God help the child who grows out of everything
Hi all!
First off, thanks for all those who helped me identify the Gary Wolf Racing exhaust on my father-in-law's '79 CB750F.
(* TL/DR at the bottom)
Now that riding season is fast approaching, FIL and I have been talking and it's been decided that I'm going to be giving him the OEM 4-4 exhaust from my 750C (it was originally purchased as a parts bike anyway) and taking the Wolf pipe.
The first thing I did was remove the Wolf from the F and look into whether or not I could repack it (very loud/ringing above 4000 rpm - right where cruising speed is achieved). I got the can off and had a look inside: holy carbon, Batman! I scrubbed the baffle with a wire brush and got it all cleaned up nice, I'm going to stuff it with some Roxul rock-fibre insulation that I had laying about (r13.5 if anyone is interested haha). It's reputed to have great sound deadening properties and is fireproof to boot!
I cleaned up the can while I had it off. I just wanted to make it a bit prettier, clean up the age and scuffs, etc. You know, nothing overboard. It seems I got carried away and ended up polishing it. Oops...
So now, I have an old, crusty looking pipe with a pretty polished aluminium can; of course I'm going to clean it up and paint it (going with VHT Flameproof, probably in black).
That's when I noticed a few issues: first, a couple of head pipes are dented (about 1/4" at the deepest point), possibly from when i crashed his bike last summer... as is the collector. (Maybe 1/8").
There are some pinholes, likely from age (I spoke with Gary Wolf, which told me he made those pipes around the mid-80's for racing and that someone had grafted on a muffler) that should be fairly easy to weld up once I get the old paint blasted off.
(* TL/DR)
My questions:
1. Are the dents something that absolutely need to be fixed?
2. If so, what's the best method to go about this?
Here are some pics:
- The '79f, wearing the pipe in question.
- Removed from the bike and the can is off. That baffle is unpacked and is about 2 feet long; it goes inside the pipe to the collector!
- next 3 images are the dinged up #2 header pipe.
- A couple shots of the collector
- Finally, the nice, shiny can...it'll look real nice once it's all back together!
