How long can i run my air cooled 250R trik before having to give it a rest because of over heating?


800

 

If it's stock, you should be able to run it as long as you want. Just make sure you don't run it lean. It will cause it to run hot. I have run my 84 atc 250r that was bored .80 over, ported, polished, head milled, piped, reed cage, 39mm kehihn carb, and clamp on k&n for hours wide open in the dunes and didn't have an engine failure. I can tell when it is hot the idle will pick up and it doesn't have as much power as when I first start it. If it feels hot or sounds hot, let it cool down. I've got an 83 with a 300 big bore kit that is at it's last bore at .100 over that's heavily modded as well and have run on the same piston and rings for about 2 years now. Every time I get on it, it's wide open throttle every gear. Use a good oil like klotz or maxima and mix it at 32:1. Just use your head and don't overrev and get a good oil mixture and you should be allright.

 

YOU ARE RIGHT.

 

now by lean you mean too much gas and not enough oil mixed with it right?

thnx
