe the Fuel Pump isn't working or not working right.

 

 

Reason for my Guess is, when the Days are hot, more fuel evaporates from the Carb Bowls and the Bowls are emptier than on cold Temperatures. The Pump should fill the Bowls, but if it isn't working or isn't working right, the Bowls will be filled only by Gravity on your Bike, but this takes longer than with the Pump working. If you switch the Key, you should hear a 'tack tack tack' Noise coming from somewhere. If my Theory is right, you should have similiar Problems when riding with full Throttle on a longer Distance. I'd check the Fuse first, then if the Fuel Pump gets 12 Volts on the Connector.
