Hey guys! Im new just joined up.

Anywho I recently got this motorcycle from my friend here. And they didn't have any of the paper work for it anymore. And Im wondering what model it is and year?

Im in the process of cleaning it up. I was surprised I just put a new plug in it and some gas kicked it a couple of times and fired right up. And it set for about 20+ years I believe or longer.

I heard somthing that I could get the vin number off of it and get the year and model of it. But Im not sure how if some one could help me with it would be awesome!

Thanks in advance guys!

Edit:

Here's the pics

T991,

Welcome to the site!

First notice - this site is not image-friendly. So, you need to upload your pictures in another site, and then paste a link to it on this one.

We have a whole lot of folks that hang around, with troves of information. So, get the pictures to us to look at and we'll see what you've managed to acquire!

 

[Tricky991]

Hey thank you. Ok I uploaded the pictures to a different site and posted in my post again. Thank you for pointing that out to me.

And the seat seemed to have been recovered because one side of the red cover was coming off and I looked under and saw the original seat. Its black in color. And would anyone know of a great place to order parts for this motorcycle? Thanks again!

I will check the photos at home later today; they work fine on that computer.

Surely there is something on the bike with a manufacturer's label; an air filter, label under the seat, something?

 

[Tricky991]

Well i know for sure its a Yamaha. Since there logo is on the bike. Im looking for like what year is it and the make. (And on the note about the pics in the attached. I can see them when I edit the post so its not posting the right link or something.)

My dad used to have a Yamaha that looked like that. It was an 80cc two-stroke.

I don't know much more about it other than we have a picture snapped with my mom, dad, me and my three sisters all piled on it putting down our street in Los Angeles.

Try that these days!

Wow, lol yea i was surprise when i first took it out on my place to test it. Has alot of power for a little bike. The only thing wrong with it was that the gear shifter wouldn't shift.

Not inside the transmission but the mechanism out side and the clutch isn't working. But I can't get to the clutch since the screws that hold the housing on the motor are stuck in. And since there very light metal makes it harder lol.

Buy an Impact Driver. Harbor Freight, probably $10. That's the only way you're gonna get the screws out of the cases on these things. Japanese manufacturers made their case-screws from select Wisconsin Cheddar, until circa 1992.....

 

[Tricky991]

Alright will do. I have a Harbor Freight near here. Yea the screws are horrible. What would you recommend for a replacement screw?

And while I was working on the tires and brakes on it today. I thought I might check around for a number or something on the frame.
On the right side (left if your siting on the bike.) there is a number pressed into the frame.

Its letters and numbers only like 5 or 6. Could this be the vin number? If so how would I use that to find out what it is?

 

[pushrod]

T991, I'd root around the 'Net for a Yamaha ring-ding (2-stroke) specific forum.
They'd be much more apt to help.

 

[Buzglyd]

Try USA Two strokers.

They all like wacky old Yamaha stuff.

T991, look at this video:YouTube - 1966 Yamaha YJ2

If that isn't the same bike, it's a darn close relative!

I think that is! Sounds just like mine! Man I hope mine looks like that someday. Im heading over to that other forum right now to see if they could help me some more on it.

Thank you guys!

I happen to sell hardware, go to a local fastener specialty shop (NOT a hardware, auto parts or farm supply store) and what you likely need is a SHCS (socket head cap screw), or possbily a BHCS (button head cap screw) it will be metric (duh), and bring the origional screws with you, there are 3 different (2 more common) thread pitches available and having the right size screw with the wrong thread pitch is no better then trying to shove a drywall screw in there. A specialty shop should have a thread pitch gauge, if unavailable, put a nut (with known thread pitch) on the bolt to see how well it mates, therefore matching your pitch. Try to buy Camcar or Umbrako if available.
You will also have to see if they are fully or partially threaded, partial likely but make sure. All are likely M8 or M10 diamater, but the pitch & head are crutial for fit as well as the thread distance. Next issue is finish & coating, and they most commonly (aside of the motorcycle market) are black, some shops will have stainless steel, but you aren't likely to stumble across chrome heads unless you are wanting box quantities of each size. Good luck.

The sidecover screws are M6x1.0. That's fairly standard.

The Haorbor Freight impact driver ($7.99) is krap. The bits fractured the first time I used it, the retaining collar got misaligned and the entire thing stopped funtioning. Makes a nice ballast for holding down my RC plane wheels.

Get the "BikeMaster" brand driver. At $14.99, it's twice as expensive, but my last one lasted 20 years.

Huh. Times change. I've got one that's the "Made in Taiwan Harbor Freight Quality" my Dad bought from a dude sellin' tools out of the back of a rusty '68 Ford back alongside Hwy 37, circa '82 or so - not yet failed me.

"Harbor Freight" before there WAS a "Harbor Freight"........

Not sayin' they're worth two shytes now, though.

 

[pushrod]

Harbor Freight can be a 'crap-shoot.' Some stuff is not worth carrying home, while some items are pretty nice.

I've had really good luck with the 16-speed drill press and the 14" band saw (with extension). The original blade was crap, though.

A buddy uses their hand tools on his boat. He doesn't get upset about corrosion or other issues; he just tosses them and gets more.

Seems like there was a site (you just knew there would be, didn't you!?) that ranks HF stuff.

 

[Tricky991]

Thanks for all the info guys. I'll keep this all in mind. I don't have a local "fastener specialty shop". I'll see what I can do with that. Im hoping to have it fully restored or at least 3/4 restored by the end of this summer or sooner. Compared how fast I can get the things I need. But thanks again guys.
