Bug exhaust

[Pam's buggy]

I have more dumb questions.
I got points and condenser for the 009 dist.
Rebuilt the carb.
Put together and she fires right up .
To my dismay......under the header wrap,the pipe is rusted away.


The motor is a f series.
But it looks like a duel port head.
Will a 1600 exhaust Baja style converged pipe fit
I read that the cylinder are wider than the 1300.

And how do I tell if I have fresh air or stale air.
Looking for a exhaust. But want to get the right one.

Doesn’t matter, Head’s are the same width between exhaust ports. Any small difference in width from longer/shorter cylinders (pretty much all within a couple mm) or flycutting heads to raise compression is pretty negligeable in the grand scheme of things. Headers are just bent tubing jig welded together. There is probably more dimensional variation between similar headers than there is various engine combos. That’s what slip joints are for. Any exhaust should fit just fine.

Just an FYI - someone like me has no idea what you posted before, so include all info if starting a new post.

1200s are narrower that a 1300-1600. If you have a stroker, then it may be wider.

X2, What andk5591 said, or start a build thread and keep it all in one location.

Fresh Air-thinking heater boxes that put fresh air into the car. Not sure what stale air is.

The heater box mounts to the front exhaust port on each side and then connects to the header with a clamp. A flexible tube would go from the fan shroud to the heater box, then through a large corrugated tube to under that back seat.

Like this:

If you have J tubes there is no heat in the car the j tubes look like this:

Thanks for the info everyone.
Mine is on a sand rail.
I see what you mean about the fresh air .
Mine has the ports on the air shroud.
Obviously the rest is gone. I wanted to be sure that there wasn't a difference in the heads.

From what I read the f series is a mid sixties,
1285 /1300 motor.

The compression seems low in it .
Not sure if I will rebuild the top end, or find another motor ..

She is kinda rough but my girlfriend really likes it. Got it cheap enough..
Thanks

Someone will pipe up on this. But I don't know if you can get 1300 P/C anymore. I couldnt find them. If the bottom end seems good, you can get 1600 P/Cs for it, but the heads will need to be machined for the larger cylinders or you need to find a set of 1600 heads. I am in the middle of doing this right now.

I'm not sure what you mean about 1300 pc.
New to the bug motor.
So please enlighten me.

I haven't checked the compression with a gauge.

I've read that I may have a motor with 5.5 ratio.

How much would that read on a gauge?
60. 70 psi. Or lower.

I got pipes ordered
And intake off read for new gaskets and boots.

Gonna see how she runs.

Pc means piston and cylinder
Whatever the number stamped on the case, has no bearing on what size engine you have now. Especially since it started as a 1200, but now has dual port heads.
Checking compression is not going to tell you your static compression ratio.
The only way you will know for sure what size engine you have is take off a head and actually measure the bore and stroke.
With the crappy aftermarket parts offered today, almost every exhaust is going to require some sort of tweaking to get it to fit right.

Sorry about not being clear.

Single port head

Typical single port engine

Dual port head.

Typical dual port engine

Ok I got you on the PC.
I understand the single duel port heads.
Thank you.

It's probably got 1600 cylinder and head
Since it's duel port.

I've been building motorcycle engines for most of my life. Mostly triumph and Harley .
And a few dirt bikes when I was a kid.
I got a old fxr that I'm putting together now.

These bug engines are similar to a bike ,
Being as the cylinder comes off.

Well I guess I am about to learn a new set of skills.

Alright great class of instruction.
I bought a empi pipe.
Four individual pipes that turn up and the collector goes on to the pipe.
I got the one with a u- bend,that turns down to keep the rain out.

It fit pretty good .
Just a bit of tweaking to get the collector on.
Gonna go to my pops and look through my pile
Of motorcycle pipes and get a baffle.

Looks pretty good.
Pam really likes it.

I just got the ignition straighten out.
After I get baffle in I will work on the jetting.

Thank you everyone.

I'm glad I found this site.
Lots of knowledge on here.
This is a new animal for me.
I really appreciate all of the input.
