    Gore?

    Head had indentations around machined surfaces. Power valves would not slide freely in cylinder. Power valve machined surfaces in cylinder appeared to be bead blasted as had the whole cylinder except the head sealing surface. Required using old power vavle actuating hardware.

    Well worth the time and money.

    Took a little bit of grinding on the case to make room for the new cylinder. Be prepared to have to flush the bottom end if your not splitting the case. My kid noticed the difference immediately and said it has way more bottom end. Mild jetting will need to be done as it was a little bit lean after instillation.

    Worth the money is you can afford it.

    Very nice kit. Makes a big difference in the low end.

    Kit is great improvement to a stock 125. Just remember most kits do not come with wrist pin bearing so be sure to order one separately
