MC28 Oil Pump Alignment Marks/Quick Turn Throttle

Sun Sep 04, 2011 6:31 am » Post: #1 » Download Post

As I've figured out I have a quick turn throttle on the bike, I was curious if this had any impact on the oil pump. There wasn't much info on the matter when I searched (or I was using the wrong search words), but some seemed to think it was OK and others said not OK.

I've experimented and have concluded that running a quick turn shouldn't matter, since the oil pump cable is connected to the carb end (buttery valve for a lack of another name to call it). The throttle cable still moves the same distance as a stock setup would.

Anywho, I've adjusted the oil pump cable so that with 1/2 throttle, the first alignment mark lines up. But should the second mark line up at WFO (wide F-in open)? I plan on going really fast (lmao) and want to make sure I don't grenade it the first time out. Is it better to give it more oil than less for going fast in higher rpms?

Thanks!

Dana

Should help. The beauty of running the oil pump is when you snap the throttle shut from a wide open run, (about 300m to early if your me!) it's still pumping oil even at closed thottle.

Good find.

So full throttle is the adjustment I go with then. I wonder if I'll have to adjust it to the point it's open even at idle...?

Thanks pvan!

It won't change a thing, the oil pump position is taken from the carbs, not the throttle directly.

You have to watch those buttery valves though! Smile

Have you actually watched an oil pump pump oil in the closed thottle position?

And you still get e small supply of oil when you "snap the throttle shut" on premix as even if the throttle is shut the butterflys never are (if they were the bike wouldn't tick over and would stall if you closed the throttle and dipped the clutch).

True, true. Very Happy
Run my road bike with the oil pump, the track bike is on premix. Neither has given me any problems.
