Crank balancing

I built up a Shadow some years ago, the engine parts being from a number of sources, but I never had the crank balanced, I naively considered at the time this was a racing refinement, not really necessary for the road. The bike never ran well, slow, vibrated badly. So I have decided this winter to totally pull it apart and check the basics, crank alignment and balance.

After reading about Paul Norman’s crank assembly balancing experiences on www.racingvincent.co.uk I am pretty sure the balance is going to be a similar challenge. I too have Carillo rods and may have to look at "adding" weight to wheels opposite to the pin, rather than further reducing weight near the pin.

Paul’s work was undertaken by a specialist via The Maughans who inserted heavy metal plugs into the wheels. My assumption being that these inserts would be a tungsten alloy, which I understand is quite machinable, but I have been unsuccessful in sourcing a supply of small pieces of the this alloy. Darts are a bit small and the only other item using tungsten I could think of is A golf clubs head!

Anybody been in this situation or help with a supplier of tungsten alloy and best engineering practise for added the weight to the flywheels
