well let me start off by saying dont laugh lol basically i was going to fill up and me and my mate got side tracked... so i did not fill up...the bike would not start at all so i got it recovered ( the guy came with his best tools.... easy start and screw driver lol ) got it recovered cleaned all the carb fuel tank pipes etc got it going again but it revs then it seems to drop in power for a few seconds and then kicks in again going to change plug tomorrow but any ideas what it could be ? thanks ( sure im not the only one whos done it lol ) ( hope not )
