79 XS 1100 Special -
EX - Welcome to the site. Take a look in tech tips under "Modifications". There's a thread there labeled "Jetting Recommendations" that should answer your questions.I think I have a loose screw behind the handlebars.
'79 XS11 Standard, Jardine 4/1, Dyna DC1-1 Coils, 145 mains, 45 pilots, plastic floats - 25.7mm, XV920 fuel valves, inline fuel filters, speed bleeders, Mikes XS pods, spade-type fuse block, fork brace, progressive fork springs/shocks, manual petcocks, 750 FD, Venture cam chain tensioner, SS brake lines -
And to add... you'll never get all the power or get it jetted right without some form of resistance from something resembling a muffler of some sort.
TodTry your hardest to be the kind of person your dog thinks you are.
You can live to be 100, as long as you give up everything that would make you want to live to be 100!

I put on a set of megaphones from JC Witney - the longer ones that are slip on. I have been told my bike was dang loud! I like the sound and no, under any circumstances could the sound of the Timemachine be confused with a hardly. I have heard of guys using the exhaust tips from a VW Bug. Ya I know that dates me. Seems like it would be loud!!!

I have a 4-1 I was thinking maybe I could cut open a used sportbike muffler and take out a few things and get a nice little rumble or is there a single muffler I could buy I like the look of the jardine oval can that comes with a header in a set but I only need the muffler it may be because I am young but I just want people to know I've arived79 XS 1100 SpecialComment

If you take a tape measure to the "collector", the part your megaphone and header meet, you just need to buy a muffler with that diameter. Almost ALL aftermarket pipe builders will sell just a muffler, so that should be easy.
As you get older, you learn that STEALTH is a better option. I still ride fast, but I like to be gone BEFORE the cops hear the bike!I only need the muffler it may be because I am young but I just want people to know I've arived
