New Product Idea

Trying to get a feel for level of interest on a new product idea I have before ordering a production-volume run of these.

The Idea: A seamless two-piece bolt on filter adapter

The thought: Get the performance of a press-fit high-end carburetor inlet design (Novi, FS, Thrus, etc.) without needing to spend $1,000+ on a set of carbs. Obviously I'm not saying these will enable your stock SBN to be as good as a bored out aftermarket carb, but it may allow someone like me who is ballin' on a budget to have a better option than what is on the market place today without needing to spend the big bucks on a set of high-end carbs. An intermediate step if you will, between the current offerings and the big guy's carbs.

The benefit: A better flowing intake tract over having countersunk mounting holes in your filter adapter. There is a reason all the high-end carbs have a seamless filter adapter.

How it works: A two-piece design that has a collar that bolts to the carb and then the filter adapter that bolts to the collar from the outside, enabling the inner portion of the adapter to be perfectly seamless.

Cost: $49.99 plus S&H

Would anyone be interested in something like this for their 38, 44, or 46mm SBN carbs?

I understand the concept and hate to be negative about anybody trying to bring something new to this industry so I would need to see data before I passed final judgement.

Here's my thought pattern on these, FWIW;

Am I even in the target market for these? Well, I own two skis, both with bolt on FA adapters. One has Taper bored 38's with adapters bored to match, the other are AM Mikuni 46's.

- Love the design, love the vision, great looking product, reasonably priced for the manufacturing involved.
- Too many parts? I like to K.I.S.S., (Keep It Simple Stupid). I like my ski's simple and reliable so adding parts that can either come loose or seize in place to never be removed again, is probably not a selling point for me.
- Performance gains? I would have to see data for this point or hear rider feedback. I've never considered the bolt on adapters that offensive so I would have to see flow tests results between the two. Even then, how much of an improvement is really going to change my mind? 5%? 10-15% More than 50%? How does improved flow translate to actual performance? Where would I see the improvement, off idle pulls, WOT, over the entire throttle range? How does that translate to how I ride?

For my modded 38's, I think I would be through the adapter wall and into the mounting base by the time I bored them out to match the throat size so those are out.

My 46's could actually be the ideal candidate for a set of these. They feed an SS865 and it could be argued that they are on the small side and could benefit from increased airflow. Lots of people run way bigger and more expensive carbs on this engine package but I'm in the same category as you and many others with the baller on a budget comment so, if the gains are actually there, I'm probably willing to give them a try on this setup.

I like the idea, like has been said I doubt they make much difference in flow rate, but I've seen more money spent on less effective stuff lol. What I bet you could argue is that the resulting more laminar flow through your carb improves carburetion and makes tuning easier/more consistent. TBH I would get rid of the bottom piece and just bottom out the SHCS's into the top of the carb, then counterbore the bottom of the top piece to drop over the socket heads and set screw to the side of them.

How bout making a plug to go in the current adapters that covers the bolts and matches the curve of the adapter? They could be rubber and press in or even plastic. Just need to make sure they can’t pop loose. Seems a bit simpler with same basic gains I would think.

I've never been a fan of AM flame arrestors to begin with, at least for freestyle. I don't need a big funnel/sponge sitting on top of my carbs just begging for water to pour down them.

I had that thought as well but then thought, if you make them tight enough to not pop out and flush enough to have the same effect, they will be a pita to get out when you need to

Good idea. what your doing has been done for for 30+ years just a different way. I like your thoughts. Protec did it and many others. The horns are still popular in ski lites racing. OP’s also where similar. 38,44, 46. Available for all

If you noticed I shorted up the Protecs. Both the 38’s and 44’s. However saying that most racers especially overseas use those horn versions. There are at least 3 companies making those. Funny they came out in late 80’s by Jetlyne. The Protecs are still available all over.

I appreciate the feedback everyone. @Jcary85 I had thought of that as well, but to @te4250 point, that seems as though it'd be at high risk for popping off and then being ingested into the engine.

@MTRHEAD thanks for sharing those. I had searched around to see if something similar was in the market today and didn't find anything quite like what I am proposing, but it looks like Protec has in fact done something similar at one point.

Thanks for the feedback @OCD Solutions I agree, some flow data would be helpful here to prove or disprove the effectiveness. For my next step, I plan to prototype a set and put them on the flowbench and take comparative measurements.

you cant take the pressed in bell off AM carbs , so why would the adaptor ever need to come off? if I thought it would make any difference at all in performance, i'd tape it up and fill it with JB weld or silicone, before i spent money

Back when I raced proam stock in 04’. with an sxr I filled the top of the screw holes on RD horns with JB weld too. Lol no idea if it helped I just did everything I could think of.

Protec did this design. Do you know the early riva red ones were worth 60 rpm over a set of new ada style. The sharp edge on the top of adapter reduces flow. the riva had a rounded edge and it made more power. Dont believe me then try it

I would be interested in trying a velocity stack with more of a bell shape to it like you find on cars and motorcycles, or the old westcoast stacks.
