Hi. My crankshaft rod head bearing is worn out. Does 152qmi engines must have piston wrist clearance in rod? Can it only have play at PISTON-Piston wrist connection and Wrist-Rod can be fixed in place?
Typically you don't with most GY6 125/150cc for 171cc bolton. However for 190cc you want to make sure open your crankcase and measure make sure it's has a clearance bore opening of at least 65.2 mm for the outer skirt of cylinder ssp-g or Taida is 65mm. But if you're talking about the sspg kit you need to complete crankcase swap it from A block to a B Block, it needs to open if almost 65.2 mm to fit a 63 mm cylinder jug in there. Even if you can bore the A-block to be 65.2 mm the cylinder stud is 54 mm will not fit a 57 mm cylinder jug here in video. It's best to get the complete crankcase assembly however its only made for a long case A-block conversion or B-block longcase.
So quick question on these big bore kits weather its a 61 or 62 or 63mm cylinder with 54mm bolt spacing is it recommended to put a spacer on with gaskets on both sides to prevent hitting the top of the cylinder, or should you just run them away for precaution to be on the safe side.

Piston silindiri taktım fakat zincir bol geldi nasıl oturturum yerine
whats the original piston cc from this engine ?
either 125 or 150cc, I suspect 150cc
do you need to bore the case out for it?

Bro r pinoy u look same face like pinoy
yes for a real 180 big bore kit
that is not a 180 cc big bore kit. 180 has to have case shaved in order to fit.
Is is, engine displacement 63mm bore with standard stroker = 180cc. Find it here ncystore.com/ssp-g-180cc-big-bore-power-kit
You need to slow down stop talking too much and then you wouldn't be such a bad GY6 mechanic pay attention what you doing
