Hey everyone this is my first post so I hope I am in the right area. I just recently acquired my TY80 that my Dad bought for my sister and I when we were kids. It has been well over 12 years since it has been touched so I don't really know where to begin to get it started again. I don't even know the proper mix of fuel/oil I would need to run it. I lack the knowledge and tools to tear into it. Thought about taking it to a dealer but don't want to fork out too much cash for something I possibly can do myself. Here are a couple pics of my bike. A little beat up from me wrecking a couple times but not too bad of shape. Not even sure of the year but from others I have seen similar, I am guessing 74-75. Any help is much appreciated and I look forward to meeting new people.

It looks good, I wouldn't be surprised if it just started with some fresh petrol! I'd use a semi-synthetic 2 stroke oil mixed at 50:1, so a 100ml of oil to 5L of petrol.

Great little Bikes ...

Clean carb , fuel tank , airfilter , Determine if it still has the yamalube oil injection hooked up ,(oiltank under seat/sidecover) if it's still there clean out the old stuff too . If no oil injection remains on it , mix up some 50:1 premix and give it a go ! Remember to fold up the right footpeg when trying to start it . Well worth the time and effort to get it going again

Here's a clip of the one I built for my youngest ...

As axulsuv said,clean the carb,fresh gearboxoil,fresh fuel(Synthetic Castol TTS 50:1)and a new front mundgard,and i will be shure the bike will fire up and start.It looks great.

Thanks for the input guys it will really help me a lot...I'm sure I will have many more questions. So today I just decided to mix up some fuel and see if I could get it started...Fired up in less than 7 kicks can you believe it! But I already ran into 1 problem. The accelerator handle will not twist/turn however you want to say it, so it just sits and idles. I didn't let it run it for very long but before I killed the engine, I pulled the clutch in and when I put it in 1st gear, it jumped forward and died before I even let the clutch out. Could the clutch possibly be shot? I know the cable is in need of replacement (torn a little bit but still functional) and I do have the replacement but once again lack the tools and knowledge. Need to see if I can find a Bentley manual or similar if they make them for this model maybe that will help a little because I am a complete noob starting fresh. I REALLY want to get the bike going myself so I don't have to pay for any maintenance. People in my area haven't been much help on some local forums and tell me my bike isn't worth the trouble but it has a lot of sentimental value and even though I'm 27, I know it can still be a fun little toy .

Well,your bike has been in the shed for ages,so you have do do a oil change.What happend with your clucht is normal for a bike have not ridden for years.The plates have been backed together with the old oil.Try first what i say,oilchange,and then ride the bike a while around changing the gears,using the clutch.Normaly it will be all okay after a few minutes.But also put a new throttle cable in an grease the thwistgrip,that will work wonders.

Ok so here come the noob questions lol....What position do I want the fuel dial (probably not the right name) or the choke in? Hypothetically speaking and assuming I got some maintenance done to get it in the ready to go state. The fuel dial has an O position in the center, and if turned left or right, has an S mark. The Choke can go in the down or up position but I know nothing of where either of these need to be. A friend of the family said he will help with some tools to get some work done but he knows as little as I do and I want to get it going by this weekend if at all possible. What else does a complete noob need to know to get the bike going? Sorry for my lack of knowledge I want to learn as much as I can anyway I can.

Haynes still makes a shop manual for the Ty80 , they come up on Ebay all the time , If memory serves its ty 50 ,80 ,125 and 175 all in one book , But all the information you need is in it . Well almost all of it ...

Glenn

And search for a original owners manual , The one that came with the TY80 is just about a complete shop manual for the bike , Any year model will do ,as the ty80 's changed very little over their whole production run . (why mess with a good thing !)
