The main reason most want a slip on is for more performance,more performance means processing more air and fuel.A factory XRL is not getting enough of ether.I have a FMF factory 4 titanium and I like it.If it were me,I would do Dave's mods and a good quality slip-on like FMF,Pro circuit,etc.and a Uni air filter.Then you will love your bike.Hope this helps.

Steve,
I put the XR's only on and have no complaints. Simple easy an sounds good when youhit throttle. I do not know how it compares to FMF, Big Gun and White Bros.

WB exhaust with either the E2 Series or their new XCR. I put the XCR on mine (no rejetting required - they claimed works with stock jetting - for mine it worked as advertised and no disc tuning!). I hear the XRsOnly is REALLY loud. Just IMHO.

When I was running the stock carb on my desmogged L, with a K & N air filter, I used a Pro Circuit 490 and it ran great. When I pulled the stock carb off and put on an Edelbrock Pumper I swapped out the K & N for a UNI and the Pro Circuit 490 for a Big Gun Evo-X and it ran even better. :thumbsup: :busted: :busted:

I've been trying to get an XR's only pipe for a month now but they haven't been in stock.

I'm thinking of getting the Staintune now for the sound and no repacking.

Well forget the Staintune. I was told by the dealer that it doesn't have any kind of spark arrestor and won't meet US Forestry approval.

I put on a white bros E2 without a rejet, ran fine, just adjust your mixture. Sounded great to! Never used the screen either!

A friend of mine may have a White Bros. XCR that is only a couple months old for sale. He owns two xr650l's and just bought a xr650r. One of the L's is being put back stock and a almost new White Bros. will be up for grabs as will the 650 L. Shoot him a email, fastfreddy_44@yahoo.com

Old Dog, did the edelbrock carb fit on the L, they only seem to make it for an R. Also, will it be faster than with daves mods, or a dynojet kit? thanks

Steve,
I did dave's mods, jetted, de-smogged, de-snorkeled and am running uni filter, really helped with starting from cold and removing choke. Also popping sounds quit when decelerating.

Yup, Barnum's Pro is where I bought mine, but I just went to the site and see that their listing for it has been removed. You can see it listed on the Edelbrock site here though. I didn't do Dave's mods, I went from stock straight to the Edelbrock, so I can't make an informed comparison. I can say however, that compared to the stock carb, it's a night and day difference. There's no lag in the throttle response now, it's all smooth and strong right from idle to full throttle. Out of all the mods I've done, going from a stock carb to the Edelbrock was the most noticeable improvement in performance. I wouldn't go back to stock for all the tea in china. :thumbsup:

I have xr's only pipe on my 650 r and it works good but is to loud even in the desert. Im going to try their quiet core and see if that works to tone it down if not it goes on ebay.NOISE IS GOING TO KILL THIS SPORT,it should be our main concern only a handfull can ride these bikes to potential anyways.

I run the White Bros E2 on my L. Excellent power throughout the range. As far as not rejetting, these bikes are to lean stock, with ANY slipon it just gets worse.Engine temps increase,oil life decreases and engine wear increases. I'd definitely do a rejet,I've had better results with Dave's mod than with the DynoJet kit,Also the FMF powerbomb header is a good upgrade. I actually picked up 2MPG after installing it with across the board power increase and noticably lower noise levels from idle all the way to the top. Anyone else see an improvement in milage with the power bomb?

cefox, are you running the xr600 powerbomb header on your L? Any mods to make it fit? Bolts right up to the E2?

Thanks

im with cefox. i run an e2 and an fcr 41 carb now.

DO rejet after putting on an after market slip on, ESPECIALLY with a big header!

you will cause VERY lean running, hi temps and ultimately poss eng meltdown.

Yes I'm running the XR600 powerbomb . It actually fits better than the stock head pipe with way more clearance between the pipe and the oil lines.
