Overheating... What to do?

[Yamada]

I was slow riding in a trail and my bike ( ytm-200) started to sputter and lost it power. It was full of gas. So I can assume the engine was overheating.
What is the better thing to do in this case:
-Stop, let it cool down, restart.
-Find a strait line and rode at WOT.:naughty:
-stop on the side of the trail and rejet.:Bounce
-Go trought a big puddle of water:crazy:
-Continue to ride and say it was my imagination and it will clear by itself.
Seriously, I don t know was is the better thing to do, is my bike need to be rejetted?
Thanks

are you sure you didn't foul the plug?

Pull your plug, clean it and re-gap the plug. If it is overheating, try rejetting it. When you pull the plug look at the color, you'll know what to jet it to. Black is to rich, white is to lean, tan is perfect.

Might have fouled out a plug. Change out spark plug with a known good plug. I'd make sure the fuel line or filter didn't get plugged up. Make sure you are still getting good gas flow. Check air filter, make sure its clean.
It sounds unlikely that jetting would cause a bike would just quit out of the blue one day without any symptoms.
Could you start it again after a while?
To answer your question, if a bike is overheating, the best thing to do would be to just let it sit (with the engine shut off) until it cools down.
If it is air cooled, then you could turn it off and coast down the road in neutral to help draw some of the heat off the engine too.

Kinda doubtful thats its just overheating for no reason. Now maybe if you have been making modifications/ playing with the carb settings you might get it to run hotter.

I don't think its unreasonable to think that some of your electrical components may possibly start to behave oddly after the bike has reached operating temperature if they are going bad.

Could also be vapor lock in the tank. you have the vent hose on the tank?

Anywho, main point being it could be a lot of stuff. What brings you to the assumption that the bike is overheating?

[Yamada]

Yes I could start it again after maybe 5 mins, no problem.
I don t think I fouled a plug, because after that I use this bike with the exact same plug.
What lead me to think that my bike is overheating is that usually I rode it really hard ( real hard, PInned in the fifth gear on the road, wheelie in the field...), for 15-20 minutes without problem. It is just when I do slow trail riding that it is acting up.

I KNOW my 84 YTM-200 overheats all the time. I don't know if its a Yamaha thing or what. But on a hot day mine is always boggy and running like shyt.

In the winter? She runs like a top.

I have noticed that the ignition coil when heated does not fire properly thus causing very low idles/dying.

I have thought about installing a cooling fan just to cool her down...
