It’s best to port the engine especially if you have a 1973 or earlier engine. Starting in 1974 and even mor so in 1975 the engine was factory ported to boost hp. The Z1 was steeling the show so Suzuki felt it necessary to crank up the big triple. Putting the 1975 model into the 12 second qtr mile range. A little more porting and expansion chambers pushed the water Buffalo past the Z1 into the 11 second range.

The sprocket cover plate should have an o-ring to seal in transmission oil. The driven shaft cover is needed for oil retention as well. A sealed bearing would not work there.

This was years ago, but if you look closely at the video you can see a black ring around the bearing on the block It appears I must have installed the O-ring off camera.

Hi!, no gasket in the sprocket shaft cover? My RGV uses one.

[@JustFixIt99]

Hmm, I don't believe my gasket set came with one. I'll have to double check a parts fiche though to make sure it ever had one. I can't see why it would though. It doesn't seal anything in or out...
