Nice. I remember when unless you could afford a Honda there were only 2 strokes.
I do remember always having oil on my hands, so, to the best of my ancient recollection,
.. .. you will have a great deal of trouble changing the oil on that bike.
I recall reading recently that one needs to be careful these days to choose the right oil for an older 2-stroke engine. Not sure if it was about ash content, or zinc content or whether to avoid vegetable or synthetic bases which weren't invented when the engine was built - or what.
Anyway, do some reading before you just assume that most expensive is best (in case it isn't - for you engine). And if the label on the oil says a higher mix ratio is okay because their oil is so great, while Yamaha said something different when they made it, stick with what Yamaha said - at least until you read independent verification that you can reduce the mix IF you buy the new fancy stuff.
One more thing, when you make your dramatic, first, triumphant slow ride into town to show off the new restoration, pick your direction carefully - so you will be riding against the wind
