My final drive output seal (78 R100RS) started leaking last fall and spitting oil onto the rear wheel. That was my first trip into that thing! I did ...

My understanding is that our Bing CV carbs are actually quite good at compensating for changes in elevation without modification. Both the carb nee...

Curious if you found the cause of your hiccup and idle speed drop. Did the timing light reveal anything? It’s an interesting issue you were having.

@mark-creek I’m kinda half kidding. Even in a stiff breeze I wouldn’t let it run more than 10 minutes. I can also tell when the engine is getting too ...

@wobbly PS: oil pan gasket(s) - use no sealant or gasket dressing? Or, what do you recommend? Snowbum says no sealant. EME told me their gaskets req...
