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.
Neighbor dropped off his 2010 Ranger 400 HO. Said it was missing and backfiring. I replaced the plug as it was carboned up (kids use the side x side for chores and it is only idled around yard) Unit ran great, sent back home and it ran great for about 5 hours of run time and then it wouldn't start. He brought it back and I changed the plug again and it would start but would not run great. Pull plug and it was really wet. I suspect the carb needs cleaning and that is the direction I plan on going unless someone else knows anything about these units. ( I have never worked on one of these).
If you know of something else I should check let me know.
Also I am looking for a service manual for this unit.
I have a 2001 suzuki quadmaster 500 4x4 that has a rev limiter when it is in any gear other than neutral, i have already fixed a bunch of stuff on it and would love to just bypass it if anyone knows how. Thanks for any help.

1987 YFM350FWTB 350 4x4 Big Bear when going uphill will sometimes act like the clutch realeases then re-engauge all at once.
Seems to maybe be little more often if the engine is at about 1/2 throttle instead of at lower rpms.
I have the Factory Service manual and checked the external clutch adjustment screw as ok and the H/L/reverse shifter lever linkage as adjusted correctly. It appears to be maybe a internal (inside the case) clutch issue or ??
This is the type Big Bear that has the manual shift lever on the left front fender and has the manual foot shifter lever with 5 speeds forward.
Can someone tell me how the primary and secondary clutch operates?
I assume one is mechanical and one is centrifugal. (what I'm asking is one clutch for the higher rpms and one for the lower rpms or ???. (the clutch appears to only momentarily release at the higher rpms is why I ask. The cycle has about 3000 miles of low speed through the brush hunting and has been well maintained, oil changed, etc and no deep water or mud useage.
Anyone been into a similar issue with the big Bear ATV????

I need help with wiring on a 1998 (I think, 10th digit of the VIN was W) Bayou. I'm not getting spark, I'm pretty sure it is due to grounds being off because the harness is pretty hacked as far as the electric start and charging system goes. I'm needing a good wiring schematic. I found one online and there are a few things that don't add up on it so I'm skeptical that it is really for my year and model. Any help would be appreciated. Thanks.
