What did you do to your dirty bike today?

[ScottRNelson]

I put Rox bar risers on both bikes so that I can ride standing up without hunching over. I'll have to avoid going full lock to the right on the KTM or I'll eventually get a kink in the clutch cable. Not hard to avoid doing that. I had to bend the aluminum Cycra hand guards a bit to get it all to fit on my XR650L. A vice, a big hammer and a big wrench took care of that task.

Oh, and I set off a neighbor's car alarm with my new PowerCore 4 exhaust. Man, that Jeep Cherokee was honking for a long time.

100 hour tear down...


BR8EIX with 100h!


Low hours on packing, still spooged all to hell


(L) Compression at 0h, (R) Compression at 100h


Piston top


Piston exhaust side (that's reflection, not wear through the coating)

Clearance and ring gap were great.


Cylinder plating coming off an intake port edge. Shit.

[2strokeYardSale]

Rekluse screws backed out. Shit.


Screws kissed inside clutch cover

Measuring crank small end side play:

Right at the limit. Shit.


Fresh Shinko R505 Cheater


Shinko 546F with 100h. It was suggested OaklandF4i might want to pick up this take-off and continue to use it. Replaced with Shinko 216MX.


New closeout rear sprocket and hardware. Old hardware was loose!

New gearing will be 14/51, from 13/50, from stock 14/50. The Primary Drive X-ring chain seems quality but its master link clip fit is lame. My old (Regina) chain's master link clip disappeared on the last ride.

I've got a Shinko 546 and 505 ready to mount up. I've always been a Dunlop AT or Maxxis IT kinda guy, will see how I adapt to these Shinko cheaters..... Yeh, I'm a couple years behind you guys.

Top end looks pretty good for 100 hours, you have it dialed in.

What piston have you been using and how many hours on the cylinder and crank?

I need to pull my top end apart as its at 125 hours. I checked at 100 hours and the compression still hadn't dropped significantly since fresh when it was 185 psi.

You will love the 505 Cheater, it is good to fantastic, depending. The 546 is decent to good.

What piston have you been using

Wiseco. This is the first one with the coating and the first one I went all 100h without inspecting the rings. The previous Wiseco was uncoated, went 100h, but I think I changed the rings at 50h.

how many hours on the cylinder and crank?

Only 200 since I got a meter, I had to guess at the 50 before that.

My bike is fully assembled with the original piston (!?) and new rings as a temporary measure. I'm going to go start it soon and go for a break in ride.



Stupid defective master link clip with new chain:


Fortunately I bought a spare M link:

Its going to be awhile before I get to try them out as everything is closed. But looking forward to seeing what everyone is raving about.

I'm running the same piston. Will be tearing down some time very soon with all this quarantine time. May finish up the spare motor with the wide ratio tranny first.

Been trying to be real anal about filters to see if I can't get three top ends out of a cylinder (300+ hrs), will see. Was hoping for at least that or more from the current crank. At my pace, I think its more than reasonable to shoot for.

Bummer about the master clip. I've been running the same chain exclusively on all my bikes for 6-7 years. I've only destroyed one when I waited too long to give it some love after Baja and the salt did a number on it. Other wise I can get darn near 3k miles of use on them in the desert. On the YZ, I bet a couple hundred hours. I use their steel sprockets too. Heavy, but cheap and wear for ever.

Enjoy the break in ride!

Not everything.

There were two thumpers riding nearby when I stopped here for my second heat cycle cool-down. That was on Wednesday, so I guess more people are unemployed or furloughed.

Even though I have a real nice house to live in, I gotta get out once in a while. Went down to the Snake River again, way south of where I live. Wanted to see if it was any easier on an XR650L than on a 790R.

I went down the easier route, but came back out on the more difficult one. Still managed to get stuck once and kill the engine in the super rocky section. Didn't let the bike fall over, though and was able to continue on once I picked a better line. You have to stay about five moves ahead working your way through big uphill rocks and if you get behind you can end up trying to go over a big rock instead of around it.

This is the dirt road that gets you to the easier route down to the river.


There are farms down there, on the other side of the river.


Apparently roads to the farm houses too.

Since all the OHV parks closed I washed it and put SUMO wheels on it.....

[elemetal]

NICE! Looks even better wet. Are those the forks I gave you? Stock they were aluminum and chrome regulars; the black looks great with the street tires. Better just walk in to the local PoPo and hand them your license and get it over with : )

[ScottRNelson]

Okay, this was yesterday, but I was too tired when I got back to get the photos off of my phone and write something.

Crash tested the XR - again. It held up well and was way easier to pick up than the 790R. This was not all that difficult of an uphill section, but I hit a rock wrong, got off my line, stopped forward motion and dumped it. I didn't manage to get off while still standing like I usually do.

[2strokeYardSale]

Removed a link from the chain (after swapping back to 13T front sprocket mid-weekend) and installed a new chain guide.


RIP stock chain guide.


Note how the bent stock guide wore the bling off the new sprocket.

Installed new rear wheel collars/spacers. The right one was pretty worn and its dust cover was missing for some strange reason.

Removed the power valve linkage cover and un-fucked the gasket. I recently learned that gasket is self-adhesive with an adhesive backing you need to peel off. Motherfucker! Checked the torque on the cylinder nuts while I was there.

Tried to kludge a fix for my stripped brake pedal threads. Went to the hardware store and auto parts store and ended up ordering a thread fixer kit from RMATV.

Too bad for this SiP, haven't ridden it this way yet...
Yea the black really pops! Thank you on those forks, it needed those! (Almost hate the 'old' dirt rear rim )

Looking good D. Spoke up a black rear wheel to finish it.

I wish I had a skid plate that protected my pipe like yours. I have pushed the expansion chamber up into the right radiator twice recently turning it into a parallelogram I wrapped the chamber with a wide strap and pinned it to the ground with a car and lifted the bike with a forklift to bend it back. That is what I have done to my dirt bike lately.
