Carb linkage gap - Novi Tech 48's

[BrightE's]

I picked up a pair of 2 year old Novi Tech 48's and I'm happy with the carbs as they arrived, but when I dropped them onto a ported Riva intake mani I plan to use the butterfly shafts where spaced out far too wide for the Novi tech billet linkage to engage.

Is this a manifold tolerance thing, or are these carbs setup for Kawi's or something?

Looks like they were setup up for an R&D Manifold or one with tighter spacing. The RIVA's are pretty wide. You could change couplers to the larger type and make it work.

Thanks BK. Those things don't undergo any kind of torsional flex compared to the billet ones?

I have been running them for over 10 years now. Only replaced 1 color that cracked from over tightening. The Novi Coupler is nice. But for you to run them you would have to replace your shafts. This coupler only cost about $20.00

Replace one of the throttle shafts and then cut the end to the length you need.

No, they are very stiff and the spacer in the middle is sold extra long so you can cut to fit.

I like the clamping ones that JSS sells the best, the set screw ones can be finicky to get exactly synced especially if your throttle shaft has any marks from previous couplers.

Awesome sauce. Thanks for all the advice.

Hey @stagesrt4 , does that thing have set screws or the 'tightening hub' thing?

 

[stagesrt4]

just look at the picture... id say YES



its just too bad you N paul hate guys like me that part out jetski.... LOL

 

[BrightE's]

So which one? Set screws, or hub tightening?... Looks like hub tightening?

 

[stagesrt4]

only set screws are on the aluminum ends... nothing on the rubber area

 

[yamanube]

Those are the set screw style.

*too slow

There are two types. 1. uses setscrews to jam the linkage to the shaft. 2. is a color that is clamped down to the shaft. This is the Set Screw kind.

Hate's a strong word. I'd put it more along the lines of jealous of all the sweet deals you guys find.

Parting jetskis is a dirty job boys.
