Tips on selling.

So I put my first gas bike kit on a extra(free) standard mountain bike to learn the process and the risks before putting one on my nicer bike. I'm now trying to flip my current bike to fund the next build. I've put about $230 into what is here in the ad:

I'd be happy to get $350 for the whole thing, is this unrealistic? Too high, too low? Any tips on selling?

I'll just be patient about lowering the price. I imagine I'll have more luck when the KU students come back from summer break.
