dude one word-Lectrons!!!!!
My bansh has similer mods and I have 36mm. Lectrons
As far a ease of tuning. NOTHING is easier!! Theres not even jets to mess with. They have adjustable power valves. So all you have to do is turn a screw to go rich or lean.
Give Dennis Packard a call. His sight is packardracing.com
He custom machines all his Lectrons to your ridding style and mods.
Seriously, Lectrons are the only way to go. there sorta spendy, but well worth thew money!!
All other brands are just a larger versions of the the same P.O.S. that came stock.
