Ok no ones talking about 10:1 or 15:1, they seem to be running 32:1 to 40:1. and you know were talking about dirtbikes? they don't want to do dyno runs, they just want to know why his bike eats plugs, If you know how jetting/carb works then you can see things in a different light. I'm just...

A correctly jetted carb makes a tremendous difference in the torque, midrange pull, top-end pull, and over-rev of your engine. If you have never jetted your bike correctly, you will...

Is there drool "spooge" running down your silencer at the end of a ride? Does your bike smoke at operating temperature? Do you foul plugs on a regular basis? Is your throttle-response poor and boggy?
If you answered "yes" to any, or all of these, your problem...
Preventing Fouling:
So you’re probably asking yourself, why are my spark plugs fouling? The answer is simple.
Snowmobile manufacturers tend to jet carburetors on the rich side as a safety factor in order to prevent engine damage and warranty claims. In addition, manufacturers have to consider...
Are you fouling plugs? Many people will tell you all sorts of band-aid fixes, from running less oil, to running a hotter plug. Both are incorrect fixes for plug fouling. It's all in the jetting.
The only way to know what jetting changes you will need is by trial-and-error. No one can give you...
Actually, you can get more horsepower out of a two-stroke engine with enough extra oil in the gas, because the oil provides a better ring seal and, therefore, more compression. People think that gas burns more efficiently with less oil, and therefore you get more performance. It almost makes...
My wife had 2007 105, and the thing about 105 is it's a real bike .It's race ready with the same quality of parts as there big bike (adjustments and longevity). The bike has more then enough power to walk all over CRF150R(which is made to race in the 85 class) for the same money. Plus 2-stroke...
You know your right ...to each their own. Put you should say why you feel it was good or bad, Just give a little info. and i do remember you, hows the new bike.
If you do foul plugs, it is more than likely caused by poor jetting, not a bit too much oil. If you get your bike jetted correctly, have a fresh plug and a strong ignition system, you won’t foul plugs.
When the motor is idling, or at lower rpms, that’s when the machine has a greater chance of...
Many dirt bikers are mixing their gas at ratios as high as 75 to l, or even 100 to 1 with the new generation oils, in the belief that their bike will put out the most horsepower at a higher ratio. Riders who foul plugs all the time, are put ting less oil in their gas/oil mix, in the belief that...
