The 650R does have an autodecompressor fitted on the camshaft, it has the same effect as the decompressor lever in that it holds the RH exhaust valve partially open at the correct time to aid starting. If you use the kick start lever to slowly push the engine through two or three cycles, the autodecompressor will disengage and you will feel quite a bit of compression resistance. Well, just lately (after about 1800miles) I don't get the "easy" start any more. It always has too much compression to just kick it over without using the manual override. I've double checked the valves and everything looks / sounds fine, bike rips and runs nice and quite. Don't get me wrong, it still starts pretty easy, but it's just a lot harder to kick. Has this happened to anyone else... how do you fix it.
