Anyone using one of these from PM? Looking for a balanced one for an RB. Would be good to get some feedback before weighing any money out.

I'm using one with an Avanti kit but running in so can't really give an opinion . It certainly looks and feels well made though

I took it to CS engineering to check for true before fitting and Chris was impressed ,so that's a good start :D

I'm sure I paid less than £300 a few months ago

Great little cranks those. I use the 62/116 in RB250 builds.

Worth checking the clearance on the big end shims, the one I had was tight and needed opening up.

The shims go either side of the con-rod. They are there to stop the con-rod rubbing on the crank flywheels. If the flywheels have been pressed in too far onto the crank pin during assembly the clearance between the rod, shims and flywheels will be too tight which could cause a seizure when engine warms up. The clearance cannot be increased by a regular home mechanic without specialised tooling.
