I have a question regarding the stock exhaust: After "uncorking" the motor should anything be done to the stock pipe? (ie: cutting the baffle?) :thumbsup:

I put a FMF on mine. Keep in mind you are not going to much much more power out of that motor unless you bore it. Still it's a fun DS bike.

screwing with that baffle will make it louder ... thats it ... no power increase, just louder ... leave the stock pipe alone, or replace with aftremarket pipe ... and make sure you run a spark arrestor ... :thumbsup:

There's a guy on Ebay unloading WB E2 pipes. Brand new in the box, I scored one last month for 230.00. This is the pipe to get for a 650L. It has a 96db core, and spark arrestor. It takes seconds to replace that with the open cap if need be.

Just query Ebay for 650L pipe and you'll see. The guy says in the description that it may need the mount adapted for the L, but this is not the case, you just use the turn signal mount and it lines up perfect. To 10 minutes to install.

that is a very good price, and the pipetests usually pick the White Bros as the all-around best power gain, too :thumbsup:

Removing the baffle yields a small increase in top-end, most noticeable during long sandy uphill climbs with a teraflex.

It is a small increase, however.

Shame, he must of sold a dozen of them. Anyway, anybody on a budget can get a decent, used pipe. It's a simple matter to repack them. I think a lot of 650L miss out on the bulk of the used stuff--search for XR600, all but a few years bolt straight onto the 650L. If I couldn't have scored the WB, I think the next best pipe is a Supertrapp, or any of the similar pipes with the tuneable disks. I regularly see used Supertraps for the 600 go for 50.00 to a 100.00 bucks, and they work great.

IMHO it sounds much better without the baffle, with it all I can think is VW. :thumbsup:

No matter what they say you are not going to see any type of major power gain. But it's going to sound like it does,and thats what makes us happy.

If you do the standard carb mods and change to 55/158 jets, the bike will run great with the stock pipe; maybe about 10-20% more power. If you go to an aftermarket pipe, you're going to have to bump up the jets. I just put on a Supertrapp IDS2 Quiet and will be putting in the 58/165 jets this weekend and report on how it goes... The bike was running too lean at 55/158 with the Supertrapp can.

I found a Yosh comp can for an XR 600 that bolted right up, and works fine. Some of the Yosh cans have an end cap that has the provision to put smaller output tips inside, with spark arrestor. The thing was in the Parts Unlimited close-out catalog at my local dealer. Paid $175.00 for it. As is comes, it's pretty loud......

Cool! It's hard beat a Yosh for performance.
