Anybody Else Struggle With 348 Exhaust?

Well, I'm starting to reassemble the 348. Have a new piston in a freshly bored cylinder, got the cylinder and head on today.

Now for the god-forsaken exhaust...... I struggled getting it off when dissassembling the engine, in fact, I couldn't remove the exhaust until I removed the clyinder first.

Today, I forgot to position it in place between the frame and back wheel, and between the front frame downtubes, before installing the cylinder. Can a guy get it on by first removing the rear wheel and rear fender [ thus allowing room to manouver it fore and aft whilst getting the front pipe aligned and bolted up ]?

I don't really want to have to remove the head / cylinder again just to get the exhaust back on.........I'd rather remove the rear wheel and fender if necessary. Anyone got an easier method? It's like a puzzle of sorts.

Also, I want to install an ignition condenser [ inline with the black wire going to coil ] up under the frame / fuel tank. Does the condenser on the stator have to be disconnected first, or will it hurt to have two condensers connected at once? What rating, or microfarad does a 348 require?

Thanks,

Spoke.....

Hi

pipe should feed in from the front fairly easily,

disconnect the original condensor and remove it

use any car type condensor the only criteria i look for is that it already has a bracket on it as i'm to lazy to make one

Everyone says to remove the old condenser when you add one at the coil, but I didn't on my 349 and it starts and runs well!

I don't doubt that it can do that, but i would remove the old condenser. One way a condenser fails is to go into a "high leakage" mode, which can allow more of the ignition energy to leak out to ground instead of being used in the coil to produce a nice big spark. I would imagine that having 2 condensers in the circuit increases the total amount of leakage possible (i have not tested this, but am just guessing. I should dust off the oscilloscope and try to remember how to use it...screw it :dunce: ). When one of the 2 condensers fail (goes into high leakage mode) the second condenser is not going to help you.

I am just a hack that a number of years ago was a pretty pathetic physics student, so if i have misstated anything, someone please correct me!

Dont worry, someone will, if required.

I removed the condenser wire from the points and just tucked the pig-tail end of the wire up out of the way, leaving the condenser in place on the stator. Wired a new condenser under the tank next to the coil on the 348. Seems to work.
