well crap i cant find a yamaha part number..it doesnt even show a gasket in the schematics...maybe its just rtv sealant or something..on all the blasters ive seen it looks like there is a fiber based gasket between the halfs though..hmmm Genuine OEM Parts :: CRANKCASE Parts for YAMAHA BLASTER 2006
you must be right..ive never had to split cases on a blaster ever...what ever they are using from the factory appears like a gasket though.must be good stuff haha
