    Who has any experience with the Grubee Skyhawk GT5A? Is the quality better then the off brands? Thinking about getting one for my second build.

    Pleased with mine Jeff. 30mph right out of the box.
    Improved to 38mph with only some careful sanding of the head.
    Vibrations are not bad. Mostly Allen head fasteners.
    Head studs are good, other studs fair (better than the other kit), replace all the nuts.
    It was a plug and play. power is much better than my "No-Name" engine.
    Air filter on all of these is poor if you ride in dust or dirt. Get a better air filter.
    Stock carb was jetted close (slightly rich, lowered float to tune).

    Far from a Honda or my beloved KTM, I am still pleased with it after a dozen tanks of gas.

    Thanks Steve the stock carburetor will never be installed. Will be running a Mikuni VM serries 18mm. My second build is going to be my hot rod. LOL

    Just picked up a whole kit with everything I need to mount for $145 shipped. Includes rear sprocket, chain, throttle and so on. Best price I could find.

    I'd really like to try one of those PK80 motors from ozarkcruisers. They seem pretty solid for the money. They come with a 40mm engine mount so they would bolt right on to my skyhawk frame. I've heard a lot of good things about em, as I have for the skyhawk motors as well. A decision to be had in the future.
