trouble with 01 Nomad

[01nomad01]

I have 2001 Vulcan Nomad 1500 45,000 or so. I’m have some trouble, when I start up the bike and ez on putting it in 1st gear and ride on smooth roads, bike warms up and no trouble, but if I start the bike and put in 1st a little hard it starts to idle rough and if I try to go it dies. I have to throttle it high. Then it will go but keeps trying to die on me until it warms up. (1-2 miles). Here is the kicker if I ez it into 1st gear and go down a smooth road its ok, but if the road is rough (bumping) it starts to idle rough/backfires and if I try to throttle it dies. I have to throttle it high. Then it will go but keeps trying to die on me until it warms up. (1-2 miles). After it warms up I have no trouble. I go in some where and get back on the bike rides fine. Started about 3-4 weeks ago.

Welcome from Florida. Try running some seafoam through it and clean out the throttle body carefully.

Is the bike carbed or FI? If its FI try scrubbing the throttle bodt with carb cleaner and a toothbrush. If its carbed you may have to remove the carb and clean it it. It sounds like you may have some crud in the fuel system. Perhaps flushing out the fuel tank may help if it has crud in it.

Its FI

Clean the throttle body bores and both butterflies really well with carb or throttle body cleaner. Scrub them with an old toothbrush or something.

Try 1 oz Sea foam per gallon of gas and run it until the tank is empty and more than likely your issue will be fixed.

check for any rubbed thru wires between the frame and the top of the rear valve cover (rear area of the cover) have something simular and kept getting worse until fi light came on, insulated the area as a temp repair until winter when i can pull the fuel tank.....used some cooking paper with black electrical tape on it, wiggled it between the wire harnesses and the valve cover to insulate it..

mine has a "miss" intermittent cold, got worse, bumps effected it to point i thought i had bad fuel or throttle position sensor was going out....found the rub thru by taking seat off and wiggling wires until would want to stall when i moved the harness

I had the same problem with my 01 nomad...i had it remapped and it seemed to help....the computer that is .

I had a rub issue with the Throttle Position Sensor wire. When it grounded out the frame, it acted exactly like what you're describing. I'd trace that wire from the sensor all the way back to the ECU.
