You have some great mods on your ski! New Kawasaki Ultra 310 owners totally benefit from you using the mods first and are basically our "test bed" for the products. I also appreciate your honest reviews about what works. I'm going to get the belt tensioner and new stock pulley at the end of this riding season and maybe a few things from Unlimited PWC too! Thanks for posting JD!
Haha thanks for watching Jerry!! Yep, there are a few mods I’ve done that are absent from this video…just because they didn’t work for me doesn’t mean they won’t work for others…but everything mentioned in this video I would personally stand behind! Also some things may last decades in fresh water but only a few months in salt…the parts I endorse or run myself all have proven themselves in a salt water environment- which means they will hold up to pretty much any fresh water as well!!
Yes we ride in very extreme conditions so you can use me as the test dummy to see what holds up and what fails. Hopefully we will get to ride again soon- I was talking to Tommy about going next weekend
@@JDsWaterWorld No doubt Kawasaki makes a few badass Jetskis! Gina is dead set on if and when her Kawi loses a motor she will have it rebuilt/replaced and rock out.
Very SMART of Unlimited to comp you their catalogue because people like me will indeed purchase item that you have on your skin. Since I have your exact skin year and model I will just copy many of your suggestions. Although I dont need some components as I’m a fresh water rider (unless I trailer frame GA. to Fla ) 75 % of the gear, accessories etc you recommend is on my purchase list. I never heard of Unlimited and a couple other companies until you recommend. I do t have to even think twice about a purchase after your recommendation. I hope these companies continue to appreciate you. AND Kevin Shaw as well.
My top choices from Unlimited are definitely the traction mats and the valve cover! I didn't have as good luck with the exhaust tip or flush ports because of the salt- the beautiful parts started to corrode but if you ride on fresh water they will hold up much better. Thank you for the comment! These parts and other recommendations I made across my channel are based on products I actually use- I accept no commissions and don't make any money from recommending this or other products- I do it all only to help others guide their decision making process!
@@JDsWaterWorld you are one stand up guy. Honest, and reliable in your straight forward analysis. It really is a blessing for us jet skiers to have a VERY reputable source. I’m grateful
You've created one hell of a ski, and all the green billet aluminum and the traction mats make it look fantastic too. I'm looking into a few things for my GTR right now - potentially a custom rack that mounts to the LinQ system, so I have a more universal way of hauling cargo, and I'm aiming for it to be able to hold 70+ liters of fuel. Plus I'm picking up the Ski/X package module from my dealership in a couple days, so I'll have launch control as well.
Thanks man! I appreciate you always commenting and the support. I have had “0” expectations about this whole thing, so glad the channel is providing a good resource to Kawasaki fans
I feel I now need to install the K-Speed stage 1 kit and KP "saltwater" package before I even put 1hr on my new ski. Quick way to spend another 2k. Also, Props on another great video and for promoting the companies that comped you their parts.
Thanks man! The ski is fine stock, with the exception of the supercharger pulley which really does not hold up well in heavy salt water riding- the tensioner mod reduces maintenance since you won’t have to grease the pivot bushing. The Kspeed Stage 1 provides very noticeable increase in hookup, responsiveness, and speed- and Kspeed did not provide this to me for free or even give me a discount - I paid full price
Thanks for the great video JD! Can you please drop the links to some of the parts websites you showed at the end of the video? I dont see them anywhere on your page or in the comments. Thanks
Well there’s Kawi Performance (Kawiperformance.com) Kspeed (www.brisbanekawasaki.com.au/collections/ultra-310-2022-performance) Unlimited PWC (unlimited-pwc.com) And I think that’s it!
Nice mods, still have my 2011...runs like a top with reflashed ECU. Ocean riding is hell on a ski, my maintenance schedule is basically nothing except oil changes. Also, I collect blowby in a custom catch can and don't drain it back to the sump! Keeps oil MUCH cleaner. I only run Amsoil 10W-40 signature series
Lots of people have been recommending the amsoil these days. I’ve been running the KPO Jet Ski oil because it’s the only one that’s JASO MA and MA2 and was told by Kawasakis head tech line tech that it contains a specific additive package developed by Kawasaki and the supplier
Hey JD , good news is that your videos are starting with a commercial and having commercial advertising in the middle. Hoping this helps monetize your channel as it’s quite valuable to us kawaski 310 owners

Hey JD question for you about the aftermarket handlebars. Is there a mount kit that would mimic the tilt feature that comes standard? It's something I use quite frequently to adjust the position of the handlebars when I switch from a sitting to standing position. The whole ripping apart the assembly does make me nervous as well.
There’s a bracket for the stock adjustable riser that allows you to use aftermarket handlebars but keep the tilt. I think the tilt assembly has too much “slop” so I like the fixed riser. You can easily swap back and forth there are no permanent mods done to remove or reinstall it
@JDsWaterWorld Thanks for the info! I'll have to dig into it a little more I still have a few months to make a decision before the season starts here in Wisconsin.
I just got a new 22 ultra X and I’m struggling to find the OEM style speaker pod enclosures. I’m mainly just trying to find the enclosures. Cause I’ll be running my own brand equipment. But I can’t find them
@@JDsWaterWorld what is a Microfiches ? I’m a tech by trade and done car audio etc as a hobby since the 90’s. So I know for certain I can run whatever brand equipment. Such as amps / speakers etc. but I don’t like a aftermarket look on stuff like boats / bikes / JetSki you know. The speaker pods I keep finding don’t look like the ones I see that comes factory on them. I mostly just want to run the 2 lower speakers. I think Kawasaki was drunk when they thought to pile up more on each side of the display screen Lol a set of components on each side is perfect
Whats your thoughts on running the kspeed or riva wasgate block off plate. I believe my factory wastegate is beginning to bleed off a little boost. Just wondering if there are any major downsides. Ski is a 300x in good health. Basically stock but have kspeed stage 1 on order
I never go in saltwater (now) (I’m too old!). I do however go in a lake that has water that is alkaline. Will this have a similar effect on these (swapped out) components? In addition, will these swapped components effect the ski in normal lake usage. Note: the saltwater where I’m from is not like in Southern California or Florida. It is cold. And as I said, I am old! 😂😂😂
@@JDsWaterWorld Also, “Unlimited “ I can’t find them. Also looking for those four videos on the upgrades. I hope to find them today so I can watch them tonight.
JD quick question, not sure if you've replaced your ride plate yet but.... I put K-Speed KS1 plate on my 310 LX, however the speedo kinda sucks now. Only indicates 45 MPH at top speed when I'm doing 70 MPH+. While I know the speedo's are not really all that accurate I wish I could get a little closer to the actual reading. Any suggestions???
I’ve ridden a ski with that plate, and didn’t have any issue. Are you sure you installed it right? Did you damage the paddle wheel by chance? Double check it’s tight? I haven’t heard of the Kspeed plate causing any issues…double check it and check the wires as well..and if you still think it’s the plate, email Kspeed, Jamie and Marty offer first class support
@@JDsWaterWorld Pretty sure, as I have it on 2 ski's and they're both doing the same thing. Tried with the shims and without...same result and the paddle wheels don't appear to be binding.
I’d love to slowly make these changes as well but the shipping from kspeed and unlimited is super expensive. If there’s anything you take off I’d be interested in purchasing them from you.
Hahah I’ll let you know but if I take something off chances are I was not happy with its performance or it failed on me..and I’m either of those cases id feel bad passing it into someone else! Yeah I’ve seen the exchange rates right now are definitely not in our favor!
@@JDsWaterWorldwhat do you use for mapping out your trips of just knowing where you are located? iPhone app? Thx. I need something simple for large lake riding to make sure I get back to my original launch. 🤣
Very interseting JD, well done to all the mods, and it runs even better. Your channel is great and will grow fast. I have question, l have the ultra lx like your other one.. l have notice going in a straight line,the steering is just a tad to the right and when l put it perfect ly straight then l know its not perfect,because ski starts to go slightly off course to the left,its not much . The problem with daring to adjust it, there's no way of knowing if its now better,without testing it, you could be adjusting those two rods 10 times, perhaps l should judt leave it as is. Or perhaps its right but ski slightly drift off couse,and is normal ,appreciate some advice.
Kevin, that’s an easy one- just give the brass steering cam one or two turns- then measure the distance on either side of the exit nozzle to the mounts for the reverse bucket and adjust until it’s centered and the handlebars are straight. You can adjust it pretty good on land- then water test and tweak as necessary. This is an easy adjustment, so shouldn’t take too much on your part
What weight is the oil? Probably fine, but I would personally use either the KPO Jet Ski 10-40 full synthetic which has specific blend of zinc etc or VR1 oil. I have not personally run any other oils in my Ultra 310
What pulley do you recommend if I want more boost than stock? I was gonna go with k speed 108mm and I do only ride in fresh water but still concern about it rusting and damaging my belt.
If you’re only in fresh water, you will be fine with that Kspeed pulley and idler. The Kspeed 108 pulley itself was completely fine, just the larger automotive grade idler is not suited for salt water riding and I was not able to source once that was. Industry experts took the time to tell me that I should not be running extra boost if I wanted my engine to last…they were speaking from experience and specifically the pistons will tend to fracture- unless you upgrade them to forged, the factory ones really are not rated for more boost than stock- I am not the end-all on this, but after listening to multiple voices telling me that I should only run a stock size pulley and keep the BOV, this is what I did. Unless you have a race team and sponsors that can pay and out in the hours to rebuild your engine for you…I’d stick with stock boost- this is my opinion and not necessarily the end-all just keep that in mind
@@JDsWaterWorld Thanks for the advice, i did not know more boost could damage my engine. definitely trying to keep it relatively reliable. what are your thoughts on the stock Kspeed fuel rail? Could it cause damage to my engine in the long run?
The fuel rail won’t damage anything- I just added a pressure gauge to mine and will be reinstalling it. The Kspeed 108 setup is honestly probably fine for most riders- I just personally won’t be running any extra boost again or a block off until I upgrade to forged pistons…I run in high heat, salt, abusive environment and it never hurts to run the machine on the conservative side.
The stock size supercharger pulley from Kawi Performance- only because the stock steel pulley doesn’t hold up well and is an embarrassment to Kawasaki- whoever signed off on that steel pulley should lose their job
The oem tensioner and oem idler pulley are really fine- just the tensioner needs the pivot bushing greased every 50 hours or so- OR you can add a zirk fitting for like $5 and that does the trick. But yes that would be my second,the KP part is essentially maintenance free, although he does say to change the idler bearing at regular intervals - but that’s cheap
Kspeed Stage 1 ECU tune itself will give you impressive gains…our testing we did mid 70s with the tune alone from both Kspeed and Riva regardless of rider weight. If you want to be fastest on the water, it won’t be on an Ultra
You want a balance between performance and longevity. The higher performance, the shorter the life…the key is finding the perfect balance between the two- that’s what I’ve been trying to do with my conservative mods. De-pitched prop will mean higher rpm, which means more wear on the engine..yea you’ll be faster, but that at the expense of the life of your machine.
Well the ECU alone can do that…see this test we did: 2022+ Kawasaki Ultra 310 Jet Ski ECU Tune Comparison - Riva vs. Kspeed vs. Stock ruclips.net/video/4I_IJLjjDE4/видео.html
Kawis has the best hull, and engine components, but is way too spencive . You have to be sponsor by a company or have a lot of money.is not for a middle class customer.compare to the competition.and not to mention the labor,is very hard to get a macanic that knows Kawis and like to work with them.
There are plenty of used ones at very decent prices all over the country .Really they are not that much more than competition..you get what you pay for. The Kawasaki’s also have much better resale value. I agree 100% about the maintenance aspect- the Ultra 310 is a very complicated machine and many shops don’t know how to service them.
You send me a set of forged pistons and titanium valve retainers and I’ll install them…..I brought the ski up to Kspeed Stage 3, then brought it back down for a sustainable and reliable balance of performance and reliability. I’ve got the Kspeed tune, top loading intake grate, 2 degree pump wedge, stainless idler pulley, billet supercharger pulley, billet sponsons,….I’m not tryna win races, don’t need to be forcing 18psi of boost into my engine while I smash through the salt water at 67 mph…I’m not out to blow the ski up. It’s all about the proper balance…

There are plenty of used ones at very decent prices all over the country .Really they are not that much more than competition..you get what you pay for. The Kawasaki’s also have much better resale value. I agree 100% about the maintenance aspect- the Ultra 310 is a very complicated machine and many shops don’t know how to service them.
ur awesome. but at least do mods that increase performance. same pully size, valve cover, etc. Its mainly veneer. Where is the performance?
You send me a set of forged pistons and titanium valve retainers and I’ll install them…..I brought the ski up to Kspeed Stage 3, then brought it back down for a sustainable and reliable balance of performance and reliability. I’ve got the Kspeed tune, top loading intake grate, 2 degree pump wedge, stainless idler pulley, billet supercharger pulley, billet sponsons,….I’m not tryna win races, don’t need to be forcing 18psi of boost into my engine while I smash through the salt water at 67 mph…I’m not out to blow the ski up. It’s all about the proper balance…
