I am also running a riva intake mani and spacer plate with CF reeds (on OEM cages)
Take off the spacer plate, (get new shorter screws) and I agree with WAX, get some 33cc domes and better yet :cool2: get a more agressive CDI (Wax's or Advent if you want to keep charging system) or go to MSD-TL.

Yes the dry pipe loves alot of advance down low and then to remove it up top
the only way to do this is with a digital ignition
This will make it hit alot harder down low

A dry pipe like a higher pop off
i run my 48 novis around that figure
i would expect your carburation to be very close with your setup

Solid! Thanks bro... now I just need to install some new crank seals and try it again. I think the new 33cc domes will make a huge difference on my lack of bottom end... especially when I found my 37's were only giving me 150 psi/cyl.

Thanks again... :biggthumpup:

water injection will help a lot too, it will make a big diff. on the type 4 from my experience.

Well folks, I think I've got it now!!!
It idles smoothly, hits well, and is smooth all the way through the throttle.
Filling in that crossover made a TREMENDOUS difference!
I am now at 115/100/2.3/65g.
Both low and hight screws are 1 turn.

F I N A L L Y :Banane01: :Banane01: :Banane01: :arms: :cheer:

I have to give HUGE thanks to Waxhead, Supertune, and JrMagoos.
I would be kayaking now if it wasn't for those guys! :cool2:

BRAAAAAAAAAAAAAAAAAAP!!!!!


Now all I have to do is find a way to get 40 lbs out of my hull... :banghead:

pull the 125 high down to about 105
increase the low to a 120
I believe you are way to high on the pop off

Rejetted last night I have a good clean pop at 14-15 on gauge will try the set up tonight. Have to keep this thread going.

you may find you have to go up to about 17
i know it doesnt sound much but its all about percentages
when you are talking about only 15psi then 2 points is a big %

but you should try it first
what are your jet sizes ??

105 m and 120 P 2.3 N/S with 80 gram. I was thinking I may need to go up on pop also my 95 gram should put me up to 17 psi.
Thanks for all your help Wax! :biggthumpup:

Your welcome of course
1 turn out top and bottom
yeah i would go for the 95 myself

Let us know how you get on


Pulling the carbs is nothing but a 5 minute job now and my 12 year old can do it in 7.

The ski ran quite well last night. I had no hesitation but it seemed to bog just off idle. A couple times it bogged and fell on its face in the no wake zone. I am thinking I need to up the pop to 17 remember right now it is at 14-15 psi. I have a 120 P 105 M and a 2.3N/S with 80 gram. This has been a great improvement.
