Honda 300ex slight oil leak and tick

Recommended Posts

So I just traded my bike for this honda 300ex runs good other then the slight tick and oil leak coming out of the brass looking bolt on the top right above the plug boot (not sure what its for or called so not sure what I need to order) and as far as the tick i think I need a new cam chain or tensioner because when I let off at high rpms you can hear it rattling on the right side of the motor thanks for the help In advance

Any ideas

Are you talking about the slotted flat head? Those are the rocker arm shafts. There is an o-ring behind the head of that shaft. Needs to be replaced. The ticking is probably the rockers, being lose on the valves. Needs adjusting. Get yourself a service manual. Both of these issues are very easy to fix. Good luck.

That's it.  (Part # 91303-428-003) Size (7.7X2.5) Order with Rocky Mtn. get it in 2 days. Or if you have a local bearing and seal warehouse, they may have them. Good luck.

Not quite that easy. You'll need to remove the valve cover. Then remove the rocker shaft.
