Hot Water

Recommended Posts

Hey all,

I taught my girlfriend to ride my bike BUT here is the catch

she putts around which is fine by me and also worries me

because I have always heard "if dont have 2 strokes screaming they get hot"

now I can understand that if it was air cooled

but this is a water cooled bike.

so is she hurting anything by putting around

Back in the day our bikes were cooled by airflow over the cooling fins on the jug, and the surface area dissipated heat really well. Modern water cooled machines need the coolant to be sent through the radiators to keep temps under control. Less speed, less airflow, less cooling, possible overtemping after prolonged putting around. Unlike a hot car sitting in traffic, most bikes don't have cooling fans, so keeping moving is the key.

LOL, i think what you heard was actually in reference to 4 strokes.

i can idle my cr250 for prolonged periods of time, never a sign of boiling over, ever. my friend with an 06 crf450 has a hard time riding trails because his bike boils over if he doesnt keep that thing moving and moving fast. he hardly even lets his 450 idle to warm up because it starts pissing coolant. when he pulls over he shuts down and i just keep the 2 stroke idling away.

i wouldnt worry about over heating a 2 stroke unless youre lean, especially putting it around, the thing will usually run so rich its going to naturally cool it down.
