HI,

Can you tell me the normal temperature range for the Yamaha YFM 350R ATV motor? I'm a electronic engineer and im doing a electronic air cooling system for that motor.

Engine type: 1 cyl. 4-stroke, SOHC (air cooled)
Displacement: 348 cc
Bore and stroke: 83 x 64.5 mm
Compression ratio: 9.2 : 1

Thank You,

Answer
Hi Pedro,

I respect your engineering discipline. Your project sounds interesting. However, I don't have the specs you're asking for.

I do have a Pyrometer and other tools for measuring temperature.

I doubt the information could be found in the Service Manual. Try contacting Yamaha directly.

Respectfully,
