2007 yamaha v star 1100 classic. Will run for about 5

Customer Question

2007 yamaha v star 1100 classic. Will run for about 5 minutes then shuts down. I have to wait until it cools and it will run again for another 5 minutes. before this happened i noticed i had low engine oil. i filled it and it didn't stop the problem. Any ideas? is there some type of thermometer that shuts the engine down? maybe that needs replaced?

Customer: i bought the bike used this summer. they did an inspection before they sold it to me and i believe did an oil change but i never verified

Hi and welcome to the site, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.

Initially, let's check/review the basics. Proposed preliminary tests (if have not been done) after the "...5 minutes then shuts down...":

  • attempt to start again (even if it will not catch/run);
  • work the throttle as if flooding the engine;
  • carefully remove the spark plugs;
  • note if the tips are wet with fuel;
  • cautiously perform a spark test.

The above would determine if the issue is electrical/ignition or fuel delivery/starvation.
