nice! but not easy to do so.

Just to share some knowledge and finding about New Car's engine breaking-in. There are 2 totally different idea:-
1) follow your manual book (smooth running-in)
2) strong approach running-in (refer link below)
I combined both idea, first 800km running-in mild (smooth) and then follow by 200km take it to 5k-6k rev and more than 120km/h, once reach 1000km, go for first service and change engine oil (request and pay for it), since after running-in, a lot of fine particles inside the oil.

use super glue to glue the nut cover, since u hardly got chance need to open it up.... if really really need open it up, then only break the cover to open the nut! hahaaa....

unless you are really hardcore guy, i can't find a reason to upgrade it.
