With the red pipe make sure that the little water hole is clear underneith the top coolant fitting.

I just thought My old 550sx was a blast to ride. It did have a lot of mods though. It certainly isnt the fastest but they sure are fun.

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...

JB weld!

By no means am i barrel rolling yet but I do know what your talking about. Sometimes when I come off a wake to do a stab if all the conditions are right I end up with the pole striaight in my chest looking down at the ski in flight. Not a good feeling. I think its all about the timing of 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...

your going to get 10,000 different opinions from all kinds of people on this site who have had all different experiences. I've been working on superjet for a while and if I had to put money on your problem id say it is your start stop switch. when it dies next time find where your start stop...

I would look into riveting it like a lot of aluminum boats. Welding brings it back to -0 heat treatment. If you do weld I would anneal the entire hull.

I always see motocross bikes for sale with number plates and tons of aftermarket parts and it almost always sais "Never raced". ha.

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...

I once left my twin rule 500's on for like 5 hours and it was fine. Also, I ran a float switch for about an hour a few years ago. It didn't take long for the plastic thing to explode. Plus it needs a lot of room to float up and you will have to have several inches of water in before it turns on.

The fuel will flow around, making you slosh off the side of the ski.

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...

Well to answer everybody's Q's Ill be running 93 ONLY after this little mistake. Also, My timing plate is set to stock or less than 1' advanced. At the time I threw 87 in it and ran it but now that I look back on it, it was pretty ignorant. Thanks for the info supertune, I learn something...

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...
