Hello All, I'm new to this forum but hope to get to know it! So, I was riding my KLX-140L after doing some small jumps, and all of a sudden, I had a loss of power, to the point where the bike could only go 5 mph in any gear. I turned the bike off and started it again, and still had no power, so I pushed it back to my garage ( I was in my backyard/orchard ) I unscrewed my oil cap, and smoke poured out of where the oil should be, ( I had the correct amount of Oil in the bike ) I let it cool down for about an hour and started it again, and I could get to about 7mph, not really any faster. Before the problem, I had had trouble shifting out of neutral, but then I rode for 2 hours and it ran perfectly, jumped perfectly, went fast, etc ( it was riding VERY good ) When I'm in neutral I can rev the engine perfectly, ( so I don't think it's the throttle cable ), when i shift into gear is when the problem starts. Another odd thing is that once I'm moving in first or second gear, I can ride at extremely slow speeds without the bike stalling....... normally at around 5 mph the bike would struggle then stall - but now it doesn't sturggle at all to go 5 mph.... any thing past 5 and well you can't get there I tried to explain my prob as best as I could, my neighbor thinks it could be a loss of compression or a problem with the C clip on the carb.... ( The carb needle did have to be replaced 2 months ago ) The bike is only 5 months old, and just has weekend riding on it ( it's basically new ) so I don't think it could be a compression prob, Any help is MUCH appreciated!
