  • Anyone looking for me or trying to send me a message, I'm hardly on here any more. But if you have a Facebook page I'm on there all the time. Just search for Charles Mosley Minidragbike on Facebook and you will find me, and send me a message.
    Would you build a head for an GX-200, 32mm intake and 28mm exhaust, ported on both sides? If you would build it, how much do you charge?

    My email is, If you could just email me I would appreciate it.

    Had a few questions for you im from ohio and run karts we run a clone or honda gx200 stock apearing anything in the inside is game. I was wondering what you thought about running 32mm intake and 28 exhaust valves for the head with a full port and polish . and head milled to make it a 14cc so i was wondering what springs you think would be a good match also planing on running a 308 cam with the 625 sock apearing carb billet rod or arc ? any helps would be good thanks . looks like you do alot of good work!
    I posted a question for ya in the clone engine mod section under wanting to build 25+hp clone. Just in case you don't see it. Thanks man.
    Yes all engines require so much TQ for sealing purposes. But I can tell you what that engine takes. But looking at the size, it has to be around 15 foot pounds.
    Hey Wildman, hope you are having a great Memorial Day weekend. I am, playing out in the shop all weekend. Will probably put new rear tire on the trainbike and take it for a spin too!
