Re: Previous owner running 25/1 mixture in tank. 2stroke...
It doesn't inject oil into the crankcase on a 2 stroke. It is mixed with the petrol at the carb. But, it is difficult to tell you how to check it as you haven't said the make and model of your bike!?!?!
1982 TF 185 Suzuki. i may stand corrected but the two hoses going to the crankcase 1 to the rear the other to lhs near the barrel is I thought they were oil pipes to lubricate the crankshaft bearings1982 TF 185 Suzuki. i may stand corrected but the two hoses going to the crankcase 1 to the rear the other to lhs near the barrel is I thought they were oil pipes to lubricate the crankshaft bearings

You may have overfilled your oil tank. Always check your oil level with the engine at full operating temperature. Avoid the temptation to "top it off" when you check it cold. As long as you can see the oil on the dipstick, start the engine and run it until it's warm. Then only add oil if it's below the lower line. Check the oil level of your Fat Boy with the bike on the side stand. Your Harley has a "dry sump" type oiling system on it as it pumps oil into the engine that lubricates things and then pumps it back out into the oil tank. It does not carry the oil in the crankcase like other machines. It will run fine with as little as one quart in the tank but this may not give the oil sufficient time to cool and I don't advise that. On the other hand, don't overfill the tank as you leave too little air space in the tank for the crankcase to vent the pressure. The only other thing I can think of is to smell the oil and see if there's gasoline in it. If so, you may have a leaking carburetor diluting your oil with gasoline.
The R5 had Autolube....which is automatic oil injection....no gas/oil mixing....there was an oil pump in the crankcase, with one cable from throttle running to the pump so pump stroke varied with throttle opening.....the oil tank for the injection oil was under the seat on the right side.
"Spewing out of the intake manifold". Check you oil tank. If the level is really low, it sounds like the scavenge side of your oil pump is not working. If the oil is coming out of the intake that bad, the engine is full of oil.
The Harley oil system is a "dry sump" type of system in that the oil is not carried in the crankcase like in the Japanese bikes but rather in an external oil tank. The oil pump has two sections in it. A "feed" section to pump oil into the engine and a "scavenger" section to pump oil out of the engine and back to the oil tank. If the scavenge section is not working, the pump will pump all the oil into the crankcase but it cannot pump it back out. When this happens, the oil is blown out of the crankcase vent system and into the intake manifold.
Those models had an oil tank and oil injection system to inject oil into the crankcase. We recommend plugging off the original oil injection system in favor of mixing the oil with the fuel on these older models unless you are sure that the stock system is working properly.
Like most 2 stroke weedwackers they run on a 25:1 fuel ratio.
It is advised that you mix the petrol & oil in a separate container (remember to shake it for a few seconds) first to ensure it mixes properly.
Example:
1 Liter of petrol needs 25ml of oil. (Use 2 stroke oil)
Hope this helps.
2-stroke gasoline engines don't use a reserve of oil in the crankcase the way 4-stroke engines do. Instead, you add oil to the gasoline to ensure lubrication of the engine. The correct ratio to mix would be in the owner's manual.
Two strokes are bad with fuel/oil mixure. If this is premix theres a problem,if injected you may not be getting oil injected. Topends will heat up fast without oil. Fouled plugs and the wrong gap will also cause these problems. Check carb boot for cracks as air leaks will also starvel fuel out. Spray WD40 into carb throat with out tank hooked up, if it fires up, clean carb and reset float. Make sure the spark gap is correct. Check to be sure you have not slipped a keyway on flywheel which would throw timing off and it will only start by accident once every so often.
Wow!!If you live in alaska is diff. to florida.The usual in warm weather is;Choke/half on,1/4 throttle.2 pulls..Should start.Make sure before you do all this,the fuel bulb is totally primed.The motor is born to run at 50/1 fuel mix.If you changed the carby mixture,dont run the motor untill its set back to standard.It may do some damage.The oil is there to lube the pistons etc.the carb mixtures dont often need to be touched.Before you do spend dollars,try a different fuel lead that does prime up the fuel.Be it a friends or the local shop.They should help.Hope this may help
Hi Dan, Why do you want to disconnect the vital oil supply? If you are experiencing too much blue smoke or plugs oiling you can adjust the amount of oil fed to the engine via the secondary oil pump cable,the one that splits off from the throttle to the carb. If you disconnect the cable it also stops the oil pump sending oil to inlet, winding out adjuster increases oil screwing in reduces. As for ratio? trial and error as No knowledge/specification is available for Oil injected engines, poss 25:1 to start but don't blame me if you seize? Quality synthetic oil is always a must, did you know you can also purchase smokeless two stroke oil? Good Luck! Paul 'W' Please remember the Fixya button if my efforts are respected?
