It would be so cool if someone dynoed both carbs of same size. It does sounds better and look better too. Very interesting product. Im still trying to decide between ported kehin (by duncan) or smartcarbs.

[@GuessWhoGurr]

I can’t imagine having the same power gain from just bumping up a size in Keihins.. if I ever get the chance I would really like to dyno my banshee now. Probably is still pretty weak but just curious!

[@Monkeigh7]

There’s a noticeable performance gains. But idk if the top end is coming from the SmartCarbs themselves or from the carbs being 4mm bigger. I would like to see an apples to apples comparison for the same size. I don’t doubt the the smartcarbs but I want see the minute details. Nice video and bike!

[@GuessWhoGurr]

Thanks man, I will get a good comparison video soon with multiple carbs.

[@2006BansheeRider]

Sounds sweet! Seems like it pulls harder on the bottom end and its a lot smoother going through the whole gear

[@GuessWhoGurr]

It does!

[@christopherortega5867]

I'll buy ur old carbs....

[@GuessWhoGurr]

I was thinking about giving them away!

[@ls3power]

Rolling good! What sprockets u running?

[@GuessWhoGurr]

I’ve never checked lol I am going to find out and then go up a couple teeth in the back though, see how that works out. I’m sure I’ll have a video on it!

[@deckpogi2680]

been thinking whether to go SmartCarb with 38mm or the Billetron Pro air 38mm doing a 443cc 7mm+ stroker so quite torn between them hahaha

[@GuessWhoGurr]

They’re both great carbs just boils down to how much money you want to spend 😁 40mm wouldn’t be too big would it for that size of motor??

[@deckpogi2680]

@@GuessWhoGurr looking on the 38mm as many other users stated that the 38mm is the right balance and love for the banshee engine that let it rips out full hearted beat. but the funds won't be a problem for me its just I am quite torn between which to get hahaaha

[@yourstruly_johnny5843]

What manifold are u running with these ... Built in crossover style?

[@GuessWhoGurr]

No was was running one with a rubber hose as the transfer port

[@wangchung5028]

You can hear the difference!💪💪

[@GuessWhoGurr]

All day long, those carbs are the future

[@xavierbatti7617]

Can you ride it with the air box?

[@GuessWhoGurr]

I'm sure you could with some modifications

[@karl6823]

Damnnnnn where can i get one!!!

[@GuessWhoGurr]

There is a link in the description! Super friendly people if you call in!

[@user-rn8jo2ln1d]

this is good content

[@GuessWhoGurr]

thanks friend!!

[@motorheadproductions865]

Hey how much of a difference would there be if you ran a single smart carb instead of 2 with a 2 to 1 custom intake?

[@GuessWhoGurr]

I personally have not had any experience with running a single card on a banshee. some people like it, some people say twin engines need twin carbs.

You need attention that bad?

[@GuessWhoGurr]

Huh? You sound so desperate for an online buddy it is sad. Trying to get a rise out of a random guy online when you’re almost 40, I couldn’t think of a better life than yours. Sad sad sad, I’m surprised though after 2.6 million views that there’s only one of you over aged psychos in love with me. You live a sad life jimmy, hope one day you find a purpose.
