50mm Big Bore Elite S Build

No gasket between cases. Honda bond is like permatex.

Honda bond gasket sealer must add thin layer on both half case. Install a crank into a left side case it is not easy without special tool or case can damage. torque wrench 7.2 lbs

Greetings:

Juicy pics, y'all. Thanks for sharing.

The hole in the shroud is, uhh... Well, air going in must come out. I'm convinced Honda-san blows it there to prevent carb icing. You Aviators (and Northerners) know what I'm talking about. The foam is likely for noise abatement.

The bigger bores still have to keep the plug tip central. I agree they should come with redesigned shrouds, but don't expect that'll happen when you pay so little for that fine casting and machine work. I used muffler tape around the part of the plug hole that became exposed.

VeeDubh, are you sure about using a pliable gasket maker between the case halves? Isn't the gasket thickness a critical factor? I won't argue with success, but maybe that's specific to the crank you're using?

referencing the SA50 manual the 88-93 engine is the only engine that has the gasket between the crankcase halves.

94-01 case halves get honda bond, no gasket.

Sorry I have not posted in a while. Holidays are a busy time around here.

I have a few pics of my new VDO cyl temp gauge. Enjoy.



Looking for a good place to put this gauge.

Sharpie marker the circle in the right spot. Time to get the sharp scissors






The hole I cut was so perfect, I may not even need any mounting hardware.

I will wire up the sending unit tomorrow. Until Next Time.........seee ya.

Why can't anyone make a bbk head, that lines up with the spark plug hole?

The plastic kinda gets in the way by the exhaust too

I plan on cutting out some around the flange. get the scissors ready

And * is there a hole on the back side of the plastic for?


I am also confused about the foam located inside the fan shroud. What is it for?

The bigger bore head sits higher. Very easy to just cut plastic with dremel or scissors.

Hole in the back side of the plastic is to vent the aircooling air out, after it has passed through the fins of the cylinder.

the foam inside the a/c cover is to pickup stray particles sucked up through the fan opening, doesnt pick up anything major but does its job. this way you get a tiny bit amount more airflow instead of dirt thrown at the bore.

I like your clutch cutout, looks good. very nice overall

Burnt Toast likes my build I'm not worthy

Man that makes my whole day. I have read over BT's builds sooo many times.... he is the reason I got an elite S.

Thanks to everyone who comments on my build. That is why I post, to get feedback from this forum. (good or bad)

Keep the comments comming.

Are you going to port the boost port in case? More performance and it gets the fuel/oil mixture up to piston to cool piston crown. The oil pump plug is from VTCycles for something like $10.

in one of the pics i can see a mark that looks like its for boost port porting

Yes you did see boost port marks!

And today I have the Magic Stick (The all pupose cutting tool for EVERYTHING)

So let the case cutting begin.

More pics of boost port matching. (and one pic of the magic stick)

that manifold isn't bad once you smooth out the sharp edges.

Well, if dem0nk1d says the CT needs smoothing, I'd better get to it.


Ahh yes .... I see the edges that I must smooth out



I knocked down the edge, that needed to be smooth, with a quick scribble of the Magic stick.



The magicstick scribble was not as smooth as I wanted....so I broke out the sand paper.



Then I hit it with as small brass brush. Is this smooth e- nuff?

[Trafficjamz]

Since I am making the CT mani super smooth, I figured it would be a good time to smooth edges of the intake ports in the case too.

[Trafficjamz]

I dont know why there is a little extra ridge in the exhaust port of this 50mm jug......so Got the magicstick back out......




Do you guys see what ridge I am talking about? Hopefully it does not serve any purpose.






That looks better to me

[Trafficjamz]

Here are some pretty cool pics of the jug line up with each half of the case to show the boost port from the inside.





Well that is all for today guys.
