Hello, I'm Gavin and i have a 2003 Ltz400.

I have a 2003 Ltz400 and its been giving me some issues. I can crank it up no problem but once i ride it for a few minutes and cut it off it wont crank back. I have to let it set for awhile and let it cool down before it will crank back. Any ideas of what this could be?

Welcome! Checking your valve clearance and cleaning the carb could both fix this.

Hey Gavin!

I had a similar issue on an old go kart of mine. Valve adjustment was messed up. I fixed that and it ran fine ever since. Good luck!
