Hope everyone is having a great weekend,
While riding my quad just quit, I mean dead. No life on the dash, no crank and obesity no start.
Had a quick look under the plastic, batt reading 12.7v power at the key switch.
Changed the power pack, still no luck.
Anyone else have similar problems?
I don't see a fuse box/panel, is there fusible links in the system? If so where di I start looking?

So this is what happens when a atv sits for many many years.. TIme for a good cleaning. At least the tank looks pretty clean inside and petcock is working now after a good flush.

Hey freinds, I picked up a beautimus 02 kaw 220 bayou. What I know about this machine .. Not ran in 4 to 5 yrs after providing seller with yrs of trouble free service . It was left under a tree after the seller bought a larger atv.
After sitting for 5 yrs My 1st gift was
1)fresh oil and filter
2)new gas and "filters" 2 inline
I'll explain in a sec.
3) new amazon carb airfilter and boot to carb
4) Start and ran for 30mins
5) add a little atf fluid rans 3 mins
6) another new oil filter and more new oil
I FORGOT NEW battery also....
I pulled it twice ..not doing that agian
The bike ran like a top no worries besides thee reverse cable will not function as its ment to.
After 3 to 4 weeks it started to die.
I found white crude in the carb from water In the fuel somehow.. not sure how..
So new amazon carb as I boughtv2 the 1st time in case one was crap.
I've bought alot of these cheap carbs only 4 or 5 percent has been problematic ..
So back to a clean tank and added 2 inline filters just incase and it starts runs idles like a new bike . But thus time I have a small stumble in the 1st 10 to 15 percent of throttle travel.
We are in Texas about 130 ft Elevation. Reckon the jets need adjustment or replaced or is there other adjustments I can make.
Cheers joe

Have a carb off an '07 Big Bear 400 that sat a couple of years, probably more. Friend asked me to clean it, which I did, soaking the jets and spraying out all of the ports with carb cleaner as best I could. Replaced o-rings, needle valve & seat, tweeked float level. Bike starts and idles well but doesn't want to pick up above 1/4 throttle. That would appear to be in the slide needle range. Main jet is clean, needle is clean and straight, diaphragm good. It seems I saw (in a diagram) a port that comes into the slide needle area from the side. This would be in the carb body between the main jet and the throat of the carb. I would like to soak the carb in Gunk Carb Cleaner, the gallon paint can with a little basket. Curious what Mikuni uses for bearings and seals in the throttle shaft. I'm guessing HDPE or Delrin, or maybe brass; not sure what effect Gunk would have on the polymers. Has anyone actually soaked a carb in Gunk?? First hand knowledge, please, and what effect, if any, on the carb. Pulling the throttle shaft out would be a last resort. Getting the butterfly screws out and staked back in would seem to be a nightmare.
Thanks
Jim
