I just got a dirt bike and i don't know the gas oil mixture for it?

THIS IS VERY EASY TO FIGURE OUT..THIS IS A RATIO OF 2 STROKE OIL TO GASOLINE MIXTURE..FOR ALL TWO STROKE ENGINES ONLY..MOST TWO STROKE OIL CONTAINERS HAVE THE CONVERSION CHART ON THEM FOR THE PROPER MIXTURE..ALWAYS SPEND THE MONEY AND BUY A GOOD BRAND OIL ..ALWAYS PREMIX YOUR GAS IN A SEPARATE GAS CONTAINER SO YOU CAN MIX IT UP VERY WELL BEFORE USING IT IN YOUR EQUIPMENT..NEVER STORE YOUR GAS TOOLS WITH FUEL IN THE GAS TANK..ITS BEST TO RUN EMPTY BEFORE STORAGE..THIS WILL PREVENT THE FUEL FROM GUMMING UP YOUR CARB AND SUCH..SAVES MANY HEADACHES..PLUS SAFER..

32 TO 1 SHOULD BE SAFE..BETTER TO BE A RICH MIXTURE THAN A LEAN ONE..ALL DEALERS WILL HAVE THIS INFO FOR THERE SPECIFIC PRODUCTS..MAKE SURE YOU GET THE CORRECT MIXTURE FOR YOUR ENGINE ,,BECAUSE YOU COULD END UP WITH ENGINE FAILURE..AND USE ONLY APPROVED OILS BY THE DEALER OR BETTER..ROYAL PURPLE FOR,,EXAMPLE..

32:1, 4 oz. oil per gallon of gas

Are you sure this is a DT 125 as with this particular bike it is self mixing there should be a separate tank by the handle bars just under the front plastics opposite the water tank this is where you fill it with oil then just put gas in the gas tank and it will mix it self you do not have to do anything else do not put oil in the gas tank with the gas mixing would usally be dirt bikes or really old bikes only

Use 50:1 ratio or 2% oil in the mixture.
That means 20ml oil for every 1000ml (1lit) of gas.

hello sir, the gas / oil ratio is, 3/4 o/z per quart or 2.6 o/z per gallon of two cycle oil, any two cycle oil will do,this is how i mix mine and never had a problem,it is a good mix.hope this helps,don't forget the 4 thumbs up,any comments welcome,thank you. ~~

Oil change intervals for motorcycles depend a great deal on your riding conditions and riding style. For lower-revving street bikes, I often change my oil about every 2000 miles (~3200 km). However, someone with a sport bike who regularly revs their engine closer to the redline, I would suggest a more frequent change interval. Off-road / dirt bikes should have their oil changed sooner because of the dusty conditions. The oil is still full of lubricants, but it is contaminated with dust and dirt that clogs the filter and eventually goes right into the engine, increasing wear. I can't offer much guidance for dirt bike oil change intervals.

the mixture ratio is 50 parts gas to 1 part oil. Use only a good quailty stroke oil, never use motor oil

first off make sure the oil gas mixture is correct and mixed very well.... have the carb cleaned out very well or even rebuilt, jetted and adjusted...

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.
