They really do handle well despite their weight. I use 20wt fork oil, fox gas shocks, and avon roadriders, made the bike feel 100lbs lighter. A fork brace really helps the front end feel stable.
Looking good so far Allen. But.........what's up with those pods? I understand trying to find the proper airbox for a restoration can be a rest PITA, but I'm gonna say emgo pods may just give you all sorts of problems.
That throttle cable could be a couple different things. Check the carbs first (make sure they snap back), then hook the cable to the carbs. Try pulling the end of the cable by hand. Then hook it up to the throttle assembly and check it again. Could be the carb springs, dirty cable, dirty throttle sleeve bent throttle sleeve, etc.
Bike is looking great, and yes even a little bend in the cable can cause it to stick. A new one is a good idea fro sure, cause first it sticks then it breaks.
