First off, thanks for the info on the forks. It is interesting to hear about the comparative differences between the different XR's and the USD conversion.

Moving on: some of you may remember that my XR was knocking badly at the start of March. I pulled it apart and found that a whole bunch of metal had blocked oil to the head, destroying the top end.
Since I didn't know where the metal came from, and there was some transmission problems (2nd/3rd like is commonly the case) I also had to split the bottom end.
Didn't bother replacing the rod since a lot of people said that 'the rods rarely go bad' and neither my machinist nor I could feel anly vertical play. Put a 100mm forger Wossner in, replaced the gears, cams, rockers, timing chain, oil seals.

Put it all back together, started it up and the prick of a thing knocked like crazy. Pulled it apart again (there goes $40 worth of gaskets) and got the machinist to press apart the crank just in case. Lo and behold the bottom was destroyed. Clearly this was where the metal came from original, and was the reason for burning it down the first time and now the second. Let my mistakes be a lesson (along with benno.h's similar occourence), that the big end can go in these XR's and in some cases it can't be even felt!
So put a new rod in, got the bore honed and polished up the 100mm Wossner, reground the valves to improve sealing, replaced the valve stem seals etc.

Started it up for the first time today...came to life on the second kick, with no knock! Quickly got on and went for a 50km ride, varying the throttle and riding the torque band and using a lot of engine braking. Hope this is an ok break in method!? Jeez it's got power now! the front constantly wants to lift in the first few gears, crazy fun.

However, I saw a good hill to engine brake down, got partway up and began to turn and promptly dropped the bike! This is my first time ever dropping a bike like that, I guess I just wasn't used to the height and down it went. Obviously this shouldnt matter as it is a dirt bike, however I had forgotten to reattach the right handgaurd and of course it went down on the right side with a lovely crunch, which was my brake lever snapping. Turns out it is very difficult to lift a bike up on a hill without a front brake since it just slides down the hill, even in gear (it was steep and slippery hill). I couldn't get back on it from the downhill side due to the height so had to do a walk of shame, half carrying it down the hill.

Then I had to start the bastard! Yes, normal routine for starting a dropped XR except the drop had bent the footpeg in so the kickstarter would get stuck under it each stroke. Very frustrating! Oh and then I had to ride back through the city with no front brake, but at least that meant I employed engine braking a lot.

So yeah, that's my story. Pics below.

Sorry to hear of your misadventure.

You couldn't have swung aboard using the footpeg from the downhill side, then clutch start it rolling downhill?

Hmm probably could've but didn't trust my balancing abilities. I do wish I had roll started it though, didn't even think of that!

So, I had a play with the XR resto project again today.
Got all the lights working as they should, bit of a hiccup with the headlight..
turns out that 6v globes don't like 12v....Who'd 'a thunk...go figure

Still got a bit to do, kill switch, horn, wiring tidy up, tyres, chain, sprockets....etc.

This is what it looked like when I picked it up.. (poor thing)



Anyway, here is an updated pic of what it looks like now..

Nice one mate!

So, not a machinist error after all eh?!

Finally brought home an 86 XR600. Oil leak help?? Pics.

I just picked my 1st XR600.....a 1986! I have searched & searched & finally she popped up for sale not too far away. Super excited & it's in wonderful shape.
I rode around the neighborhood & noticed an oil leak midway down the front of the fins. I see that on the left side of the motor, right there in the fins & above where the clutch cable is, that there are 3 small holes in the motor which seem to be leaking the oil? Below are the pics.
Does anyone know why these may be leaking & what the solution is??
When I spoke to the owner before buying, he said it had no leaks at all. He'd ridden it twice in 6 months. And there was no oil in the pickup after I brought it home, so it must have just started.

Those holes are NOT supposed to be there. The holes look like they are drilled into the cylinder hold down bolt passage way.

Pick up a FCR carb from a CRF 250 or 450. Most of them are 40mm which will work well on the XR600. You will need a NOSS MACHINE adapter and a XR650l carb to head insulator as it is needed to change the angle of the carb as the OE XR insulator will have the carb hitting the frame.
