Nothing like a proper refresh. This 07 kawi head came in smoked. Got a proper treatment. M90 seats all around, 4 modded bronze guides,4 pro-x titanium’s , fly cut, v***r blasted. He sent in his cylinder which was a Temu special, you know we had to get him right, nice cylinder works cylinder kit, vertex piston and gaskets.

Needless to say, this customer will be solid for a long while. If you’re gonna spend the money, build the head right. You won’t regret it !
