New Engine Break-in (part 1)- Taiwan beauty Part 4

At the beginning of this I say that I already made a vid about Engine Break-in...but that it was 14 minutes....guess how long my new Break-in video is? Haha, yep....14 minutes on the nose...so I broke it into two.

@stoneageman18 I second that

mad thinking no one has wrote on this in like 1200 days. o;o. Braking the system xD

four stroke engines have many more components than just pistons. Cams,tappids,rocker,gears etc. Taking it easy helps to mesh them together in uniform. Riding like you stole it scars all those components. But everyones an expert these days. Im sticking to a nice and easy running in. call me old school. I say make friends with a good mechanic they know ;) still gave 5 star

That is interesting. Will look up Motoman. Thanks amigo.

We never sustained high rpm during break-in because it was said that the excessive friction could anneal the rings. Not sure how much of this was true but certainly engines that were worked hard during break in seemed to have more power and really did not have short lives and high oil consumption.

Mototuneusa makes interesting reading, I have run engines in both gently and hard. Many years ago with performance cars we learnt that you should give the engine the odd rip from the lights to get to get the combustion pressure high in order to seat the rings.

when breaking in an engine using moly rings you must beat the piss out of it for the first 50 miles otherwise if you pussyfoot the engine you will glaze the rings and they will not seat properly... you wont burn oil you will just have a higher than normal amount of compression blowby associated with the cylinder walls glazed.

Well I think your wrong because these bikes are DESIGNED to take this punishment and above(the red line is the point until its safe to push the engine) and he is right about the piston rings because the piston rings expand when they're heated.

thats what i would think even though the method mordeth13 is suggesting will break it in faster, as u said the scatches on the engine will be worse giving less preformance and changing the sleeve is not a fun

125 cc 2strokes also need replacements..

I ride a Cagiva Mito, also a 125cc 2stroke. It needs its piston replaced every 8000 miles or so. It's just the wear you'll have to take into account when using a 2stroke.
