what's the gap on those plugs?
maybe carburetor rejetting/rebuild?
I have an S&S on my '78 and it would stall after few interstate miles... I cannot remember if it was the main jet being too small or the float bown set too low

I have tried .20 & .25 gap. I can not tell a difference between them. As far as the carb goes I just had the carb rebuilt and new jets put in so I have ruled that out but maybe I shouldn't just yet.

Im going through all the step to getting this bike running good and still haven't found the problem yet. So people were saying Vac. leak so I try the propane and nothing happened. When I was at the HD dealer I ask about new seals. So for $6.00 I thought why not. Boy am I sure glad I did. The rings where a hard plastic but I don't know how there sealed up. I cleaned all the rtv off and used the new rubber band style seal. I will need bigger clamps but made do with these cheaper clamps.

Like the others have mentioned get rid of that fuel filter if the glass breaks and also they have been known to loosen up it could be all over

I have moved on to the next step to get this thing running good. So just a recap I've had the carb rebuild and re-jetted, new blue streak points and condenser, new advance unit, resealed intake, new oil lines, new gas line, 3 sets of plugs and a new solenoid. I was getting spark but maybe there was something I was missing. I dropped the coil and broke a small piece off. It didn't affect the way it worked but I wanted to replace it anyway. After see that there were different coils for points vs electronic ignition I talked myself into a new ignition system. I know nothing about them but keep reading good stuff about dynatek. I ended up getting the Dynatek 2000i. I got it installed today but didn't realize I needed an ignition rotor cup and of coarse the HD dealer doesn't have one in stock. I sure hope this fixes it and all is good.

Part of setting the timing I had to look at the flywheel for tdc. I was told it had a stroker kit when I bought it but had no way to prove it. But there was a number on the flywheel R931-3S. Anybody know what that means? There were also a few more marks.

I just called S&S and was told the first part is serial number. Then 3 is for 4 3/4 stroke, SE is for 1955-early 1981 and X is for 8 1/4 diameter flywheel.

Well I got everything setup today and by the grace of god it seems to have fixed the issues I was having. I just need to figure out what setting to use. To start out I choose to use Curve 2 and dual fire.

I got all of this stuff done and took it for a ride about 30 miles Friday night and all was well. I went out Saturday for a ride and about 10 miles from the house it started acting up. This time I went ahead and keep riding with the group for a total of about 50 miles. I was able to narrow it down little more. I seems to cut out when Im in the higher RPM's. It also seems to happen when I'm staying at the constant speed. If I grab the gas it takes off like normal. If I shift up to the next gear it stops instill the RPM's get higher. I don't have a tachometer to know exactly where it starts at. I didn't notice it be to picky about the speed. Today I drained all the fuel out and removed the petcock. Everything seemed to look good but I blow it out with the air compressor anyway. Still does it. Anyone have any more ideas what to check?
