Pic of the one I made I didnt take pics of the freeze plugs but this is the tester I made.
-
GrkGuy, looks real good, but just seems a bit complicated. Why didn't you just get the pressure tester from HB's website? Would have saved you all the trouble with fittings, soldering, etc. and shipping is $7 i believe.
I agree about the plugs though, they will be different depending on your setup so everyone should find what works best. I just took my carb and my exhaust flange to home depot and had plugs for both within 15 min.
-
REM, so I tried measuring the plug attachment and it didn't fit any of the threads I had on the measuring tool. Turns out spark plug threads are a bit off from regular bolt threads. I imagine this allows the spark plug to get a tighter seal the more you screw it in? All the attachments I needed came with the pressure gauge I got from Harbor Freight, and in the contents they just list it as 1/4”-18 (male) x 1/8” - 27 (female) and the part that screws into that is listed as 1/8”-27 (male) x 7/32” (barbed). Look at the picture on their website to get a better idea, i posted the link earlier.

ok I got all the stuff except for the air chuck.
15lb psi gauge $9 amazon
copper pipe local industrial plumber shop $19
air chuck cant be more than 3-4 bucks
i still need to cut the long pipe, i went a size bigger to help seal better, if you look at my old one you will see blak tape
i put on it to fit better.

i am gonna build another one that should cost $15 out of pvc. stay tuned.
all i need to do is get it solder up, i dont know how to do that, so gotta get my dads help.
-
ok i got the gauges and the reducer, now i need help.
i need a 3/4'' female sleeve with threads on the inside at 1/4''
then i can soder the sleeve in it and thread the psi gauge in that.
any idea what that part is called. guess it would be just like heli coil
but i am sure there is a name for it. i just dont know the name. so i need help.
-
i am only going to make the leak tester, you will need to find the plugs to seal your motor.
i am going to hit the plumbing store tomorrow.
-
Just get rubber freeze plugs.
-
I'd be down for to buy a copper one from you,,, but i would need a different exhaust cap since my pipe has a solid flange
-
man i had no luck today, harbor freight employees suck, they dont know anything... i went to home lowes to, and pep boys.
only parts i got was the plugs, i am gonna try and go to a industrial plumbing store monday, making it out of copper pipe.
plugs were under 4 bucks. lowes had a pretty nice one.
-
It was 15 bucks http://www.harborfreight.com/fuel-pump-and-vacuum-tester-93547.html?utm_referrer=http%3A%2F%2Fm.harborfreight.com%2Fcatalogsearch%2Fresult%3Fq%3Dvacuum%2Btester (http://www.harborfreight.com/fuel-pump-and-vacuum-tester-93547.html?utm_referrer=http%3A%2F%2Fm.harborfreight.com%2Fcatalogsearch%2Fresult%3Fq%3Dvacuum%2Btester)

how much was gauge up there, i got one about 45 min away, i am gonna go go up there today, i need to get some tire spoons from there.
-
That would be great! I appreciate it.
-
Rem, I bot a set of plastic T's from autozone, and the brass fitting for the spark plug hole came with the pressure tester kit. I will check the thread and diameter sizes when I get home and post them on here, pretty sure you can find it cheap on ebay.
Grk, I got my gauge from Harbor Freight and it's 0-10psi. If you don't have it in your area you could order it online, but I'm not sure how much they charge for shipping.
-
do you want a copper pipe one or pvc, i guess that will be the 2 you have to chose from.
guess i will price both of them out, i looked on line tho and did not see any low psi gauges at lowes.
i was looking for 0-15 lbs.
-
I will buy one from ya John!
-
i am gonna go to lowes this weekend and try to see how cheap, but not so cheap its junk. i can make them for.
i got a nice one now thats built from copper pipe, but i might try to build a few and sale them for the shipping cost. or maybe build a few to
loan out, you pay the shipping both ways and you can use it anytime you want. i might even be able to pay
shipping to you, well wifes work will pay for it. lol but just as long as i get it back in a week or 2. could save guys
a few bucks that just dont have the time or cash to spend on something they really dont need. but even tho you
own a 2 stroke you really do need one.
-
So I am getting the pieces together to make my own tester. I had the vacuum/pressure gauge in the tool box, the amazon blood pressure gauge with pump is $9.89 with free shipping so it is on the way here. I am looking at the fittings, did you just pick up a brass T and a fitting that will thread into the spark plug hole? Do you know what size that is off hand? I appreciate your insight to post this. It will be a very useful tool as I am pretty sure I have a leak in my '87 zilla , am currently putting my '91 lt250r back together, and needing one to chase the demons on a 2003 lt50! Thanks again.

Interesting, good to know.
-
Actually there shouldnt be much oil/ fuel mix in there. If there is, Your motor might be over fueled or a clutch side seal issue.... Im sure there's more to it if thats the case.
-
I only drain mine when I run outta oil for premix :))
-
How often do you guys let that drain out?
-
Thats where you drain the power valve chamber of oil and fuel build up.

This guy...

A picture is worth a thousand words!!
-
Reporting back, the tester worked great. Found a couple of leaks and took care of them.
There is a single bolt on the side of the case that leads into the crank case. It doesn't hold anything, it just plugs the hole... Anyone know what it's for??
-
I have about 33 $ in the one I built. Works well and really happy with it.
-
I was just looking at a MityVac yesterday for a new leak down. But now I'm thinking i might save a few dollars and build one. Thanks for the heads up on you set up.
-
looks pretty nice
-
Put this together to test the rebuild and thought I'd share. Haven't gotten to the point to actually use it but it should be perfect. Will update with results.
