so my 2004 kfx 400 was running bad, spittin and sputterin. the spark plug cap corroded and lost connection. Quad sat for a month in the garage, then i got the cap and wire to get connection but still wouldnt start. then I checked the oil and it was way too full. then took out the bolt on bottom of engine in case to drain the oil there and nothing came out. changed oil and oil filter and still wouldn't cycle to the engine from the resevoir. the oil would go all the way through the filter because i could cycle it with the filter out and watch the oil pump. then i pulled everything off quad, was going to take the engine out but dont know how to get the oil lines off. wondering where it could be clogged? was told by a friend that my orpheus is clogged but I dont know where that is. Also could it be the debris screem? if so how do I get to that? And any advice on taking off the oil lines?
