stock exhaust question

Korggers- In my last email I recounted my experience with a Cobra ISDE exhaust and how much I now dislike it. It leaks a lot from the two joints at the header and at the can, and is becoming unbearably loud. The PO had installed a Dynojet in the bike as well as the pipe, but unfortunately I don't know how he set the jet kit and I don't know whether or not it was Stage 1 or 2. The PO gave me the stock exhaust which is in mint condition (about 4k miles on it) and I was wondering if reinstalling the stocker would mean that I would have to rejet the bike (I assume I would). If I have to rejet the bike is there any way to use the existing jets in the bike and shim them or something (pardon my ignorance as to how a jet works)??? I really want to go to the NJ Dualsport ride on the 21st, but I am worried that I won't pass the exhaust inspection.... TIA, Zack 1991 KLR650 "Buster" 1986 Concours

Thanks Fred!     What I am wondering is depending on which jet I have (Stage 1 or 2), I will have a jet that is larger than stock... And if I toss on the stock exhaust, I will then be running rich as I would assume the exhaust is now more restricted with the stocker. So should the jet be shimmed up or down? And how would I be able to tell when I have it properly adjusted? FYI, my airbox has been opened up as well.   Thanks, Zack 1991 KLR650 "Buster" 1986 Concours

[b]I would try the stock pipe and see how it runs.  If it runs like the choke is on then it is too rich.  If your bike is running rich you need to exchange either the main jet to a smaller number, drop the needle a notch and/or screw in the air screw a quarter turn or so.  Check the KLR web site for a great guide to getting your getting right.  [/b] [b][/b]  [b]I doubt that your jetting will be too rich as the stock jetting is usually too lean to begin with.  Try it and see.  I bet it runs just fine.[/b] [b][/b]  [b]Fred[/b] [b][/b]

Eric, May I pass your comment along to the head doctor in my psychiatric ward? She seems to think we need to iron out this multiple personality thing before I hit the streets, again. Chris, Chris, Chris and, on really stressful days, Deborah
