Just bought a used 99 Blaster for my son and the 3rd time we went out the oil light came on during a trail ride. The shop sujested that I remove the Autolube system, so I did and I'am running a 32:1 mix. My question is that the bike still has exccessive white smoke coming out the pipe. Anybody have any sujestions.[img]i/expressions/face-icon-small-sad.gif[/img]

 

Is it smoking all the time or just at start up? White smoke means oil is burning, at start up it will smoke because it's burning the old oil off the piston. My Blaster oil light would come on if the oil tank was not full all the time because as you ride the oil flys around and the sensor gives off false readings.

 

It smokes all the time I tell my son to follow my warrior so i don't have to smell the blaster.

 

are you sure you jeted it correctly?

 

No I'am not sure I jetted it correctly. Any sujestions on fine tuning it myself would be appreciated.

 

Jetting the blaster is just like jetting your warrior, except 2 strokes are more sensitive to jet sizes. Being 1 jet size off for a 2 stroke has a bigger effect than on a 4 stroke. They also use larger jets, stock on a blaster is 230 main, needle in the 2nd clip(maybe 3rd, not sure)from the top, and the pilot 1 1/2 turns out.

Just do some plug chops and jet accordingly, its real easy once you get the hang of it. I also doesn't hurt to have a clymer manual for it, those things can be life savers at times.

Good Luck

 

If you go to the NGK spark plug web site they have one of the best "How to read a plug" demos I've seen. I beleive it's www.ngksparkplugs.com. In short warm the quad up and then run the quad up to 4th or 5th gear and hold it at full throttle for about 5 to 8 seconds and then hit the kill switch and pull in the clutch at the same time, but don't let of the throttle until the motor shuts off. Stop the quad and pull the plug, it should be light tan to gray in color. If you are running rich it will be black and oily.

 

Thanks Guy's I'll give your sujestions a try.

 

In addition to the other good info posted here, please note that when you remove the oil injection and mix fuel and oil instead, you must rejet.

The stock jetting was calculated based on fuel only through the jets. When you add oil, the jetting must usually be increased since less fuel will be going through the same jet. Also note that you can actually make the engine richer or leaner by changing the mix ratio. For example, using 40:1 as your base, if you go to 32:1, you will be lean on fuel. If you go to 50:1 you will have more fuel per given unit.

In fact, I will make a oil ratio change if I am riding at a different altitude and I don't want to take the time to rejet.

 

I just noticed something in the original post. The oil light is supposed to come on when the oil tank is low. Your shop had no reason to tell you to remove the pump and pre-mix.
