Hi new the the channel but really like the video u make for ppl and educating us about all the different type of jet ski, I would like to see of a video of a fully built 1988 js550
Hi John , great video on how to measure squish ............ what's missing is WHY measuring squish ...............WHY is quish important to check ..................WHAT is squish do to your engine ...................WHAT can go wrong if you don't have the right squish ..................... in a few words getting more education on that word "SQUISH" ............ Best regards from Belgium.............JACK
Sorry it is hard to see as I get "off Camera" but when measuring please make sure you measure ONLY the very end of the soldier. Remember the squish band is tapered, and is at its thinnest out at the very edge. This is where you NEED to measure. You really should turn the calipers 90 degrees to the soldier.
Is squish always .045 on all 2 strokes? I agree with lucievedl. You need to do another video and explain why you would do a squish test and the pit falls of too much or too little squish...and how to correct squish if it is out of spec...and what would cause incorrect squish in the first place? It is very important to know the proper way to do a test, but it is more important to know why you are doing the test in the first place. I am not trying to be overly critical, I just think this video left more open questions than it answered. Should I check all my old 2 strokes even if there are no performance mods on them?
Thanks for watching Dave. Yes I assumed people knew why to check squish. NO .045 is not correct on all 2- strokes. Squish goal will depend on may different factors, head dome design piston crown type, etc. I was just commenting that on THIS particular build, we were good.
Off topic… did you end up getting any numbers on that 2023 EX? You had mentioned a possible 5 mph gain. Did you end up getting a wrap on it as well? I have a 2020 and I don’t like the black top deck. Just wondering how a wrap will actually hold up over time..
