The XR250R Thread...

fire roads in Mammoth proved that she's at least 60 lbs heavier than my
79 KLX250. Felt more like 100+. What is the proper procedure for adjusting
the carbs? Two carbs per cylinder does seem a bit excessive. The "Trail Winner"
tires were definitely not "winners" on those silty hills.

I'd try to get XR250R suspention,make the swap and it'll feel like a new bike!
Then maybe a gas tank swap.Get rid of the metal and get a good plastic one,either a XR250R stocker,or a after market.Then just get rid of the things you don't need to lite'n it up.Like,pass foot pegs,reflecters,etc.
The way i understand it,one carb is for the idle sercuit,and the other is for the mid,and top.If it kick starts easy and its not doing anything major thru the range,i wouldn't mess with them.Just blow some carb cleaner thru them and alittle fuel additive for a couple of tanks.Then get a good air cleaner and makesure the airbox is clean,and isn't block off by anything.
Have you gone thru all the fluids and greased all the fit'ns??
Tires,well what are ya look'n to do?Trail only 50/50,etc??
Tires are cheap enough,figure out what kind of ride'n you'll be doing and get a set with new tubes.
There was a guy in the fleamarket sell'n 2 XR350R's for like $200!!!!!!!
I'd try to hunt them down and atleast switch the suspentions.You could get alot from them.Tires,wheels,brakes,airboxs,pipes,gas tanks,etc.That would be the first place i started!I don't remeber if he had them in parts or bikes,but if you search the thread they should pop up.If there close enough that would answer all your issues.
Good luck

Thanks awm. The bike is in excellent shape, the rider is not. I'll definitely
be looking for the XR stuff. As far as dirt/street use, I would guesstimate
something more like 60/40 or maybe even higher since the streets in SoCal
are not really small bike friendly.

A 60/40 tire,,,,,,I like the IRC GP-1.But i ride hard pack dirt with alot of rocks.You out west might want more of a knob,that is if ya got the sand i think ya do.
The IRC GP-1 sucks in the mud!!!!! But other then that its a great tire.On my bigger bikes i get 4000-4500 out of a rear,and 8-9000 miles out of a front.I stay on top of my pressure.
I run dirt only tires on my XRR,IRC 35's,and 38's.
When the going gets ruff on my DS bikes,i really like the Dunlop 606's.Outstanding tire for the dirt,decent on the road,but they don't last long,2500-3000 miles on a rear,and 5000 on a front,depending on how much pavement i ride.
Basicly,don't cheap out on tires,your only on two wheels.And find out what works for your kind of ride'n.Maybe some other inmate from your area can chime in and give ya a better idea.But the best way is buy,mount,ride replace.Its more fun find'n out by trial and era.

I was curious what is that IRS tyre couse heard about it but never saw it. I was really surprise that I'm not just heard but even used such a tyre but on our side of ocean its name KENDA. I had it on my previous bike. Try to find a difference


More or less on the asphalt and solid terrain, and bad on mud and sand.


Now I have MT-21 front and Metzeler Karoo rear. 70off/30on road. Like it on the sand a lot. MT-21 for asphalt and speed more then 65-70 mph on light bike like XR250 is unstable.

The Kenda 270 is a cheap copy of the IRC GP-1.
Theres a big difference in quality.
The Kendas are all over the place on the pavement.The IRC's are top notch in the corners,and great on hard pack,gravel,rock,fire roads etc.There death in the mud!

Thanks. Good to know that. We didn't have a IRC over here any way .

Sorry to butt in, but do you guys know if there is an XR200R thread? You guys are the lowest XR thread I could find. Thanks!

[AWM]

The Lowest!!??

I don't know if i should be proud or offened!
I don't know of a XR200 thread,and theres a big difference between the XR250R and the XR200R.
The XR200 is closer to a XR100.

Ok, guys, I'm getting to the point where I'm about ready to start my XR (see link below) after a full rebuild of the motor and am wondering if there are any tricks to get the oil flowing through the lines before starting it?

Also, any other suggestions will be appreciated!

Here's my recent XR250R project:

Hey Motojunky, I just read your thread and was wondering if you had
anything left from your parts bike? I'm in the process of XRizing my
XL and need suspension and an oil cooler. PM me.

[Olas]

Hey guys, i'm almost finished with my rebuild...it started like this:





and turned into this:







All it needs now is the suspension to be reworked. It runs good and strong but I do have some clutch chatter going on. Anyone experience this with their 250s? What could cause this? It is the original clutch I believe so it may be time for a new one.

[AWM]

Clutch noise could be alot of things.
Better take the cover off and give it a good look before ya ride her again.You just put alot of work in her,loose clutch parts bounce'n around in there would suck!!!!
I'd check to see if the basket is loose,might be time for a new one.Was it slip'n at all?Sometimes the steel plates wear out and make noise,but you'd notice the slip'n.
Whorse case,,,,,,out put shaft,,,,, .
I see from the pics,its not your only bike,so atleast theres no down time.
Pull cover and check,let us know what you find.

[Olas]

Yeah, I had a look in there after a short break in of five miles or so... Nothing out of the ordinary. The clutch basket has a tiny bit of play on the shaft but I believe that's just the bushing. The friction plates did have a bit of play inside the basket - as in forward and backwards play, only as much as 1/16" though. I did the screwdriver to the ear thing to the entire motor and the sound is definitely coming from the clutch. Pulling in the clutch doesn't make a difference, it did quiet down after a few miles though.

I have a spare clutch basket, though it is used, that i'm going to test out and see if that quiets it down. I really don't think it's the output shaft or bearings since I inspected everything and replaced all the bearings when I was in there...The clutch and clutch basket were not though. Hope it's as simple as a new bushing or clutch basket though...

By the way, the chatter comes and goes - it's not there all the time, it's random as far as I can tell.

Thanks for your suggestions! Keep 'em coming...

Hello All, I have had these bikes since the XL days. They are my favorite Enduro's. I am finishing up ( Yeah right ) a 88 XR 250 R. Started from a bare frame. Will send Pics if I can figure out how to, 51 year old computer dinosaur not to good at this stuff. Anyhow glad that there are more like me out there. 250's Rule. Tried to send pics but it says that they are to big. Will try again later.
