Does anyone have one and is it any good?  I did purchase one online and am chomping at the bit waiting for it to get here, Ha!

I have the Clymer but not with the "Yosh secrets".

Curious to what they are?

even if all you do is try to replicate the picture on the cover you will have done well

Thanks gentlemen!  I will most definitely post photos of the "secrets" when it arrives.  Digging on the internet yet to maybe get a glimpse.  Gives me a fuzzy good feeling about the articles it contains!  My wife just purchased a couple 360 twins for change 2 days ago so I'm running out of room, Ha.  His and hers projects if you will.

Yoshima ≠ Yoshimura

 "Kazou Yoshima was the owner of Ontario Moto Tech. He created a name for himself building up CB400Fs for racing in the mid 1970s. His best street kit was a 458cc overbore, a mild but nasty cam, some head work and a very very beautiful 4-1 pipe that was light and very snug around the engine for maximum ground clearance. Cycle magazine did an article on him way back when, calling the OMT CB400F his "Business Card"."

Thanks Ranger, I fat fingered the phone.  Edited title in original heading.

I have the standard "maintenance" edition with the full color wiring diagram.

It's proven itself remarkably unremarkable.  The haynes manual has better information.  Neither can compare to the downloadable manual found in the forum.

Will be interesting to compare versions!

Bomber, I too have the same and am curious.  It was only $10 and I figured I can skip a couple cheeseburgers and a coffee for some reading material.

I have this book and followed much of the performance advice around 1980 to build up a 466. Still valid info but most if not all the suppliers have disppeared...

It's here all the way from Ontario!

Doesn't look to me like it's any different to the standard clymer with the full color wiring diagram? (has the exact same 'performance improvement' chapter?).
