NC35 Carb Tray, Tyga Air Cover and Other Asst. Air/Carb ?s

[Cru Jones]

So, I just swapped out the air filter cover to the Tyga one and was going to fit the HRC carb tray I have as well, but saw no point with the stock NC35 setup. For the NC30 the tray makes perfect sense because it actually directs air into the carbs (albeit indirectly) due to the NC30 HRC setup requiring the bit in between the carbs to be drilled out. For the NC35 I see little point in it if you keep that bit in between the carbs stock and leave in the rubber flap deal. My question is has anyone drilled out their NC35 carb thingy and removed the rubber flap (as well as have a bigger airbox)? I don't really want to be the guinea pig because this is my commuter/fun bike and can't really afford to do that amount of work only to find out it runs like piss w/out a bunch of other stuff being done as well.

In my experience the carb tray cools the carbs. It is not related to ram air.

I think its main design is that, but with the drilled holes in the carb bracket thingy, it cant' also help but direct air into the carbs as well.

The carbs don't need air directing at them. The engine is well capable of sucking in the air it needs and this is what some people seem to get hung up about.

Whatever you do, you cannot really ram any more air down the engines throat than it can breathe. Basic ram air is all about creating a nice and dense pool of still air to breathe and removing the flaps, drilling holes and so on creates turbulence.

To add - most people try and give the carbs the full beans - but nothing is done with the heads, the intake and any proper tuning which is where the improvements come. No point making the engine have so much more air to breathe if it cannot take it in and burn it.

I think that drilling the carb bracket is purely to save weight, not to get more air in. There's no shortage of air able to get into the nc30 hrc carbs!

The carb tray was never offered by honda for the rvf race kit setup. I've learnt through this forum over the years that it's best to use ALL of the kit parts not just some of them (particularly when it comes to carbs/induction).

Best to stick with how honda intended it to be (including non-drilled carb bracket), just follow the hrc kit manual.
