I baught a 87 spree for $20 back in october. It has ben sitting outside for years and everything was froze up. It is a winter project right now, I freed up the motor put new rings and gascets in it and honed the cylender.
I have to free up the starter button yet, the kickstart is freed up now.
my qustion is how do i make sure that the oil injection is working right?
I took the tank off and cleand it, and took the 2 lines off and flushed them and the screen and blew air through them and put everything back together. I just want to make sure its going to work before i try and fire this thing up for the first time.

Just disconnect the oil line end that attaches to the carburetor. Start the bike up. If the pump is working you will see oil begin to drip out of that end. Its not going to come pouring out. It will drip out slowly. As long as you see oil moving through that line you know it is working. Make sure there are no air bubbles in the oil lines before you do this. Make sure you are using 2 stroke injector oil as well. If you see no oil moving within 30 seconds or so shut the motor down. You may have a problem than.

Its not necessary to add oil to the gas tank. When you fill your oil tank up make sure you can see a solid flow of oil in the line from the tank to the pump. You do not want to see air bubbles in the line. Squeeze the line if you have to until all air spaces are gone. You can also squirt some oil in the pump itself where the line attaches to the pump. Use a small squirt type oil can for this. You just want to make sure you have a solid flow of oil all the way from the tank to the pump. Like I said before if you see no oil flowing from the pump line to the carb when the bike is running then shut it off.

The only problem is that the oil lines are original black, and not the clear pastic so i cannot see oil going through at all?[/b]

Any good hardware store or automotive store should have clear plastic lines.

yeah, i will be getting some clear ones very soon. Im going to replace all the lines on one of my bikes with some new clear ones. I have been looking around, you can find them almost anywhere, there not to bad price wise at autozone[or similar places].

Ok i will get more clear line then i plan on going today to get clear line and replace all the fuel line and get a new fuel filter anyway. But what do i do about the one line that goes from the oil tank to the pump, thats the line that has a screan in it so that one is made to fit the screan? Should i just put clear line there anyway and not use the screan?[/b]

I believe you can just slip that boot over the clear hose and clamp it together. The oil strainer end may even be the same diameter as the inlet port for the pump. Its been a long time and I do not remember. Pull the strainer out and look for yourself to see what I am talking about.

Please, do not use clear vinyl oil, fuel vacuum line.
It's not made for oil and fuel.
It will harden and crack.
Use the semi transparent polymer line.
It's fuel resistant, stays flexible and you can see if you are having any fuel, oil vacuum related problems
I just sent some to Kenny_McCormic. Ask him what he thinks?

I just got done putting it on, looks great and cant wait for it to warm up outside so I can test it out. Thinner walls compared to the stock stuff, not sure on the sizes but the vac line is a tight press fit on the barbs and the fuel line pulls off fairly easy (lol cant even get the vac line off to measure) but I put the clamps that were on the stock vac line on the new fuel line and it holds great.
