Seems like a good price, at least compared to the local bike I'm looking to purchase, wish you were closer. :-)

Yes, what you heard about the XR250 exhaust insert is true.

If the main jet is currently a 145, with all the airbox, air filter and exhaust mods, it IS NOT jetted for sea level. If it was jetted properly for sea level it would have closer to a 160.

For the elevations of Taylor Park and Crested Butte, given the intake and exhaust mods, drop in a 150/50 combo, drop the needle to 2nd clip position from top.

Thanks Trailryder42. I am puzzled as to the 145 currently in the bike. I need to get this figured out!

Hello..Just tried to fit a cush drive hub (rear wheel) from an xr 400 m to my 05 xr 400 r it wouldn't fit - The wheel was about 10 mm to wide, looks like the xr 400 m swingarm is different to the 400 r. Interested to know if any one has a cush drive set up on an xr4 - I was keen to fit one but not sure if its worth the bother- I spoke to some one who had clocked 100,000 km on his xr400 as a commuter and no gearbox issues

Rode Commanche Point road to Stallion Springs on Thursday. Both mirrors went tango uniform from vibration and reefing on them without a wrench. They were junk anyways.



I never really gave much thought to mirrors until I dual sported it. A pair of cheapos solved the problem. It was a cool ride. I saw a cow elk with her newborn, road runners and various snakes.
Saturday I put on 200 miles trying to get to Sherman Peak and Kennedy Meadows (road still closed from Kernville side). I ended up on Cow Flat Road (off Hwy 178) on Breckenridge Mountain. Need to switch back to knobbies. Duro's suck in the sand.



I need some input on comfortable seats.





Reward at the end: Lamb kabobs at Petra's Mediterranean Diner in Tehachapi. If you're riding thru town it's worth the stop.

Guys, It's been a extended project, and my cheap XR has been getting increasingly expensive, but I've now replaced the countershaft and have most of the bottom end back together. When I went to reinstall the idler gear (on the countershaft end) I noticed that the gear bushing was slightly bow-tie shaped and when installed the idler gear had a fair bit of wobble. I've ordered a replacement bushing only as the gear inner appears in spec. Do you think that the bushing resulted in the broken countershaft, or the broken countershaft resulted in the bushing being worn and stretched out? The countershaft snapped just on the other side of the case from the gear. Also, the idler gear stopper arm may have been bent when the shaft snapped. Does anyone remember what the distance to the stopper arm was from the gear face should be? Does anything else keep this gear in place on the shaft?

Thanks

I don't know how anyone would be able to adjust the valves without these:

Very helpful and don't cost that much. R.

Just received and test fitted my Wolfman enduro tank bag and fender bag. Looks like quality stuff. Also sent the same tank bag to my brother for his birthday (DR400). Both bikes have Clark tanks.
