GT80 Yamaha Engine REBUILT and TOP Speed Run!

[@Wolfie66]

I had a GT80 when I was a kid! Had a blast on that bike.

[@kentuckyyankee]

They're pretty cool everyone in the family rides it

[@teslaedison6236]

Top speed run at the end is a nice touch. You show the work and the fruits of the labor. Good job

[@kentuckyyankee]

Thank you!

Hi, I'm from Nicaragua, Central America. In 1992 I bought a 2-stroke yamaha gt 80cc motorcycle, model 1988, I bought it from a neighbor for US$800 with an 8-month term but since I had an accident 2 times, I paid for it in 10 months hahaha. In 1995 I sold it and I regret it to this day because I lent that money plus US$200 to add US$1,000 and they didn't pay me, my father's cousin was my rat lawyer hahaha Until now when I see this video and hear that sound it came to me mind my cute little Yamaha GT 80cc two-stroke motorcycle. GOD BLESS YOU MUCH MORE.

[@kentuckyyankee]

Thanks for sharing 🙂

Try using PVC pipe to put seals in when you have a long shaft to go over. Cheap and it's soft so it will not damage anything,many sizes in quarter-inch increments so you should be able to find just about any size you need.

[@dominikphilipp4234]

I was waiting for this. Love these old enduros - great video!

[@kentuckyyankee]

Thank you I wanna do some more work to it and then get it on the road!

[@Chris.J.A.B]

Wow,! About to restore my exact same childhood bike for my kids. Very nice

[@kentuckyyankee]

Thanks! I am actually going to start working on this bike again soon so stay tuned!

[@du-rron874]

22:07 OMG you are a genius!!!! It simply does not get any better than this!!!

[@kentuckyyankee]

Thank you!

[@iconatlarge]

We have 2 of these including the red one we had since it was brand new in 1980. They are supposed to have a square rear light and the motors were silver. Nice job tho!

[@kentuckyyankee]

Thanks for the info, the engine did have some silver, I actually may paint it again, didn't know about the taillight either, I still have a long way to go!

[@nateball-ri9nb]

Jeremy Holmes. I just bought a red one with square light. Very cheap.

[@kimweigel543]

Sure love to hear about what happened to Marcella! Since I have one like her and can't imagine parting with it!

[@kentuckyyankee]

I sold Marcella, I would recommend a Z900RS to anyone, that was the best bike I've ever owned, just came time to move on.

[@melfrank8379]

The coils are the magneto and the generator coil., I have a GT 80, it does have the adjustment on top of the carb for the cable

[@camilosurinach9381]

Very good video , like the old enduros bikes from the 1970s, Camilo from Puerto Rico, thanks

[@kentuckyyankee]

I love them too! Thanks for watching

[@brockett]

That was fun. If you have pre-mix and the auto oiler is working you will decrease the fuel / air ratio so it will run weak and hot.

[@kentuckyyankee]

Thank you! More fun to come with this little bike!

[@Formerlywarmer]

This was my first bike new in 1975 I was 11

[@jackrutherford-1]

how's your compression? looked like that piston might've been just short of top of cylinder. Throttle braking is my trick too. Hit throttle and brakes together to keep gas flowing.

[@kentuckyyankee]

I haven't checked what the compression is, I know it is possible to get more compression out of this engine. The oil pump is now working properly so I am not as worried about seizing it anymore, thanks for all your help Noped Thursday!

[@jackrutherford-1]

@@kentuckyyankee that was a lot of work you did

[@kentuckyyankee]

@@jackrutherford-1 You do it all time!

[@yoyosk8r1]

Great vid. Just wondering where you ordered your top end rebuild kit? Can’t seem to find any anywhere.. Would an mx80 pistón and rings work with this engine ? Thnx in advance

[@kentuckyyankee]

Hard to find ordered one from the UK if I remember right

[@andrewsedlak7187]

Where did you order the piston and rings?

[@ShogunAutoworks]

I said early when u took off it will gain compression as the honing marks wear in and the rings seat and well....... 👍

[@kentuckyyankee]

I need to get back to work on this little bike. It's a good one!

[@bethevenden4607]

Noice!!!!!.Not a spelling error

[@kentuckyyankee]

😂😂 Thank you!

[@Sanesaint1]

I don't remember my handlebars being like that and I never had no lights

[@randysegundo2503]

For the carb, what are the jet settings you start with? In other words, as you screw them in, how many turns when backing out?

[@OldManMuskrat]

When I was 7 years old my gt80 would run 40 mph top end

[@EricDeKirkwood99]

I just bought one of these bikes for $150. I'm looking to restore it to rideable condition to get some basic mechanical skills which I am seriously lacking. Something tells me these videos are going to be super helpful for me! Where is a good place to get parts for these?

[@kentuckyyankee]

You are gonna love your bike they really are cool. Parts ...... ebay mostly for me

[@EricDeKirkwood99]

@@kentuckyyankee Thanks! Do you know where you got the allen bolts that you used to replace the stock screws that are all ocer this bike? My stock screws are seized and i'm going to have to drill them all out.

[@kentuckyyankee]

@@EricDeKirkwood99 I thought it was from ebay it has been quite sometime since I worked on this bike

[@dominic7690]

I love driving mine first bike I ever drove

[@kentuckyyankee]

They are cool, I like this bike!

[@killer_fly4202]

Where was you able to order your piston and rings from ? And what was the part number ?

[@aronmcguire7391]

I also need help with this!

[@masterpainter9899]

Where are you located? Do you repair bikes? I have a bike I need help with. I think I didn't tight my clutch good and now my bike won't turn on and when it did the first time I put it in to 1st gear and right away it turned off and gave a hard as hell shift.

[@Sanesaint1]

In excellent condition Google said they are worth $3,335 now 2023

[@Sanesaint1]

seventy-two I don't remember but it was only four hundred bucks brand new

[@leviniswander9927]

Where did you get all your parts we r doing a 79 Gt 80

[@kentuckyyankee]

Mostly Ebay

[@davidaldrich3488]

give it to the little guy

[@kentuckyyankee]

He will be on it soon! Let him have it?? Idk 😂😂

[@gambini_modding]

bottom ring isn´t thicker, it´s just flat, while the top ring is conic, that´s why the bottom one doesn´t fit in the top groove.

[@Sanesaint1]

Google says they went 56 mph I don't remember going that fast I think they're about 45 brand new

[@TRKGL1800]

Please build a motocross track so we can see you do jumps

[@kentuckyyankee]

This can be arranged, and actually I have been thinking about it, but I'm too old to ride like that, my boys will have to run the track.

[@krismartin5377]

It's called a stator

[@TranslateToEnglish]

Ok which is it? You know for a fact or you're pretty sure?

[@kentuckyyankee]

Both....???......😐.......😂😂
