After watching this video of mark gomez's 550 It really made me miss my old 550sx. Didn't have much balls, but it sure was fun. Sometimes I just get sick of my superjets stability. The 550 was so loose it was a blast. I'm thinking about buying an old project ski now to mess with through the...

I have a few quick questions before I rebuild my top end. -Does anybody have a pic of how much I should chamfer my ports? -My 61x is getting bored over to 82mm. I will be running a stock head for a few weeks until winter sets in. Will the stock head be ok with a cylinder that is 1mm...

I blew up my 61x 701. I need new pistons, a bore, and a head. How big should I bore it? Is it worth boring over what I need or will the power gain not be noticeable? Also, Will the new pistons come with something that will tell the person boring what ring end gap and piston to cylinder wall...

6m6 ignition box on a ported 61x. Westcoast head but was only making 150psi after porting. First tank of 87 octane and kaboom. My old stocker 61x ran on 87 all day long but apparently porting can change detonation characteristics alone. It looks to me like it detonated itself apart but I...

I built a 61x this year that was ported and piped. I was running a Riva ignition enhancor until last week when it failed. I swapped it out to a 6m6 CDI and it ran great. After the porting with the westcoast head i was only making 150psi. So I assumed since I was running OEM ignition and...

So a couple days ago my ski just died. I wiggled the start stop switch around and it would refire for 15 seconds or so then die. I did this all the way home. Then when i started working on it, while cranking, it would spark for a second and then nothing. As soon as you would hit the start...

Ive seen it all now. Took my ski out today and it just dies, start it back up and it dies again. Rode it home in 20 second intervals. Thought for sure it was the standard lanyard/stop switch issue. Unhooked the black/white connector and still was dying. Put a spark checker on it and cranked...

I just took apart my pump this winter on my 94 701 sj and I dont remember there being any shims at all. Is this common?

Great seller. Would buy from him anytime. Honest and fast.

I have a sqarenose with a riva red pipe and am wondering what im gonna do when the hose blows out...because im sure it will eventually. Are there any other options except find a used stocker and chop it?

I always see surf vids where guys just come haulin azz up the beach and slide to a stop on the sand. Doesn't this destroy your intake grate and prop?

I've got a riva red pipe that stripped out the 3 mounting bolt holes. I borrowed a helicoil kit from my dad and somehow used the wrong drill bit to drill out one of the holes. So now I've got a HUGE oversized hole there. Ive been told to fill that bastard with jbweld but IDK how strong it...

I was driving home today dreaming of jetskis when I thought about cutting a squarenose hull and doing thousands of hours of fiberglass work for fun. I thought, if the the square hull rides nice, why use a 300sx? I thought to myself: "I could just cut 10 inches off the front and 2 inches off...

After this weekend of riding for 1 hour and having the bolts fall out of my pipe mount and my riva red pipe that I spent hours cleaning up and repainting cracked a big chunk off the manifold. I put the stock exhaust on and go riding and about an hour into the ride the lanyard switch takes a...

Well i just installed dual cooling on my ski and waiting for parts currently...flow control valve and adjustable flow valves to fine tune cooling. My q is...how do you know when you have achieved correct temp. can I stick a thermometer on the head and try to tune a certain temp? or maybe by...

I just built a SN this year and put a riva red pipe and an A/M waterbox in it. I also ran dual cooling. When I installed the cooling lines I added a water restrictor at the stinger but my box is still cold to the touch after running. The water is 48 degrees, that probably has some to do with...

I just rebuilt my motor from ground up but now im having issues with the starter every once in a while. It will spool up but not crank the engine. I greased everything when I put it back together and I had no problems last year. What could be the problem?

I'm looking for domes for my 701 west coast cylinder head...anybody sell em?

I'm putting my 61x back together and am wondering what I should do for timing? I'm running a west coast head with 30cc domes I believe, riva pipe, and riva cdi. Id like to run 93 octane sometimes and 110 others, what should I set my timing at?
