rotor removal tool. Also Gaskets

[Eldrick]

When I replace the alternator later this week is it best to have a rotor removal tool?
I also need to replace, at least, the rocker cover gasket and maybe the cylinder head gasket, not sure yet where the main leak is. From which supplier will I get the best quality gasket set please?

Why do you need to replace the generator they rarely fail
If you do no the rotor does not need to come off
Head gasket can be done with engine in, there are not a lot of options for sets now but you will need the special sealing washers under some of the head nuts

Bike 'broke down' two days ago. Battery was not charging when I went on a run two days ago. It is a new battery and I recently replaced the wiring loom. I can't for sure rule out the rectifier or regulator however the AA man, (a biker too, he used to build custom machies for himself) strongly suggested the issue is insufficient charge from the [/color]alternator.
