Break in new cylinder

[Irongamer727]

@declan Ye, well I can monitor the temperature exactly since i have fitted a gauge. (Best choice I have ever made) so overheating shouldn't be a problem. Just extremely frighten something bad will happens during the break in.
Like it won't get enough oil.
Running to lean etc.
Even though I have almost everything covered and fixed.

@irongamer727 By the time you notice any change in temperature, the damage is going to already be done.

Just ensure that the oil pump is bled and pumping oil. Since it is not a closed system, I dont' bother bleeding it, I just add oil into the petrol and run through a tank rich on oil

[Irongamer727]

@calum I have not messed with the hoses to I should be good. Wounder if I should turn up the pump just ever so slightly.

[Calum]

@irongamer727 I did on the stock barrel just cause.

[declan]

@calum yeah I did the same if you want I can link you Calum’s video so you can run the same settings as us two?

[declan]

@Irongamer727 https://youtu.be/WwFUzgr2xnA there it helped me a lot

[declan]

@Irongamer727 and don’t worry about Fouling plugs if you add oil to the tank as well as autolube I was running 165ml of oil to 5ltr of fuel aswell as enriched auto lube for months with no issue I was a bit paranoid I don’t recommend doing it though

[Irongamer727]

@declan haha was that during your break in?

[declan]

@irongamer727 I never recorded hours or miles so yeah and also after break in @Calum made me stop lol

[Irongamer727]

O my god what a relief! Athena is up and running! Jesus Christ I have never ever been so afraid of something going wrong. Hopefully the worst part is over. Still afraid a circlip will come loose and mess EVERYTHING up. But, I've done my best, bring on the summer

[Calum]

@irongamer727 nice one bud.

[Jens Eskildsen]

Hopefully you will keep us updated with how you like it, as you clock some miles on her

[Irongamer727]

@jens-eskildsen sure will

[Irongamer727]

I'm getting more acquainted with the brake in procedures. I've always thought you couldn't be too careful running an engine in. Obviously I was wrong. The fact that idling can glaze the bore scares me! I mean you need a good 20 minutes to bled the cooling system of air.
Guess a moderate run in with a bit of variation of revs is preferable.

[Calum]

I always thought it was giving it too much chst before thr rings have bedded in causes glazing.

Either way, get it runing and put some miles intonit before hammeringnit. That's my advice. Two strokes don't last forever so it's a moot point if it lasts +-1k miles. The main thing is getting that fueling spot on.

[declan]

@calum 20 minutes to bleed the cooling it only took mine a few seconds

[oldman]

You should warm the engine thoroughly to make sure thermostat opens and gives full flow to water passages, otherwise pockets of air could remain

[Irongamer727]

@declan after 20 minutes there were still air left. But at that point I felt satisfied.

[Calum]

I don't think I've really actively bled the coolant system on any of my builds. Fire her up rad cap off, just top it up. Quick blip round the block top her up jobs a goodun

[Irongamer727]

@calum works for some
