61x intake mani on 62t cases

[Fx1 Love/SJ Love AZ]

I am wondering if I will be able to use my 61x single carb manifold on 62t cases. I ask because I'd prefer to run single carb on the 760 I'm building to save tons of hassle. Otherwise ill be stuck with trying to get dual 44s to work.

I guess I may as well ask ask, will I be able to use my 61x stator and flywheel with the 62t cases. Basically I'm building a 760 I have right now 61x cases and 62t cylinders. I have to get the cases fly cut to fit the 62t cylinder on the 61x cases I have from my 95fx1. To make it easier I'm trading my 61x cases for 62t cases that way everything fits solid. I don't want to have to buy a new stator, flywheel, and cdi. And I also dream ill be able to run single carb but that's just a dream. Thanks for the help. I'd like to get going on putting this motor together.

No but you can buy an aftermarket intake that will do what you want.

I figured as much when I was looking only aftermarket stuff. I'm a rider on a super budget but I like to have fun. I'm now looking for dual carb linkage kits, because I have 2 sbn44s from other 701s I've pulled. I'm not against dual carb it's just that single has been so hassle free for me. Time to learn like a big boy to play with the big boys I guess. I love my 701 I'm stoked I'm building up a 760 for my fx. I really hope I get some local help setting up the fuel lines on the dual carb.

Not a great idea to mix and match carbs to make a dual setup. Your FW and electronics will swap right over. Fuel lines are really no harder on duals though...

I have 2 sbn44s I can use. And I will have a 62t dual intake with adapters for the 44s already. I am going to get the linkage kit because it's only $25. If it was just the little 61x 701 I wouldn't want to run dual carbs but I know this engine can be build into something far be aster than what I'm putting together. I just want to be able to have a solid running 760 and dual carbs will make it a beast. This is going in my fx1. Should I just buy all new jetting to make sure they are both exactly the same?

The carbs you are wanting to use will be fine as long as they have the same designation markings which are stamped on the lower part of the body on the flange mount. It is usually common practice for the carbs to have the same jetting, N/S's, and popoff.

Thanks, that's great info for the budget minded. I feel like I should be able to make a dual carb setup work and should not let it hold me back from swapping my 61x cases for 62t.

Why are you swapping cases?

 

[ProSouth]

What bore are you on? What do you ride?(surf or lake)
There's nothing wrong with a big carb 61x case setup on a 81-83mm bore.
There's quite a few guys on here that run it in the surf and love it.

62t 760 cylinder .5mm over stock bore. 762cc. I like single 44. I may have to get the ATP single manifold either new or used I think it will be worth it. I traded my 61x cases for 62t so I don't have to get the cases fly cut to accept the 62t cylinder that wouldn't fit. I'm considering just buying the cases outright and keeping the 61x to build another 701 with a jetmaniac topend. I got lucky on all the parts I got. Instead of paying for 2 new piston kits I got the 62t cylinder for $20 on stock bore with 2 good pistons that are .5mm over and then was $100 to get it bored and honed .5mm to fit those pistons. I got a 760 out of a 701 for $20. I think it was worth it and I believe it's a 762cc now. Mostly I ride flat water, I chase boats and ride aroun the lake. I don't do tricks going slow I like to play around mid throttle because you get the most air that way on a stock hull. Wide open off wakes, I appreciate a motor that pulls mid to top end stock because bolt ons will make up for bottom end most of the time.

I had a blown up 701, cylinders needed bore and one piston was chewed, doesn't matter cause bigger bore means two bigger piston kits. I got a crank for $150, got the 62t 760 cylinders on stock bore with 2 .5mm over pistons, got the engine bored and honed .5mm over to fit the pistons for $100 and that's all so far. I'm held up on the carb situation. The 62t cases I have now have dual carb manifold with adapters from 44s. I have two sbn44s from two 701s. They both worked on my superjet individually. Worked on my 650 and 701. I need a dual carb linkage kit and some help. Or buy ATP single manifold and run one of my single carbs that I have running very well.

on a 760, run the dual 44's. get stock jetting for a waveblaster2 and start there. may not be correct, but close. someone else could chime in, but i think the engine will be starving without atleast a single 48. i run a single 46 on a 735 and could get more out of dual 38's but, im like you. i like simple fuel efficient single carbs

 

[Fx1 Love/SJ Love AZ]

Yea I don't want to drop $400 on a 48 hahahaha, performance wise it would rip alot harder with duals, but I bet a single 44 will still be friendly on fuel. Just that it's a 760 and needs more than a single carb I suppose. I just don't quite get how to link the fuel lines to eachother... T fittings? And the dual carb linkage.

Depends on what you want. Keith Head use to setup 84MM big bore ported motors on 61X cases with a bored out 46mm carb that would rip your arms off... It all in the setup Grasshopper.

 

[ProSouth]

still not a 44 and was it a modded 46?

 

[Big Kahuna]

He built all kinds of setups on this configuration from Single 44 to a monster 50. Keep in mind, a 61X case can only flow so much... It is more about what you can flow and how, and how much can flow out, and when everything comes together..... "The Perfect Setup" for that size motor, cases and carbs.

 

[ProSouth]

i was assuming he was swapping to a 62t, getting a manifold and running his 44. youre right, unless someone has a setup to guide you, its a guessing game to have it "perfect"

 

[Big Kahuna]

Rick Roy ran 760 cylinders (big bored 61x) on T Cases with Single 44 then Single Modded 44 (48mm bored at bottom, with 44mm butterfly). Just a good package.

^^ who's he?
he could keep his 61x cases and run a wetjet setup atleast. 46 with a reed stuffer. i personally like 61x cases. people around here have been brainwashed and think its needed for even 701's and their so much better but i dont see it. i think i'd switch to 62t at around 760cc, but thats just me

 

[Big Kahuna]

Goes back to depends on what you want out of it. Really fast ski........... T Cases......... But, I have known of a few really fast 61x setups........ back to that word "Setup".
