Bike: 2002 WR426FHi!New to the forum but longtime reader.Long story short, bought a wr426 a year ago. put around 20h on it since.It always starts first (or second when cold) kick and runs great.When doing the starting procedure theres a firm resistance felt in the kick lever and I use the decomp lever to get it to TDC.However, if I dont use the decomp lever and just put my weight (75KG naked!) on the kick it will fall through in a couple of seconds without using the decomp lever. It does not matter if cold or warm, it will fall through eventually.This is why I suspect something is wrong. But on the other hand it powerwheelies in the lower gears and feels strong.More info:When I bought it i adjusted the valves and could hair a faint whosh of air when I forced the kicklever past TDC without using the decomp lever, but since it always started fine and ran great I didn't think more about it.So this is an old bike and it runs great as is and always starts first kick, what should I do? Tear down the engine and ...? Or just hope it doesn't blow up and ride it as usual?Knowledge and advice much appreceated.
