how do you remove the stock air box, I have removed the pins that hold the air box to the carbs and all bolts (i think) it wiggles around but how do you get it out does it break down into two pieces because there is no room to get it out it seems unless it breaks down HELP!!

 

[Donnie Darko]

so just break the SOB and get new filters that dont require the air box then?

 

[Donnie Darko]

ok Well the air box is gone I had to cut it because even though I took the carbs off it still would not come out because this little nipple piece at the bottom was getting hung up so yeah I cut it !!!!

at any rate why would it make carb tuning a nightmare? would mine be a "short" stroke motor? '89 GSXR 750

Well what about K&N replacements ? they going to make it run totally different as far as fuel mixture, I know on some carbed cycles that you have to keep the float bowls at the same pressure as the "static" air in the air box but the carbs had breather tubes that were vented to the air box and did not have a drain to prevent flooding. BUT on my bike it didnt have any kind of "breather" tube and that would be the only issue that I could see having without the stock air box. Is there something else I should be aware of?

 

[Donnie Darko]

Well a little late for that info but thanks, I dont think it will make that big of a hassle I will just adjust the carbs if needed and that will be the end of it. No bulky air box to worry about

what IF I just put on some Mikuni flat sides ? maybe even some smooth bore?

 

[Donnie Darko]

yes i know the stock ones are CV "constant velocity" BUT I didnt know that Mikuni flatsides where the same as smoothbore thanks for the info now with the flatsides would that resolve the issue with the air box?? or should I just just re jet the stock carbs ?

 

[Donnie Darko]

so where do I fine some of these Flatslides? I have looked on the actual Mikuni website but they dont sell them on there for some reason..I wish someone would have told me that it would have this much of an effect and I wouldnt have hacked pieces of it off...

..my own mistake but where can I find some 34mm flatslides?
