Ordered the Baja Designs drop down taillight/license holder, Maier MX rear fender, and IMS smog block off kit, all should get here this week!
One quick power booster is to get rid of the stock exhaust and put an aftermarket slip-on exhaust, replace stock filter with high flow air filter, and desnorkle the air flow thingy under the seat....theses make a big difference in power. Finally, an even more noticeable boost is the infamous "Dave's XR650L carb mods" talked bout in this and other forums like Thumper Talk.

Good luck...have fun riding you BRP!

Laugh Mikuni and "Dave's Mods"

I've done Dave's Mods, very easy to do, but can't report a "significant" increase in performance. No second gear wheelies here. Better running and throttle response, but, in cool temps the bike is a bitch to start. Close to freezing on a trip I had to get a tow start by a DR650...Now if that ain't embarassing...

Looking at the Mikuni and have read old reports that the bike performs well but nothing recent. I'm thinking about spending the money and buying the XR's Only Mikuni pumper.

WTF, it's only money. Right?

Garrett

Garrett:

What jetting and altitude are you at? What you are saying (I am assuming you did the other mods in addtion to Dave's Mods: filter, pipe, desnorkle) is that you saw little change in power? This is somewhat surprising, as we know that the stock jetting comes lean...take a look a your plug's color...may dive a hint on why you don't see gains in power...

I had the same problem,bike would not start when it was cold out. I fixed that when I put an XRs only flat slide non pumper on the XRL. Its probably my number one mod that I have done.

Mikuni

Hi Guys,

Thanks for responding. I shimmed the needle with an .024 washer, drilled the slide 5/32, UNI filter, de snorkeled, stock muffler, no smog crap. Plug looks ok. I'm at 3800 ASL and after consulting with the ThumperTalk jetting guy, Eddie Sisneros, left the jetting stock at 150 main and 50 pilot. I'm thought the Pilot might be too lean but it does get fuel with the choke on, you can smell it, but it takes a while to fire and sometimes just won't start. It's a workout for my starter and I'd sooner not burn that out constantly trying to start the thing.

As I said the mods worked to a degree, but I didn't see the gains that have been reported. It's better but only marginally, mostly in thethrottle response. After reading reports from others on starting in the cold, and the adjustability the Mikuni has I thought I'd try that.

Goblin you seem to like yours and I've heard others say the cold start problem is history after the new carb is added.

Goblin, is the carb you have the same as the unit offered on the XRsOnly site?

Thanks

Garrett

you don't need a different carb. An XRL in good shape, tuned properly should start very easilly with the stock carb, other than the commonly discussed issue the ocurrs after sitting for extended periods of time.

Your jetting would be lean definitely for aftermarket muffler, maybe is ok for stock muffler. If it doesn't start well, make sure compression is good, fuel is fresh, valve lash correct, if all that seems good then try a richer pilot jet.

Thanks. Fuel always fresh as I ride regularly. Doing a leakdown check in a day or two to see if the internals are proper. Valve clearance should be fine, checked about a month ago but will do it again when I do the leakdown test. I've got a couple of richer jets coming, both Pilot and Main, so we'll see if that wakes it up at all.
