Good Morning All!,
After a significant amount of reading and tinkering, I'm stumped. We have a pair of Arctic Cat DVX 90s (4-stroke), and one of them runs very rich at wide open throttle. I've cleaned the carb (which was installed new last year), verified the main jet (80) to be per the original spec, installed a new air filter, tried a hotter spark plug (CR6HSA), and adjusted the valves (tightened a modest 0.0005" but improved starting). The hotter spark plug may have help just a bit, but not appreciably.
Just for fun, I swapped the CDI between machines, and that didn't help either.
Fouling plugs very quickly, but not to the point the machine will not run or start. [black instantly]
Logically, I assume I'm revving out, but the other machine doesn't "stumble/blubber" anything like this one.
Should I try a smaller main jet?
Any ideas you guys may have would be much appreciated.
Thanks in advance everyone.
So I was looking at my John Deere today and though, how could I make this cooler. So I tinted the windows. Lol.
As I got home I was staring at my Polaris and the wife’s kfx. I thought I would have to replace the crank because of piston slap on the Polaris. Turns out I just had to adjust the choke cable a tad more. Runs great.
Why do we have insurance if we only need it sometimes, and that’s questionable.

I have a 2002 Suzuki LT-F500F, and am a first time atv owner. I rode two wheel bikes for many years, and now, two months in to being a new at owner, am just not enamored with the thumb throttle, and I’m wondering if anyone has tried a conversion to a typical twist grip throttle as found on all motorcycles? If so, how do you like it?
