just got my new trapp and looking for some insight on how many discs to run. im the second owner of the bike and not sure if the carb has been jetted. at first i installed 8 discs the went down to 5 what the book reccomends and cant tell much difference between the two. i dont see any black on the fender from either setup. and i didn't hear any popping from the exhaust when i let off the throttle from either. have only ridden about 15 miles though. any help on this would be great. if it makes a difference its a 95 with 8200 miles. and with this setup how should i have the pilot screw adjusted? thanks...mitch __________________________________________________ Do You Yahoo!?

I too have recently installed a trapp (IDS) on my 95. I'm running a 10 disks with a K&A filter and a DynoJet kit (140 Main)@ 7000 ft elevation. Low end power and throttle response have greatly improved, but now I've got a flat spot at the top end. The best way to tell is to read your plug. It should be a nice tan color at the tip of the porcelain, below the base of the center electrode. If it's black then your too rich, white (colorless) then you're too lean. If anything, your bike has leaned out. Be careful- If your too lean, you can fry your engine, but I doubt just the addition of a trapp would lean you out that bad. Also different circuit in the carb affect how the bike behaves at different RPMs. There is a chart at http://www.dualsportnews.com/klr/CVK40.htm that explains in detail.

The disc set IS the spark arrestor, you need a closed end cap for the last disc (ie there should be no way to insert a broomstick into the can). Contact Supertrapp, they should sell individual parts. The "end cap" is just another disc without the center cut out, NOT the cast aluminum turn-down canister cap that fastens with three allen bolts to the outer canister. Devon lbank84@... wrote:

It will run way too rich and the bike will perform horridly. My bike came with the 4" race core 'Trapp on it with what looked to be three discs in. The end of the can was pitch black from running so rich. When I finally ordered up some more discs and pulled it apart, I found that not only were there only three discs, but the disc closest to the core had been tack welded solid. Essentially the first disc was blocking the core almost entirely. The bike also sounded like a broken lawn mower. I added 8 discs and a heat shield, total of 9. Bike instantly ran better, if a bit lean (carb screw mod isn't done yet). It seemed a bit loud....I found out later that it has not a single scrap of packing in it. It wasn't unbearable but it was loud. I eventually repacked using stainless steel wool safety wired to the core. I don't have many miles on that repack yet, but it sounds great and hopefully will hold up. Run it with 6 or 8 discs, the bike will thank you for it. -- ___ ______ _____ __ ________ ___ / _ |< < / == / ___/__ / /_ /_ __/ / __ ____ _ ___ /__ \ / __ |/ // / ****/ (_ / _ \/ __/ / / / _ \/ // / ' \/ _ \ /__/ /_/ |_/_//_/ == \___/\___/\__/ /_/ /_//_/\_,_/_/_/_/ .__/ (_) 8600 miles*Russel Lines*Supertrapp Race* /_/ http://www.kingsqueak.org/klr650/

I wouldn't mess with it. Your likely to tear it up pulling it apart. And then need mo money to repair it. I always thought the supertrap was nice cause it still muffled ok with the disks versus other pipes with no packing. --- In DSN_klr650@yahoogroups.com, "mike chartier" wrote:

The bike won't run right with one disc. Are you asking because it sounds offensively loud and you and to make it more reasonable? If you are comfortable with the sound level and happy with how the bike works, don't mess with it. Basically, what Chris said. 6-8 discs will work well if you turn out the pilot mixture screw a bit. I've taken apart a few of these things. All but one have gone back together. So far the most reliable way I've figured was using a dent puller to get them apart. If you try to hammer the core out of the muffler shell, it usually damages the core beyond repair. If you repack it with stainless wool, it should be a lifetime fix and won't need to be repacked. -- Devon Brooklyn, NY A15-Z '01 KLR650 '81 SR500 cafe racer "The truth's not too popular these days....."

HI Mike just did the repacking of the supercrapp a week ago with the wool (got it hat home depot for around 3 bucks, go to the paint section). I first removed the core (pretty tough, I used a 32 impact socket and a dead blow hammer to get it out, pushing it from the side of the slip on ie the one that connects to the pipe. Then cleaned the original packing, put some wool around and kept it in place with metallic wire (you can use chicken wire too). Then put it back in and voila: no need to bother anymore. I haven't tried it on yet tough. Total job: about 20 minutes to get the core out, 5 minutes to repack, 3 minutes to put it back in. But that's done once and for all.
