Re: 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..

Find out how many gallons your motorcycle tank holds. Do a little research on the manufacturer and model of your dirt bike. Also find out what ratio between oil and gas is required. Then, do a little math, and find out how much oil to add to each tank. Add the oil. Then add the gas. Adding the gas last will help stir up the oil in the tank.
There is a big range of answers to that question but to give you some idea of the answer 32 parts petrol to 1 part oil - right up to 60 parts petrol to 1 part oil is the range of ratio that most commonly would be used . to give some insight in simple terms the more fuel and less oil mixture you will burn hotter and produce more power but sacrifice wear and tare on the motor
realistically the mix you choose depends on what sort of riding you intend to do - if you are racing and want the hole shot then 50 - 60:1 mix with half pump fuel and half race fuel will get you there but you will be rebuilding the top end fairly regularly
For recreational use only then 40:1 mix with standard pump fuel only would be the most common as it is in the middle of the range giving you good power with high level lubrication so ware and tare kept to minimum.
if you make changes to fuel mix then keep the changes small just alter the mix slightly and record the results because you will also find each bike responds a little differently
when I am setting bikes up for events I usually will go out to test area with 3 or 4 bottles each just with 500 ml of different mixtures in them and give each mix a test just for five or ten minutes then once the best mix chosen the I start fine tuning the carbi fuel air mix etc only takes an hour or so and what the hell it's a lot of fun to do any way!
Yes 40 - 1 mix is a common race mix and if you dont do weekly maintenance and regular rebuilds you would be better at 32-1 33-1 mixes as this is more oil to fuel mix so better lube and lower burn temperature inside the motor.
when changing to higher oil mix make gradual changes to the fuel mix 1 tank at a time and record your ration as your bike will respond to the changes sometimes well sometimes bad but if you do small steps and record the result you will know what mix is best for your area and bike
In short the more oil you can give it and still ride well the better fore engine life (within reason) but you will lose some performance compared to less oil mix like 40 - 1 ratio (race mix)
You need to use a 2 stroke motor oil. Look for oils that say 2 stroke motorcycle oil, injector oil or smokeless. Do not use a standard automotive motor oil, your bike will smoke. It should be pre-mixed with your gasoline. I am relatively sure the ratio is 32:1, but you should check your owners manual to be sure. At this ratio you would use 4 ounces of oil to each gallon of gas. This ratio allows for an all-around use of your bike. If you are not going to use the bike at high speeds for extended periods, you may want to consider a different fuel/gas ratio - 50:1.
The above information is recommended for a Stock motorcycle.
Are you sure your fuel mix is correct? I think the mix for that bike is around 1/24-1/26. That is the gallon of gas to the amount of oil added to the gas. Is that bike oil injected maybe? Putting a new plug in tells it's a fuel problem with the "oily" stuff on the old one. Try looking online if you don't have a manual on it. Just look for the gas mixture ratio. But being a two stroke it could get more complicated like the reeds. These are after the carb on the way to the cylinder head. Start with the fuel mix and make sure the gap on the plug terminal is right. You should be able to find that online somewhere too. MAKE SURE YOU WEAR YOUR HELMET AND BOOTS! lol
IF you are no riding bike on the trak an not clutching it much i would use a mix ov 40-1[120ml-5L] if on trck an making engine work hard then use 32-1. OIL-if you look to the left of the oil inlet benerth the water pump there is a nut undo it and when the oil stops flowing out then thats what u need in so try and judge it.
