Hello, I'm looking to begin a new A/M hull build, an I can get my hands on a waverunner 760 64x w/dual 44's with electronics for cheap and wanted to know if this would be worth building or having JetManiac do his magic to get some good bottom end brap? Or should I stick with my 61x an find a 62t case an dual 38's and go that rout? Any help/info would be appreciated... thanks
Custom/Hybrid Waverunner 760 motor for freestyle brap??

I would send that 760 to nuklear on here. I heard he builds some hard hitting 760s

They are not ideal but there are some wizards out there that can get some serious power out of them. They won't have the punch of a 62T/61X setup but they will have a much longer, smoother and predictable power band. While I really like mine in the surf, I certainly wouldn't consider one if I was building a dedicated freestyle ski. In that case I would stick with the 61X cylinder.
Now, that 64x does have dual carb pulse lines and would be a great platform on which to build up a stock stroke bigbore...

Great info thanks... So what does a stock stroke bigbore entitle? An what exactly does that mean in motor size, CC's, and dollar wise, sorry for the noob question.

I almost wish I hadn't mentioned the bigbore now. Way too easy to turn a good little build into a monster that costs way too much and isn't really any funner.
Depending on which aftermarket hull you decide to go with, you may not need to drop a ton of money into the motor anyway. I think the Jetmaniac engine is a great place to start and I would stick with your current 61X setup and discuss different power options with Chris. He can put together a fantastic engine package for less than a third of what a Stock stroke big bore would cost and you won't have to build up everything else around it.
P.S. That's my mature and responsible advice anyways. I of course have no idea what your budget or riding style is like so take it for what it's worth. I just know that most guys get caught up in the bigger is better thing and forget that sometimes less is more. I have also seen many guys show up on $2-3K skis and absolutely dominate guys with $20-30K into theirs.

Yeah. Great guy. Im willing to try him out since he is close by and looks like somebody who will stand by his products. Plus if i ever need the help its a short drive and he seems like a person who will always help and then some. To me thats worth the money
Ive always been told to go with the dual 701 versus the 760 motor but for me im still a ways on pulling the trigger on either engine. I have time to do research and maybe test out some engines. ANd like OCD said your setup may not require a huge and expensive motor. A lot of people on budgets just get the 701, dual carbs or a single monster, head, and pipe. Maybe a few little things added on top and a better impellor to give the bottom end you want.
OK. So outta the hole X everyone says go with the 62t/61x... But, I have many friends local that tell me a 64x can be setup for freestyle? I'm tired of hearing both... An really Bout to forget about my build till I can see better. So thanks to everyone thAt chimed I'm an peace to my cowboy keyboard peeps. I really think a 760 can be boned into a freestyle motor

Nobody said it couldn't be done. There's just way more 760's out there that weren't done right and give the setup a bad name. If you have access to a guy who knows the tricks then I am sure you can get solid setup that will do what you want.
Good luck with your build.

the port timing is what is the main difference. 760 cylinder's are 62T cylinders with bigger sleeves but identicle port timing. the objet is to make the 760 64x identicle to 61x port timing. I ran into this dilemma as I recently blew my 726 61x/61x, I decided to go with a bored 61x cylinder up to 84mm(760) with freestyle porting. if I ever want more bore size ss power, just have it resleeved with bb sleeves. I am in modesto as well btw and we should for sure hook up and ride, maybe even build together, you are more than welcome to ride my setup once ive rebuilt it and check it out yourself. I also have 82.5(726) 61x cylinders with mild porting you could buy and bore to 760. pm me and we can swap motors, im a noob too and a young rider, so we can learn together lol. always looking for a riding buddy too.

61X bored to 84mm sleeves get pretty thin.

group k says you can max out at 84.5mm and 84mm is common 61x bu the thinnest without egging out quicker than normal.
When I was planning out my motor build I was originally going to resleeve a 61x cylinder but decided to try the "budget big bore" option. I ended up sending a set of 64x cylinders to nuklear. He decked the bottom to lower the port timing, ported them and bored to 85mm. He does great work and I have my hopes up but haven't had a chance to run it yet.

I have heard of doing that to 64x but never heard the ride report. if you don't mind me asking what did that cost you, from sending off to nuclear too pistons

I have heard that option as well but I think you can get good power out of them even without decking them. Mine has great bottom end punch already but I recently tried a 13/18 Skat swirl in my 140mm Mag pump and the thing was unrideable in the surf. It had way too much power right off the start and was way too unpredictable. It was awesome on flatwater though and I was actually pretty impressed considering I am used to riding an SS865. I've tried a few different pump/impeller combos in it now and can make it wild or mild as needed.
Considering I only have $1200 into the entire engine, including carbs, I say it's pretty damn good setup. If I dropped it in a 65lb hull, I have no doubt it could do way more than I'm interested in doing. However, in anything other than a purpose built, lightweight hull, it's going to fall short and leave me wanting should my interest turn toward freestyle riding.
I would really like to talk to one of these 760 guru's and have them look at my cylinder. I am pretty sure it hasn't been decked but I do have the port specs and something isn't right for a 62T. The height specs on the exhaust ports are almost identical to a 61X. It's also been pointed out that the sleeves have been replaced so I don't know exactly what magic has been worked but I do know it works well. All I was told was that it was race ported by Todd Lachance of TLR Racing.
Here's a link to my original build thread. There's some engine pics posted but nothing really detailed regarding porting. Since it's the Wife's ski now, I really have to keep it tamed down but I would love to see how it would perform with a bigger intake and carbs.

This is not correct. (Exhaust) port timing is different between the 760 and 62T 701 cylinders.
