I would like to remove the airbox on an 04 cherry Bonnie I just bought. I see several vendors selling a airbox removal kit. What is the opinion of this forum on the best to buy?

The best is, of course, the one I spent a lot of hard earned dollars to purchase. :-D Same for oil and filters :-D

Some would say the absolute best is the avenue of the least dollars...this would be cutting out a large portion of the airbox and purchasing K&N cone filters to install + a filter for the crankcase breather hose + a cheap aluminum turnbuckle from your local hardware store for a carb brace. There are directions available for doing this job.

Either way, you will need to rejet and setup the carbs for proper air/fuel ratio. The kits come with jets that are close for your particular bike with the aftermarket silencers you have installed. You have installed more free flowing silencers, I hope. If not, forget about removing the airbox until you get the more open mufflers--would be a waste of money, IMHO. Once you have the bike close to the right jetting, I recommend a dyno run with EGA to get the air/fuel mixture correct for all three carb circuits (pilot jets, needles, main jets).

Redbird Johnson is right! (lame Blazing Saddles reference)

Most run in the same price range if purchased as a full kit (NARK/FREAK) and of course go as low as doing it yourself which there are some fine examples of on these forums. The DIYs seem to run about $50-$100 pending what you have already.

But the comment on the exhausts is spot on, you can make the lungs better, but if your choking at the other end. What comes in must come out, in with the good air out with the bad.

I'm spent.

I did the Bella Corsa kit as my dealings with Mike has been "A#1 rated" and he has supported me in many of my questions both here and one on one.

I have Staintune with the baffles removed. I bought the bike Monday. The guy had been riding it with the baffles in the Staintune and when I acted surprised he smirked like he may be a quiet is better rider. His other ride was a Burgman. :-D

I too am getting a removal kit soon and have noticed that the New Bonneville.com kit has a carb brace whereas the Bellacorse one requires a separate purchase. Am I wrong on this? If not, I'd say go with the NB one. If so, then they're probably quite similar.

My Bella Corsa kit came with the carb brace (as shown)

I have the British Customs one on my bike. Great stuff. Can't go wrong with New Bonneville or Bella Corse. It's kinda hard to get additional jets from BC, while Bella Corse has a great deal for swaping out jets until you get it tuned right.

Would someone be willing to sell me their 'removed' airbox for cutting up? I have tried asking in the UK RAT forum but no takers. Logistics would be easier if the 'box is in the UK, but have PayPal so I should be able to make a payment to anyone in the US or elsewhere.

Also what mains for Thruxton / TORs once the pod filters are fitted? 138 as per Jenks?

I've been searching, but can't find any threads about modifying the stock airbox. If anyone can provide a quick link I'd sure appreciate it. Also, has anyone ever encountered any sort of problems (intake or otherwise) after the modifications?
