leakdown test.

[yamaha04]

ok guys im looking for some info, i made a leakdown tester useing the how to guide RNBrad had on here awhile ago and i just can find anything to use as plugs to plug my intake and exhaust. has anyone tried anything else out there to plug there port off that's air tight? post some pics give me some wacky ideas. i have spent about 3 hours grooming the hardware stores around here looking for something but just can find the perfect piece.

For the intake use a peice of round steel rod the right dia to fit in the carb boots and cut a couple of 3/4 slices off it. Drill thru and tap one to accept a barb fitting. The exhaust I use two expanding rubber plugs from the local hardware store.

Home Depot has 'em...the exhaust plugs.

Look over by where you'd buy the rubber chair leg thingies... They slide over the chair leg not to mar a wood floor, etc.

 

I think the Inside Diameter of the exhaust is roughly 45mm or so...if that helps.

Here is the one i made. The pipe is 1 1/4" schedule 40 sprinkler pipe from hope depot. It it tight in 35mm intakes. The exhaust plugs were the 1 1/2" from auto zone.

Well...I didn't want to say it, but....Firehead did pass them on to me when they got too small for him. So....he uses XXXXL But plugs....batteries not included.

On the exhaust side I use a short piece of radiator hose and clamped a freeze plug or soft plug in the end then clamped to the exhaust port.

That would still make you the guy using "used" butt plugs,,,,,,,,,,,,,I am not sure which is worse.

[bansheeman1988]

haha yup pretty much the same concept. i said screw buying a medical hand pump thing and just made one to work with the compressor with some fittings laying around my shop. your on the straight and narrow now, hope she holds!

The rubber ends on a stock bumper fit almost perfectly over the exhaust flanges... can use hose clamps to seal.
