Say hello to my new friend

Got my thumper getting close to a good hard test ride soon.
Side panels are out at a friends for some number plate decals with a blue stipe like stock and tank decals being made and its ready.
I changed carb, got another from ebay that was complete. I had parts missing like the needle for the seat LOL, the shaft to hold the linkage the floats move was gone too but it ran. OMG Had no curved tube on the top of carb and so on or the correct cable so i got all that back to normal.

Looking very complete & tidy. Nice job sorting it out. Looks like fun.

Nice job, keep an eye on that H2O pump! I fought that issue on my 86 400 when new. JB weld would work for a while but the corrosion always came back even with careful grinding and cleaning prep. Husky finally 'Gave' alum. replacement cases. Apparently the orig. were Magnesium?
Maybe you knew that from your 400? I'm new here but sure there must be thread on that issue?

Back in 85 i found out. When my friend's new WR 400 started leaking after 3 months and he got a updated cover for free from Husky. It had aluminium in the water pump area and its bonded in with expoxy like the 86 covers.

Its beyond me why they would make/repeat such a bad mistake 2 years later..

Using up left over parts and keeping their fingers crossed?? Holding breath till the Italian deal went through?? My 86 and buddies 87 not alum bonded...both failed!

ah, much better!

NICE! Good work. Very cool bike, 86 400 XC.

"510 Braaap!" hahaha, yer a crazy mad person 86, ya are!

riding along the edge like that, geez!...you don't have to risk all to impress us, haha...what beautiful countryside, thanks for showing it.

Once again jousting with trees!...and no one else out there except Bigfoot.

and good job with your 510, I love your enthusiasm and energy, how you get it done and use it, an inspiration.

Nice video. Crazy view from that ledge. Hows the bike "feel"? Does it feel heavy?

Bike feels heavy only when the brakes are not good enough. Its moves so good with a little throttle its kinda deceiving. I notice its extra bulk when lifting the bike

Thats about what I though it would be like. Torque is fun!

Got the bike all sorted out, Found a new stock Husky piston, new timing chain and did the base and head gasket. Set the valves and made a cable and arm to work for a maunal decomp.





Got the correct hoses from Andy for the water pump.





short video, runs so darn nice now.
Very quiet motor too, love it.

Nice work, it does sound good! I bet it's fun to ride.
You gotta hit those big mud holes head on. Just kidding!

Very nice find! i'm hoping for an older Husky to do up one day. I am just not sure how expensive it'd be to restore a husky compared to say a Honda or Yamaha. I'd just like to restore something in general. Also i've noticed that the older huskys are pricey as hell here in Australia.

hows the temp issue? see anything that might have been contributing to that?

No more coolant coming out of the overflow hose.

I think the head gasket was resued and air was pushing out of the cylinder under W/O throttle.

Had a longer clear hose off the cap over the tank and then down the frame just to watch for it puking.
Did a few heat cycles on the new rings and after the third cool down i could rip through all gears non stop with only a inch of coolant up the hose. I never lost any over the bend on the tank, i could let off and watch it drop on the first spin like a temp gauge.

hopefully thats the end of that..sounds like something at least made a nice difference when you reassembled..

You have a magnesium clutch cover that is corroded as they do. The seal will leak because of this and repair is difficult.

Also I would pull the head off and check the barrel as it is likely magnesium also and will be well on its way to rotting out. I know as I have the same bike and have replaced the clutch cover with a later alloy one and am searching for a alloy barrel off the later model. They are fantastic bikes.

As a stop gap I run waterless coolant to reduce further corrosion of the magnesium.
