GT750 Crankcase Bypass and Oil Pump O Rings Q

Anyone have the dimensions of the O ring that fits between the crankcases at the water bypass please? Pretty sure there's not one in the gasket kit I have.

Also.....did I read somewhere that small pattern O rings for the oil pump are sometimes a fail and it's best to stick with Suzy ones?

Thanks, Drew.

09280-12002 is the bypass O ring you need to buy, I buy all oem orings since its easier to simply go to the dealer. Unless its one thats NLA.

See if you can order OEM oil pump rings as well. I used pattern parts on a recent rebuild and the pump leaked. Turned out that the o rings were too large and one squeezed slightly out of place and was pinched between the pump and spider allowing oil to seep out slowly. Very annoying but easy to fix - and avoidable.
