Starting issues......
Sorry been off a long time, busy with work, kids... well, i have an 83 shadow 500. When i start it at the beginning of the day it starts fine. My problem is if i ride it for a bit then shut it off (say to go into a store) when i try to start it again, it will not start. If i let it sit for a long while, it'll start again. Does this mean i need a starter rebuild kit? Any and all replies welcome?

You need to be more specific about "won't start". Does that mean it will not turn over or it will not fire up. Two different things. |

If it turns over you more than likely don't need a starter kit. It sounds like a fuel problem to me. Next time try opening and closing the gas cap and see if that makes a difference, it could just be vapor locking. If that makes no difference try posting back.

Ramie is right. If it turns over you don't likely need a starter kit unless it is turning to slow to start(i.e. dragging).
There are several possibilities here. As you said something heating up and needs to cool down before it will restart. Could also be cooking the gas in the carbs when you stop. Never had that happen but have heard of it. Try something next time you ride. Shut it off and then try to restart immediately. I had a cage once that would start fine cold but would not restart until it cooled off unless you restarted immediately. Turned out to be the spark plugs believe it or not. New set solved the problem. Also try what Ramie said. Open gas cap and see if it starts. If so the tank vent is the problem. Good luck. |

When starters go bad, they often won't turn at all sometimes but other times they whiz right off just fine. He needs to check the battery connections, the battery and the charging voltage before moving on to step 2. |

Haven't had the chance to mess with it today yet but will. After shutting the bike off, it will start immediately. The problem is when it sits for a few minutes. Spark plugs changed again about a week ago, still the same problem. Will check battery in a while also. Thanks for the replys...

Wont start hot
You may have a hot soak problem. I think that there are a lot of other threads on this site about problems starting those older bikes after a hot soak. You might do a search for them and see what they did to correct it.
I had an 83 Ford Escort that acted the same way. It would start right up at 20 degrees below zero but on a hot day, if I went into a store and came back out 5 minutes later it would crank but not start. The Ford dealer determined that it was a hot soak problem. The boiling point of gasoline can be as low as 100 degrees with winter blend gasoline. It should be higher than that with summer blend gasoline but it may not be much higher. Once you turn the engine off, you lose the cooling effect from the gas evaporating as it is being pulled into the engine. The heat from the engine causes the carburetor to heat up. The fuel in the float bowls begins to boil. The pressurized fuel vapor doesn't have anywhere else to go so it pushes back against the float needle and up the fuel line. With little or no fuel in the float bowls the engine will crank but not start. The boiling prevents any more gas from flowing in until the carb or carbs cool down a bit and then it will start OK. The dealer solved my problem by putting an insulating gasket under the carburetor to keep some of the heat from the intake manifold from being transferred to the carb base. Not sure that there is an equivalent for your motorcycle carb. Ride safe!

Ok I tried to open the gas tank to see if it was a venting problem to no avail. Checked battery, was at 12.5 so that's good. Sounds like the heat soak is more the culprit. Only prob now is how to keep the carbs from getting too hot ?? I guess I'm gonna recruit a friend of mine to fabricate something to cover or shield the float bowls.wish me luck...
