Does anything have to be done to stock carbs if you go w/Ocean Pro Vortexs

[jarcynvicnchris93]

Do I have to re jet or do anything to my stock carbs if I go w/Ocean Pro Vortexs instead of the stock spark arrestors???? any advice is greatly appreciated

Some adjustment may be needed as the OP breathe more freely. Ken (owner of OP) has said that you may need to open the high speed adj a 1/4-1/2 turn out. BUT, Polaris supplied bigger jets with the vortex arrestors as a performance kit upgrade. Keddano bought a kit that came with them. Now this was all for 38mm Mikuni SBN carbs. If you're talking Keihin carbs, I don't know anything about those.....

On the 38 SBN's the mid jet needs to go up to 102.5's, at least I think it was the mids, Kevin remember what one's we changed?

93, what type of pwc do you have?
If you're making changes to something like a 96 newer domestic, I think you'd have a hard time even measureing the change and doubt you would need to jet.
If it's something like a 92 SL650 with thst ultra restrictive intake, I'd say a re-jet would probably be mandatory.
If it's something in the 95 sl 750 area a simple adjustment will probably do the trick.

Ahhh 95 SLT750
I guess you're going pre-mix since you'd be removing the base plate?
Are you going to remove the chokeplates and go with a primer?
If you go pre-mix, change the intake and remove the plates, it's important to check piston wash.
What are your plans??

it is a 94 SLT 750

I think I am going to leave it oil injected for now. it has already had a primer kit installed. thanks for your help

Here's the link to the OP F/A instructions from Polaris

It included 102.5 Main Jets in the kit to replace the stock ones.
