#24594 Musky (User) Platinum Boarder Posts: 15137 Re:Engine Cough 5 Years, 1 Month ago   Hey jso Don't have a clue what your talking about for the most part but I agree that once you start doing mods to the bike you can't go by stock settings anymore. The bike's gonna want what it wants.   Logged       The administrator has disabled public write access. #24599 Ole (User) ^ Redneck ^ Gold Boarder Posts: 967 Re:Engine Cough 5 Years, 1 Month ago   You nailed my point Musky. Gee, you have a knack for doing that, dontcha know. Once you move away from stock parts you can only really use some specs as a baseline and then it's tinkerville to get things dialed in. That's ok with me though as I have almost as much fun wrenching as I do riding.   Logged     2005 Silverado Chopped KZ   The administrator has disabled public write access. #24804 Razor (User) Senior Boarder Posts: 219 Re:Engine Cough 5 Years, 1 Month ago   Well guys I just now today am able to find time to mess with the carb a little. I decided that my first step would be change the air filter since I could blip all I wanted last summer and it made a definate improvement. I took it down the road and noticed that the cough is gone if I pull the choke out or even partially out. I decided that I would mention this as it might be a clue as what to do next. As I said, I could blip all I wanted last summer with no cough. It isn't that I like to really blip, just crackle the pipes a little sometimes.   Logged       The administrator has disabled public write access. #24806 DocShadow (Admin) Hmmmm .... send beer Admin Posts: 17615 Re:Engine Cough 5 Years, 1 Month ago   A carb cough usually signifies a lean condition. You have more or less verified it by pulling the choke out a bit and seeing the cough disappear. Try turning your PMS out 1/4 turn.

This past weekend, I installed a tach and found that my idle was set at about 750 RPMs. I bumped up the idle to spec (850-950 RPMs) and the cough went away!

Also thanks for the idle info as mine was a little too high. Besides fixing the cough, I noticed a definate improvement in fuel economy. I haven't checked it yet to see my actual mileage is but there is a noticable improvement.   Logged       The administrator has disabled public write access. #25405 Ole (User) ^ Redneck ^ Gold Boarder Posts: 967 Re:Engine Cough 5 Years ago   Mine's not coughing anymore either after bumping the idle up. I also adjusted the cables to have the proper 4-8mm free play at the grip. Went for a 200 mile run into Wisconsin last Saturday and she ran flawlessly. Not a single cough.   Logged     2005 Silverado Chopped KZ   The administrator has disabled public write access. #25411 06MidnightStar (User) Gold Boarder Posts: 768 Re:Engine Cough 5 Years ago   Yep. The idle tweak fixed me up, too. Funny, I readjusted my throttle cables, too, this past weekend, since I already had the tank off to install the tach. I had noticed that there was no free play in the cables. The dealer adjusted the cables at the carburetor, so there was virtually no wiggle room at the throttle grip. Arrggghhhh! I repositioned the pull cable so that all of the adjustment was at the throttle grip, then made the final adjustment at the throttle grip. We're good to go now.   Logged     ---- 2006 Midnight Silverado, MaxFlo Air Kit, Roadhouse Classics 2-1 Pipes: OEM manifold, 190 Main, 37.5 Pilot, Needle (3rd groove, OEM white spacer), Maxmix Pro PMS (2.5 turns out), Accel Pump Duration (1 turn out, nut in front), Float Height (w/carb upside down): 16mm, 43+ MPG   The administrator has disabled public write access. #25417 Big Bear (Moderator) Who loves you , Baby? Moderator Posts: 6997 Re:Engine Cough 5 Years ago   I think some of us (me , for sure) love the sound of a slow loping v-twin. Problem is, the motor is not fond of those running conditions. Besides, who wants to idle anyway, when you could be out RIDING! BB   Logged       The administrator has disabled public write access.
