Rev limiter

[bshinn]

Want to remove the Gov from my daughters kart, but not quite ready to have her running around @ 7K rpms. Would like to electronically govern it until she gets a little older. Any suggestions?

Due to valve bounce in a stock engine, it will only get to around 5k anyway but, IMO, you'd be best to leave it alone for now

For a cheap solution you could buy one of those really cheap electronic shift lights they have on ebay all the time and wire the light up to a relay which trips the kill switch. I did this on my Sidewinder buggy with a motorbike engine but it's the same principle, cuts spark when you reach the limit then engages it when it drops below. It's also infinitely adjustable so you could lower it if other kids drive the kart.

Not a bad idea, but will it work with an OPE engine?

Staying with the stock springs so flywheel should not be an issue, will upgrade at a later date. More worried about her lead foot. The shift light relay ghetto fab solution seems to be a good option. will research that.
