need help !
 

I have questions about the engine XCEED DS4 EM .21
1, the head shims seems to be 0.30 mm if i use 25% i should add one 0.1mm head shims, I should add the shims before i break in the engine? All engines are the same?
2, the manual reasonable temperature series 110c, but inability i have to leam 130c Normal performance, very stable, what i should do?
Very lean LSN, HSN is on the rich side, will breaking the engine? But Gear shift very soon and Good idle faster pickup .
thanks a lot:D
