Wat u mean

It's as good now as it EVER will be. Whatever you do to it will be a trade-off to what it supposed to do.
Save your time and money on a bike thats worth the effort.

WR muffler on my XR, sounds good goes good, if youve got a CRF one try it out. If your looking for more power and torque it could be worth looking at an up size to a bigger chook chaser. ive got mine in work mode at the moment, kinda looks a little gay with the top box but its practible and fun getting around town to work, it only takes an hour to switch back to ADV mode.
like most bikes airbox jets and exhaust will pump her up a little even a 280 kit.
I think the XR250 is one of those bikes that do the business in stock form if ya want more then its time for an up size.
I also think stock XR mufflers are shite.

sift through this thread there should be lot of info http://advrider.com/forums/showthrea...ighlight=XR250

even in the XR250/400 forums on here theres some good info http://www.thumpertalk.com/forum/18-xr250400/

IF IT GOES GOOD, LEAVE IT ALONE ......otherwise you will fuck it.


If you are asking KB for advice ( there are only about 3 people on here who know their stuff) and going on the net, then you have no idea what you are doing.......so whatever you do, do, will turn to shit.


BUT....at least you will have an experience....

theres more than 3 on here and i know of a few qualified mechanics on here, but yeah if ya dont know what ya doing be weary cause it can turn to shite, if ya do start fildling make sure its reversable, dont forget that the XR's were top performing enduro's in there day so there made to perform so stock bikes are pretty dam good.
never heard much in the way of 250's getting modded except for the 280kit, most just upgrade to the 400 or the mighty 600
upgrading the muffler wont hurt it much unless it leans it right out which would eventually root it, it might change the performance weather positively or negatively more likely the negative with out jets and airbox to match. at least with the mufler you can swap it back if ya dont like it.
jump on my 600 when we hook up for a ride, simular discomforts just a shite load more torque.
one thing i like about the XR250 is its a fantastic trail bike, i rode one a few times over thompsons track and the gearings way better suited for that than the 600(with my ride skills anyway)

FJrider makes a Good point

Give it to me with half a tank of gas and I'll flip it, then I'll build it in to something extreme

[hayd3n]

keep it simple .
new plug
new oil /filter
replace/clean air filter
clean carburetor/s
adjust chain tension to spec
and set tyre pressures

Even the 250's respond well to a bit of "Gordon's Mod" tinkering.

I cleaned up the head on mine, matched up the intake ports with the manifold, skimmed the flywheel and it ran really, really well.

Although, to be fair, it was the superior 1979 model

fkn good show. when you say "cleaned up the head" are we talking a hone? or planing the faces?

good show. good show.

How do you hone a head I reckon he's saying he port matched it, like I did to my GN250/300

You take the head off, turn it upside down and go to town with the dremel in the combustion chamber.

I would have liked to do a bit of MotoMan style velocity porting (I like torque) but there wasn't enough room to start with.

The head is coming off the TT350 soon to do the cam chain & guides and I'll look at the ports on it at the same time.
