Well you cant damage it by doing that but if you put too much n and didnt shake it well it will settle at the bottom of the fuel tank and fill the carburettor up with oil as oil is heavier than petrol.why are you not using the oil tank and oil pump fitted to the bike ?best thing to do is put a new spark plug in it turn the fuel tap off roci the bike bacwards and firwards to mix the oil and fuel in the tank,and drain the carburettor by undoing the 14mm nut in the centre of the bottom of the carb,then turn the fuel back on and try and start it up.

Black spark plug means too rich , you will have to replace the spark plug since it has foul up and reset the air mixture screw on the carburator 2 and 1/2 turns outwards.
Check the air filter too.
Hope this helps.

what i would suggest is to ask a mechanic about the effects of unleaded petrol to an old engin .
all i know is that the bike will run as i did it to my old BMW and all i had to do is replace some gaskets .
Best of luck .

SOURCE: When I start up the bike petrol pours out from a

The petrol is coming from the carburettor overflow because it is flooding. This is almost certainly because the float in the carb is stuck down, holding the needle valve that lets the petrol into the carb permanently open. Classic result of the bike being left standing and unused for a while (But by no means the only cause. Dirt in the fuel is also another classic cause of this problem). To fix:

1) Remove the carb from the bike, flip it upside down 2) Unscrew the (usually 4) screws holding the float chamber in place.
3) Clean everything out with clean petrol and, if you have access to one, a high pressure air hose.
4) Reassemble and refit.
5) Pray

Your friend is wrong. All that will do is make the engine smoke a bit until the oil is gone. Remove the tank and put a handful of large bolts and nuts in it. Add 1/4 tank of denatured alcohol then shake the tank all around for a couple of minutes. The nuts and bolts will scrape off any rust very well. Dump the alcohol and the hardware then flush out the tank.

Get a liquid fuel tank liner and follow the directions on the label.

The piston rings are bad. If scarred up, the piston needs to be replaced and the cylinder may need a re-bore.

I have an suzuki ts 185er 02 and what oil and how much oil can I use..and also how much two stroke do I use for every 2 liter petrol ,,and must I use unleaded fuel

TS185 Suzuki which has direct oil injection, and it is a bike and not a saw. Yes you need to run a 87 or higher octane fuel preferably non ethanol fuel. Most of these had direct injection of oil to the fuel, should be stamped somewhere on the crank case.

What kind and how much oil should i put in the crank case of my 1975 suzuki ts 185 and would to thin oil cause it to lose compression?

ts 185 is a two stroke, the crank case oil is actually only the gearbox oil, the volumne is caste onto the side cover(like 750cc).near the filler cap.
The engine oil is mixed with the fuel and is pumped in from the oil tank under the seat.
The wrong oil or no oil in the tank under the seat can cause it to lose compression. and cause engine damage.
Visit a bike shop and get motorcycle gear oil20w50 for gearbox. and two stroke motorcycle engine oil for the oil tank.
As it is quite old someone may have removed the oil tank, thinking they will make it go faster or save weight or another stupid reason, if this is so you need to mix the two stroke oil with the petrol when you fill the tank at approx 25-1 ( 25 litres petrol mixed with 1 litre of oil)

Could you please let me know. 1] Can I use E10 fuel in my new RLT 30 CET 30cc trimmer that I have just purchased and am yet to start up? 2] Is 50 to 1 50mm of oil to one litre of petrol?

Hi and welcome to FixYa, I am Kelly

First off the engine is designed to operate on unleaded fuel. The manufacturer makes no statements at all about E-10 Fuel. I will tell you from experience that you can use E-10 Fuel but.... should you ever have a warranty claim make sure the entire fuel system is 100% unleaded pre-mixed fuel. Your not going to hurt the unit using E-10 fuel as long as you maintain the proper fuel-oil mixtures. If anything a splash more of 2 stroke oil as in 22 mm / liter vs 20 mm. Or (+) 8 mm per gal.

Manufacturers statemenrts and recommended fuel mixtures below:

Thanks for choosing FixYa,

n This product is powered by a 2-stroke engine and

requires pre-mixed petrol and 2-stroke lubricant . Premix

unleaded petrol and 2-stroke engine lubricant in

a clean container approved for petrol.

n This engine is certified to operate on unleaded petrol

intended for automotive use with an octane rating
of 87 ([R + M] / 2) or higher.

1 Litre + 2 0 ml =

2 Litres + 4 0 ml =

3 Litres + 60 ml = 50:1 (2%)

4 Litres + 80 ml =
5 Litres + 100 ml =

Do i mix the casstrole oil with the petrol for the aprilia 125

It depends if you still have a pre mix tank already fitted. Mine came with the pre mix tank taken off. It is a white coloured container in a fairly flat shape on the 98 model which should be underneath the seat when you lift it. Not sure about newer models. It should have 2 stroke oil in (quite often pink). If not I have been advised to mix the 2 stroke with the petrol at about 50:1 ratio, however I would check with your local motorcycle shop or Aprilia dealer. Alternatively get a workshop manual for the correct year of bike and it will give you all the information you need in there. Also if the tank runs to empty it has to be bled otherwise if air is in the pre mix tank it can cause damage to the engine.

Want to no if it takes petrol on its own when fueling or 2 stroke oil added to it aswell

i guess your asking if its a 2 stroke or a 4 stroke right ?
2 stroke engines dont have an oil filler cap , just a fuel filling point, the fuel used in a 2 stroke is just normal unleaded (aus) but you mix 2 stroke oil in the fuel before filling (about 50/1) or whatever it recomends.
4 stroke uses the same fuel but you dont mix the oil with the fuel , it has its own filler point for oil , however you must use a 4 stroke oil with these .
hope this is what you were after.
