Opening up airbox?

We're happy to have something that runs and looks better than when we got it. If performance increases at the same time, especially over stock, that's gravy. Usually it's only in one or two categories and not overall. At least we haven't given then up for scrap. We all need some kind of hobby.

I did not understand your post, and I still don't. If you "cut your teeth" on KZ650 and KZ750 bikes and know what their airboxes look like you should have understood that everything I stated in my posting is completely true and that I was giving good advise. Even though everything I stated was absolutely true you stated that my posting was BS and added the remark that "More of the unknowing misleading the uninformed." I truly do not understand why you would call my posting BS and attack me when all the things I stated are true.

I had stated 3 things and all 3 are absolutely true -

1. Drilling holes in the airbox would permit unfiltered air along with grit etc. to enter the carbs.
2. If he wanted to permit more air to pass through the filter he could modify the cap and its tube, but he would be wise to do that on a spare cap in case it hurt performance.
3. CV carbs are very sensitive to changes in airflow.

So no, I do not understand your posting since it is bogus. I pointed that out because anyone reading your post might be confused. It doesn't matter if you consider my pointing that out to be getting on my "high horse" or believe I have a "my way or the highway" attitude. The facts are the facts whether you want to accept them or not. If you still believe any of the statements I made to be BS PLEASE explain where I am wrong. Again, the facts are the facts, so if you have more accurate information please post it rather than simply making nasty comments. Ed

Much better things to spend money on. I'm all for modifying, but if you want performance, a set of used cams, and a big bore kit isn't much more money than a dynojet kit and fancy k and n.

Real answer, if it runs fine and you have other things to focus on, do that first, stiffen the suspension up so you can rip into corners and enjoy backroads riding.

People are way too quick to dismiss stock carburetion setups on cars, bikes trucks etc. I have an 11 second small block camaro with a $50 quadrajet on it.

If you read the posts by undiablo, GPzMOD750, wrenchmonkey and JaFlo they point out it is all in the design of the airbox. Being the way the factory did it when the machine was originally produced or modified later on. Your claims are true to a certain extent, they are not absolute as you say they are. Maybe you didn't know all the facts I have just pointed out?
