I hear that a lot but it just hasn't been the case with mine. No bogging and it isn't hard to start. Two kicks max, hot or cold. I think people who have problems starting an XR with the stock carbie after a tip over aren't familiar with the "clearing" procedure.

I think I may have mentioned this in an earlier post, but I think you'll find tuning your carb easier if you disconnect the pump. I also like to mark the throttle grip with a pen to indicate 1/4, 1/2, 3/4, and WOT. It's a silly little gimmick but it helps.
How does it run up in the Mountains, with jetting set a sea level?

The stock carb is great for starting ,it's great at WFO.
But in stutters and when you smash the throttle it's crap.
We might not ride it the same dude,i absolutely punish mine and the stocker just ain't up to it.

Well I am and ex motor crosser, hare scrambers, any race I could find when not over seas, working in oil field. I should have died several times coming up short on a 90 ft triple, bouncing of a tree WFO on an xr400, but any way the TM40 set at sea level jetting how does it work at altitude (2000ft to 4000 ft)

Doscervasas, Sorry I didn't see your post about the TM40 at altitude. I was with the owner of the TM40 equipt BRP on a ride up to the Gold country in the Sierra mountains. The highest we got (after starting at sea level) was about 5500 feet and the carb worked flawlessly. I think the TM40 is an all around good performer, it is a little fussy to tune though. But you could say that about most carbs.

With the stock carb the bike is a pain .

Someone above mentioned that they had better luck with the stock carb.

I just threw in my .02 that I was also happy with a stock carb.

Also, I promise you this, mine has zero bog.

EVERYONE who's ever riden my bike gets off and says "that bike does what ever

you tell it to do RIGHT NOW!"

I've ridden another XR that had the bog. I guess I'm just special or lucky.




no, this has nothing to do with the bog, but I like it.

Ay caramba!



These XR carburetor threads have succeeded in becoming as screwy as the great tire and oil threads of the past.

Just sayin'....

That is sweeeet, that is a lot of altitude to still run well. If you can find the jetting that you are running, I would like to have them. I changed to XR's only header and pipe, I bought there jetting, and I had hell with that, main jet way to rich, stayed with stock main.

Will the CR 500, still straighten you arm out? The last one I had road, I was riding a wheelie, hit third, and the beast jumped up in the air like it had a rocket under the rear fender, with me on my back.

Sure it runs great with a stock carb,i got mine to not bog as well with a set of PC pipe vents.
I never realised how bad the stocker was till i swapped it out.
