Father Son 75 CB200T Rise From the Ruins

[Texasstar]

I have a TD3 and love that fairing shape. There are others of course.

Are you sure about those gasket thicknesses? 0.127mm is 5 thousandths which is shim stock/thick foil.

i asked Kevyn at comedic what the thinnest they would make...no i am not confident in those numbers...those were the thinnest gasket thicknesses comedic gave me and don't have a warm fuzzy just because...lol like the last turn at Limerock I tried to take flat out and had no more grip when I missed the apex. My instructor told me I could take it flat out if the stars were aligned and God was smiling on me so I took that as a Yes. Lol it didn't go so well...

What is the thinnest you have gone on your copper head gasket and base gasket?

Really nice work!!! really nice team!!!

 

[Texasstar]

Thanks Y'all we counldnt have done it without the do the ton team! Now we go into uncharted territory. The engine build. First up is to see how much it cost to Serdi cut the valves.

 

[Texasstar]

Wells Racing in Duncanville, Tx will serdi cut our NOS valves and head for 75.00 Is it worth it?


See the pic below our cb has "synthetic rubber mounting stubs provide completely live mounts for the 200's dual 18mm Keihin conventional carburetors. Rigidly mounted carburetors often give lean mixtures when a certain engine speed (rpm) matches their natural frequency of vibration. With carefully constructed elastic insulation, this tendency may be "tuned" out as it has been on the CB200." It looks like there is a black synthetic band inside and the mounts are aluminum.

Should we polish the aluminum areas? I am assuming the black band is the "live" part to help atomize the fuel so that it doesn't run lean at various Rpms?

These synthetic rubber mounts are round while the inlets are out of round.

The black band is just a sealing O-ring. At one point I replaced mine due to air leaks.

If you really want to get rid of the vibes with the stock carb, cut it in the middle then use a rubber coupler to attach it back together.
But, it probably wont look all that nice.

Also, just rough up in the inside of the manifold, that will help atomization. Not a mirror finish.

When I switched the carbs to aftermarket PE's I cut my manifolds end flange off and used a rubber coupler to mount them. So it would look similar to this: (attached) Except not a spigot mount carb...

I don't have a nice picture of the whole assembly.

Yea I know about the o ring that connects to the manifold what i am curious about is in the middle of the stub...the first 14mm of the stub is aluminum and then there is a 14mm black band followed by 14-16mm of aluminum the black band is halfway into mounting stub is a black band it is dead center. I took another picture.
Pic 2 is the carb stubs attached to the head
