 "I want to buy a new exhaust because mines getting old."

New exhaust is always good, but for information you should be able to undo your cans where they attach to the intermediate pipe. Some are riveted, screwed or clamped at that point. Undo the fasteners (drill out the rivets) and you should be able to disassemble and repack your mufflers. Some packing choices are original type fiberglass, ceramic fiber or stainless steel.

The cans are Al. The "F1" decal can be removed with some mild heat and they polish up great. Take a look at Pat Conlans bike in in his post (the side picture). He and Leon are the kings of polish.  I have Cobra F1's (a little different model) and am in the process of repacking and restoring them myself.

Something to think about this winter

How do I remove the air box. Do I have to remove the carbs. The crank case vacuum tube is hanging and I cant get it back on. I cant get my fingers in there.
Where on this site can I find maintenance procedures. I did a search "air box removal" and found nothing.

Hi Joe
        I will try to help out if I can. First put the bike on the center stand and remove the seat, then if you look at the side of the air box you will see a 10mm bolt, below that you will see a 17mm bolt with a locking tab.  There is one on the right and left side. On the top rear of the air box you will see a 10mm bolt.
Remove the 3, 10mm bolts from the air box.
Remove the 2 , 17mm bolts on each side of the rear sub-frame (the ones below the 10mm bolts on the air box side).
The rear sub frame will "fall" or tilt down with the rear wheel on the ground.
Now you can unscrew the carb boots and unhook the crankcase hose.
The air box should now have enough room to wiggle out.

Now, just for information, this is why some convert to uni-filters. With that you have no more air box to contend with. If you keep the air that's fine, I seem to have the most trouble trying to re hook the crankcase ventilation hose, it is a pain..  It takes me a while but it will slip back on.  (I have since modified my box). Maybe someone has a simple way??  In reinstalling the box, take some time and make sure the boots are sealed all the way around the each carb. Underneath is the hardest to feel/see.

Hope this gets you started

Took some digging, but I happily found this thread.

If I purchase the duals, like you linked... Do I have to rejet the carbs? I'm having a tough time trying to get my dang rubber connectors from the air box to slip on the carb stacks. I noticed the vent hose was left loose and I'm sure this has something to do with the rough idle. Can someone post pics of their dual filter setup, along with what you did with the crank case vent hose?

Thanks in advance!

With great patients and steady hands, I was able to massage the air box and rubber connectors on... It was a PITA to get the crank case vent connected! I got it connected, but I know I WILL be replacing it soon with a better alternative. I found what looks to be a filtered plastic fitting on one of the carbs vent hoses. I looked everywhere and could not locate an opening to screw it into. Could someone explain what it is used for?

I used the tool as Dean's son had designed to get the boots on.  Worked great!

That same tool is good for lining up the vent tube so you can push it in with a big flat screwdriver.  I got really good at it after a few times.  I'm a big fan of keeping things stock.
