Super tryke rebirth

I didn't know that. I'm not going to to tinker with the governor, it runs plenty fast the way it is. So the will the 44 driver work with the 40 driven?
yep, simple as pull the 40 driver off and swap the 44c driver on. I just never had any luck with the 40 drivers and it seems i'm not alone at all. It didn't matter if it was a china knock off or genuine comet, no matter how much i sanded, smoothed, de burred, lubed etc, it would hangup within a hour or so. If you leave the gov stock, then you might have better results. I yanked the gov off my 420 and do blast it up to 4800-5200 ish from time to time, so that could be why i have more headaches??
