Another oil ratio question

Ok I know this is probably the most covered topic. And YES I DID try a few searches. Nothing is hitting the mark here.

So still building my bike, the manual suggests using Valvoline RACING two stroke oil. Regular valvoline two stroke oil as a second choice. I got that since two different auto parts stores didn't have anything called "racing." Curious though what the difference is?

The manual also states NEVER USE synthetic oil, that it will reduce the life of the motor. And again, my searches of these very forums came up with advice to USE synthetic oil. On this point, let the arguing begin. I need to hear from people who used either. Pros and cons.

Now my main questions... and this too has always been debatable. I'm going to follow the manual on this to the letter so not to void any warranty.
They say, 30.1 for the first few tanks of gas. (not considering how MUCH the tanks hold, kinda vague there. The standard kit tank is only about a half gal. My zeda frame holds 3.74L, nearly a gal. My last bike I bought from someone already built, he said break in is about 500 miles. And it had an odemeter. So how far exactly would "break in" be?
Then the instructions state to run at 20.1 from then on.

Now I have heard it's more like 16.1 and actually my first motorized bike I did just that and it ran fine for several thousand miles but again, for the sake of not voiding any warranty I will follow instructions given.

Main question again.... And understand, I am badly math challenged. HOW in blazes does one figure out what 20.1, 30.1 or 16.1 IS? Lets say one gal. Using a plain old measuring cup, how much oil would each of those be? I'll dedicate a cup to this, marking assorted mixes per gal forever. Then I'll be set.

I asked this at two auto parts stores and got blank looks at each. So I don't feel quite so stupid. If THEY don't know, I sure don't.

You don't have to do any math. An online conversion calculator will do it all. So you want to know how many oz of oil goes into one gallon of gas with a 20:1 ratio? All you got to do is google "gallon to oz". A conversion calculator will pop up. Just type in "1/20" in the gallon spot. And in the oz spot, it will say 6.4 oz. That's how many oz of oil go in 1 gallon of gas for 20:1 ratio.

Yea, after I posted this their chat gave me the ratio in Litres and ml at least. I can user a conversion thing now. Meanwhile they also shipped me the wrong petcock. Threads don't work with my bike. So another WEEK before the replacement comes. GRRRR.
THEN... I thought well I can at least see how to hook up my odometer. NOT! I ASKED THEM before I bought it if it would work on the bike frame I bought. They said "with modification." SWELL. I have NO CLUE how to get this to work.
So what I bought, This bike frame
and the zeda 100 motor. All from the same place. So WHY can't they know to match the right fuel valve to THEIR OWN FRAME? Or exactly how and even IF their odometer will work on THEIR OWN FRAME????


Agh, can you tell I hit my frustration limit today? Go find my post about wiring. Not a clue how to finish even that much.
Yea I'm done for today. Time for a beer.

BTW yeti I love your avitar. Sort of a wild thing going on there. lol.

:D Thanks. Yeah I hear you man. I got a new petcock too, threads also didn't match. Luckily I have a friend who was able to tap the threads of the gas tank to match, but still. I have no idea what gas tank threads they are supposed to match. Some exhaust pipes need to be bent to fit just about any frame. You need extra parts for stuff to work that the sellers don't tell you about. Its just dumb.
If you can't get your odometer working no matter how much you try, then I recommend getting a tachometer. It just has a wire that wraps around your spark plug wire, no electrical connections and its super easy to do. It tells you how many hours your engine ran total, it never resets, it just tells you how long from day one to ever on. It also gives you the current rpm your engine is running at which I love. Here's the link to the exact one I got. Its $22.49 on amazon

Well I really love this odometer/speedometer. Nice big round dial, analog, old school. Had them before, they are nice. (mounting brackets are crap, last one I modified that and put on a much more solid steal one. Even that wore out with all the vibration.) BUT I never had a bike without standard spokes before either. I'll figure something out, just not today. Fed up, irritated, aggravated, frustrated. Time to stop. play some dumb games, park on youtube. I know bikes are a non stop project. Just hit too many snags at one time here.

I DID get the brake hooked up today so I got that done. Swapped out that straight handlebar for a taller one, which of course meant my cables would be too short. Pulled off the rear brake and did the front, ordered another cable off ebay, came today so I got the back done. so there's that. Something accomplished today. Still most of the day was running in and out, on live chat, looking up youtube videos, only to find out my part is wrong. grrr. And wiring.... just had to stop. I'll work on that later.
I started a thread about the electrical issue. Here
