After this, the big ran fine (stock intake) except for popping from the exhaust on decceleration (some guys like this...) which went away after chaning the air intake to a Ness Big Sucker and re-jetting. It runs great and is loud enough for me.
I did the same to my 03 Wide Glide earlier this week around 1500 miles. It sounds much better, and I'm even getting better gas mileage. I was getting around 36-37 MPG now I'm getting 41-42. The engine seems to breath easier and it runs great...I'm not getting as much burping as I did before, especially below 40 degrees. I looked at the plugs last night after putting about 400 miles on the bike and they look fine. I'm not planning on doing anything to the carb unless I need to down the road.
The dealer won't do it. It'd probably void the warranty. It's real easy to do...I did it in less than an hour.
Remove the slip on's, set them up right on a block of wood, get a piece of pipe or a dumb bell bar and a hammer and knock them out. Re-install the slip-on mufflers and there you go. Just keep an eye on your plugs to see if you need to re-jet later on.
I just got my 03' wide glide yesterday it was very cold riding it the 10 miles that I rode it.. I think the sound of the stock exaust very much resembles a Vespa moped.. I've decited to live with it till spring (seeing how it is winter) when I can get Big Shots for it.. I didn't even get anyone to look at me . I'm embarrassed......
Has anyone out there done the punch out thing with a 03 fat Boy stock exhaust with EFI? Until I scrounge up the funds to buy louder pipes, I would like to try this trick to make the bike sound a little more beefy. Right now it sounds like a lawn mower.
