Honda Ns400 or 250 owners?
« on: November 05, 2022, 03:04:49 PM »
Are there any Honda NS400R owners that can tell me how to adjust the oil pump?

Been 15 years since I had my little NS400R rocket.
IIRC, The oil pump cable picks-up from a cable quadrant on the main carburettor quadrant. The cable runs down to the pump under the engine underneath a plastic cover. I don't recall the exact setting but, it was the usual marks to align with the normal sort of cable adjustment.
Have fun, loved mine!

I have the 250, basically a 400 minus one cylinder. Great little bike. I had a leaking water pump, so while I have it apart I thought I would check the oil pump, but can't see any marks. Mind you it is bloody difficult trying to crane your neck even with it up on the ramp.

Thank you. My NS250R is a MC11, so not covered in that post, but by scrolling through the forum I found out how to adjust the pump, so thanks once again.
