When you open the throttle during cranking, you're giving it more air. This tends to point toward too much fuel before the engine starts.




Can you answer any questions from my first post?
Yes sorry,

-the floats shouldn’t be stuck because I had replaced the float valves and when re-installed they worked perfectly.
-both cylinders are getting hot if ran long enough to heat up.
-the only smell I believe is burning oil/seafoam.

Hi drop your oil get both piston to the bottom of there bores and fill the bores with diesel it will work its way past the ring and drain out the sump keep topping the bores up with diesel for a couple of days this should free up any gummed rings I have used this method on my cx650 custom that was burning oil and it worked great saves rebuilding a engine just to free the rings its a cheap fix if it works

I would definitely try this before tearing into it. Diesel, kerosene, Marvel Mystery, $eafoam .. first two are cheaper.

Oil rings are two very thin rings with a corrugated metal spacer between them, it doesn't take much to let them stick.

Pb blaster, wd40 also work to free up stuck rings. But at 165 psi per cylinder I don't think your rings are sticky

I agree, at 165, you have plenty of compression. BTW, you only need to check it in two places. There are only 2 cylinders, so you will get the same reading no matter which side you check them on. Now I would suspect valve guide seals. What weight oil are you using? I recommend 20w50. The thinner the oil, the easier it is for it to leak past seals. If you can afford it, you could even try 60w racing oil. I wouldn't leave it in there too long, just see if it smokes less with it. If you can drain it out without contaminating it, you can put it back in the jug, and mix some with regular oil at every oil change.

I have a 1964 Ford with leaking valve guide seals. It has plenty of compression, but it still smokes, especially on startup, and burns oil. I decided not to do anything with it, because the oil leaking past the valves actually helps lubricate them, and help prevent damage from ethanol gas.

I would just go ahead and ride it a while, and see if the smoking stops. About the worst it can do is foul plugs.

I am a motorcyclist, NOT a biker.

The top rings are for compression the oil control ring is the one that gets gummed up even if you have good compression the oil control ring if gummed up it will burn oil ie blue smoke when running

Okay so all is good, bike is running and I was able to ride it for a little before the battery died on me. (New one on its way.)

-I sprayed a little Seafoam into the spark plug holes and let it sit for a couple of days.
-I took the carbs off a second time and flushed them again.
-I played with the fuel and air ratio.
-After riding the bike, I tried to jump it so I could ride it home and I’m not sure if I fried something. ALL LIGHTS ARE WORKING EXCEPT FOR THE HEADLIGHT AND THE STARTER ISN'T TURNING. ( I keep seeing this 2 wire bypass, but I’m not sure if that’s going to fix the issue.)

Don't jump off a bike from a vehicle that's running or you will likely fry something.

The jump was unsuccessful. I tried to jump it without having the car started.

Check your fuses, and double-check that none of your lockout switches are stuck (clutch, neutral, kickstand).
