My Virago XV535 was in winter storage and now the front cylinder only fires up on a higher rev than idle. With choke on, it contunues to run, but without it stalls. Back cylinder operates normal. Both sparkplugs are fine (replaced them and spark is OK) Carburator issue ?

hi!! there is a bad vacuum leak. take to your dealer for repair!!

To me it sounds like the coil is breaking down and not working at higher RPM's. You can take them off and have them tested at a service shop.

Yes, the problem is likely the "low/idle fuel circuit". There's choke, idle, and hi rpm fuel "circuits" (not as in electrical). The idle clogs first since its small, and the front cylindar seems to go first on this bike. rebuild w/gaskets. 3 hours shop labor = ~ $240. good luck.

My 'wing won't run unless it has been warmed up some. I would suggest that you r&r your carbs to make sure the jets in the bottom are working correctly. They tend to get plugged up, especially after sitting & the aluminum flaking off inside... Rick

****, squeeze, bang, blow... check filter, fuel and spark... its going to be prob a fuel problem. if the bike hasnt been running all winter run some gumout through it... and get rid of the fuel thats been sitting in the tank. more info would help but it sounds like you got varnish in your carb....
