I will not say with 100% certainty that the ported intakes for the CNS from pirate cause both of these carbs to break in exactly the same place a couple days after installing them on two different intakes, on two different bikes, but I think it is highly coincidental.
I'm not trying to badmouth them at all because they are a great company. I think that maybe this is either a fluke thing that happened with my carbs because they had been tightened down so much on the regular intakes using the white collars that come with them, or maybe it's because they are relatively new intakes, so there hasn't been that much customer feedback on them yet. Either way I think I should share my experience and let others know that there is at least a possibility this may happen. Like I said, I just think it is too coincidental to dismiss.
It's a shame because the intakes fit great. I think that the metal of these carbs is so weak that they are just prone to breakage from vibration- also prone to vibrating off the stock intakes completely. The mouth of the carb (if that is what you call it?) is relatively short and very wide.... and the carb is heavy so that doesn't help either.
Take a look at where they broke and notice the same pattern. My guess is that the white collar that comes wit them helps protect the carb from the direct vibration. When you remove that collar and you put all of the force (and vibration) directly on the "mouth" of the carb on that wide intake... I just think the vibration is too much for it to handle.
Please take this FWIW... and I'd appreciate any other hypothesis as to why they both failed like this and maybe something that could be done to lessen the likelihood of it happening?
These carbs aren't cheap and I have a whole box of broken carbs and parts possibly for sale, but that is another thread. I really like the extra torque they provide, but I would find myself adjusting the carb almost every ride.
