When after say a minute or two of running ( you shouldn't idle a 2 stroke for more than a couple of minutes at most ), ride it nice and easy for a couple of miles to ensure all the pistons and internals are thoroughly heat soaked. Riding it easy like this keeps the engine under load creating heat and ensuring that all the internal components are heated up, or "heat soaked".
This is a good and easy way to warm anything up and especially important if you are running forged pistons that have a greater piston to wall clearence or "looser" fit. But this is a safe way to ensure all engines are properly warmed up.[/b]
Sorry but no heat exchanger on a fan cooled machine.[/b]
until you can feel some warmth in the heat exchanger.[/b]
that's what he does and so do i. i used to make sure my son's old hairblower was pushing some heat out of the fan though before he took off. when i wasn't there??? who knows?Sorry but no heat exchanger on a fan cooled machine.[/b]
