OK Well the bike is painted and back together and 99% complete. Got a few wires to reconnect and a few things to zip tie and hide and shit like that but I can't get this thing to run right to save my life. After I finished the mock up in November I had been riding the bike around unpainted for about 2 weeks to make sure everything was in a good spot and nothing was rubbing or needed to be adjusted or moved before I took it back apart for paint and chrome. I was riding to work one morening and went to get on the interstate and hit it hard on the onramp to get up to speed and it just wouldn't go above about 55 mph. I thought I'd gotten some shit in the main jet because it was only above half throttle so I turned around and limped it home. I decided I'd just take it back apart and clean the carb while I was at it and I did. I got it back together Tuesday night and fired it up and its still doing the same shit. Idles and starts fine but when you get above half throttle it just starts missing super bad and shooting flames out the exhaust. I've been at it for 2 nights trying to fix it and I'm going to try and swap my carb for a buddy's and then swap my ignition with another friend who has the same one and see what happens. Here's what I've done so far:

We had the same problem a few weeks ago on Wesley's Ironhead...main jet was clogged...blasted it clear with the air nozzle. Does it idle high? Could also be your air/fuel mixture...
ReplyDeleteI've cleaned and checked the (entire carb, including the) jets 3 times. I even swapped out the main jet for a 170 when I was running a 180 just to see if it did anything and i tried taking the air filter off to lean it up a little before I changed the jets. I'm headed to get new intake seals and plugs afer work so I can write that stuff off.
