Thanks for making this clear. When I bought this bike it needed much more work done than this. Right now it runs almost perfectly but because it required work in general, I was not afraid to do this repair.
I did worry about locking the crankshaft in place using the bolt because it's on the other side of the engine. I looked for many ways of locking the crankshaft but I failed to unscrew the nut. After locking the crankshaft with the bolt it turned out that the flywheel nut wasn't that tight.
I tried to be careful putting it all back together and the bike runs great but I agree that it's always good to have the right tools.

Thanks for bringing it up here :)
