rats

hi yes i had the same problem, tho i have a sachs 125 v roadster, the same engine as the virago.. i fitted a k n filter too, it didnt like it one bit at first, running lean, then to rich. throttle lag in the low rev range. it was doing my head in big time lol.. i found that it was the filter and had it ram it with rags to restrict the air, it worked put face it its a bodge job so i swaped it for a different k n filter. unlike the common filters that suck air in 360 degrees around the filter, you can get filters for pitbikes that are incased in a cover, the cover has holes in it to allow air through but not to much. try that it worked for me. you can buy them from £15-40... try this link...http://www.petrolscooter.co.uk/air-filter-kandn-38mm-with-blue-cover-pit-bike.html.. hope it works for you goodluck

hi i have a sachs 125 v-twin, that uses the virago engine.. yes ive had problems too, some one nicked my bike and i found it down the road. i think they dropped it, it smashed my carb, and left a crack in it.. after much running around for a carb, i found out that they stopped making that carb 12-13 years ago. seeing as the carb is a side draft, finding one that fits the gap between the intake maniflod and the stock air box was impossible, unless you fit theses new C.V carbs, but it needs a fuel pump and the bike dont have the electronics to connect a fuel pump.. i had got a suzuki gs carb, and a swiviel manifold, and bypassed the air box, with a k n filter.. yes it was very lean at first, then it was too rich, only to find out its running rich and lean due to the k n filter sucking in to much air.. i had to stuff the filter with rags to restrict the amount of air to the carb.. now i have to say it runs well. normal cruzing speed 50-60 the bike can reach 80-90 but i dont do it often hope this helps others who had air filter probs
