NMZens, Let me first say, Welcome to ADV, that's a great way to start off on here Def interested in the conv parts and I sent you a PM. Let me know how I can return the favor!

Finally got my XRR back together.

I finally got my XRR back together after doing a complete tear down and rebuild. The engine got a new Piston and rings, Kibblewhite valves, Cam chain and sprockets, Hinson Clutch basket with a new clutch, and a Rickystator high output stator. I had all of the suspension rebuilt as well as new bearings everywhere. I had new wheels laced up by Woody's along with an oversize front rotor and a new rotor in the rear. I also added a seatconcepts seat. It should be ready for another 10 years of great service.

From This


to this

to this

To finally this


Now it just needs a little more fine tuning and it will be ready to go.

Thanks for the great product!

I forgot to mention that the best thing about this rack is that you can remove the side cover with the rack in place, no other on the market allows you to do that. One design feature of the XRR and most enduro type bikes is to be able to check and change the airfilter quickly. Nice!

Nice, seems like quite a few XRRs around Denver. We should have a Colorado XRR rendezvous.

Do it RideFreak. Looks looks like a great mod.

Do the sprockets need to be replaced along with the cam chain?

Any issues with reusing the stock piston?

The sprockets don't normally require replacement, as for the piston, you'll have to measure it and compare it to the spec, it's anyone's guess.

I need to do the CC also, I can feel it starting to get a little lazy as it stretches and the cam timing shifts a little.

Here's a couple pics from today's DS ride.

I probably could have gotten away with reusing my Cam Chain sprockets,but they are fairly inexpensive and with the amount of hours on my bike I replaced them as a set. Just like your drive chain and sprockets they will wear together and the best combination is to replace them as a set in my opinion. As said earlier you need to measure your piston to make the determination of whether or not to replace it.

Nice. Mine's probably getting this treatment next winter. I was going to do it this winter, but time and money said otherwise.

Just wanted to throw these pics up of my winter progress. I added the BD light, ATV high handlebars, new plate mount, speedometer from a 1984 xr250r, and the 4.3 gallon tank. A new skid plate is sitting in the house, need to throw it on one day. I notice the weight difference, but it's reasonable depending on the trail. Handlebars seem a bit high when sitting down, about right when standing up. The cables barely made it, another inch or two and I'd have needed longer throttle cables. I had to slide the compression release down a bit, but it's still reachable. The headlight is awesome, points down enough for street riding and I haven't been pulled over yet.

I'm thinking about maybe making the XRR more street friendly and dual sporting my XR250R for the harder trails. It's getting heavier as I go, and it's a handful on tight single track. The trail the pics were taken on was a bit much for me, I'm only 5'9'' and 150lbs. The only thing I would probably do is replace the Kenda Trackmaster II's with 606's or something when they wear down, which happens pretty often. I keep finding myself wanting to go on longer rides and exploring more, and the thought of the back tire melting off is always in my head when I get on the highway. I guess every bike is different for a different situation, and my local riding area is better suited for a lightweight 'flickable' bike. I'd like to get a WR250R, but don't really want to buy another bike or sell this one. The xr250r is a 1984 and not worth much, it'll just keep it for all that I'd be able to sell it for.

Ist,

piston, measuring - dunno if you know how that works? (No, I didn't check on the manual, it may tell you this also).
You need a calibrated micrometer of the correct size (100mm), and use the ratchet-knob only! Then measure the piston at various heights/places - and measure at each place/height twice: you need to measure in the direction/plane the crank rotates as well as 90 degrees off this, so 'across'. The piston 'rocks' in both TDC & BDC, and this causes most wear, especially so with the modern short-skirted pistons. The 'lands' (correct word?) between the piston rings are normally most affected, this in the rocking-direction of course, as measuring 'across' you may find either zero wear or a lot less. Only if the piston measures fine I'd reuse it, with new rings that is.
Maybe best to take it - with the specs - to someone who knows, and has got that equipment?
How's the cylinder - the nikasil still fine, no edges and/or irregularities? Don't try to do any honing (way too hard), if it's fine just use a mineral oil to run the lot in. If you really really want to use a small piece of very fine waterproof sandpaper, and then clean it like your like depends on it afterwards! Oh, rub it only at 45 degrees, a cross-pattern.

Here's some advice to run-in - and yes, anyone may have (has?) different/other opinion(s) on this, but here's mine.
Once ready to run start it, and let it idle until really warm, hot actually.
Switch off and let it cool down fully, eg overnight.
Repeat 3 times.
Then the 4th time (day?) go ride when warm, and nurse (low revs & very low load, this all at low speeds) it around the block a few times. Then, park again to cool down fully.
The next time do a bit more of everything, a bit further too, and of course let it cool down again.
Then take it for a ride, still easy does it. Better up the revs than the load, your last thing of running-in is fully loading the engine - at some 250 miles or thereabouts.
Then drop the oil & filter, put new stuff in and ride.
Yes, this whole scenario takes time and patience - but it's worth it I think. The various heat-cycles allow material to be taken off precisely there where it is needed, and also just by the correct small amounts rather than in (relationally) big lumps.

Here ya go...

Hey Ya'll,
I have my engine broken down with the cases split. I called the local STEALERSHIP and explained the such. I asked how much to just press out the crankshaft. I was quoted $70 - $80. I about laughed in the guys ear after hearing that. Today I went down to the base, retired military, and went to the auto hobby shop. About twelve minutes and four dollars later I walked out $66 better off. I stopped at cabelas and got some ammo for the sporting clays shoot this weekend with that money I saved. It sure does help to be mechanically inclined. Ride safe, Tony

Ticking noise.

Hi all. Im new to this forum and just purchased a 01' xr650r for a killer deal. Thing is it has been ridden hard and put away wet. the motor is all stock except for the removal of the emissions kit. The downer is that the motor is making a really loud ticking almost knocking noise. It starts and idles fine. I thought it would just be the valves. I checked them and one intake was a little tight and one exhaust was loose and the others were in spec. I tried to video it but you cant really hear the noise so well. http://s1157.photobucket.com/albums/p581/xr6fiftyrider/?action=view¤t=0416121553.mp4

Few questions:

1) Is that exhaust leak you can see or breathing on the lens?? Exhaust leaks can be very loud.

2) Ticking is hard to hear, but be careful. Lots of people adjust valves when decomp is engaged throwing out one exhaust valve.

3) Check slack on decomp cable to be sure it's not partially engaged. There should be LOTS of slack in the lever, and the engine mounted lever should return to resting position.

4) Seeing the side cases with that much wear makes me think there are lots of hours and miles on that engine. Might be time for some work.

5) Idle seems odd or is that you adjusting it? Does it rev up on its own and stumble off when chopping throttle?
