Thanks KCW, I've had a lot of fun building this bike...like the exhaust, that fender on the back is an 18 dollar trailer fender from Tractor Supply and that was fun figuring out how to mount safely and securely. I at least have a proper Miller 212 Mig welder...no tig, yet. I can get down pretty low on my temp with small wire and weld pipe OK, but its a lot of short bursts and like you...following up with a grinder and a sandpaper wheel. The plate I built for the rear fender...that weld looks like complete and total poo poo, It was a pretty thick plate and welding onto that swingarm tubing I didn't want to burn through it so, again, short shots of welding and I couldn't really get my grinder in there to it too good...so, its a little added charm in an area you really can't see.
To your point about the head covers...I kind of like them on there, I like that touch of chrome...something about the shiny gleaming chrome and the rest of the stuff cobbled together just "works" to me. Even the galvanized rear fender, I think im going to leave it alone. One thing I have seen people do is remove the battery box and open all that area up and really detail out the rear shock...that is kind of cool, and I might explore that one day.
