Hello everybody.
I installed a Vito's stroker +3mm crank with spacer plate in my dt's engine and I would like to correct port timing myself.
Dt and Blaster engines are almost the same(same bore,same stroke) except some details like power valve etc...
At TDC everything is ok butt at the BDC the piston crown is 3mm lower than the bottom of the port windows.
Should I grind all port windows bottom about 3mm to match up the piston crown at BDC?
here is a photo with the piston at BDC
