Synchronizing throttle body trouble

[Slopeflyer]

Built homemade manometer. Warm engine,set idle at 1350,shut off, install tubes. When I start back up it sucks all oil out of #4 tube within a second or so. Tried closing it down(clockwise) no help,open it up a couple turns no help, did everything in between. I can't run the bike long enough to do any adjustments.
Started it so many times last night the battery went dead. Recharged battery overnight any ready to try again.
So frustrated ready to take up :smoking:

You need some restrictors as theres too much strength. Find a way to insert something in the hose to cut the size internally by 75%.

I use the cheap plastic aquarium valves from the pet store/ wally world. Pack a little grease around the threads to keep from sucking air. Now you can shut them all off, crank the engine, and slowly crack them open, tweaking the adjustment screw until you can get the manometer levels close enough to open the valves further.

I have 1/8 connectors stuffed into ends of 3/16 connectors. It did help so the flow but not by much.

I didn't help slow the flow. Have to look for the shut off valves. Thanks for the heads up.

The restirctors on my Morgan Carbtune are EXTREMLY SMALL.

Just measured them, .025", yes 25 thousands of an inch (ID).

Checked with a WIRE spark plug gauge for checking iridium spark plugs..
