Hi all,has anybody had a GP 150 crankshaft machined at the oilseal shoulder so it can accept the wider NU2205 mag bearing?
Basically,i have an Indian GP150 crank that i want pressed apart,and fitted with a Mazzuchelli Vespa Ape rod to go in my old school Suzuki 225 motor,but i want to use the wider bearing.
The oil seal shoulder on the 150 crank measures 13mm,and i need it to be machined down to 10mm.

Hi guys,thanks for the replies.
I have no problem getting it done (local lathe wizard on hand),just wondered if anybody else had the same work done,and was it worth while.
