400 or higher engine any make or model

[RobRacing]

I am looking for an engine that is 400cc or higher with electric start. It can be from any make or model. Trying to see what my options are, I am building a mini dune buggy. Show me what you have and we will take it from there.

I have a nice 400ex motor. also have carb & electrics for it. it is stock with no mods & no smoke. runs very strong, but might need a clutch in the future.

How much for the whole package (carb electronics everything to make it run) Do you have an pics?

[YTZ250#1]

if you want the carb ,electrics,& head pipe with the motor. I can let it go for $650. I can get pics in a day or 2.

ive got a complete 440ex with port job, kibblewhite valves and spings, a seat job, stage 1 cam, polished valve cover, 13:1 compression, full harness, build done 6 months ago with around 7 rides on it. before the build the motor was completely stock. its still on the bike so i can compression test it wednesday then its coming off. i can send a video of the compression test, and let you hear it run.
