SOURCE: problems disconnecting oil pump so i can premix the gas instead!

from what i can remember(ihad one years ago)the ke uses disc valve,as apposed to reed valve.but the anwser is quite simple.if you dont want to remove the pump,just block the lines up with a couple of little bolts,and jubilee clip them in place to stop the engine drawing air in and weakining the mixture.

SOURCE: do i have to mix 2 stroke oil on the gas for the 4

DO NOT mix oil in the gas on your four stroke engine. You will foul the spark plug(s), build up deposits on the valves and head, and make a smokey, smelly mess. A two stroke engine uses the fuel/oil mix to lubricate the engine before being used as fuel. A four stroke engine has a separate lubrication system and does not normally burn any oil. As the name implies, a two stroke engine works in two strokes. The first stroke is downward, where the fuel/oil mix and air are drawn into the cylinder. The momentum from the crankshaft counterbalance or force from the other cylinder(s) drive the piston back up compressing the mix, and the spark plug sparks at or slightly before the top of the stroke. The rapid combustion of the fuel/oil/air mix drives the piston down, which is the power stroke, and then the cycle starts all over again. A four stroke engine has an intake stroke down taking in the fuel/air mix, a compression stroke up, a power stroke down as the fuel/air mix is ignited at or before the top of the stroke, and a exhaust stroke up before starting all over again. A four stroke is much cleaner and more reliable than a two stroke, but it is heavier and has less torque. A two stroke engine is much lighter and has more torque, but takes more maintenance.

SOURCE: what oil should i have in yz 125 2 stroke

The clutch and gearbox share the same oil. The oil for the motor is 10w40. Stick with the major brands; Pennzoil, Quaker State, Mobil, Yamalube or Shell.

Change oil

It is a 2 stroke there isn't any oil in your engine perse, basically your bike either runs premix fuel or it has a oil reservoir that injects oil in to the fuel mix. 2 strokes mix fuel and oil together in the crankcase, that is why 2 strokes are somewhat smokey. The oil that is injected or in the case of premix is what is used to lubricate the engines internals. So you won't be able to change the oil by draining it out of the engine block. If it has an oil reservoir you will need to top that up from time to time.

Hello i have a 1976 kawasaki ke 125. i don't know how to fuel the bike and i already put a new top end on it. how do i fuel it, do i put oil and gas at the same time, or gas in the tank and oil in another...

take off any side covers to look for a small oil tank. This bike should have a pump that meters this oil into the gas. Put your 2-stroke oil in there.

My 1992 kx 125 gets hot and ceases the rings to the piston why we put ani freeze in it

This is a common problem that happens with all 2 strokes, maybe the oil pump is not set up to the throttle or is malfunctioning

What kind of oil do i need to mix in a 2002 yz 125?

You have a 2 stroke dirt bike, off road only, without oil injection. Get a gallon of 2 stroke oil, get the mix from the owners manual or the dealer, should be about 1 pint per tank? Or 4 oz per gallon. It might be more. Don't try to get away with burning motor oil in there, it won't work, it will overheat the engine and could do some damage. Hope this helps.

2003 Yamaha 125 yz plug fouls pretty quickly. running 32/1 fuel oil ratio, and using NKG plug 2411/B8ES. Do we need to run a hotter plug?

NGK BR9EG is the stock plug for your bike. You are one heat range hotter already. I suggest you go to a BR8EG to keep you in the racing plug style but one range hotter than stock. I question what 2 stroke engine oil you are using. Stick with Yamalube 2 stroke oil and you should be okay. If you are using standard motor oil like you have in the gearbox then the fouling is definitely the oil.

First bike do i mix the oil and fuel on a 06 cr

If this is a Two Stroke Motor and it does not have Oil injection..

Then Yes and if your not sure it's safest to mix rather than not..

the worst you could do in the following situations is:

- if you have a 4 stroke
foul a plug and make smokey exhaust

- if you already have oil injection and your bike is 2 stroke, youll foul a plug and make smokey exhaust.

if were to run without any oil in a 2 stroke or too little....

you will sieze the piston rings or the lower crank bearing.... Very expensive to fix...

You actually sometimes have a second of notice from the motor that its about to blow .

when runnin too lean on oil ( too little )
the mototr all of a suddon picks up power on it own, just before it siezes:
this is becaus ethe lower crank bearing a are red hot and the gasoline is vaporizing as it passeacoss them on it way up through the ports,, this make the fuel super volitile..

Hi there i have a yamaha dtr 125 thats smokes

Assuming you are using two stroke engine oil, the pump is pumping too much into the gas. DO NOT use motor oil in the gas. If 2 stroke oil is being used, then get a new pump, fix the one you have or disconnect the pump and mix the oil with gas when you fill up. Four ounces of 2 stroke oil per gallon of gas equals the standard 32/1 fuel mix.

Help with my aprilia AF1 125?

Congratulations. You have just purchased a very high performance 2 stroke 125cc from a very talented Italian manufacturer. A two stroke engine needs 2T oil to be mixed with the fuel before it is fed into the engine. This is a cumbersome job and one has to get the ratio just right. So in order to make the job easier you have two tanks. 1) The regular fuel tank & 2) A small capacity 2T oil tank (made of plastic mostly) which is hidden behind a side panel. In order to give a regular dose of 2T oil there is a tiny oil pump attached to the side of the engine. This oil pump has to be actuated simultaneously when the carb slide is actuated. Hence the banjo. So now you know why the throttle cable splits into 2. One goes to the carburator and other to the oil pump. Good luck and enjoy your bike sensibly.,,,
