While researching twin plug heads I came across this little tweak for cylinder head studs / nuts.
APE make a kit for the 4 cylinder bikes and 4 of the studs are interchangeable with the stock KZ items. Ideal for anyone making a bit of extra power – or just plain head gasket reliability.
I’m trying to talk them into selling the items we need in sets. As they already make them, logic says it’s just another sales outlet. However, big companies don’t always work like that ! We’ll see.
