Do you know anything about dirt bikes?

Question

if my dirt bike keeps needing new spark plugs.....what could cause this problem? seems like even after i hardley use it the next time it will be sh*tty again. suggestions?

Answer 1

Do you ride your dirtbike fast or hard? If not, then the lack of throttle will foul the plugs. It does not take very long to foul a plug if you do not get on the throttle. I used to think the same question? Now I throttle and there is no running and getting a new spark plug everytime now. Good Luck!

Answer 2

is it a 2 stroke?if it is, your 2t ratio is probably too high making it rich and causing your spark plug to foul...if its not used...it also fouls as all the 2t have probably settled down on the spark plug...get your mechanic to lower the 2t intake...that should be fine :)

Answer 3

Is it a 4 stroke or 2 stroke?

Answer 4

If your dirt bike is a two-stroke (where you need to mix the oil & gas together) it is probably that your mixture is wrong or you are using cheap oil. If it's a four stroke, your carb needs to be adjusted.

Answer 5

If your bike is a 2 stroke, your gas/oil ratio could be off...  you should be between 30:1 to 50:1. Also, make sure you set the gap of your spark plug before you install them... if your gap is shallow, you won't get as strong of a spark...  thus not burning all the oil and fuel in the cylinder..  fouling the plug quicker. Check you bike's book for spark plug gap adjustments and fuel mixture ratios. You can even go as far as putting smaller jets in your carburetor.

If you have a four stroke and are fouling plugs, try a higher octane fuel, 95+ and clean your carburetor...  your floats in the carburetor may be to high, letting excess fuel into the cylinder...   lower then a little and it can help.

Good Luck!
