that doesnt backfire or anything... btw, why didnt you just get a CRF 450 R???? Same horspower, and you can go up from there! plus, the XR's suspension SUCKS! ever heard of inverted forks???

I used my XR for commuting, supermoto track days, off roading, everything. I thrashed the crap out of it for 13,000 miles and with the exception of the clutch bearing and a seal, it was faultless. A CRF would have been though 4 total rebuilds by 13,000 miles and wouldn't have done what I needed it to do, i.e. get me to work with a smile without all the hassle of a new piston every 10 hours.

Nah, Vertemati, bad BAD move, thing exploded after a couple of hundred miles, I spent £900 on a rebuild then swapped it for a Montesa 315R. The

Vert exploded on the new owner within weeks. Poor oil supply to the bottom end on early Verts I guess.

Popping on a closed throttle is idle jet, didn't have a bigger one so left it. Most open pipe supermotos pop like buggery anyway.

Yep, it's an XR650R. Never had trouble myself with the buckles. Biggest mistake I made selling that bike, it rocked! 13,000 miles, trackdays, off roading, commuting. Ran it on Halfords Basic mineral oil, changed every 600 miles. Great bike.

Every bike will backfire on the dyno, proper jetting or not.

@CaptainCropper true and i know which one id rather be sitting on at 60mph :) the 450R would be revving its guts out

@hendrixjon your dumb

[eyeofth3b3hold3r]

@CaptainCropper beautifully stated, perfect bike for specific needs, the big red pig is my favorite bike for the money for life

[raremountainbear]

@hendrixjon Because CRF450's suck. XR650's, both R's and L's, are the shit.

Hace poco corri en una xr600 del año 88 y la verdad tan mal no quede, de echo el motor es inmortal y durisimo, claro las suspensiones han mejorado dramaticamente a la fecha....XR600 Rocks!!!!

[flozell87]

Fuckin noobs. Ever heard of fork seals wearing out on long endurance races because they are always in the dirt and sand? The whole world aint a groomed supercross track.

[foxwhore]

no, you are very wrong, they make that 'snapping sound' wich is actually popping becuase of backfire, (too much fuel wich means the bikes too RICH) he needs a smaller jet and needs to run it leaner. NOT richer.

Nitrodrums75 .... This is what you can do..and get super results...Have LA Sleave make it into a 710cc , then a pipe...K&N Filter...and finally a XR650 HRC Bullet Cam...Very reliable..You'll be on a different bike should put out i'd say 47 HP. You'll like it..I did this once before my XR650R.

Your 650L will cook !!!
