Thank you, I'm doing a few heat cycles on a new S10 before I hit the street with it. likely meaningless seeing the factory and dealer probably run to redline anyhow. Will make me feel good I suppose. Temp got to 213 and no fan so I shut it off. Will test the fan after a couple more heat cycles.:)

Heat cycles? Why? Get on it and ride. If the bike idles too long it will shut itself off. You'll come back to a dead battery because the lights stay on. 221 degrees is the normal fan on point.

Thanks for the tip, I was unaware that it would shut itself off if it idled to long but it makes pretty good sense, any idea how long that would take ?
Funny how things go, one guy won’t let his bike idle for a couple minutes before taking off and the next guy thinks it’s a good thing to let it idle unnecessarily.

Will automatically shut off after 20 minutes idle
Things I never learned in 130k miles of Super Ten ownership... :rolleyes:

Heat cycling the bike serves no purpose. It wasn't meant to just sit there at idle. No air flow to the radiator. Heat cycling brake pads is a different animal for different purpose. But the engine? What perceived gain do you see from this?

And did you trailer it home? If not, it's already seen heat cycles from the factory and the ride home.

Me and many others accepted break in procedure for new engines. It's not allowed to get to 220. 200 210 ok 190 is plenty, then allowed to completely cool before next cycle; 5 or 6 times done! then the ride in.
yep; dealership enclosed trailer to my house 3 hours from dealership. No way I was riding it on the shit salted winter roads in the midwest. A month ago it would have been ridden home from dealer.

I never start a cold engine and just take off some people get away with it though.

"My" opinion is, with modern engines, start it, put your helmet and gloves on, start the music, and take off. For example, my 2013 Jeep, in less than a mile is producing warm air; after less than a minute of idle. The computer takes care of everything. Technology is awesome....most of the time. Of course, y'all have a whole different kind of cold than down here. When I was in New Hampshire, in the winter, my manual trans gear oil turned into syrup.

Yes... that's for a NEW engine. Neither you or anyone else that's bought a vehicle from a dealer in about 20 years has a NEW engine. New means right after it was built or re-built. It's already gone thru a run in procedure at the manufacturer. In part to check for leaks. The gasket technology, cylinder coatings and metallurgy involved now really doesn't require heat cycling. The perceived benefits don't pan out in reality.

Hey, do what makes you happy. You're doing more harm than good idling the bike for extended periods of time. As I said before, it's not designed for that. (at the end of the day, you're not doing much harm anyway)

I've done heat cycling on motorcycle engines. Fresh build on a '40 HD knucklehead with paper gaskets and cast iron cylinders w/o coatings. And a complete re-torquing of fasteners in between cycles too. No stretch to torque head bolts on that bike! Our current production bikes are simply different animals.

As for starting a cold engine and just taking off. Define cold. When I lived in the desert, morning temps of 85F were common in the summer. The oil at 85F wasn't 'cold' imho. Warming up an engine before heading out is about oil viscosity and cylinder head temps for better, more even combustion. With EFI and air flow, air temp sensors, much of the warm up benefit is negated.

If it's 20F, you bet I'm going to let the bike warm up a few minutes. But not much more than that. You're not going to seize an engine starting it up cold and driving away like you might have back in the 70s or earlier.
