Try a boost bottle, one stopped mine hesitating at mid rev range. If it don't work, take it off. First and second gears are where the fun's at round town, IMO.

Not sure, but after fitting NOS barrels/pistons/pv's it all went away.. maybe a little tired engine cant pick up fast enough to make a blast in first, but seem ok in 2nd? Just a thin theory.., could be a number of other reasons..

US RZs have different carbs than the rest of the world and the boost bottle wont fit as they are too tall ( the carbs )

Boost bottles are in my personal experience not any good... crossover tube works the best.

Its the silver "U" shaped tube that connects both inlet manifolds.
