Break in new cylinder
-
@irongamer727 Refer you to my first post, but Jens method sounds legit to me.

@calum oh sorry I didn't mean during the break in. Let's say you take your Dt out for a ride. How do you warm it up? Idling? Calm riding?
@irongamer727 What I did, was leave my house. Start the bike up, always needed choke, let it idle. Walk back to my gear, put my helmet on and gloves on, by which time the idle was drastically dying and I needed the choke of. Ride off. I never rode it hard until it was up to temperature, but the RE's don't have a temperature gauge.
Put it this way, these are commuter bikes, in stock form they are designed to be ragged from cold, excuse the expression.
They are meant for jump up idiots, for which I wasn't one, to go on and obliterate. They were designed to do countless miles with minimal maintenance.Always Originate, Never Pirate!

@calum pretty much sounds like my every day routine
@irongamer727 I always warm mine to a warm radiator then I start revving to clear the smoke then by the time that’s done and I’ve pushed it up the garden it’s good to ride just put your hand on the rad and if it’s like warm you can start revving to clear it out it avoids fould plugs, as for break in there’s a lot of bull sorrounding it with my bikes I always do heat cycles then I take it easy not for a specified time or mileage usually two rides then I start riding normally but no redlining and then it’s pretty much when you feel comfortable riding it properly it’s all down to you but just remember hard break ins are bollocks and so are soft break ins the answer is in the middle you don’t want to lug the engine but you also don’t want to create excessive heat and wears during the break in, that said on my project bike I just finished on it’s first ride I rode it normally up to redline no issues it’s only a 70 so not a beast so you kind of have to ride it like that I only paid 50 for the barrel and head piston full endgame gaskets and silicone sealant so it’s not exactly an expensive thing to have go wrong I wouldn’t ride a dt or any other bike like that though

@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. -

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

@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.
@irongamer727 I did on the stock barrel just cause.
-
@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?
@Irongamer727 https://youtu.be/WwFUzgr2xnA there it helped me a lot

@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

@declan haha was that during your break in?

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

@irongamer727 nice one bud.

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

@jens-eskildsen sure will

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. -
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.
