    The crank rod for this bike was discontinued. I found the last one for sale in the U.S. and then had it professionally rebuilt which took more than 2 weeks. That's why this bike took so long to rebuild. Sorry for the long wait on this one! Hopefully you guys enjoy the video!

    As I said before, these little bikes are especially interesting because I had some good times with my son on one. Best decision I ever made. That was many years ago when parts were plentiful. Shame about your parts problems with this one. Thanks again for your time today and enjoy your weekend.

    Had a flashback when you turned into the drive at the end of the test ride coming off the road. I was about 11 at the time and did pretty much the same thing on my 1978 YZ 80 and lost the front end on the blacktop driveway with fresh sealer on it. Good lesson about knobbies on slick surfaces.

    3:00 I'd really recommend buying a seal puller. They are dirt cheap and you would have had that seal out in seconds without risking damage to the casing mating surfaces. They work good on fork seals too, not just in casings.

    I would like to have an old 80 yz but that last connecting rod and no cranks really puts me off. Being old it might last the rest of my days but would be fun. Looked like over 70 on the highway and more than 60 down the field, enough to bust your butt real good. It needed the rear suspension hardened up for your weight.

We ran a shop a long while back (90s through 00s) and I've had the pleasure of working on about 99% of the bikes you've done on your channel... and many others. Watching your vids brings back great memories.

    It is like you are riding your first 2 stroke. I've ridden a lot (75-100) of 2 stroke bikes both on and off road and the YZ80 was close to the most impressive for powerband. The Maico 490 was also a scary ass arm jerker on powerband but the Yamaha V4 RZV500R is just completely insane and wants to rip your hands off the hand grips.

    I had that exact bike as a kid. It sounds like your clutch is slipping, fix that up and it will pull harder. Also that exhaust leak where the pipe meets the head was a common problem, I can see yours leaking from the smoke when you were in the garage, that will take a little power away too. There were some copper crush gaskets that would seal that up for a while but they will eventually wear through, and I'm not sure where you would buy them these days. High temp sealant might work for a while.

    I always use gasket maker or case sealant on the intake gaskets on both sides on all 2 strokes, because with out it, it will leak cause it to run lean.. or leaner than you thought. If you leak down test the motor it will tell you if your intake, cases, cylinder to cases, and head are leaking/ not holding the pressure it needs to lube bottom of the crank case

  • @RealSuburbanCowboy
    @RealSuburbanCowboy 2 ปีที่แล้ว +9

    Get yourself a seal puller, makes that job MUCH easier. Also, it kills me that you don't clean up those parts before putting new parts in. I would be worried about dirt getting into the new parts. It is just so much nicer to work with clean parts. Put that case in the oven at 200 degrees for 10 minutes and that frozen bearing will fall into place.

    Also that bike is the same bike that was used in a movie called The Dirt Bike Kid released in 1985. Great childhood movie for me. You should check it out

    Just wanna say great rebuild and restoration. However, I would never recommend a Wiseco piston on a rebuild like this for a number of reasons but mostly because they're best suited for putting a handful of hours on them then rebuilding the top end. An OEM would actually be better for playing around on and not racing. Just my opinion and based on my experience.

    She's alive! Sounds good 👍 nice work. I used to ride with a buddy who had an 84 yz 125 looks the same just bigger obviously. I think it still sits. Needs a couple gears in tranny which he couldn't find

    You should have cleaned the 2T oil off that clutch pack and soaked the lot in 10W40..........

    I road one of these back in the 90s in France, for a full hour, for about 10 french francs for every 15 min..
    Next day someone stole that bike, so couldn't ride it anymore.

    Joe, I’m sure you have this question before. Why don’t you use a toaster oven to heat up your quesadillas that hold bearings? Application of bearings should go smoothly from here.
