The most common mod for this is to fit a 2RS version of the bearing.
The debate on popping out the inner seal or not will continue until the end of time!
Thanks Ian, also the oil pump spindle worm drive which fits onto the timing side of the crank does this have a washer behind it(touching the crankcase) or does it go straight onto casing?
Hi ron, in attached photo see where im pointing where the t.side crank comes through the casing there is approx 1.5mm gap around the shaft. When worm drive is installed onto the turned down keyed part then buts upto the shoulder does notthing go behind here
