    Recommendations for a Sport Spec Blaster

    Hi - I was originally planning on building a Sport GP Blaster with an 1100 motor, but it seems that I won't be able to race it in some organizations, since I'm not a pro.

    Soooo - it looks like I'll be going the Sport Spec route. My plan is to pick up a nice stock Blaster and go from there, unless I can find a good deal on a Sport Spec ready to go in the SoCal area. I'd actually prefer to build it myself so I know things are reliable and fresh.

    The first issue would be the motor. I understand the 62T cases are the way to go, with probably Boysen or V-Force reeds. Can these be ported, or do they have to remain stock? With cylinder - does 62T or 62X make a difference? and do those get ported or remain stock as well?

    Head - I'll most likely go with ADA girdled with the 35cc domes.

    Ignition - Msd Enhancer is still available, so I'll get one of those. Are charging lightweight flywheels OK?

    Carbs - Could I use something good like Full Spectrum carbs?

    Pipe - that's probably the biggest question. I know the rules say it has to be a "wet" pipe, so what's the best option there? Factory Mod or Limited??? How about those carbon fiber pipes?

    Waterbox - is aftermarket OK? Best to locate under the battery area with rear exhaust? Recommendation for kits?

    Anything else I'm forgetting?

    I'll also be needing recommendations on sponsons/hull extensions/intake grate/ride plate.
    I see a strong recommendation for a Hooker 10/16 prop. I assume the whole pump/shoe/nozzle stuff has to remain stock? No aftermarket or setback pumps?

    Thanks everyone

    John

    Re: Recommendations for a Sport Spec Blaster

    I have watched Jet Ski racing since the late 80's and Jet Ski racing is
    boring to watch, unless it is in the surf.

    I have never built a modified Blaster before, but I have fixed failed
    attempts.

    I am not a fan of the bigger is better attitude, and I believe spending
    money on big modified carbs is a waste. Besides, nearly everyone is
    doing the same thing (big carbs). Where is your advantage?

    Seems like most people think about getting off the line first, or winning
    the race to the first buoy. But I'll bet most people don't think about placing
    one hundred yards to a 1/4 mile behind the next person because they
    were caught up in the other riders wash.

    That was true 30 years ago, and now with the longer tracks for the
    fast 4 stroke 3 seater's, there is an increased chance of being just a
    straggler instead of a contender.

    No porting on the motor at all, cases or cylinders. Factory B Mod, preferably with a TNT chamber. Carbs/intake is just whatever your budget can handle, lol. You have to keep the flywheel stock, run the msd enhancer. You can set your pump back with a wear ring spacer, 2", no aftermarket pumps.

    Excellent advice - thank you. I found a good donor ski which has the 62T cases and a FPP/TNT chamber already. Purchased a whole 62T motor so I can use the cylinder from that.
    Appreciate the input!
