Crossover Corrosion

[Lucky_Lou]

My crossover pipe is looking a bit  corroded i have a new one to fit the question is will i damage the down pipes if i try to change it or should i wait for it to go altogether.There are no clamps as it is held firm by the glue of age.......

When I tried to remove the exhaust system from my '81, the entire system came off as one piece, then it took the better part of an afternoon to get all of the pieces disconnected from each other .

So it can turn into a project the first time .

Be sure to apply an anti-seize compound to all of the pipe joints upon reassembly .

Hey, Lou...

As you have a new x-over pipe, it would be fairly simple to use a Dremel cut-off disc (or similar) to make a couple longitudinal cuts on the old pipe where it joins the header. Perhaps even saw through the middle of the x-over to allow a bit of twist n' turn to remove the old bugger.

Try some PB Blaster -or a 50-50 mix of lacquer thinner and ATF- as a rust buster after making the shallow cuts.

Obviously, you'll need to remove the headers to install the new, shiny x-over. Does the new bit have the "bolted tubes" as the OEMs?

Luck with the header clamp nuts

I didnt know i would need Black Powder fortunately i have an ample supply(you were only supposed to blow the Bloody doors off springs to mind.... ) i bought the Cross over pipe when i first bought the bike expecting to change it during the rebuild but didnt need it at that time as the exhaust was sound with the new silencers and "mod" to the end of the down pipes the pipe.The one i have is from Motobins it has an Allen screw clamp built on i dont know if thats OEM or not.
I was thinking i would be cutting the pipe to do it,i re assembled the Exhaust nuts with copperslip so hopefully they should come off without to much effort.I have a couple of big rides coming up so i think i will leave it untill after them,Thanks for the input.

Mine are in similar condition.  My limited experience with working on exhaust systems has convinced me to live with what I have until it fails, then replace the headers and crossovers at once.  I know that even if I did pull off removing the crossover and replacing it, the nice shiny new piece would make the OK-looking headers look all the worse.
