Break In Process

[flattrakker]

ill be getting my shee back together shortly and would like to know how you guys break your engines in.. ive heard ppl spend alot of time doing it right and some dont and hop on and run... id like to take my time with it to increase the longevity of it.. what do you guys say?

[theshee]

Give it 3 heat cycles, and I would ride it easy for just a little bit (like 10minutes) of the first ride. Then ride like you are gonna ride it.

[flattrakker]

heat cycle? is that like running it on the stand til its warm then letting it cool all the way?

[theshee]

Yeah, just sitting there idling with brief easy revs. No real high revs though.

As long as I have 2-strokes, which included my banshee that I bought new in 2006, I ran it for about 30 minutes at various engine speeds without hammering it, after that, i ride it as if a stole it!!! I also premix a little richer as always for the first 2 tanks of gas. Never had problems.

Yeah,

Two to three short rides (20min. or so) never reaching more than 1/2 throttle and completely

cooling between. Then.............ride the hell out of it.

Are your pistons cast or forged?

The first startup I just let it set and idle till the radistor was just warm. Wait till I could not feel any heat in the radiator and repeat two more times. Then the forth time take for a easy ride, not winding out to far, for about 10 minates. For the first tank of gas try not to lug or rev out to far. Just put some time on the motor. Remember everthing is tight and it won't hurt to let it work in a little. I have done the two heat cycles and ride it hard after that but it was on a dirt bike. I don't think the rebuild cost as much as the Banshee and I was younger and more impatient. Good luck

If you have forged pistons you need to warm up your engine befor you hammer on it anyway. After its broke in.

[Snopczynski]

with forged wiseco pistons I do this:

 

2 idle heat cycles.

 

1 more low rpm drive cycle arund the neighborhood.

 

Then I ride it like it is stolen at the dunes. Just stay off the very peak rpm, dont do anything extended past 2-3 seconds at high rpm either.

#1 Couple of heat cycles.

 

Next and most important step.

#2 Check to make sure the Head, and Cylinder nuts are still tight

 

#3 Take it easy for 5 gallons

 

#4 Check the Head, and Cylinder nuts.

 

#5 Ride it

I break my engines in on an AC engine dyno using a load profile I refine pretty much every time I do it. I have been fooling around with some no-spark motoring techniques that have really improved ring seating on my nicasil bore engine. :geek:
