    95 Yamaha Waveraider upgrades?

    I am purchasing a 95 waveraider 1100 and wanted to get some info on it. I am interested in upgrading, but do not want to open the engine. The bike has 97 hours on it and it looks ( even the engine) brand new.

    The owner says that he has done 56 mph on it and I was wondering:
    (1) What is the stock top speed on these bikes.
    (2) What upgrades could be put on the bike for it to run 65 mph
    (take into consideration limited resources $$$)
    (3) What would be the most efficient way to achieve the 65mph performance and not lose the reliability of a stock engine?
    (4) What oil and how much of it should I put in the tank with a full tank of gas?

    I don't want my bike to be breaking down. Just want a 10 mph increase in boost. I have gotta beat my brother.

    Actually 65 is slow for a Raider....most will run closer to 58mph stock....

    In terms of getting the ski in the performance ranges...get out the check book. Nothing on water is close to cheap period....and to get much more from you ski, you will be doing some engine stuff. You can get 61 maybe 62 with intake grate, ride plate, air filters "known as F/A or Flame Arrestors", prop etc.

    In my personal 2 cents..


    1. Mill stock head for 150 PSI
    2. Run 13/19 Solas prop
    3. Cut the center bars of the intake out. "glass water"
    4. Pro-tec shortie ride plate
    5. Riva F/A installed, choke plates removed and primer installed
    6. Install a fuel restriction in-line if you don't have the carb update kit.

    That's basics....if you want more.

    7. Taper bore the 38's...or go up to 44's
    8. R&D, Pro-tec, Riva intake for the 44's
    9. Porting..although the 63M is not the best for porting but... an option
    10. Riva CDI ...just seen one for sale.
    11. Group K sleeper kit.???
    12. Big bore kits...and upgraded cooling...
    13. 65U engine swap "GP 1200" 110 hp vs 135 stock stock

    RESPECT!!

    Thanks for the info fellas. However, that info got my head spinning. What the..........is some of these things? Mpeavler, appreciate the detail, but if you can help me understand these things that will be great. Especially price estimates on the said parts. Also, where would be the cheapest place to get the said parts?

    I will say....I am not gonna open the engine at all. Opening engines comes with many expenses and human error. However, the bike has a couple of goodies:

    (1) Free flow exhaust with prop
    (2) Intake grate (2 bars)
    (3) Ride plate

    What make and model of these things, I have no idea. Question: What speed do these bikes normally do from the factory? Also, do these bikes have restrictions on them that can be removed for increased performance, but that will not damage the bike?

    Thanks again for the help fellas.

    There is no such thing as cheap in skis....if you want to go fast...you will pay $$$$$$$ to get there. Anytime you mod, you take away life span period. If your looking for an everday cruiser...modding is not the sport to take up. If you can do the work yourself you save money...but it still requires basic metric tools, compression gauges etc.

    Bottom line is how fast do you want to go....and how much are you willing to spend to get there. The easy way to run 65mph is send your engine to someone like Tim Judge, Dan Lamey, Group K and tell them you want 65mph....along with your CC numbers, Exp date and the security digits on the back.

    including what I paid for my ski and the cost of the trailer I have about 5000 in everything and my ski is going to be pushing 70 real soon "wink" so if you can do alot yourself it can be done on a budget..............



    and 65 is very respectable for any ski that only did 56... 58 stock


    and I really disagree with the life span thing ask gpsleeper how many hours he has on the title holding 1st place vintage ski ......

    Welcome to the Yamaha Old School forum Rasta.

    I suggest that you set aside about 3 or 4 hours free time and then type "1100 Waveraider" into the search feature. This will definately give you an education into the ski that you are about to purchase.

    whoa whoa whoa....I never said it made it a ticking bomb....in reference to Brandon's ski....but if you compare engine life ie bearings, rings etc of a high compression engine vs a stock....you WILL lose life span from the engine. Group K does mild work....I know I had their engine in my old raider. Please tell me that at 195 PSI your and my engines would last as long as a stock raider with 110 PSI.....it ain't happening.

    Well...I agree with the lifespan and reliability...that is why I am stuck on not opening the engine until it forces me too. Then I will upgrade the interior of the engine. However, for now it will be exterior upgrades...like...air filters, exhaust etc. When it comes to things like those....I will do the work myself in order to learn about the ski and to save some $$$$.

    However, I do want to know how u guys run your ski's......I have heard about oil pump problems and block off kits.....Have u guys blocked off your oil pump? What is the right ratio and oil mixture to use? Any suggestions about where to buy these upgrades from for increased performance (ex. air filter, cars, exhaust?

    good point...... i just dont want everyone to get the idea that if they mod there watercraft that its not going to last as long. Most of the small improvements that modding does actually increases the life of the motor. Only when you go extreme does it start going against the life of the motor.
    Man you have to remember that alot of people who just read these threads dont know as much as you or I about the specifics of these issues and are looking for just a quick answer without looking into it.
    I was just trying to make the point that its not all about the money or tearing up a ski trying to get it to go fast......rather pass on the enjoyment of building something for yourself that when you ride it you will be proud of your accomplishments.
    If we tell everyone that you have to spend a ton of money and it shortens the life of the ski then you will discourage anyone from following in your footsteps.
    I think what people need to hear and probably what some of you guys need to step back and ask yourselves. This is a really FUN hobby to have. and its alot of FUN modding skis too. "am I enjoying myself?" For me its an everyday joy to wake up and either work on my own ski or read about someone elses victorys or problems that they are going thru. Im sure im not the only one who spends more time on this site than they should.

    I guess what im trying to say is lets try and keep a positive outlook on helping everyone including the new members, keep giving them the idea that modding, can and is an enjoyable addiction in itself, and with a do it yourself attitude, can be done without spending an arm and a leg too......
