how does that thing pull with a full load on it? ive got an identical weedeater motor that "id like to build simething with. good job on the build too!:thumbsup::thumbsup::thumbsup:
They pull about like you'd expect from a 23 CC two stroke.. :laugh: This bike does like maybe 12 or 15?? Never GPS'd it yet.. I know it will pull 140 but it's like maxed out.. It does OK doing several hundred circles in the driveway, cement circle drive slightly down hill, build rpms, hit the dirt road slightly up hill, start losing rpms.. But with the carb rite, and making power I can drive UP the road towards the dead end, which is a long slow slight uphill grade, drive all the way to the cops house and turn around at the top of the hill...
But level ground but soft yard / grass.. anything not hard, it won't pull you.. It is really more for a 40 pound kid..
I also have this one geared for about 5 and it pulls pretty good on solid ground..
I am planning on yanking the engine, screwing with porting and larger exhaust to be able to build more torque, and see what I got for stiffer clutch springs..
I believe Koritz actually builds the engines.. I've had dozens of them.. many many different names.. This one has an actual aluminum ID badge that says Koritz Corporation, made in japan.. And this one seams really well built.. Everything tight and clean..
Plus I can see Koritz shipping them into the US, then all the US companies put their name on it.. I know lots of (John Deere) and stuff like that, is actually BUILT BY, Koritz...
I can't fathom 38 US companies all building the same engine, then shipping them to japan, to an actual engine manufacturer..
