Hi Burty,

Have emailed them.

Thanks

if you dont have oil the engine will just 'age' extremely quickly, to the point it fails.

Dude get real!!!

Engines with no lubrication seize. They seize because the lack of lubrication causes high levels of friction which (rather than just wearing the engine out quickly as you say) generate massive amounts of heat. This heat then expands/melts the soft aluminium pistons and causes them to stick in the bores. Burns up the bearing surfaces too.

Does the stock oiling system mix the oil & fuel 'pre carb', or does it inject it separately from the fuel?

JamesM · 12-03-2007, 05:22 PM

I don't know I've never had an oiler. I think its pre carb though but I stand to be corrected.

On my v old motor it was mixed pre carb & pre mechanical pump.

Jon Fuller · 12-03-2007, 06:00 PM

I see, no jetting changes needed then.

Hi,

From what I can decipher from the layout. The oil pump adds the oil mix to the fuel pipe, before the carb. Not sure if this helps. See pic.

This is what you need dude.....

You put your petrol in....
Your 2 stroke in....
Fuel in, oil in, you shake it all about.... etc.

Seriously though - I've always premixed fuel and oil on race bike engines that have been derived from road motors. I've never trusted the standard oil injection not to fail. It's a new engine if it does. Eek!

Peterjfinch · 12-03-2007, 07:34 PM

How the hell am I going to get 200 ltrs of fuel and the 2 stroke oil, down that little hole?

ahh yes! never though about it like that!

cheers for the explanation dude

I don't think so

The bet is Ross hits Puberty before his boat hits 94mph in the chop

Tw*t

Hi All,

No replies from email either. Found this picture of the system.

Oil Injection Components
Numbers refer to key numbers in drawing below.

REMOTE OIL TANK--Holds three gallons of oil. The tank is pressurized thus forcing oil up the outlet hose to the oil reservoir on the engine.
OIL PICK UP TUBE--A filter screen is located in end of tube to prevent dirt or other particles from entering the system.
OIL RESERVOIR--The oil reservoir feeds the oil pump and contains enough oil for at least 30 minutes of full throttle running after the remote tank is empty. The warning horn will sound if the oil level in the oil reservoir is low.
OIL INJECTION PUMP--Injection pump is driven off the crankshaft. See illustration on Page 4 (follows). The oil injection pump is a variable metering pump. At idle the pump will meter the oil at approximately 100 to 1 gasoline to oil ratio and at WOT, 50 to 1 ratio.
2-PSI CHECK VALVE--If oil flow to reservoir is obstructed and injection pump continues to pump oil, the 2-PSI valve will open to allow air to enter reservoir to prevent a vacuum.
2-PSI CHECK VALVE--This valve prevents gasoline from being forced into the oil lines.
VENT HOSE--Hose is only used to keep check valve clean. Other end of hose is not connected.
LOW OIL (FLOAT) SENSOR--If oil level drops in oil reservoir, the sensor will signal the warning module to sound the warning horn.
MOTION SENSOR--Senses the rotation of the oil injection pump drive system. If the drive system for the injection pump becomes inoperative, the sensor will signal the warning module to sound the warning horn.
WARNING HORN
Sounds the warning horn briedly when key switch is turned on, to indicate that the system is operational.
While engine is running, the module continuously monitors the rotation of the drive system for the oil injection pump picking up pulses from the motion sensor. If drive system becomes inoperative, the module will sound the warning.
If oil level drops in the engine oil reservoir, the low oil (float) sensor will signal the module to sound the warning horn.
