Thanks. Hopefully it helped you out!

[@LouisGiliberto]

Thanks for this video. I'm trying to figure out a problem on my Ural and plan to do a compression test. This made it really clear how to do it! Any plans on doing a video for a leakdown test?

[@nickbuchananracing]

Youre welcome, glad it helped. No plans for leak down test video in the NEAR future. Maybe someday
Rocky mountain atv is a channel that has a decent leak down test videoi think

[@Jose-kc9gh]

When doing cylinder #1 do I leave the spark plug on cylinder #2 obviously with the boot off the spark plug so there is no spark

[@nickbuchananracing]

You should puĺl all the plugs out at once. That way there is no compression in the other cylinders that arent being tested, this will save your battery/starter from working too hard since youre only building pressure in the cylinder thats being tested. Thats always how ive done it.
