Starter Clutch Dimensions

From memory the bolt is tensioned at about 25NM.
The problem is if it does come loose and spins on the taper scouring the shaft and rotor. Common probably from way back in Z1 days and Suzuki copied it in the GS's.

that seems pretty low ? haven't got a manual yet but my factory 1200 bandit manual says 150 N-M plus its very rare for the rotor to come off the taper, they get that tight it takes a lot of force to break them free from the crank. ive seen guys fuck their crank end getting them off.

Absolutely correct @hard road torque is 160Nm for "that bolt"

I'm afraid that I have to disagree @Irish in Oz - torque is 160Nm

I should have checked the manual, did for the wheel nut and three of them so far say sprocket side.

let it go mate    tell you what, if/when I take the wheels out I'll put the spindles in from the right

Hi guys, sorry for my disapearance, the joys of being a wagon driver.

I will get the Generator cover off and have a mooch into what is going on.

Thanks for the suggestions

Note, going to sunny Mexico for a couple of weeks vacation from 24 June, I will be on it when I get back.

  Greetings members of the forum,

It definately was the loose bolt holding the genny assembly together. A quick double click of the torque wrench with some high strength thread lock applied for good measure, had the bike turning over like it and starting.

Thanks for all your input guys muchos gracias

@paddlesat16 - Be warned, that may only be a temp fix. When I had it happen on my K7, I did exactly what you did, and it lasted about 1,000 miles before it came loose again. What I found out then was that the bolt is a one time use bolt and (potentially) stretches, so I bought a new bolt, added some loctite and never had an issue again. So in all honesty, I would highly recommend getting a new bolt and fitting it with some loctite.

Whats the torque spec and size of the bolt? Sometimes the torque value includes an amount to take it past the plastic zone and into deformation (i.e. yield territory) but most often its a torque value plus an angle (say 90deg) for a single use bolt.  The torque is to seat it properly, the angular rotation provides the load to hold it together. 

I would also play it safe and get a new bolt and tighten to specification.
