Cored Cans
Posted: Mon Nov 19, 2007 4:01 pm
After seeing the excellent job Pierre had done with his std Falco cans 
I also wanted to try a conversion job. I love the look of the std cans on the Tuono, but wanted the real "V" twin noise to go with them. So after doing a bit of research on the AF1 site and a fair amount of fettling here's where I am now.......
Managed to blag a pair of RSV cans of fleabay for a ridicous price (£40 on a "buy it now", I nearly ripped his arms off!) once I'd applied some Duct tape to protect the finish I then set about removing the rivets that hold the can together, some came out easy others............. well you know.
Once the rivets are removed the cans come apart reasonably easily, You then have the nice task of cutting off the end can, but with a bit of time and patience they both cut off quite easily.
Now the hard part (sorry no pics) using a masonry bit I drilled around the edge of the CAT to reduce the effort required in knocking the crap out of it, finally (about 45mins) the cats are removed using a chisel and a big hammer and the remaining holes are cleaned up (this is what takes the time)
Wiser more knowledgeable people than me now say you are left with a 65mm hole, at each end, but my hole (dont go there.....) was 70mm at the CAT end and 65mm at the outlet, so I had these perforated tubes made up with a 70mm collar
You can see the idea, now a couple of spot welds and some exhaust matting wound tightly over the tubes , a bit of trimming to mate up with the outlet and we should have lift off.
I'll post more pics when completed. As you can see my garage (shown) is tiny so when it rains I have nowhere to work, my Yamaha was removed from the garage just to do this job. I'd kill for a workshop like Pierres
