I was wondering if any one had any idea on what may be going on with my 2005 suzuki gs500f that i picked up last week, first thing i did was get it looked over by a bike shop, new tyres, brakes, everything checked kind of thing. I went for a ride today, seeing as though it was the only decent day to do so this week, everything was fine until about an hour and a half into the ride, when i felt the thottle stop reacting, so i'd pull it, nothing at first, then it would come on, then drop off, even with the throttle pulled, as i decelerated, changing down gears, could not get engine to rev up, with the final time pulling the clutch in to change down, engine shut off completely. this happened another 4 times on the final 5 km journey home. I would have to stop, turn the ignition off, and start again with the choke, which was really wierd. with the advice that it could be the side stand switch malfunctioning, i took it for another ride to see, and when i'd give the stand a nudge, it would try and stall, but then as the stand came back up it would be fine, not loose all power like it did the previous times. It wasn't till i gave it some beans and then backed off did i notice it did it again, this time i just held it at half throttle to see if it would kick back in, but nothing, it just went down and down, till the engine cut out again. once again, having to switch it all off, restart with the choke, and get it home. really freaking out, any ideas at all what i may be looking at????
