Hello,</P>


I've got a 75 XLCH Sportster (1000) (had a long time) with 22K miles on it, drag pipes - all stock . . . stock Bendix #16P12 carburator</P>


To prep it for cold starting, I twist the throttle 3 times (don't use the choke) and give it a good kick, it normally starts on the 1st kick.</P>


Then I increase the idle to around 1200 RPM until it warms up, then back the idle down to 900.</P>


Took a ride on Sat, and after the engine warmed up (20 minutes) as I was going around 50 MPH, the engine started coughing, some kinda of fuel problem.</P>


When I got home, I pulled the plugs and noticed that they appeared to be either oil or carbon fouled (according to the Cylmer book)- using Accel plugs with 3K on them.</P>


So, I cleaned them up, (used some sand paper between the gap)blew em out good, checked the gap, looked OK, then regapped at .028 (Clymer book says .025 - .030) and put them back in. Have yet to ride the bike since then.</P>


But wanted to fix the fouling problem before I took another ride.</P>


Any and all thoughts, comments greatly appreciated.</P>

Dont know if this helps but;
Your problem could be your valve stem seals. If you have left the bike sitting around (for a few years) the seals dry out and may attach themselves to the valve stem. When the engin turns over the seal is torn (or as in my case they total discentageted). This lets oil flow down the valve stem and into the engin.

[sm=icon_blah.gif]I agree with Peter.valve area may be suspect.wish they still made leaded gas for us.Feul filter probs plague me once in a while too.
