Good honest video of real world expectations. I have the same ski with a stage 2. Im at 1400 feet of elevation and 85+ air temp warm lake water. I run 84 mph and an occasional 85 when things cool down. The GP is a great platform to modify.
Here in Australia we just got socced with massive yearly licences & registration fee charges. It's costing us around $1000.oo a year just to own a jetski & trailer to keep it on the water. 🇦🇺😮💨
Jack Hollmann Great video . guess the next video will be about compression and high oct fuel ? lol.............many thanks for all the great video's !!! hello from Belgium
1) Don't have open containers of gas in a garage Especially with the door down. 2) Put paper towels down where you plan on spilling the gas ( dispose of by spreading outside immediately ). 7-P Principle. ☆
This needs to be shared all over the groups. This little golden nugget of info can save people so much money. Thanks again for a spot on and important video mixed in with an out take 😂😂😂
Rebuilt my carburetors twice and couldn’t figure out what was the problem also ski would run until under load it turned out to be the return line was clogged
Really enjoyed this episode and your tip about dropping a couple gallons into the truck before the jet ski tank, solid tip. So why is it that the watercraft industry hasn’t shifted to parts that are certified for ethanol blends. Seems like that is at least the normal in the US. Is it simply a cost thing, hp thing or something else. If the automotive industry did it, you’d think watercraft could too, but I’m no expert on the subject. Thanks for the great video!
Thanks for watching!! Honestly all of the new watercraft WOULD be ok for up to 10% ethanol. It is just the older skis. It is the same with old cars, lawn mowers etc. I still do NOT recommend ethanol fuel in a typical marine environment though as it can and will actualyl absorb water, and we are surrounded by water....
Thanks Glen most dont know how to do compression correctly. Also good to have a tester that threads into the cylinder as far as the spark plug and has the Shrader valve at the bottom (no adapter)
I have my father in-laws old 1996 tiger shark montego. It ran good when I first had it and now it won't run at all I'm getting a kit with the needle and seat and the Springs to tune .The info you gave on the intake pressure's or vacuum is a big help because I know this would have been a problem.. I will be ordering a stock flame arrester and cover thanks
Thank you for doing the video. I've noticed in a lot of the Facebook groups people are using Harbor Freight or other cheap gauges and getting inaccurately low results. Just today somebody had an engine with 90/90 using a Harbor Freight gauge. So using an accurate gauge is very important. If an engine has bad compression very often one cylinder is a lot lower than the other. So you wouldn't want to pull an engine to rebuild the top end based solely off one compression test. A fully charged battery is important too.
What I appreciate about John making these videos for us is the fact that he’s not profiting from slowing down his day and filming/editing these videos. He’s actually giving more and more to the community of riders, and future riders by making all of these wonderful videos for us.
Nice video!!! I always do mine with the throttle open but both plugs out. So when you do it and leave the plug/s in do you leave the wires on the plugs that are in the head or ground them put somewhere else? My skis will run on one cylinder 😂
Thanks for watching. On a traditional 2-stroke, When "I" do it normally, I leave a plug in, and I do ground both wires while testing to protect the CDI. I do not ground the plug in the cly for fear of it starting on one cyl. I use an extra plug in the boot, and ground it to the head. OR on Kawi's they have plug wire grounding posts.
@@watercrafttalk2738 I would think it should turn over more easily with the spark plug(s) removed because the starter doesn't have the resistance of compression. But you just showed us it spins faster with the spark plug in! I'm totally baffled why this is the case! Any ideas?
@@watercrafttalk2738 Wouldn't the down stroke be less compression than the upstroke where the firing event takes place? Anyway, I saw it spin over faster in your video with the plugs in, so I can't deny that. I'm just having a hard time wrapping my brain around it!
Thanks, I seen "pop off " mentioned on a FB group and was totally lost. Now that is out of the way, will visit your site as I will need parts here shortly. I have a Franken Jon and most likely will have to modify the carb to get more bottom end. 61 x is what I am installing as my 62 g and other 61 bit the bullets.
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..
