That was a great post. So 32:1 is richer than 40:1. I'd rather run it richer at 32:1 to make my plugs last longer. I don't race at all, I just use this bike for trail riding. As for the optional plugs in the manual for hotter or colder temps, that's mainly for extreme weather conditions right? Also, I've heard that the newer kx250s, like my 2006 are meant to be run lean as in 40:1. In either case, I'd rather just run mine rich at 32:1. So at 32:1 on a 5 gallon tank it's 20 ounces of oil right?
Each gallon is 128 ounces. So 5 gallons X 128 ounces =640 ounces
640 ounces divided by 32 is 20 ounces. Did I figure this correctly?
One more thing, how do I remove the cap off the top of the spark plug? Cause I unscrew and screw the plug in and out with it on and it's a pain in the ass with the cap on it. I tried pulling off from the plug but it won't budge. I wish the mini manual(manual that came with the bike, not a full service manual) was more specific on how to remove the spark plug cap.
Also, I got my airscrew about 1 1/2 turns out and tom I'm going to get a BR8ECMVX plug, which is stated as the standard plug for my bike. How do I tell if this plug is resistant? I'm also wondering why my plug fouled, especially since it's brand new. Should I make the air screw richer or leaner by 1/4 turn? When it's richer, does that mean there's more air/fuel or more fuel/air?
Also, if my bike falls to its side, will the carb flood? Cause one time it fell to the right and it seemed like the carb flooded cause it wouldn't start. I drained the carb and then it worked. Does it matter at all which side it falls? Like if it falls to the left, will it still flood? Also, I have a 2004 kx250f and it never floods the carb whenever I lay it down on its side.
