need some advices, i want to buy the full gasket kit from Cometic... now, this kit comes with A HG 87.5x1.2mm, and the OEM is 86mm bore size... this 1.5mm gap is confusing me... too risky or it doesnt going to affect? should i buy it or find another HG size?

ideally your hg should be the same size as your cylinders bore. being .5mm larger is acceptable, not larger than that.
