WD-40 on two-cycle motors

Hello folks,

I haven't written a post in such long time that already I forgot how to begin writing. :)

I just received a good tip from a fellow jet skier asking me to post this info. It's about the use of WD-40 on two-cycle motors. Thanks for the tip, Tim!

Here is his email...

Please post on the blog.

WD-40 is that wonderful all purpose lubricant and corrosion inhibitor.
Those of us who grew up in the old school jetski days used it as a starting
fluid instead of traditional ether based starting fluids. Why? Ether has no
lubricant, and in a two-cylce engine it will start but strip the oil from
the cylinder walls, resulting in piston ring and cylinder wall damage.
WD-40’s propellant was isobutane and propane, which ignited well, and the
liquid WD-40 carried in the aerosol stream momentarily lubricated the
cylinder walls at ignition.

However, WD-40 propellant was changed in the late 1990’s to C02 (a
non-flammable gas) to accommodate transportation & shipping restrictions on
volatile materials. It really doesn't work well anymore as a starting fluid
for two-cycle motors.

Most starting fluids currently sold have a lubricant added to the ether, so
they are less harmful to your rings and cylinder walls. Read the can.
Although ether still is highly explosive and too much can blow the head off
the motor. Be careful.

Ultra 250X: A hungry 2007 gas predator?

Ultra 250... To be or no to be

Will the Ultra 250X be a top gas predator on the fuel chain for 2007. I doubt it, even though it's very heavy, 903 lb dry weight, and the supercharger not making it any easier on gas, the fact is that it comes with a fuel injected, 4 stroke engine and a root type supercharger that produce a very large amounts of boost at low rpm, plus, all the technology available today, make me think that it won‘t take that much more gas than its late predecessor: the Kawasaki 15F. The LX model should be closer to the15F gas wise. Common sense dictate going for the 250X, even if the extra speed isn't needed, because the future resale value, with the supercharger, will guarantee a higher price at selling time.

Power, as it comes from factory, should be more than sufficient for great hole shots and top speed but, eventually, lots of people would want to do some performance modification by 2008. The good thing with the X is that if you don't use wide open throttle too often, it won't be so bad! After all, you can’t be going over 70 mph in chop and look for chicks at the same time!

These machines will be writing history in the jetski records books before long. Few hardcore enthusiasts will be making 400 hp, monster jet skis, out of them when the aftermarket come forward in 2007. That's the problem with speed, we all get used to it very fast and want more. Hurrah, who would have though, in 1990, that it was going to take close to 80 bucks to feel up a jetski. Big deal, it’s just some burned gas going out!

Many professional racers are presently waiting, very anxious, for the Kawasaki manufacturing plants to release it so they can give it a try and to start working on modifications to get them ready to compete in regional, national and world finals championships. Soon, very soon, Kawasaki new predator, the Ultra 250X, will be making its debut at the dealers, all over the world, to claim the spot at the front of all others personal watercrafts. Want to bet which will be the fastest personal watercraft?… and the most gas hungry one? Good luck guessing!

Limited Kawasaki 750 SXi Pro Aftermarket Mods

Limited racing Kawasaki 750 SXi Pro standup jet ski!
My Kawasaki 750 SXi Pro standup jet ski came with all type of racing modifications already applied to it by the previous owners. Back then I didn't knew, or wasn't concern, about the different riding style available. Later on, I did learn that there also are freestyle, standup jet skis, that worked great for doing tricks. I saw a few of them doing back flips at the World Finals in Havasu, and really like it. I should be happy with my SXi Pro, at least for a while, it will allow me to become good at riding a hard to ride standup. I was told by a very reliable source that, once I mastered the SXi, I should be able to ride anything at top speed very easy!

When modifying a jet ski for racing you go a different way than when going for freestyle. In freestyle, for example, you are looking to get air bound easier, so, the shorter the back of the hull, the better it's. It's quite the opposite for jet ski racing where you want the ski to get a grab of the water at all time. For this reason some jet ski racers will install the hull extensions at the rear of the jet ski. They are designed to push the jet ski nose down for a better pump hook-up in rough water conditions. Mine has the hull extensions and sponsons, or tubbies as they are also called, for that purpose too!

Aftermarket modification on my Limited 750 SXi Pro:

MSD Ignition Enhancer - Boyesen Reeds

Factory Dry Pipe - Novi's 46mm carbs & Primer Kit

R&D Head and Manifoldm - R&D Timing Advance Kit

Cold Fusion Fuel Pick Up - K&N Air Filters W/ Adapters

Speedwerx angled Reed Spacers

Engine bored to 81mm

UMI Straight Handle Bars

UMI Pole Spring Tensioner

R&D Intake Grate

Blowsion Hull Extensions

Worx Ride Plate - Blowsion Tubbies

500 GPH Bilge Pump/Float Switch

Skat Trak Prop - Hydro-turf Mat

Almost here... Kawasaki Ultra 250

Ultra 250 LX or Ultra 250X... A big extravagance either way!
Today I was just looking into the new Kawasaki Ultra 250 and realized that it's only about one more month for the new 250X jet ski to start arriving at some, fortunate, Kawasaki watercraft dealers in the USA. These new jet skis are in accelerated production at all the Kawasaki manufacturing plants. They are trying to fulfill a big demand from all over the world. Consumer's purchase orders are in waiting lists at the dealers all over and the public waiting anxiety is building up very fast. Many people are going to be very happy when it finally comes out!

Almost everybody that knows about this ground braking, supercharged 250 hp, beast wants one and most likely, many costumers, will be paying an extra premium to be one of the first enthusiasts receiving the high performance jet ski. There has been a lots of traffic, and questions about it, at our Ultra 250X related site. The funny thing is that, from the total amount of jet ski enthusiasts in the world, only a very small proportion knows about the existence of the Kawasaki Ultra 250. Good luck on trying to get one in January 2007!!!

Standup Jetski Curiosity

My standup jetski curiosity started long time ago, for quite some time, I was looking forward to give a try to the standup jetski riding style but I had no ski available. Since standup skis were the very firsts in the personal watercraft beginning, the original ones that started the PWC revolution of the 90s, you will find that the standup jetski population, somehow, feel king to PWC and look down to the seat down or runabout jetski rider, as they are call at the racing circuits. It's due, mostly, to the standup ski been harder to ride than seat down personal watercrafts. This resentment may be in part due to the seat down been easier to ride and getting, extremely, popular in the last few years. Therefore, many of them, refer to the seat down ski as "cough", sometime, in a very offensive manner. This class division make is a very strong source to heated discussion and point of views at the different PWC forum online. A very good place to learn about the standup ski is the PWCToday Forum.

Got the "Standup jetski curiosity" out of my mind by buying a modify Kawasaki 750 SXi Pro from a personal watercraft ex-racer at San Diego, Ca. By the way, I discovered, I have lived for more than 30 years next door, Los Angeles, and didn't know about it, San Diego to be one of the most populated standup jetski area in California, the nation, and perhaps in the world. By the time I got my SXi Pro, the season was almost over and I couldn't get much use out of it in 2006. Even though it was hard to ride standing up at first, and I fall a few times, by the second outing I was capable of riding up and felt the excitement, the thrill, the rush, and water spray hitting my face and soul... A great feeling of youth for an old timer like me!

I'm glad I got this "baby standup ski". When the 2006 PWC World Final Championship took place in October at Lake Havasu this year I was hating life , this event is my personal weather alarm letting me know that my jetski season got cold and is all over, because I just gotten hook on riding the SXi Pro, I rode it only in 3 different occasion, and even with just a little taste, I was feeling like a teenager again. Because I couldn't stand up the first weekend out with the SXi Pro, I’m superstitious, I did shaved my bear trying to fool the ski into thinking that I was younger... I think it worked... I was up by my second camping trip!

Now, I want more, a lots more of the standup riding ski, in my case the Kawasaki 750 SXi Pro. I still love fast riding, jumping, and seating down, sometime, in my 2000 Kawasaki Ultra 150 jetski. What I have learned so far is that standups and seat down PWC are made with two different type of entertainment in mind. In the standup ski, you can feel the rush right from the start and without having to go very fast but you’ll have to be in good physical condition for the workout you going to get out of it. In the runabout or seat down jetski, you don't have to do much work but to get the rush you have to go really fast or do a lot of jumping. Heck, you can even do some fishing out them if you want to. I will enjoy riding either one of them based on what I feel like that day. They are both a very thrilling sport and should always be conducted in safely and respectfully manner to restricted areas, swimmers and fellow boaters around you! Get an standup ski and feel the rush! View my Kawasaki SXi Pro jetski video

Kawasaki Ultra 150 Modifications

Learn what is needed by this great PWC.

The Kawasaki Ultra 150 that was originally a very unpredictable jet ski became a tamed one with a few bolt on modifications. As we all know, the ultra 150 jet ski, was made a high performance rocket from factory and it took the speed title as the fastest stock personal watercraft produced and sold at that time. The handling modifications that follow made a big difference in sharp turning and the kind of water that you can ride in at full speed. They were and are well worth their cost and the effort involved.

There are many types of modifications already developed for the ultra 150 and the only limitations are, usually, the high price they will cost you. I have known of ultras that went over, a verified, 80 mph on radar or gps devices but, it took big $ in doing the modifications to get there. I know of a guy, Daren, that got his ultra 150, to run stable and reliable, up to 81.1 mph and then, he sold it because he had reached the hulls speed limit. That was his claim and I believed him since he documented the complete modification process, video taped the speed runs, and it can be viewed at a couple of related forums online. Some of the many types of modifications that you can do to PWC should include; handling, performance, safety, comfort and cosmetics. You could do them for recreational or circuit racing purposes. Most people that get involved with recreational performance modifications are going for raw top speed gains in order to beat somebody at their water hole. Circuit racers, on the other hand, are looking more for acceleration and handling combined with top speed.

Modifications cost will vary depending on "used versus new" and how good and lucky you get when looking for aftermarket parts. The best prices can be found searching on online at ebay and the many PWC forums that include classifieds sections, these seems to be the cheapest way. Be aware of the risk involved when buying online. I'm not related with any shop so, I can't control what the aftermarket parts will be selling for!

Which is the fastest PWC?

Well, nobody knows yet which one will be the faster jet ski in town but, no matters what brand of jet ski you ride, be it a Yamaha GPR, a Seadoo RXP or a Kawasaki Ultra 250X, nor if you live in the east, west coast or another country, I still like to wish all racing and recreational PWC enthusiasts lots of luck with their next modification and jet ski racing battle. God bless you all... Papoloko!
