Hi , 1st time on here . I bought an 07 pampera 450 , 6 weeks ago . its only got 4500 km on clock. It has a bit of a miss ( stutter ) in the low to mid range , when not under a lot of load , starts well , idles well , great hard thru the gears and top end . the local honda shop said it was running a bit lean and ordered a 140 main jet from a 138 std . theold plug was a brown colour which I thought was ok . Anyway they changed it over and its no different . Two people have since said it shouldnt be main jet , more like needle seat height or possible pilot jet .
Anyone had similar problems , just want an easy fix . Dont want to mess with carby too much and wreck the rest of the range . has a phf 36 dellorto carb.
