My FXE will not start. I have great spark at the plugs. The S/S carb, squirts plenty of fuel when you twist the grip. I pulled the points cam, to make sure it is in there correctly, which it is. The compression is a problem. I have 180# in the rear cylinder, but only 130# in the front. Obviously a problem there, but I would think I would still get some pops or even get it started. It will not fire at all. I would appreciate some help from someone out there. Thanks, Mark

 

A little more info would help... how long have you had the bike? Still original bore and stroke (1200).? What mods? Have you done anything to the motor recently? ANY changes at all or did it just stop running?
Sometimes with the compression being that far off would it indicate the cam off a tooth. but you didn't list any other info...

I looked into your other posts and it looks like when you recently purchased this bike it was always like this... So first thing I would do is check the cam timing.... According to your other post it appears you have a FSM so it shouldn't be too difficult for you...

 

Have you checked the intake manifold seals?
There is plenty of compression for it to run.

 

Spray some fresh gas in it carefully. If it's getting spark and fuel, it has to be bad gas or the spark time is way off. That is pleanty compression to start. Probably not idle very well. Probably valve seat problem on that one cylinder hopefully. Leak down tester will tell you where problem is.
Does it have points? Then it's a simple check to see if it is firing near top dead center. Scrap of thin cigarettes paper will pull out at top of compression stroke.

 

Yes, the bike ran somewhat ragged at first, but always started. The bike has had a different cam installed, as per the previous owner. I will check the cam timing. Stay tuned. And thanks for the input. Mark
