Heat cycling

[06redrevx]

what are opinions on heat cycling a new sled? Is it worth it? Seems like a good way to foul plugs?

New sled-new engine going to trade at the end of year= Ride it maybe a little more gentle for awhile or follow break in.
New sled- new engine- going to keep this sled awhile- heat cycle
Newer sled-Just replaced jugs, pistons, bottom end or motor I put together=Heat cycle.
Old Sled- Just replaced jugs, pistons, bottom end or motor I put together-Send it, if it blows, it was just not to be.

anybody have any data that backs up the need to heat cycle? sounds like an old wives tale.

It’s definitely an old wives tale.

Just run it.

I’ve seen a handful premature failures and exactly zero of them would have been prevented by “heat cycles”

Cold siezure is just that don’t hammer it until it’s warm.

If there’s something wrong with the mechanical parts it won’t go away with heat cycles……..

The only heat cycling I’ve ever done is loading the sled on the trailer at the dealer and whatever moving the sled around the yard needs done before the snow flys. Then I just warm her up and let her rip come the first ride.

Late fall, I usually do some hot laps around the yard. Does that count for heat cycles? ? Get some seat time in while waiting for snow! And this year, still waiting for good snow, more hot laps. Lol

Warm the sled up to operating temp and ease into the throttle a fee times to get pipe heat in it before u flog it. Thats about it. New or well broke in I treat them the same without issue.

That’s always the way I’ve done it. Thanks

What is “heat cycling”?
Ive read it on forums but I don’t know what it is or why it’s done?

I guess it’s warming the sled up but not riding it?

That’s exactly it; similar to wiping before you poop.

I'd heat cycle it once on a new build. Just make sure nothing is unhappy.
I had 1 seize at idle that I'm sure would have been more destructive at WOT. Ring gap was bad, and my dumbass just threw it together since "it's a kit, it'll fit!". Damn right I check ring gaps and measure the pistons and cylinders no matter what now.


After 1 good start and cool, it's just let it warm up and smash the throttle.
