1974 Ty80 Manual

Featured Replies

Hi all, just picked up a 1974 TY80 for my daughter, stal of a deal but it is all in pieces. Does anyone have an electronic version of the manual available? PM me if you do!

Never come across the TY80 manual online, someone does a CD you pay for and Haynes do a manual, ebay or amazon for a copy.

I've a Haynes, so if there is any info you need, let me know.

Closest I've found is for the 175, they aren't worlds apart, though there are differences, obviously!

John Cane has all the exploded diagrams on his site that may help

Thanks Goudrons, that gives me something to go at. So far it all looks pretty reasonable, just need to sigure out the wiring and this will help greatly. The only other real issue is that the kickstart hole is blanked off so I am assuming that either the shaft is snapped inside or the workings are just not there. Removing the side case this weekend to investigate before I source new parts. PRevious owner just used to bump it as his kids only rode it around a field.

Hmmmm.....one wire? I think there are some extras then as I have 4 coming from the mag. I think the only one I need to be concerned about is the BlackWhite one that goes to the coil, does that sound right?

Your advice is appreciated!

Yes, Black/White seems to be the wire to the coil.

Your stator must be off something else like a DT/TY50 or something, as it sounds like it has a generator coil in there as well.

What are the other wire colours, Yellow and Green?

Not that it really matters, as long as the ignition side works, I suppose you can run a A/C lighting system and use it to commute to work on!

I had one of these bikes as a kid and I loved it to bits, literally!

They'll take a YZ100 piston if it's a tired bore, perks it up a little.

Thanks to Goudrons and Charlyxty for responses, they have certainly put me on the right track. This is a very interesting time as my daughter (who the bike is for) is very interested in the workings and what I am doing in the garage....quality time together!

Anyway, based on your feedback I checked the wires last night and there are four coming from the stator, a black, a green, a yellow, and a green/red striped one. I assume the black is what I need to connect to the coil and then just cap the other 3.

with the side casings off the internals look in surprising good condition, no stator rust or damage at all so I am hoping that a kickstarter fix will get her up and running so I can attempt to part some of my trials wisdom onto my daughter!
