Hey folks,
I finally got around to putting my glasspack exhaust on. It sounds very good, IMO. mellow but beefy. A pal told me it was pretty loud, but I don't think it's too bad, though I do have confirmed hearing loss.
Anyway, A brief rundown of the entier mod follows, and if anyone wants, I can write it up for the tech section.
Got a 17" long glasspack (AKA cherry bomb) from jegs (on the internet). This model has an ID of 1.75 " all the way through.
I welded a 1/4-20 nut to one end and stuffed a thumbscrew in there, and another nut on the outside with some red loctite. It has not fallen off yet. I put two cuts parrallel to the axial direction of the pipe at one end; each cut went about half way down the uh, thin part of the glasspack ~1". This was to make it easier to fit over the header. This may have been a bad idea as it
may be causing an exhaust leak. It went on very very easy.
After removing the stock muffler, I put a bead of red High temp gasket maker/sealant around the end header pipe, about 1/2" from the end.
I stuffed the glasspack on there and afixed with three strap clamps, the kind you can tighten with a screw driver or a socket wrench. I added one to the muffler support.
This particular glasspack model fits very nicely onto the the stock muffler support.
I rejeted accordingly, though I need to do some tuning.
The bike is noticeably quicker at all ranges (so far as I can tell... only done about 10 miles so far)
I also did an air intake mod. I got a KN "R-1260" tapered air filter.
It bolts right onto the carb. BUT, what I had to to to make it fit:
1) yank the stock airbox and cut most of the top of it off. I used an angle grinder to cut out the neck and about a 2" square rigth below the neck.
2) threw out the batter box. angle ground two slits into the front of the air box. Used a long strap clamp to secure the battery to the front of the airbox.
3) moved all the wires around so the filter would fit.
Believe it or not, it looks pretty good. I will try to get pics & sounds soon.
Also, I bought a drag specialties (ists?) breather hose filter. I zip tied it to the battery strap clamp. One could feed this hose into the air filter, but I don't think it's long enough. If you want to go this way, make sure you get the "R," not "RC" version of the filter as the RC has a metal cap and the R has a rubber one.
Thanks for readin'!

PS, main = 155, pilot = 47.5, white needle spacer is gone and repalced with 2 3mm washers; PMS whatever it was... I still need to tune it. I at 4000 feet above sea level and I bet I'm running rich, but I like backfires...
