GX390 with KX65 transmission on shifter kart

[DopamineAddict]

It works. Built from absolute scratch from a junked KX65 and clone GX390 generator engine. Still dialing in the gearing, but it's close. Anyone try this before and have input and/or questions?

See it in action:

Dang!! It looks good. Is it not a bit top heavy though? I would also definitely get some cover for that chain that is spinning right next to your face!

Welcome to the forum

DO NOT even ATTEMPT to do much testing with those Front tires.
I am very serious. They will fail almost immediately.

Other than that and what ^ he said. Nevermond i see the plywood. Cool Concept I like it.
Welcome to the Forum.
[edit]
Oh and maybe move the brake pedal to the left. that looks cumbersome.

OK. I see plywood now. A mix of build timeline pics there. As long as it is covered, you are good to go

Yea when we test it we throw on the plywood as our temporary shield from the sprockets and chain. As for the front tires, they are also just for low speed testing as well. I wouldn't trust my safety to anything purchased at harbour freight.
As for the pedal setup it is going to be gas and break on the right side, and clutch pedal on the left (not mounted yet), like a standard trans car because we have the 6 speed transmission. Got some cable equalizers to set up a sequential shift handle kind of how you see in the rally cars.
I suppose it is slightly more top heavy than average but it's wide enough, and the frame twists enough where you will just slide out still instead of flipping. With these tires anyway.
Thanks for the welcoming!

Albeit this is the intro...Welcome...
I would like to hear and see your conversion topic of that transmission...
They are a hot topic about here... And not alot of conversions done...

Thank you. I was thinking with that much fab knowledge you probably knew that.
and the pedals (duh) of course! I forgot about the clutch.
Carry on

Start a thread in the build log section and maybe tell us how you mated the trans to the engine. A lot of us would like to know

I was thinking to use motorcycle transmission, I was in doubt if that is possible and now I know it is, thanks. Nice job!

 

[Holybeen]

Definitely want more info on the trans. I've got a few spare mx bike parts laying around
