stock exhaust question

[Debbie Barry]

I have a 01 KLR, I did the airbox modification I found on the web where you cut off the top and remove the screen. I am running a 160 main jet, I have the adjustable needle from a dynojet kit in the upmost position and a stock exhaust and I am getting about 43 mpg. The bike has so much more power than stock it is amazing, I weigh 210 and have the 16 tooth front sprocket, if I whack the throttle on takeoff the front wheel will leave the ground a couple of inches. I do think that my stock pipe is getting louder though, I am at 5000 miles and don't know if this is normal or not. I had a Cobra pipe, took off for a weekend with it riding about 1000 miles and when I came back it was so loud I couldn't stand it, the screw holding the baffle came out, the aluminum can was all distorted to the point at which after removing the clip I couldn't even remove the rattling silencer to pack it. I called Dennis Kirk and told them that it fell apart in less than 1 month and they said to mail it back, I gave them my CC number and told them to ship me the new Supertrap and they agreed, that Cobra pipe was a peice of crap I only hope I have better luck with the Supertrap.   John 01 KLR650 81 R100s

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 -----Original Message----- [b]From:[/b] Fred Hink [mailto:moabmc@...] [b]Sent:[/b] Thursday, October 05, 2000 11:32 AM [b]To:[/b] KLR Owners Group; Zachariah Mully [b]Subject:[/b] Re: [DSN_klr650] Stock exhaust question ----- Original Message ----- [b]From:[/b] zmully@...

It leaks a lot from the two joints at the header and at the can, and is becoming unbearably loud.   [b]Two thumbs down on Cobra from me too.[/b] [b][/b]  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.   [b]The only difference between Stage 1 and 2 is the size of the main jet.  It is easy enough to check out by removing the float bowl and main jet to see what you got.[/b] [b][/b]  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)???   [b]A jet is an orfice and you change them by exchanging them.  You might change the needle in a stock carb by shimming it but since you have the jet kit you should have an adjustable needle.  To change the needle jetting you move a clip up or down on the needle.[/b] [b][/b]  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....   [b]It takes all of 10 minutes to change the exhaust.  So try it and see for your self.[/b][b][/b]
