Clutch lever requires a lot of force to pull in

[spencer2004]

On my bike the clutch lever has always been quite hard to pull in and although it dosen't really affect my clutch control it does give me a pretty tired left hand sometimes. It isn't anything to do with the cable or lever as they move freely when the clutch cable is dissconnected from the engine so it must be something inside the engine.

Does everyone with the K157FMI engine have the same problem just due to a poor design or something and also is it possible to replace the clutch springs with softer ones to solve the issue or would that cause issues with clutch slippage?

Edit: sorry I was supposed to put this under maintenance.

Another problem I have with the clutch is when the engine is cold the bike tries to move foward a tiny bit when I first put it in to gear and I have to rev it a bit before I kick it in to gear or the engine usually stalls but once it is in gear it will be fine for the rest of the day. This happens every time without fail and is worse in the winter when the engine is really cold.
