you even bother with those freakin metal tab things on the bottom plate of the airbox? I removed mine and TOSSED them. to me, they're only there really to serve the purpose of frustrating you, since they dont really lock the screws down as well as proper tightening will, along with regular checks, or some temporary loctite.

As I stated earlier... this is the first time they have been off the bike since the bike was assembled at the factory... With the exception of one float drain screw all the fasteners were still tight. Consider this a view into a bone stock set of carbs.

Actually I am not claiming to be an expert... Nor trying to put off questions. This has only been an illustration of the disassembly of my carbs. And as the pictures reveal the inspection was necessary. Use of the lock tabs or notduring reassembly at this point is premature. Carb number two was clearly in need of the attention.
I read many threads where people were pulling the carbs first thing...and agree regular tune ups go a long way. Maybe I went in with blinders on. And very few of the threads included pictures... So I am sharing my experience. The fact that I have had the machine since new and rode it for 21 years and consider it the most reliable motorcycle in history hasn*t prevented wear and time from taking its toll.
Others sharing has encouraged me to tear it down and at least inspect the carbs.
By the way if you follow the manual I*m doing it all wrong!

for a 21 year old bike thats never had the carbs off until now, thats pretty good. also proof that proper winiterizing and maintenance when necessary DOES go a long *** way.

Hurricane rider, I think the purpose of the lock tabs is to prevent the screw from dislodging and entering the engine...You could imagine what a mess it could cause if a screw got on top of a piston. I will reuse them.

JR have you downloaded the manual at cbrextreme.com ? if you look on page 4-8 there is an illustration of the main and idle jets as well as the pilot screw.
The manual is available there in the download section.

The carbs are currently soaking in cleaner... to be rinsed in hot water and blown out with compressed air. GUNK carb cleaner is amazing stuff if you have enough to completely submerge the carbs in overnight. The instant they go in you can see the residue dissolving before your eyes.

I know, but I prefer blue locktite over those tabs. less irritating, and does the same thing.
