I think that's where Yamaha improved things when the FJ came out. The alternator is driven off a cog, AFAIK, though still situated behind the cylinders. I've rebuilt 4 and not come across any other chains other than the cam chain and primary chain.

 

Cog? Gear my dear friend, not cog.

 

Cogsley Cogs vs Spacely Sprockets?

 

Is it a Welsh thing? LOL. COG | English meaning - Cambridge Dictionary

 

I stand by my reasoning, an engineer would never use cog..



+4



Cogs are individual teeth on a gear or separate, often wooden, pegs inserted into a wheel, whereas gears (or gearwheels) are the entire toothed wheels that mesh together to transfer torque. Cogs are often smaller,, while gears are broader,, more general components. In bicycling, individual rear sprockets are called cogs.

 

Was a real weak point, they updated the guide to use 2 mounting points not 3, but its almost like they knew it would happen as they provided an inspection hole just big enough to fish out the broken part.

Cost me $200o in rebuild parts, £600 in shipping and then rebuild costs....only to have mechanic take con rods off, not refresh teh stretch bolts and blew a con rod and now going through second rebuild

 

That's an expensive build. Did the so-called mechanic accept responsibility for his balls-up?

 

Well there is at least oine here in Norfolk UK. 1981 XJ650 Maxim, now running and riding well after much work.

 

xj650 here in Whitby, bike complete but needs recommissioning

 

There are at least two XJ650 4K0 bikes that regularly attend shows as members of the Vintage Japanese Motorcycle Club (Teesside section) mine included. They were both on show last year at many Classic Car & Bike shows including Whitby Regatta, Elvington Air Museum Cold War Wheels, Darlington Pump House Show, Croft Racing Circuit Classic to Modern Show and more. Having said that I have decided to show my Honda CX650ED at most of these shows this year, starting with yesterday's Croft WMC on the VJMC stand. My good lady accompanied me on pillion.

 

Nice one, I am keen to join the fun, as soon as I unravel a wiring gremlin that is killing my battery. I am offering fish and chips twice to the genius who can trace it!
