    ported engine theory. do I suck or does it suck?

    Dude, I don't need to prove my skill set to you or anyone else. started at 300sx remember? Who knows, maybe i'd give you a run for your money on a buoy ride. I'd probably "accidentally" fall to make you feel better on the drive home. OR you eat me up? If you need the win you can have it, "bro"...

    ported engine theory. do I suck or does it suck?

    at me if a 760 cylinder comes up for sale. I'm messing with that middle screw on the pipe first thing though. ***farts in the opposite direction of @DylanS to confuse him**

    ported engine theory. do I suck or does it suck?

    Not to get all philosophical but the more I've learned about engines the more I realize I don't know. I bought a ported cylinder and a motor with a blown x cylinder that snagged a ring. Sent ported cylinder to original builder and told them I wanted linear power. I thought lack of response...

    ported engine theory. do I suck or does it suck?

    I can throttle blip this thing at 25 mph without trying. The ski has power, it just comes on like its desperate. I just dont like that it has a "spot". I want it to feel like my 94, but its beast big brother and he takes roids like candy.

    ported engine theory. do I suck or does it suck?

    Maybe im being misunderstood. I ride really hard and really fast. If i could find one Id race. Not sure how saying i like to site see meant all i do is plop around. Not sure why a maxed out superjet cant do both, as if ported motors and pipes mean you cant take a moment to look at some rocks...

    ported engine theory. do I suck or does it suck?

    I'm...70% sure its a mod chamber. When I bought the cylinder I emailed art, sent all my stuff to him and had him do his thing. First thing I did was install the new prop and the ported nozzle. I was so happy with the snap on a 650 with a protec pipe I sat on the cylinder for a year. Then I built...

    ported engine theory. do I suck or does it suck?

    Yeah, thats pretty much exactly what it does. After 1/4 throttle it just takes off like a rocket. I bought the 94 for my ex gf and she wouldn't ride my ski because she was afraid of it. As far as the porting goes I couldn't tell anyone how mild or aggressive it is. All I know that its from...

    ported engine theory. do I suck or does it suck?

    It's just a simple wetjet single carb 46. For what its worth the timing is advanced on top of the msd curve. This ski is an absolute beast in the mid and i truly enjoy riding it. I just hate the fact that I wanted more linear power and what i have is a rubber band thing. We all have are opinions...

    ported engine theory. do I suck or does it suck?

    You're in luck matty! I'm back home close to the edge. Ride both and tell me what you think. I donno man. Maybe I'm missing something simple but right now I'm thinking what was the point.

    ported engine theory. do I suck or does it suck?

    I've rode an eme one time and it sucked. Tippy mess. Now the same bro let me ride his vision and it was like a superjet on steroids. Thank you, velociraptor. Yeah, I'm going to seriously screw with the.....screws next year. The motor just runs so hot I'm afraid to lean this crap out. But i...

    ported engine theory. do I suck or does it suck?

    Man, maybe I'm just bored, I donno. Or maybe I'm right (probably not) I have 3 skis. a bone stock 94 sn, a 91 sn 701 transplant ported with every gadget possible besides big bore and zeel., and a kawi 300sx. The 91 is my main ski. It's a ported x motor at 718cc, a set back Skat mag pump...

    Pay pal sucks

    Paypal works off scripts based on how frequently you use the service. So if you don't use it much and all of a sudden they see you making a high dollar transaction its auto-flagged till its figured out.

    Ada stud material

    Well considering 316 is the marine variant and contains moly which is basically super metal I'd wager its 316. Or you can, you know, call ada.

    How i turned my superjet into a Surf ski

    +47 street cred for the awesome craftsmanship and killer paint job. -46 for making my ears bleed seeing it. Neutral on the bilge paint. I'd never find a 10mm nut or corresponding washer again. You must have the hands of a surgeon

    New hull

    @kevbo i get what youre saying completely but its not like we can head to the local dealer ship to get meaaured out and test ride multiple hulls made by various companies. You can get a suite tailored or fitted for a mtn bike but as far as this goes youre left hoping people are ok with letting...

    New hull

    Mines in pieces wrapped up in plastic, but that little pos was my first ski. I loved every second trying to get balanced as i watched the sun go down waiting for it to plane out.

    New hull

    I know youre joking...i hope. But a lot of things Yamaha got it right for overall freeride fun in 1994. A handful of guys got it right for flatwater freestyle years and years later. Theres always gonna theoretical better material options for our sport. But unless you can sell 50,000 skis a...

    Super Jet Zeeltronics CDI for a 760 RN superjet

    I dont mean to sound like a total douche rocket but yamaha figured out the science in 1990. If u wanna go thrash and be rad as hell it'll cost ya 3 to 7k. Or you can spend 30k to try to make it look like it was super hard to make your backie cool cause you tilted your head.
