Oil injection plug fail. =)

[dem0nk1d]

So about a month ago or so I bought a very used motor from one of our brothers on the island ÔÇÿVeedubÔÇÖ. After a few emails back and forth, I decided to send him over some money for him to find me a motor. As you guys may know finding a Af16e or Dio motor on the island is way easier to find, than one on the Main Land. After some searching he found be a pretty good motor. The motor itÔÇÖs self was defiantly in need of a rebuild, and was is desperate need of some loving.

The motor came with a SYM DD50 transmission 6:1 gearing, and Koso green flywheel cooling fan. He also told me one of the head bolt holes was stripped which is no big deal. IÔÇÖm thinking of installing head studs and jb welding them into the block, or doing it right and installing a Time-Sert ÔÇÿbetter than a heli-coilÔÇÖ. Also that the kid he got the motor from looked to have JB welded the oil injection hole. So with everything known about the engine I waited about 20 days or so for the engine to come. Man let me tell you 20 days is a lot. I think when the sent it out the found the biggest and buffest Hawaiian and set it Via Kayak or something. Sheesh! Well the motor finally came, and I started the dissemble.

So what was that JB weld plug? Did they fill the whole injection inlet tube? Lets see! =)

So silly me didn't take a picture of the oil injection plug but you'll get to see what was behind the gray filler, plugging the hole. Gray filler was silcon, and a US Quarter.

what so fail about that?I think that pretty smart that they found the quarter fits perfect in there. any thing to cover the hole up without oil/gas and air coming out.If no oil plug is available or injector,you have use what you got to make it work without destroying the engine.

I would think by having so much open volume behind the plug, you would loose a great deal of that needed crank case pressure. Genius yes, but ghetto fabulous for the win! I was always taught if you do something 1/2 a**ed then don't do it at all. Do it right the first time. Even if it takes a tad bit longer.

if it was the persons only means of transportation than I think that person had to do what they had to do to get there bike to work but yes you would loose case pressure but not enough to make the engine not run.I f your trying to achieve as much hp from the engine than case pressure is important.

[dem0nk1d]

I can't argue with you at all on that subject. Some times you have to do, what you have to do. I once fixed a broken gas pedal with a ziptie. Macgyver would have been proud!

[bakaracer]

I myself had to do macgyver rigging in my younger days to get me scoot running so I could go to work.It was my only means of trans to get around back then.

FYI,
7 pennies, stacked up, will perfectly plug your NQ50 bystarter port.

Resourceful -> YES

Ghetto -> YES

That is the coolest thing ever!

I am definatly going to do that.

The quarter does not fit on mine, that means your quarter must be modded.

I will post pics of my progress.

Now that you mention it the knurling is missing in the photos.

Google says the diameter of a quarter is 0.955 inches (24.26 mm), just a little big for the closest metric size. Possibly a Canadian quarter works w/ o modding - It is said to be 23.8mm dia. And if you have a British shilling around, it's said to be 24mm. Only makes cents a metric country would provide a good fit

I thought the Brits were the last Metric holdouts along with the Hew Hess and Hay. Even their currency isn't Metric. Pounds Sterling, shillings, farthings and Fathoms, what the heck's that about?

[dem0nk1d]

LMAO! What about blow by on your oil plug? =) Funny as *

Very funny, Jamz! However as K1d suggested, did you use any type of sealant or an O-Ring? If the "Money Plug" isn't airtight to begin with, you may otherwise have issues. That said, the copper and gold may act as an octane booster...

How dare you suggest that my money plug is less than air tight!

I will have you know that these quarters were milled on the finest cnc around these parts. However if your local shop is not up to the task of making one fit "air tight", a little bit of cherry laffy taffy between the pennies and the 4 quarters works well to prevent blow by.

If cherry is not available, grape works in a pinch.

You could also try a membrane composed of Fruit Roll-Ups. Works great for those base gaskets too.
