I think I've bought the last exhaust pipe for my KLR, now I just need to figure out what to use the old ones for. Maybe a sculpture of some sort. I weighed them all so here's a rough comparison Stock- 15lbs, almost indestructible, very mellow throttle response. Supertrapp IDS2 "quiet"- 6lbs, light duty, mounting tabs are easy to bend if the bike falls on a rock or log. Not at all "quiet", set off car alarms with only 8 discs in. old Jardine pipe- 6.5lbs with accessory spark arrestor. Quieter than IDS2 but not much, good throttle reponse, durable welding and materials but rusts easily. Cheap. Supertrapp EAR- 5.5lbs with stainless wool packing. Quieter than Jardine or IDS2 but still not quiet enough. Excellent throttle response, lightweight but short and tucked in really well. Completely protected by Happy Trails OSR racks. Laser Pro Duro- 8lbs, lighter duty mounts than stock but otherwise VERY solid. As quiet as the stock pipe with a little more bass. The difference between "quiet enough to be legal" and "quiet enough that you can't hear me" which is great if you have land access issues where you live. As long as the Jardine pipe with spark arrestor. LPD has spark arrestor but isn't USFS approved. My original plan was to cut the turn-down tip and fit a supertrapp disc set, but now that I look at the thing I don't want to butcher it. I will figure out a temporary rig I can slap on the end if I get hassled about it, and throw that in my bag for enduros and dualsport rides. I had some issues getting tire clearance, and had to fit the pipe so it sticks out a bit. Still well covered by the OSR racks but will take a beating in rocks or tight woods. I am using a stock air filter, snorkel out, 4x 1" holes drilled in airbox- What jetting are people using with this pipe, and what mileage are you getting? I have a dynojet kit.

VERY solid. As quiet as the stock pipe with a little more bass. The difference between "quiet enough to be legal" and "quiet enough that you can't hear me" which is great if you have land access issues where you live. As long as the Jardine pipe with spark arrestor. LPD has spark arrestor but isn't USFS approved.

airbox- What jetting are people using with this pipe, and what mileage are you getting? I have a dynojet kit. I've got the "off road" version, so I don't think you care about what I have for jetting and such......but just in case, "L" cut, screen removed, door on, snorkel in air box K+N air filter K+N jet kit stage 2 148 main jet (smaller of the two) needle clip position 2 (from top) fuel mix screw 2 1/8 turns out from seated and of course, the almighty Laser Pro Duro I'm getting 49-50 mpg with a 15 tooth and 47-48 mpg with a 14 tooth. This is while riding 90% back roads and as usual, riding like I'm running from the cops. The other day I was standing around looking at my machine (I do that alot ya know) and took special notice of the pipe. I started smiling thinking about how great it has been in the last 16,000 miles. It hasn't changed tone and still sounds bitchin. After getting just a tad louder (I think) the first 1000 miles or so, it hasn't gotten any louder. It still shines up real nice. It hasn't loosened up at all at the brackets or the seams, so it hasn't leaked at all. I don't get any popping on deceleration. I even went down on it in a right hand low side at about 25 mph and it just got a little scratch/dent that you can hardly notice. The brackets and bolts did not budge at all. The only thing that I had to do was when the rivited nameplate finally started rattling from being loose, I drilled the rivits, and JB welded a couple of nice looking stainless steel allens into the holes. The other thing that I did while I was at it, was to JB weld another small rivit head into the little drain hole on the bottom of the pipe. It was blowing black soot crap all over the swing arm on the right side of the bike and that was bugging me. I know most other riders would not care about that at all. I love that pipe I tell ya!

Thanks for the info, though I agree your jetting might not apply. And we are using a slightly different airbox setup anyway. FWIW, if it wasn't an all-stainless exhaust I would say drill out that drain hole again. It's there so condensation, along with whatever carbon it takes with it, can drain out the low spot in the canister. As for the carbon on the swingarm, cover it in dirt. -- Brooklyn '01 A15-Z KLR650 '81 SR500 __________________________________________________________________ Introducing the New Netscape Internet Service.
