Wanted to share my latest project. I've still got a few things to finish up (new rims and some work cleaning up the fork tubes). This was a special bike to me as I got a brand new 87 YZ 80 for Christmas in 4th grade and started racing that spring.

I was given this bike a few years ago and it was about ready to go to the dump. I thought it would be a cool project for my stepson to help work on and learn about using few tools. When it was completed he'd have a bike to ride when he outgrows his 65 and I'd have a replica of my first race bike. It was amazing the amount of cheap nos parts I was able to find on ebay.

The white tanks are a challenge and after weeks of sanding and trying every trick I gave up. New tanks are available but I really wanted to keep costs down.

Where did you get the seatcover and front brakeline? What kind of pegs are those? Excellent job on the build!

Thank you! I'll add some more pictures soon. Last week I used jb weld to fill all the deep cuts in the fork tubes and then sanded and painted. I'm lacing up gold rims this weekend.

I tried to keep the cost down. The brake line was faded brown and ugly. I got some white electrical shrink tube and covered it. There has been a nos brake hose on ebay but they wanted over 100 bucks for it.

The seat cover and pegs came from eBay. There is a company in Thailand making seat covers for 35 bucks with free shipping. I've got 3 of them so far for different projects and have been very satisfied.

Nice job on the resto. My first 80 was also an 87 YZ80, albeit a 1 year old one that was already trashed so we got it for like $300. I was still riding a YZ60 at the time, actually.

Now you just need to send the motor off to Barr's Competition. I know they did a bunch of YZ80s like this one back in the day, including Colin Edwards' and maybe even Damon Bradshaw

What do you do Pete to brighten up the White tanks. I'm currently working on that part of my 1985 YZ 125 . Thanks

the tank on this bike is very good ill just sand it with fine grit paper till i get to 1500 grit then ill polish it, but i usually buy new tanks, and they are available for this yz 80 so ill probably be unhappy with how this one comes out and get a new one, this is an unrestored bike i havent touched it yet, ill do a thread in june sometime when i start on it

New tanks are available. Yamaha showed 2 or 3 in stock last year. Clarke also makes one. I just couldn't justify $300 on a tank for a bike that was free and going to be a rider. The stock tank was busted up. I got an eBay tank for $25 that was totally turd brown but no cracks. I sanded and sanded and did the hydrogen peroxide trick several times and it's way better but still way off color. I gave up. I needed to move on to other projects and get this thing together. I figure I can always pull the tank off and keep working on it. I got my new 87 yz at the end of 88 and rode it 2 seasons. By 1990 my tank was turning yellow anyway

This bike came with the newer dg crude silencer and a completely junk stock pipe that I tossed. I bought an original 84 dg pipe off eBay for $30. The 84-86 pipes fit but are a different shape.

Then I found out that the 84 dg pipe is about 4" too short from meeting up with the 87-92 silencer. If anyone is interested in this pipe or can help me find a proper 87-92 exhaust let me know. I'd really love to find an old yzr/pro circuit.
