how do you make a motorcycle engine run cooler?

Answer 1

Make sure the timing is set properly.

Make sure your fuel air ratio is good, ( too lean will cause your bike to run hot)

If you are still running hotter than you'd like, put an oil cooler on, mine dropped the temp almost 15 degrees.

Answer 2

For an air cooled engine, an oil cooler is about the only way.

Answer 3

Scooter Trash has 90% of your problem covered. But, there is a simple thing you can do to the engine, and some ways to ride cooler. My last bike has a 1,200 in it. it would idle at about 950 -1,000 RPM. At the longer lights here in Sarasota I found my legs getting warm pretty quickly. Now I have the 1,450. It has enough oomph to idle at 800 without dying. That is a big help in stop and go traffic with heat abatement. Find the lowest speed your bike can idle at, and set it there. You can always keep a little bit of hand on the wick if you need more idle speed.

The riding tips. (By the way, these go pretty well much just for air cooled bikes. Never owned a water cooled one.) Shift at the lowest RPM you can as still have power if you need it. I can shift at pretty early, usually about 2,200 RPM. But that leaves me at 1,800 or so in the next lower gear, not enough to get on the wick if I have to. I only shift like that when traffic is light and I ain't worried about rear-ending some lost schmuck, or getting run over by some boob in a hurry behind me.

Airflow. Try to keep moving, even just a bit. Every little bit of airflow helps remove heat from the engine. For example; you see the light is red up ahead. Shift into "N" and coast to the light. Try to time is so you can actually keep moving. (Be ready to grab a gear just in case! I've had to upshift to third because some dummy behind me was trying to puff on my poop-chute.)

Try to keep the high RPM's for when you actually need them. A bike sounds cool when it's revved almost to the max, then shifted, but it ain't necessary for regular use. High RPM's generate more heat, and it takes the motor longer to cool down if you have to come to a complete stop. In fact, I hardly ever do over 3,000 RPM's except on the hiway. (Fifth gear, TC-88, 70 MPH, 3,000 RPM's on the nose. But on the hiway I got plenty of airflow.)

And one of the easiest things to do is keep you engine clean. Dirt keeps the motor from getting rid of heat. A nice shiny motor not only looks good, but runs cooler. Keep the inside clean too. Change the oil on a regular basis. I use Amsoil 20-50 in mine. It's runs nine bucks a quart, but that's cheaper than engine repairs.

Ride safe. Ciao!

Answer 4

Move from Tempe Arizona to Pierre South Dakota.

Answer 5

Synthetic oil and an oil cooler.

Answer 6

surround the engine with ice.

Answer 7

i've heard really good things about water wetter... but supposedly you need to change your coolant often with that stuff because it gums up or something

Answer 8

Oil change.
