Gender:	Air-cooled engine question? 08/28/17 at 11:44:11 Does it make any difference engine-wise doing a daylong ride in 80-90 degree weather versus the same ride in 60-70 or 70-80 weather. Reason I ask is because on 2 days last week I sensed a wave of heat rising up that i hadn't felt before, mainly in slow moving traffic. Cooler weather is at least 2 weeks off.

It sure can...the two times my head temperature got to 300 degrees were on 95 degree days - once in downtown Pidgeon Forge on Main Street, the other one was a 1st gear climb up a steep gravel road (little air flow to the engine in those situations).

Air cooled bikes don't have a thermostat - so the operating temperature is directly related to the air flow....and the ambient temperature. They run cooler in cool weather - hotter in hot weather.

And Gary is probably correct as most air cooled bikes were designed to work in extreme climates - however I wouldn't recommend riding the bike at sustained high speed on the interstate during a heat wave! Cool

Reply #3 - 08/28/17 at 12:42:28 An old air cooled VW mechanic friend of mine once told me that you should run an air cooled engine as rich as possible without sooty plugs. The leaner the mix, the higher combustion temps.

VW's had a fan ,Harleys run both cylinders on one piston rod which means the cylinders are directly in line and the rear cylinder usually runs hotter, unlike the Yamaha Virago's which ran two ,and had the cylinders offset to have better cooling.Dino oil is good to 350 degrees , syn. to 500 either should do the job even on the hottest day.

Reply #10 - 08/29/17 at 18:54:24 wrong Kris! thicker oil has already been test by Vercy and shown to make the motor run hotter .It doesn't flow as readily through the motor thus it tends to carry away less heat . oil in an air cooled engine has two jobs, to lubricate and act as a coolent.

Correct me if I'm wrong (it's been known to happen before) but didn't Versy test a few different weights and found that beyond a certain weight the temp got hotter? In other words, we're safe up to a certain weight?

I might be dreaming this up.
