Problems...

[SuperiorKolours]

Ok so I changed the spark plugs the other day at the auto parts store as they were closing and using there tools. I gave them back, they were tapping there foots to hurry up, so they could go home lol. Anyway, they leave and I start the bike up and it sounds like its only running on one cylinder, so I decide to just hobble it home and look at it there. Why do I always do that...smh, anyway half way there the bike stalls out and I pull over, cant get it started again. I look down and its spraying a little gas out of the left spark plug hole on the rear cylinder. So I figure it wasnt firing because of a lack of compression and flooded the motor and thats why it wont start.

I get it home and let it sit over night tighten the spark plug up and it fires right up. Im happy, I take it for a test ride and its running strong until 2 miles down the road it stalls out again.

I get it back home and let it sit overnight again. This morning after I charge the battery because I killed it trying to start it the day before and it fires right up and then runs for like 10 seconds and dies. I check the oil and it is overfull and smells like gas.

I drain the oil and put new oil in. I start it again and the only way it will stay running is if i hold the throttle open. Smoke is also blowing out of the rear cylinders exhaust. I let it sit for five minutes and start it again and it does the same.

Im thinking maybe I blew the rings from running it with the oil level to high and that gas in the oil.

What do you think?

Well, it depends on how over full the oil was as to whether or not you did any serious damage, it would have to be extremely over full. Either way it didn't "blow the rings". What ever that means, it's not a result of too much juice in the bottom end.

Your bike is running like sh!t because of the carburetor problem that let to much fuel get in to the engine in the first place. You have an inlet valve/float problem. The carb needs to come apart.

What he said...carb...float = gas in oil

Ok so why am I smoking out of the exhaust?

It depends on what color the smoke is.
Black smoke is excess fuel. Blue smoke is oil. White smoke is moisture, smell it. If it smells/tastes sweet, it's coolant. If there is no smell/taste to white smoke it's probably just condensate.

It was blue at first then white, I didnt notice the smell. I will smell it tomorrow. Taste? lol

Gas in oil destroys its lubricity. Result is smoked bearings if its ran for too long.

mm, idk. I only got about 200 yards before it died, and before that it was running strong and I wasnt going very fast.

You probably didn't do much damage then. I'm with the rest of the crowd, carb problems. Maybe dirt in the tank is obstructing the needle valve from closing all the way or maybe your float is roached. The smoke is likely from unburnt gas built up in your pipes, should clear up. If you are mechanically inclined fixing carbs is no biggie. I just bought my shadow and have never pulled the carbs off of one so Idk how much of a ******* that is to do but on a dual-carb v-twin its usually no fun at all. If you feel up to the task get yourself a big can of carb and choke cleaner or you can boil the carb in 50-50 water and pine sol. Either way just keep the pieces organized and take one apart at a time so you have an assembled unit to refer to if you get lost.

Just tried to start it again. Wouldnt start unless I held the throttle all the way open and took several tries. Blue smoke is gone. Now white smoke, reved it hard several times and the white smoke cleared but shot out a little black smoke when the rpms shot up and then it dies when I let off the throttle and white smoke seeps out of the exhaust. I cant tell if its sweet, dont really smell to much.

I know you guy are saying the carbs need cleaned and they do, but this bike has been running decently for 3 weeks, I dont get how all of a sudden now it cant even stay running.
