701 jetting

[whennotsailing]

found one post regarding this, so would like to confirm.... I am going from a 6m6 to a 61x and need all carb settings and proper jetting info for the trade, running a 44mm mikuni. Keeping stock exhaust (for now...)

Please advise.

ok, found out the nozzles are 135 and 115, now just need to know needle, seat, & spring... anyone?

 

[Mike W]

Stock will be 1.5 needle and seat. Not sure on the spring.

 

[Flat Brapp]

i think it was like a 65G. NOT sure though.

 

[whennotsailing]

anyone else confirm?

 

[Mike W]

This is the Riva part number for the stock spring: 6R7-14253-00-00
Give Riva a call tomorrow and see what spring it is. I bet it is a 95gm or 115gm.

For a stock superjet with stock exhaust just use the 65gram shiny silver spring.
Matters not if you have intake or oem flame arrestor with box.

Very light pop on these stock carbs.

27-35 lb pressure will be fine.

I run 95 gram on my stock extra boat.

65g spring
1.5 Needle/seat

135 high
120 low

44sbn

any idea what the stockl 650 carb has in it for spring and needle and set? I guess im just trying to figure what all I have to switch over, thus far it is only the 120 jet for a 135...

 

[dajnglst]

It will be the same 1.5 needle seat with 65 gram shiny silver spring.

Low pop stock.

 

[whennotsailing]

how about rough idea of how many turns on the needles?

also, on the smaller jet I don't see numbers, how do I know what size it is?

I am ready for a test fire, got the engine swapped over today... Now if I can just find an affordable pipe, then I can do this all over again.

Jet size should be stamped on the end of the jet.

According to the Clymers shop manual, the sotck jet sizes for a 701 is:

Pilot: 115
High: 135 (edited from 130 on June 22. 130 is incorrect, I read the manual wrong)

Low speed screw: 1 7/8 plus or minus a 1/4 turn
High speed screw: 1 5/8 plus or minus a 1/4 turn

Idle Speed: 1250

Unfortunately it doesn't make any mention of N/S size, spring, or pop-off pressure

Pretty sure clymers is wrong on the main jet. Pretty sure it's 135.

 

[Super Dee]

Pretty sure clymers is wrong on the main jet. Pretty sure it's 135.

You are absolutely RIGHT!! I apologize. I was dead wrong. I went back to check the manual and found that I read it wrong. I'm such a dumb a$$. I don't know how I got 130 in my head while I was typing.

Thanks for the correction the main jet as it states in Clymers is 135.
