Is your engine ported? What pipe are you running? Obviously porting and the pipe will allow the larger carbs to show bigger benefit than a stock cylinder.

I can comment on the oem 760 vs a/m 44 mikunis. I have ran both on the same engine, in the same ski. The oem 760s I ran larger jetting by one size to get the tune right than with the a/m mikunis. I also did not drill out the return restrictor on the 760 carbs as I did on the a/m carbs. The a/m...

I have had nothing but top notch service from Paul. He's a great dude, knows his stuff, does excellent engine/tuning work and is someone I consider a friend. He's in GA and I'm in NC so about 5 hours. I also love that he is one of the very few engine guys that actually rides. I'll see him next...

https://www.thefoamfactory.com/closedcellfoam/neoprene.html I've used this product here on my superfreak. They have all different thicknesses from 1/8 to 2 in thick. The price is about the same as hydroturf brand however you get a lot more material here.. I used the 1/2 inch and 1 inch on my...

Only real way to know if you need a bore is to measure your cylinder and pistons for wear. Otherwise you're ultimately guessing. If it were me and didn't have access to bore gauges then I'd replace the pistons and rings along with a light hone. But also keep in mind, when you hone the cylinder...

Actually he did in the second paragraph where he addressed the response directly.

Not to mention the cost of said batteries. I fly rc airplanes that use lipos. Most of my planes are edf jets. They use a 6 cell battery at 25v. The edf is a 90mm housing with a 12 blade rotor with a 1900kv motor. That setup at max throttle pushes around 120 amps. The typical battery for that is...

The 62t cylinder really comes to life once you get to 83mm bore. You can also get a .015 thick base gasket which will lower the exhaust port slightly and give you a little extra compression (about 10psi) more which all helps with low end torque. I have a ported 62t cylinder and it runs excellent.

Even the same hull with the same engine, carbs and pipe just with a different pump will act entirely different.

with a top loader style intake grate like the worx 201, youre not going to get rid of the porposing at speed in smooth water. that intake grate pulls the ski into the water to keep the pump hooked up in rough water. its not made for glass or smooth water. if you ride in mostly smooth water, then...

I personally would never put open style air filters like that on any ski other than a purpose built race ski. Only place I see any benefit in those style filters for the extra horsepower and the fact that the riding is around a body course instead of jumping waves and going inverted. Cranks are...

It's only illegal if you get caught haha. Our group will typically get a wake surf boat to throw us a wake. I've always gotten the most height hitting the wave right off the back of the boat. I'll also add that we don't hit the boat wake right off the boat unless we know the owner and they are...

It's something that I think a lot of people don't do is a leakdown before teardown. Once a seal is broken its too late to tell if a leak was present. The 750/800 ignition advance is alldpme through the cdi. Can't rotate the stator to advance timing. Only option is an advance plate for the...

It almost looks like thr front cylinder went lean. The rear piston piston wash looks good.. Typically the rear cylinder goes first in that type situation due to heavier load being closer to the pump. I'd also check the crank while you have it apart. Did you happen to do a leakdown before teardown?

Pulling the trim kills the height

That's exactly what I told you to do is keep the badass and put a smart engine in it haha

Gotta hit the wake right off the back of the boat for maximum send. I also am curious how much water you ingested through the open style air filters. How does it ride compared to the badass other than being shorter? A local guy has a -9 titan. I haven't ridden it yet. He seems to like it as it's...

This is exactly why you have to actually measure the bore after honing to make sure it's not too loose. Had to be super loose in order do that on the first ride after the build.

Those look very nice. I found your thread recently and have considered buying a set. I don't like open style filters especially on a surf or rec style ski because of water getting into the engine. Crankshaft aren't cheap.

My 550 had the ocean pro ride plate on it with a pjs top loader intake grate when I got it. I rode it for a season with it like that.. it porpoised really bad and no amount of weight forward helped. I ended up finding a "shredmaster" intake grate/ride plate combo "surf" version and ran that...
