after changing the plugs, changing the oil, i decided to install skydocs shim kit before i synced the carbs using the carbtune pro i got from zane. thanks again zane. 3 carbs, no problem. last carb, DOH! i must have put the nylon nut ever so slightly wrong, and SNAP! broke a diaphragm housing. lack of patience i suppose. only had about a good 2 hours of clear weather before the rain came this weekend. i found some new ones on ebay. so i bought 2, 1 for a backup. and i got 2 needle kits, just for spares.
