What is the port size of the stock carbs on my 03 vt750? I want to build my own intake and switch over to an appropriate size single carb. I got a 34mm mikuni but I´m not sure its big enough. I dont want to tear it down til I´m ready to make the switch!!! (missin´ seat time is a NO NO!!) Also I´ve seen a couple of spirits with a monoshock conversion, I would love to do this to mine! Any suggestions on what shock length and spring weight to use?
