I have a 1996 polaris sport 400L 2 stroke automatic and 45 minutes after my fiance bought it for me. Paid $1,300 for it. But anyway 45 minutes and it just shut down on me. Almost as if i turned the key off and just shut down. I got all new gas. new plug. New flushed and new coolant. New battery. My circuit breaker next to my battery was blown. I replaced it with a inline fuse. I cleaned my stator it looks good from what i can see. I checked all of my electrical for continuity and all passed. I get. Spark. I get gas to carb. And i only get a little rumble of it getting any fire about once about every 20 or 30 yanks on my pull start. Starter was not on the bike when we bought it. Driving me nuts of why bike does not start. I also bypassed oil mixer.
