Hello all,
I am new here and am hoping for some help with a sled that I have. It is a 1997 V-Max 600 XTC. It is running real rough from idle to about mid throttle. It does not matter how fast I take off, it always runs bad until about midway. On top end it runs great. It seems to be running real rich in this range. The plugs come out black with an oily wet residue on them. I have searched a lot on this topic and found some info saying the oil pumps fail a lot, so I bypassed the pump and used mix and still had the same results. I have cleaned the carbs twice (completely disassembled and sprayed / blew out). I checked the float bowl level with it running and it seemed to be in spec. When I reassembled the carbs I set the air screws at 1 1/2 turns out. Should I take them in some?? The jets are stock. Any suggestions / similar problems? Good sledding snow does not last long in Indiana so I need to get it running good fast!
Thanks!!
