I gave Castrol Grippa 60s a go just because i had some but went back to using thick pump grease. The Castrol Grippa turned to liquid with the heat from the engine, i recommend a grease that is temperature stable and can withstand a reasonable amount of water, hence me using pump grease. Maybe copper grease could be better, but isnt as thick and water resistant, but i pressure wash my bike.
If the shaft is good the JT sprockets many times has to be tapped on with a mallet, once run they burnish themselves in for a perfect fit. Later George
