Thanks guys, this is the kind of input I'm after. I'd like to do something with the engine in the next two weeks, so a bit of a wait isn't an issue. I just need to come up with a plan so I can decide what to do with the 6.5 i have and the little one's mini shark. Even if i replace the driven and shelve the 6.5 for now and start her with the 3 hp and a centrifugal, i'm ahead of the game having a spare engine and "trans."
Metal, what i visualize from your description is that the "right" GY6 for a kart can go in a frame that has a rigid axle attached to it? That's where i'm lost with these, i can't figure out if the "transmission/driven sprocket" portion has a pivot like a swingarm that is going to require a floating axle or a chain tensioner system.
I also gather that 150cc versions of these start out with around 8-10 hp? I watched the comparison and saw that the 250 really just has a stronger bottom to the power band (comes with teh cubes) up top it looks like they're pretty even. I'm a big cube, long stroke torque junkie if you haven't figured that out yet (comes with being a Pontiac guy). ))
I think my perception of "fiddly" seems to come from just the amount that are out there and the no start issues caused by old gas and bad wiring connection--that and apparently there's a lot of adjustment that can be done with the CVT--is that where the variator and rollers/sliders etc come in to play????
BTW, I also have an old, but never used Peterbuilt fog/driving light set-- 2 55 watt lights, relay, switch and harness. Is there a particular amp output level i should look for?
