After two 2013 DT300i scoots took about 7500 miles each to stabilize, I think you have longer to think about! Now, neither consumed any oil in that time, just used less and less fuel until that number stopped going up. Started about 65-68 mpg and topped at 73-75 mpg. Oil never varied. Same for a Like200i and a Yager 200i. Same distance just bigger mpg!
I see your point, it is true that different parts of the scooter have different break-in periods.
But regarding my specific problem, the only part that matters is the engine (assuming there's no oil leak, which i have not yet found). Or even more specificly, assuming i have it right, the problem is originating from one of 2 parts of the engine: (please someone tell me if i'm wrong).
*Either there's a problem with the fitment between the piston ring and the cylinder, which will allow oil to make its way from the crank shaft to the combustion chamber, and then burn along with the air and fuel mixture, resulting in oil loss + excess fuel usage + HP loss.
*Or there's a problem with the valves seals, which will allow oil to enter the combustion chamber from the cylinder head area. which will also result in the same symptoms.
The main risk from not breaking in the engine properly is the former case. (the valves seals don't really require breaking-in as far as i know).
And according to many sources and people i've talked to, it's a pretty definite consensus that the break-in period for the piston/cylinder is at most 1000km, and as i've mentioned earlier, it seems like the majority of proffesionals these days claim that it's actually much less than that in modern engines.
so 1800km (actually i'm on 2000 by now) should be more then enough.
P.S.
if anything i have written here is wrong i'll be very glad to know and be enlightened.(seriously).
