83 430 Rider Project

No apologies needed. The frame prefix is 565. It was a one year bike and also the only laydown 2 stroke Yamaha. They made I believe 2018 of them. They are the same year (1976) as the first 125 monoshock over here. They didn't sell like hotcakes. Rumor is they were the back up if the monoshock failed. Many were never sold and were probably crushed. There is a thread on the OZvmx forum about them. You folks in Australia have 5 of them that are known. You can tell by the gas tank which looks like a YZ but is a small amount bigger and made of steel. The motor is basically a YZ motor with a smaller carby and steel bore.

Thanx for the history lesson. I do think that I saw one in a dealership back in the day. But never even noticed the rear shocks.

Yep, the canisters came on the YZ400C. The desert guys around here took them off and put normal caps on them and plumbed them with a balance tube with a single schraeder valve. The only problem was when you blew a fork seal which was common in those days, the forks collapsed because they didn't have springs inside.

Back to the Husky stuff. I worked a little bit on the bike this past week. I as you will soon find out have a great sense of humor. I took the reed valve assembly apart and did some media blasting to it. I masked off the fiber reeds as there was nothing wrong with them. In my feeble mind while blasting in the cabinet the tape was blowing off the reeds. Why I didn't disassemble them totally is beyond me . Of course I peeled off the tape while I was blasting and took out the petals. So $50 I hadn't planned on spending down the tubes. Yep I'm a bright one. I have to order them up this week with some other stuff and I also cleaned up the air cleaner rubber mount that was...............you guessed it.............white. They came out good. Here's the pic.

Continuing on I stuffed the motor into the frame on Sunday evening and mounted the pipe. I forgot how much I really enjoy bikes with the swingarm pivot going through the motor. I came close to snapping on about the third try to line every thing up. Had an adult beverage and it finally went in using all sorts of blocking and prying devices. It wore me out. I even put the pipe on as a mock up to see how it all fit.

I really need some help here. I bought this chain tensioner off Evilbay and it says XC 500 on the part in sharpie ink. I am not sure exactly how this works. The arm with the roller is the same length one as I got from Ron's brother.

When I went to mock this up on the bike.............well from the pics you can tell something is not right. Where the chain tensioner needs to be the pivot axle or what ever you want to call it is way to long. I can make a spacer to take up the extra part of the axle showing or I can machine it down and re-thread it. What do you all think I should do?

I would take an old valve spring or inner spring with similar ID to the OD of the bolt, with 2 thin stainless washers,1 under the head of the bolt,1 between the spring and tube.As long as your not uncovering the grease groove or hole near the head of the bolt,if it has one.

Oh I forgot, thanks for the kind words. I like working on stuff.

I like working on stuff too, then riding and especially finding out it works!!

I thought about that and sealing the whole shebang with an oring for the grease... but I took 390Dave's advice and bought a compression spring to see how it works. Pic's in a few.

Actually the guy I bought it from had seen some of my Yamaha stuff on the interweb and wanted to buy the Husky back from me when I complete it.......or he wanted to buy my TC450 or my KTM200 or.......

Total nut job.

Pretty funny stuff. Good thing he wasn't around the bike very much....
Great work!

Mr Pilot,

Tank looks to land there monday.

Hey, hope ya don't mind but when i was gettin ready to shoot last coat of clear. A spidey got on it. I had two choices? Clear over it or redo it.

I chose to clear over it!

Just messin with you and will delete this!

Put you a piece of small nylon hose over both wire ends of your tensioner springs. Save swing arm paint once the spring goes in use. If not you can use shrink tubing.

I'm kinda likin it.

I did get the tensioner mounted. The spring I think will do the trick as suggested. Thank you.



I didn't get much done yesterday as I was working on Curnutts for a couple of customers. So this morning I got up late, since I don't have a job at the moment (gubment shutdown) and pulled the carb apart to see what was in store for me. It was a real mess inside. I don't know how the thing even ran. Luck I guess.



I got out my carb soaking stuff and put it in too soak for today and some of tomorrow. Pinesol or this more cheaper same thing works real well on carbs if you haven't tried it.



I spent a little while working on some spacers for the footpeg return spring so it won't wobble around. The ones that came on the bike were too small. I had to enlarge the bolt diameter a small amount as one side had wallowed out and was loose. I went with grade 8.



More to come.

Glad the spring worked out for you. Im on my way over to vatozone or pep boys for some burnt copper VHT,thankyou for the paint info.
