G'day, I'm new to the forum having just received my learners. Ive recently purchased a nice little '07 VTR250 from a second hand dealer in Melbourne, with only 5000km on the clock. However yesterday when it finally got delivered to my house, it had quite a bit of trouble starting. I tried both with choke on and choke off, made sure there was fuel, and when i eventually did get it running, it would not tick over without me holding on a bit of throttle. As soon as i let the throttle out, even after the engine was warm, the revs dropped below 1000 and it just stalled. This morning i read up about the idle adjustment screw and was going to try twisting that a bit after i got it started again, but it failed to start altogether!! Eventually i tried so many times that the battery drained, and even jump starting it didnt work. Any ideas what the problem may be?? I'm no mechanic, and only new to bikes, but i do have a solid understanding of how bikes work. Maybe something wrong with the spark plugs? Any advice would be much appreciated. Cheers.
