That balloon tester was a stroke of genius Ryan. I love it. 👍

Well done and I must say: very smart diagnostic method!!! No need to buy expensive tools when you have a balloon laying around 😁 I guess the compression is a bit on the lower side, but it is not terrible. A tip for you: Add a tiny squirt of engine oil into the cylinders and move the engine back and forth and sideways to get the oil in between of the cylinder wall and the piston. Then do a new compression test. If it reads better values it indicates compression loss because of worn cylinder, piston or rings. If it reads the same values, the problem is related to the top.

great video Ryan, very modest, honest and extremely helpful to me trying to get compression to remedy one very low compression on one cylinder of my 250 G5 thanks

Awesome idea on the leak down side, it may be a bodge idea tool but if it does what you need then all is good. The compression will come up a bit once oil has flowed around, dry rings never seal properly. To check just squirt a bit of oil down the plug holes and re test

Mate your determination and patience is outstanding - many would have given up before now. The detailed videography and description of your thought process has truly been inspirational. I am nearly completed on my superdream rebuild and expect to encounter some issues ahead when I get the bike running so I can refer to your logical approach so thanks for sharing.

Nice trick with the balloon and water👍

Hi, let me just say I really like what you doing and how you solve problems, I think us home mechanics can learn from your channel. Cheers Phil

Great video Ryan , just binge watching your series and loving it. Thanks 👍😊

Certainly teaching me a thing or too , getting there now 👍

well done orsome

Glad to see you found the issue, we've all made silly mistakes and forgot stuff Haha. That's why I triple check everything to avoid finding something later on and swearing lots Haha.

Nice work Ryan. Your well on the way now mate. You look as your starting to enjoy it more too. Excellent work 👍💪

Cracking video and loved the way you got round your problems

Well done Ryan! You got there.

Well done, that's got to be the most unorthodox leak down test I've seen but it did the job. For future if you can make something with a plug thread on one end and a schrader valve on the other you can use a bicycle pump to pressurise the cylinder.There is enough compression to start the engine and you may find it increases once hot and its been run a while. Good luck with the electrics.

thank you

well done that man! love it when an idea works out. I was then thinking, so lets start it on the bench next but then, outta time, another video over - roll on next video.

Would this be a common cause for compression loss on most bikes? According to my mechanic, my enfield has critically low compression, but he reckons he can't fix it because it's requiring a full engine rebuild. A fix like this seems like something I could learn to do myself though, and I'd love to have a go at it.

Hey mate, just a question. My bike, cbr 600 rr 2004, is lately stalling in neutral at stops even clutched in and also while riding will lose power for a second or two or will jerk forward sometimes as I deccelerate. Do you have any idea what the issue might be? Thanks

Compression is still very low, let's see how it runs and sounds......

Did your wife ever comment on the red ring around your mouth (compression test) and believe that you have been using the hoover? a lot of people did in the past. ps i don't do that now

I thought 150psi was a normal reading, not 90psi??
