Okay guys have an issue here with my rancher. It is a 2008 Rancher 420 footshift 4×4, supposed to be one of the most reliable out there, and it was until yesterday.
I had a friend come over to look at purchasing the atv, he drove it loved it and is supposed to let me know whether or not he takes it.
After he left I drove it back out to the shop and put it up, roughly 5 hours later I went to back it out and the quad did not want to start. I finally got it running and then it ran terrible. Idle was different than normal, it seemed a little higher but nothing crazy. I drove it around the yard and it runs OKAY until about 1/2 throttle at which point it bogs and skips, if you hammer down and get it above that area it goes back to running OKAY again. Now it did have some type of cheap air fuel controller thing on it, my friend touched it yesterday asking what it was but I am 99.99999% sure that he did not adjust it, when it started running bad I played with it a little bit but it has very minimal affect. I took it off last night and the bike ran the same way so I do not think that is the problem. Oh I also changed the spark plug, the old one looked bad but a new one did not help at all. oh and this test ride he took it on was no mud water nothing, it was down my road and back and around my yard.
ANY and all help would be appreciated, i have another rancher I can check stuff off of but I have no idea where to start
Thanks guys
