Leak down test on Honda cr250 motor for all 2 strokes fixed in minutes!

I will show and explain how to perform a leak down test on a 2 stroke motor. I fixed both of my cr250 engines within minutes with this technique.

Where do you get this kit? Thanks nice video, 1991 Honda CR250 acting like you said, probably crank seal i thought before watching this video.

Good information, building a 92 250. Waiting for cases to come back from Vapor blasting. Moly grease noted

[@motoblast3574]

Awesome! It’s probably a good idea to do this test right after the motor is assembled. We do vapor blasting as well! Thanks.

So u don't have to split case to do both side

[@florianjacob8365]

Do you have a link of this kit?

[@motoblast3574]

I don’t have a link, but just search leak down test kit on eBay with your model and a kit that is specific to your bike will pop right up.

What was the problem with the first motor ? I have a fully rebuilt motor on my blaster and I have no air leaks, great spark, 140psi compression and it just back fires when I try to start it.. I have play with the carburetor I’m running stock jets but still I can’t get it to run😭

[@motoblast3574]

140 compression might be low. I would look to see what it is supposed to be at stock. My cr250 is supposed to be 190 psi for a stock motor and my modded motor is 230psi

[@djantix1200]

Sounds like your timing might be off.
