So I bought my Keyway F-ACT in March 2011, since then I've put almost 10k miles on it. An issue I'm having with it is that it wont stay running when I first start it up, until it warms up from driving it, and the other issue is that when you take off right after starting it, it gets up to about 7500 to 8000 rpm yet is only going about 15mph. Anyone have any input on what the problem might be? I'd also like to go a little faster, I generally max out 40-42mph on flat surphace without any wind. Thanks for your help in advance everyone!!!

How long has it been since you changed the spark plug?
Maybe try a new plug.
Maybe some new weights in the variator too.

check the electric enricher on the carb...adjust the idle mixture screw....of course after this many mles the plug should be new...engine compression should be 155 lb + - 5 lbs....hope this helps get you started
