Topic: Leaky pulse generator cover- Nighthawk 750

[DustyRags]

Hey folks,

I've slipped to the dark side, and I'm running a DOHC these days- 2000 Nighthawk 750 (last of the CB750s).

Unfortunately, I've also slipped on some ice, and scraped up the pulse generator cover (left side engine case cover, what you'd call the points on a SOHC) at about 15 mph. It started leaking a bit, so I popped it off, replaced the gasket, and torqued all 4 bolts to the requisite 7.5 ft/lbs.

It's still leaking

Anybody know anything about these guys? Does it require/is it safe to use gaskaseal or something? There's effectively no info in the manual.

Any help is appreciated! The slip also busted my kick stand cutout switch (which I, erm, cut out and taped up), and finally blew a fork seal (fixed that mid-trip in Portland). The leak is following me, though.

My nighthawk is about 18 years newer, so cannot comment too much.  But the pulse generator should be dry and not leaking anything.  you have a leaking crank seal it sounds like?  The gasket is meant for keeping dust and water out unless is somethign different done there...

18 years newer? a 2018?

The only documentation I could find on that was from a guy who was trying to check his timing, and found it full of oil. Guess his could have gone out too...

EDIT: Nope, at least one entry on another forum says that's normal- the pulse generator has oil splashing about in it. OK, will figure out later, it's 2:40 am right now, time to crash. Thanks for the response, I'll keep poking at it as time permits!
