Hi All, I'm fairly new to the CBF but have covered some decent miles on it. I agree it's too quiet so going to try this mod out this weekend. What is the air box flapper mod?
Cheers

As I understand it ,
In the Air box is a vacuum operated flapper that closes at certain revs to reduce intake  noise for testing .
removing the pipe and blocking it up prevents the valve from closing increasing air flow throughout the range.
Might be tosh but it seems to work for me

Hi,
Reviving this old thread,
I’m interrested in modifying my standard can  instead of buying aftermarket as the laws around here does not allow aftermarket can.

Unfortunately the pics dont show up anymore.
Anyone has the pics of the procedure? And maybe pics of the internals?

If anyone has standard cans for sale cheap (i’m in canada) i would also be interrested

If you click on the photobucket image the photos load up one by one

A plastic hammer on the baffle outlet and smashing it with a large mallet. 10 more finger stinging minutes and hey presto, it broke the weld. Another 5 mins to wiggle the baffle out with stilsons.
I started the bike but to be honest in my garage I could not hear too much difference.
Now I have to retighten the exhaust at the centre box from the baffles being writhed side to side. Plus the otherside to do.

Guys, I'm in the middle of removing the baffles on my standard cans and I've released the ends of both sides using a hole saw and now I'm into trying to snap the inner tack welds off. I've tried the crow bar waggle waggle method and the whack the  thing with a hammer but nothing seems to work. Can you tell me where the tack welds are so I might be able to concentrate my efforts?

Hi, would like to get a fuller sound on my 2007 model, am I right in understanding the original exhaust system comes complete with a catalyst converter?

 How is the running effected if you ditch the original set and does the fueling need to be reset? which aftermarkets offer the best value in terms of price ease of fitting and improvement in sound quality?

 thanks for any feedback!
