I have a factory service manual for my 87 750(H) and it states that the bike should have 34mm mikunis. the bore on mine measure right at 30mm.is this right.The manual also states that the carbs should have #130 throttle valves which they do. the bike was under carberated when I took the motor apart and need to know what would work with mild porting(already done). also has anybody used a big bore kit on their 750,if so which one and did you use the stock rods or something better.

you might have 86 carbs which were 31mm.....if you've got mild porting and want to do even more engine work, definitely ditch those 31's. get a set of 36mm slingshots or flatslides, at least....
