2000 AC ZL 500 with baterryless EFI. i rode it for acouple hours yesterday without a problem. got it running today but it wont stay running . it runs for about 30 seconds or so , then it quits. it revs up to about 4500 rpms all on its own ,then stalls out .its runs when i pull it over again but does the same thing every time. it will bogg out when i give it throttle and quit again. itwas almost below zero last night, i thought that it might be the watered down gas that we have to buy now, frozen in the fuel injection system . but if that was the case why doesit even run to begin with? i put some dry gas in it any way. same problem. changed out the plugs no change and definetly getting fuel. im getting frustrated with it . anyone have the same problem? if so what corrected it ? any suggestions?
