I purchased a 56 trailblazer 700 a year ago and I am working on getting it fixed up. It was sitting in a barn for 40 years and needs an overhaul. I bought an old parts manual and repair manual, but it doesn’t say what oil, transmission fluid, fuel it takes. If anyone knows where I can find that info or knows what it takes, that would awesome. First restore and I’m learning as I go. Any advice would be appreciated

Pretty much everything you'll need is found here:

Here's the link to the Hitchcock's online parts book for the 1956 700cc Super Meteor, but the Trailblazer could have used an earlier engine:

Here's the link to the Hitchcock's downloadable manual for the Trailblazer:

Download the manual, peruse it, make up a needed parts list, post some pics of your bike here. Lots of folks here with "twin" chops. We need to see what you are working with and get an idea of your experience level. Help us help you.

You can't really rely on the manual entirely today as the lubricants they had then were much different from what we have available today. Originally they called for straight 40 in average conditions, 50 in temps above 90F and 30 in cold weather.

IMO, these like a thicker oil, such as 20w-50 (straight 50 can be difficult to find). Equally important is to find oil with a higher zinc content. "Racing" oil usually does (I run Valvoline in mine) or diesel oil. Note that these bikes have a dipstick with a wide range of capacity between 'full' and 'add'. Keep the level in the middle, not filled to the top line. Too much oil and it will start forcing it out wherever it can.

Primary side, most feel that Type F automatic transmission fluid works the best. What is nice about using ATF is it is red, so if you have a leak there it is easy to determine what part of the bike is pissing on your floor!

Gearbox is same as engine, 40w preferred. There is some belief that the gearbox just takes grease, because that's how they do it in India, but that is incorrect. A combination of grease and oil that makes a 'slurry' also seems to be acceptable.
