Great! I would put a little ATF or Marvel mystery oil into each plug hole for now. It will coat it with oil, loosen the rings, and take care of any rust.

hi Frank,
The mystery continues. That looks like an 81H that has been painted maroon. Cues are: Front fairing. slotted rotors, saddle, Bags, rack, rear turn signals on a bar. short Special exhaust. rectangle foot rests.
That is a longlist of 81 parts for it to be a 78E
Check date of manufacture on the neck and confirm vin# is same on both.
Somewhere on here is a list to identify all the serial numbers.
Check TCI part number 4RO-

Can you get it inside as this warm spell will not last.

Frank, do the YAMAHA logos on the tank have two screws holding them on?
81 H 6.2 gallon (US) tank does not have screws...all other years do.
Is it time to welcome another Venturer back into the fold ?

Hi Frank

A mystery - cool!

I do remember that the serial number on the steering head ended in 00043x. It was all I could see with the fairing on, and haven't looked since.

I'll check on things tomorrow. Leafs vs Jets is on.

...and that IS an 81H(Venturer). BTW, no kick-start assembly NOR kick-starter with the 81H. You'll notice the kick-start hole on right side is plugged from factory.

Got to change back my signature?

The black ring-groove on the engine's alternator cover says '81, you should probably change the 'sig after you check the serial numbers, it could be a Frankenbike.

I put in some regular motor oil.

The problem with motor oil is that it will NOT free up rings, or take care of rust! ATF or MMO are your best friends at this point, IMHO. BTW, it DOES look like an '81. Check the engine number, and then see if the frame matches it when you can.

Good to know, thanks. Tomorrow.
