I just bought a Bayou 220 "for parts or repair." It's in rough condition, but everything seems to be there. The guy said the brakes are frozen, battery dead, tires are bad, and it probably needs a carb. Has been sitting for many years. When pulling the cord, the compression felt strong, and it rolled easily after some air in the tires. For $200, that seemed good enough. I paid him and put it on the trailer.
Back home, I noticed that the key switch was broken, the coil was hanging against the exhaust and melted, and the spark plug wire was all taped up, so I bought a key switch, coil and wire, all for $25. Knockoff parts for this machine are certainly cheap enough.
I have virtually NO experience with ATV engines, but I know the basics.
1. I pulled the cord while holding the spark plug boot away from the plug. ZAP! Got me! She definitely has spark.
2. The headlights came on while I pulled, so the charging system seems to be working.
3. I plugged in a compression gauge, pulled the cord and got her up to 125 PSI. (Is that okay?)
This all seems pretty good to me. I think it's worth replacing the battery, but where should I go from here?
What would you do next?
