Hi everyone,
As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.
When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.
Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.
Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.
Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.
Thanks for your patience and support!

Hi Squid.. Congratulations on your Best of Show... Combat Wombat!! That bike of your is the Best I have seen and I've seen a plenty. Again Congratulations! Yes Squid, FINALLY changed the 5/6 and 4th on the main shaft. No pic at this time but after making yet another jig for observation, found those were badly damaged ...seems I wasn't in TUNE to the condition of their edges (or rotational axis)(was turning the crank backwards most of the time
) and that's why the 3/4 shift fork got a good bluing, in gear but jumping as power over came the edges as well, putting a lot of pressure and pressure builds heat on that fork. Seems when I was on a spending spree on another site I bought a box of Husky Trans Parts. I found a set of gears from a 76 250/360. That set had the needed gears. Both the gears were still in layout blue, as they had been machined to repair the tolerances. Thanks JAY(the name etched into them).Good thing they didn't sell at the meet!! And the trans movement into 1st and locking at the meet was my carelessness in aligning the pawl and ratchet on the shifter/step feeder. The pawl dropped and jammed the steep feeder so it would not return to shift again! That's my STORY, and I am sticking with it...until proven wrong!
I have a call to Forest Stahl to see if he can repair the damaged gears so I can use them in the other 450 motor I have. Got the tank out for pinstripes Then decals and clear tomorrow. Will take pics. Then I'm gonna ride the crap, outta it Fri and Sat. Also, It was very excellent to meet so many like minded and Interesting people at the Oily Pipes Show and Meet. Have Great Holiday and DO NOT RIDE like I do

You know, now that I think about it, the 3/4 shift fork was not holding at the solder joint (post 34) and I bought a replacement from Vintage Husky. So now it comes clear! The one that was in the bike when I got it was damaged from the 5/6 set bouncing off the 4th wheel and broke the solder joint! Life is hard.. But it's harder when you stupid. It took 7 times in and out of the bike and two jigs to figure that out. I knew I'd win.

Sounds like you got the problem figured out, that's good to hear. Mechanical mysteries can be frustrating to say the least.

We'll see if they hold this weekend when I whip it. Here's pics of the powder coated tank back with pin stripe, and homage to my cat. Powder was hard to feather so I left the edge. We'll see how it wears. Decals and clear today. Yeah Team!

Finally, the tank is done. Here's some pics. It's sleeping in the welding rod box overnight. We'll see what the temp is in the morning. I'm guessing about 108 f. A few flaws but a far cry from what I started with, and only about 100$. Still have put it on the bike and load up for the hills. I'll put a cheap tach/totalizer on it cause she's new. And I have to fix the window in the truck, electric will not roll down, nothing worse than no highway air. Oh yeah, a nice buck out front this morning, he has a twin running around with him. Hope they stay for the rut. I'm hungry now.

Tank looks real good for a $100. I take you did the powder yourself? Did you cure it in a garage oven or the wife's?
And the clear can't be powder or I would think the decals would look pretty funny about now. So what is the clear, urethane?

Within 5 deg. and looking good. Powdered at a factory we service, they use the orange for huge cable trays and it looks real close. this is a great clear, very forgiving, just coat every 15 min til empty.

Looks good in the sunlight. All loaded and headed out. It's the first cold snap, so I brought 2 sleeping bags and a comforter. Brrrrr. Going to ride her like I was 23.

Well I hope this doesn't mean your next post will be from a hospital bed.
Not so worried if you were talking about the Honda.

Back from the weekend and you'll be glad to know I still have 4th gear! I only rode her like I was 45, couldn't remember what 23 was like! Seems the timing is too far advanced as I came to a tight corner she backfired twice, I had the clutch pulled in and stopped. I was like wtf! I revved it and no signs of illness, so I let the clutch out and started going backwards? I killed the motor immediately. Now, I knew instantly what had happened, but couldn't believe it. I read about it here somewhere that the motor can run in reverse if the timing was too far advanced and it lumped over on kick, but I was moving forward and downshifting to first. So she must have gotten to the top of the stroke while in gear then popped the other direction as I slowed the engine. It only happened that one time so now and forever will be remembered as "That Weird Thing" that happened at the farm. Other than that, she needs the idle jet one size up and the needle clip down one. She's pretty lean on the bottom. I couldn't get her to instant rev on a downhill when set like the manual. More fiddling! Also got the output sprocket off the other wr450 I have, and was pleasantly surprised to find the trans in almost unused condition, all bearings look good and spin freely, the rotor end is sheared but I have another. The right side bearing is good also. will take some pics when I pill the clutch side and pull the crank for rebuilding. Hopefully it won't need much more than seals. Then I'll try to campaign it next year and leave the 0008 motor bagged for resale. Going to need some advice on that. Justintendo, that truck has moved innumerable motorcycles and coolers so we'll need a bigger page and Crash, don't let the 2002 xr650r fool you, I don't call it General Patton for nothing.

Sounds like you had a good time. That's was counts.
I know the xr650 is a heavy bike and takes more effort to ride in tight stuff like the woods but out here in the desert that bike can be a lot of fast fun.
When you got the top end together did you do a leak down test. Every engine I've rebuilt has had some sort of air leak when doing a bench top leak down from an intake gasket, base gasket, crank seal, or seal retainer. If timing was to far advanced I don't feel it would start easily on the first/second kick like in the vid in post #94. The problem may be leaking gasket, a worn slide, plugged carb circuit, or something like that.

My Cat Says AREAR!
Yeah Crash, he's a brute in the stuff out here. One hour is like four on this old carcass. I did leak test when I first put it together, but you make valid points so I'll do it again before I change the carb settings. It's been apart a lot so things may have changed since the second start video. But now how do I explain " That Weird Thing" that happened at the farm? I'll presume is was drumk. Anyway here's a couple of pics of the motor stand I made to find the 4th gear problem. The plexi looked good, but wasn't tight enough to observe the gears in action.
This one rotates when the front bolt is loose, so you can put it in a lot of positions. It's a bit problematic to put the motor on and off but it's nice for doing the building and crank insertion. Doing that on 2x4s was awful! That's the other 450 in there now, with a five speed. Everything looks spiffy in there to me.
