Loose? That's not good, better check the followers and rocker arm shafts and bushings.

I need some help deciding the best way to scratch my dirt bike itch. I currently ride a BMW R1200GSA. Great bike but it is pretty expensive and emotional to scratch and break so I am looking for something better suited for the mountains and desert of Arizona. I have narrowed it down to either the XR650R or CRF450X. At the age of 44 I will not be doing flips on either one. Either will be an earlier version '00-'07 set up with large capacity fuel tank. I understand the weigh vs power trade offs. Is one more maintenance intensive then the other? Is one cheaper to farkle-out with aftermarket's? Any thoughts is appreciated. Thanks for your inputs.
The XR and CRF are both really good, fun bikes and both pretty easy to live with. I'd favor a CRF (I prefer the R version) for shorter rides--say <100 miles roughly and the XRR for longer rides. The XRR is more comfortable and just eats up the miles, especially higher speed desert miles. It requires less frequent maintenance as well. The CRF is a little lighter and feels a whole lot lighter. It has more modern/competition oriented ergonomics, better suspension, etc. Power is about the same between an XR650R and CRF-X, but it's easy to make the CRF-X quite a lot faster still and the XR650R is less easy to pimp out and make big power. The XR revs slower and lower and as such hooks up better. In Vegas 2 Reno I easily pulled on CRFs out of corners on dusty dirt roads because I hooked up better. They pulled me out of sandy, bermed corners--less weight and more power.

Both bikes have a strong aftermarket, but there's more support for the CRF-X.

I had both and sold the CRF. Good bike, but for tight, shorter stuff I like my two stroke CR better and for long/open/dual sport stuff I like my XR-R better.

So for an all-around desert sled I'd chose the XR-R. For racing say the SF250 I'd take a CRF over an XRR without a doubt (relatively short race with lots of sand and whoops).

Sounds fun!

I'd buy a couple of the 1X under-fender stickers if you would agree to that.

Do you have any of the Hengeveld stickers? It was called "RIDERMAN" and had Henge in full riding gear but posed as Spiderman. I think I have a few somewhere and if I find them I'll mail you one. They are really neat.

I wonder if you couldn't get one of the So Cal dirt bike header shops to fab up a Ti pipe like the one last used? Certainly FMFand PC wouldn't consider it worth their time but some of the smaller guys might. I'd be willing to drop off one of my bikes for them to use to fab it up if they needed.

I'm not surprised they helped you. Was it Siraton? He is VERY proud of those bikes. That bike made his career and he'd got it all written down in notebooks. He's pretty good about sharing too. I dropped my bike off there for some work, alot of work really, in about 2006/7 and he found one of the 1X sticker kits and stickered my bike all up because he was bored and had not much to do. Nice guy...

Let me know if I can help.

There are certain things that I will need to settle for a close match or locally modified replica (ie suspension), but as it is early days I am still hoping to find everything. Slickwill has helped with some detailing so far and I have replicas of the sponsor graphics being made here in Oz, and Precision Concepts/Works Connection/JCR and Pro Circuit have been a great help so far. I have an original scan of the under fender 1X decal with JC signature.

JCR was amazingly helpful and they actually still have the exact bike I am replicating in storage (2005 1x Baja 1000) and have sent through very detailed photos of the bike so that I can use them as a reference. Given that they have just done Baja and the Dakar is coming up soon I thought that they were most helpful.

The guy here in Oz that I got the race muffler from had no idea what he had, so he wanted to use the stock muffler as it was quieter with his race headers. He even went and modified the headers to fit the stock muffler, it was an absolute crime in my mind but hey. Things are only worth as much as your glass of knowledge allows.

Thanks Bump, I am waiting to see how good the quality of the locally printed stickers will be before getting duplicates made, but assuming they are good I will get a few made and send one your way for sure ( I got the exact size scan too). I will also get a few of the logo decal sets made up (rear fender and side covers), just in case I ever change plastics again. No one seems to have them anymore, I'm guessing you were probably given the last set! They did have slightly different sponsor logos each year, especially on the rear fender.

I have seen the Hengeveld sticker in a few poor quality photos from a distance, would be awesome to get one if you can!

It was Joe Lloyd at JCR who has been helpful, but everyone I have contacted via email have been helpful, which is more than can be said about Pro Circuit. It is understandable though, email is never the best way to have passionate dialogue.

Thanks for the offer with the exhaust idea, I will certainly keep this in mind if the XR's only headers don't quite do it once I rebuild the bike. An interesting response I got from Pro Circuit, they reckon they never made a Ti system for the BRP at all..... There seems to be a lot of confusion about the race system and what it is made of.

Hmm, interesting. Mine definitely looks and feels like Ti.

Will look for the sticker over xmas break

I'll look for that sticker soon.

There are also two versions of the front fender sticker that says Suspension by XXX. I think the old one says Suspension by Bob Bell and is black with reverse type. I have the set on my bike, Diane gave my oldest daughter a set for her sticker collection and was hanging in her room until we moved and I'm not sure where it is now. Plus, I bought a set or two when Diane was selling the remaining sets on eBay. I assume what I have are the last version but I don't know and have never compared so they may be from different years. I think I have both versions of the suspension sticker.

Pro Circuit is a huge company for the dirt bike world and they probably have employees who never heard of the XR650R.

Just keep your eye on CL and if you find something you can have it shipped to me and I will repack it and ship it to you. If it is local I will try to go and retrieve it for you. I have a good friend in Poland I do that for and it has worked out well.

I'll PM you my email addy.

EBC 320 mm rotor

EBC 320mm rotor on a USD XR650R available for the stock forks as well.
I dont work for EBC but I like there Products
This would work well on heavy bikes set-up for adv riding

Will I need a different chain slider for a 43 tooth sprocket? It has what I believe is the original one, a white plastic unit with the rubber only on the bottom.

Has anyone experienced carburetor body/throtle valve wear? My newly rebuilt engine is acting up and the throtle valve has a bit of play inside the carburetor body. Everything is else is in specs...

Simptoms:
-hard to start
-revs itself out of control
-dies when I take off the choke
-rough idle

I changed the intake valves, valve springs, piston rings, valve seals, head gasket, tighten everything to the specified torques.... Everything is as the Haynes manual says.

sounds like a clogged pilot jet and idle adjustment.

General Jetting Question

So like I've got the XRR that's basically brand new (but sat for years in the corner of the garage) and right when I got it, I replaced the petcock and did the "Uncorking" including HRC intake boot, air cleaner snorkel and jetting and needle swaps. Also did the exhaust uncorking (eBay end cap & baffle removal) and smog pump stuff.

So, the bike starts reasonably fine and runs OK, but doesn't pull consistently at the top end. Also, if I let off briefly it has a bit of an abrupt chop before regaining throttle. The problem seemed exacerbated at higher altitude and basically liked it better initially off idle than higher-up on the revs. Oh, also, it was so bad at first I looked down to see I'd ridden the last 20 miles with the choke on to the first click . Of course the bike ran better with the choke off, but I expect more on the top - a lot more.

Any thoughts from you seasoned XRR Jetting Pros?

What jets? stock header? when you removed the snorkel did you remove the cap to its left? just like the snorkel hole. are you at sea level?

I am no Pro But I have played with it for some time I found the xr never ran right till I added the holes in the side cover but thats with the header.

I drank the kool aid yesterday! thats right the KTM basher got one. a new KTMADV 990r, honda you are just to slow I waited ten years the XR650r was just not good two up for my size. I will not be selling my xr650r dual sport but I think the xr600 and my second xr650r are going up for sale soon.

Sounds rich to me. Open up the air box cover or drop the main to a 165 or both if you don't ride at sea level much.

Might have fouled the plug running with the choke on too.
