Hey everybody,
This is my very first post here although I've used the forum for tons of help in the past. One thing however is that I couldn't find a really awesome set of dumbed down general instructions for replacing my starter clutch and clutch.

My bike is a CB750 K6
My problem is, a bike that won't start due to a worn starter clutch (I think!). All I hear is a super weird spinning sound when trying to start. I've checked practically everything else (battery, plugs, carbs, gas, etc.)
My clutch also slips from time to time so I thought I'd just swap it for a new Cycle X kit.

I'm not the most mechanically inclined but I am determined to do this myself!

All I need is for someone to tell me what tools I'll need for the job (special if any and regular) and how (the more detail the better) to do the job.

I know it's asking for a lot - so anything helps!
Thanks

Howdy! :)

Well, first you're going to want the shop manual and the parts list.
Both are available here:http://www.honda4fun.com/materiale-documentazione-tecnica/shop-manual
The common service manual is useful too.

You're going to need one of these for the clutch nut:

And of course gaskets & seals for the side covers and some other odds & ends.

Download the manuals and read through the procedures and do some forum searches, there's TONS of info here about clutches.  :)
Do you have a copy of the Honda Shop Manual or Parts List for your bike? Get one here:

The 3 screws holding the starter clutch to the alternator rotor are staked in so you'll probably need to drill those stakes. No biggie but you'll need an inexpensive alternator rotor 'puller' first. And you need an impact driver to get them out. Don't try otherwise! If you strip the screw heads you'll be in for a fight. Get the after market overhaul kits with all 3 pieces or order them separately from Honda. Also a torque wrench to insure you get the rotor back on to the correct tightness so it doesn't slip. The surface on the gear that the rollers roll on may have uneven wear too. May be a good idea to find one in better shape (NLA) if that's the case.
