How big can I go with the stock cylinder? How much does a 333 kit cost? What is involved with the 333 kit? Whould I need to change anything else?

Thankx

A most excellent article.

The one thing I would point out is that getting the air box opened up goes hand in hand with the pipe.

Those three things are all bolt on and you never have to touch the internals of the engine.

Air flow intake, open the air box and use the K&N, flow, the larger duct of the 350X, available at your honda dealer for $15, and exhaust.

TOPCAT, the 350x tube you're talking about.It's the one between the airbox and carb right? I called my favorite honda dealer yesterday and the guy said he found two tubes of some sort.One he said was 15 bucks and the other was 40 $$.I'll probably go there saturday morning to look at the microfiche.
Do you know the stock main jet size on the 300 ex?

Thanks,
scott

I looked at my air tube for my 2000 300ex. There is a small tube running to a clearish plastic container thing. I noticed my friend who has a 97 doesn't have this little tube. Please help me figure out what it is.
