Well, 'agricultural' is a matter of perception. I'm confident the throttle bodies etc are fine. The sprockets have been tweaked, too.
To be honest, I'm not sure this is the bike for me. I've already managed to scratch the paint on the offside pannier *and* nearside mirror, getting it in and out of my back yard. This on Day One!
I fear it may be a bit too big and heavy for me.
