Old 1977 Blog

1977 used to have a decent blog, but it looks like it's offline now. There's a specific article I referenced years ago about Puch Polinis, oils, seizure, etc.

It was found here: https://www.1977mopeds.com/blog/2009/03/02/why-do-puch-polinis-seize/

Anyone know of an archived copy? I emailed 77 to ask, but no dice so far.

'77 is experiencing minor delays at the present.

This guy mentions that article in the oil section. Dunno if it contains the information you seek.

Haven't had any luck with the Wayback machine. And yeah, it seems like the crux of the discussion is the same that's mentioned in the blog post there: that synthetic burns hotter and therefore the recommend a lower ratio if you're using it.

I remember that the 77 blog had a bunch of seized cylinders and it was comparing the points of failure with the ratios and oils they were running. I liked that.

Re: Old 1977 Blog

yeah not to dismiss any of what those guys were looking at back in the day but there is a lot of knowledge and understanding (and parts) available now that we didn't have back then.

if you want to start a post in performance tuning about some of those topics, i'll bet it would be a good conversation.

Re: Old 1977 Blog

Good idea. My Polini build is coming back from the dead, so as it moves along, I will probably do just that.
