So I'm happy to say I have just bought my first Kart, a 2015 CRG with a Yamaha KT100SE motor and direct drive.
It's an ex race kart in fair condition for the price.
The plan is for this to be my winter toy, as here in Finland our winters mean no motorbikes or pretty cars between November and April. So I will be spending my evenings drifting around the factory at work.
The direct drive rapidly became a problem. I built a starter without any problem, but the act of actually getting her off the stand and into forward motion eluded me. It's basically not possible to use it alone, which is what I wanted. So I contacted a local firm and they supplied me with a Raket 120 clutch which I fitted yesterday. Works beautifully, in that I can easily operate the kart alone. Noticeably different to drive though, you can really feel the disconnect when you put the power down. With DD, you can easily provoke the rear under braking or on corner exit. But its a good compromise.
The problem is when I came to stop, because previously with DD, I killed the motor simply by slowing to a stop. Now with the clutch I have no way of shutting off the engine.
I don't want to keep yanking of the HT lead whenever i'm done!
Can someone explain simply how is the best way to safely stop the engine?
I am pretty handy mechanically but i suck at electrics.
Many thanks!

You need to source an ignition switch. Any jarring shop will sort it out easily.

As for direct drive… much better and encourages better driving. Not good for you to muck about drifting, etc.

I raced go karts 100cc direct drive. Many weekday training sessions I was on my own. Starting it was a piss of cake. No need for anyone to push start you. Prime the carb, hand on steering wheel, lift the back with the other hand run a few meters drop it and jump in hitting the accelerator. Sounds complicated but once you get the knack of it it’s easy.
