Hondabond on mating crankcase surfaces

[AshimotoK0]

Anyone  got any comments to add to this USA site post and Hondaman's comments from his book (highlighted by me in red) on the attached image?

For what it's worth, Trig doesn't put it in the middle, ever. Trig says it was put on the middle originally because it was put on by a  rolling machine. But, what Hondaman is saying doesn't make sense or read correctly anyway.

I thought that too Julie but someone came around today who has assembled lots of Honda engines and said the factory applied it in the central areas, so he does too. I gather Kawasaki shop manuals tell you not to apply bonding paste in those central areas on their 4-cyl engines.

I have no idea about Kawazaki engines Ash, all I know is Trig never has. Hurry up though, whichever way you decide to go or your Honda Bond will be dry on a warm day like this before you mate the cases 😁😁😁😁

If you apply the Hondabond in a layer so thin that it's barely visible then I doubt it would
 make any difference  🔧🏍

Just to add to this, The kawasaki Z400J I am currently restoring has the sealing compound on every joint face including in the middle of the cases. Considering the engine only has 300-odd miles it has never been apart. The sealing material is like a black silicon and it's been dripped everywhere, under the main bearing shells in a couple of places, on top of the main bearing shells in a number of places, over the roller bearings in the gearbox and its oused out internally around the mating joint on the inside as well. I think I'll take a bit more care when it comes to rebuilding it!
