Starting my 62 FLH

#1

Post by tattoomark » Sat Sep 09, 2017 5:42 pm

I have a question about my 62 and wondering if somebody could give me an idea what might be going on when the bike is cold starting the bike is easy if I let the bike get hot or warm in the garage shut the bike off go to started again the bike fires right over easy But after I ride the bike the idles fine there's no air in take leaks I shut the bike off go to start her again while hot/warm I can barely kickstart it and I can't start the bike until cool I can stand on the kicker pedal/arm and I'm 200 pounds can barely roll the motor over only after I have ridden her any ideas? When the bikes ridden she runs great no issues shifting or at a idle.

One thing that comes to mind is that your float valve is hanging up or the float is set too high in the float bowl, causing fuel to run into the cylinders. That would make it very difficult to turn the engine over. A test for this would be to shut off the fuel petcock (assuming it works), and see if that makes a difference in a warm restart.

Thanks for your input but I'm thinking this is not a fuel issue the kicker arm doesn't want to go down easy extremely hard
What i just did might be a fluke i pulled the clutch lever in kicked the bike over 3 times released the clutch and bike fired right over now I'm starting to wonder if it's clutch related or transmission related I'm going to take it out for a ride again shut it off and see what happens

If there is excessive fuel cleaning the oil off the cylinders,. You should be able to smell gas in the oil tank.

But wouldn't the spark plugs be fouled? Just asking
The biggest thing I notice is when the bike is cold the kicker arm goes fown easy when hot it harder and not as smooth

Thats odd because your not turning the engine when you have the clutch lever in,at least it shouldn't be turning...

Yeah, that bothered me, as well. The kicker won't turn over the engine if the clutch is disengaged.

I don't understand what you're saying. When you step down on the kicker, the motion is transferred through the transmission (in neutral) to the clutch. If the clutch is engaged, the motor turns. The motor won't spin if the clutch is disengaged.

Lets if i can explain what I'm trying to say motor is hot i try to kick over the bike i am not touching the clutch at all it is hard to roll the motor over
When i said i pulled the clutch in i was only seeing if it had something to do with it not wanting to roll over thats all

Can you please describe your normal start-up routine? You know- spark retard, choke, prime kicks- hot and cold?

I don't see anyone addressing your problem .....try removing plugs and see if it kicks easier ...do you have solid lifters ? maybe they are adjusted too tight .....hydraulic lifters are much more tolerant of heat ..hard to diagnose.... I am interested to find out what your problem is !

You don't say what may be in your engine,Hi Comp pistons maybe or a cam ? Where is your ignition at, maybe too far advanced. Anything else would let you know by sound or feel.When you get it running listen to it and feel it for odd sounds and vibrations.Good luck

Sounds normal, I just had to ask.
What happens if you fully retard spark for hot start, any change? (Likely not?)
Solid lifters adjusted too tight will prevent valves from closing and kicker will just whoosh through, no compression.
What the hell is causing it to bind up when it's hot? Is the primary chain adjusted too tight? (I'm leaning to something in the primary drive, from clutch, kicker, t/o brng,..... I've taken my shot, good luck.)

Thanks for your input the bike has hydraulic lifters I'm starting to lean towards a valve hanging up possibly piston swelling up? Like i said only when its been ridden
This motor virtually has no miles on it it was built by one of the best I'm not going to mention his name but he is retired now so asking him isn't going to help me this is a real dilemma
