Heavens to Murgatroyd Mr Nessium!
Are you so set in your ways you cant even consider an alternate route to the same destination. (clean carb)
Removeing the butterflys is just 8 screws, talk about making a mountain....

You can sit around for hours while your carbs soak, making incorrect blanket statments, and pretending the insides are a mystery.
While I will just put my clean carbs back together actually knowing its right the first time, and use the saved time to go for a ride.

Guess what I belive I am right just as much as you do, but I wont get into a internet tit for tat about it. awww ****, perhaps I just did.:D
 
It is not just 8 screws John as those 8 screws are swagged on the ends.Not easy to get out at all.

JIS phillips head screws. You need to press really hard to get a good bite on the head, and pressing too hard can bend the throttle shaft because it's small diameter and has a slot cut in it. Even knowing this I managed to strip the screws on one carb I was taking apart for parts. Also, in order to remove the butterfly you need to drive out a split roll pin on one end of the shaft which holds on the sync bracket pieces, an assembly which is under spring load (need to count the turns so it can be assembled back the same way). When reassembling, you need to make sure the butterfly disc is properly centered in the carb bore or it won't close properly. The entire business is a pain in the butt. I've done it myself but wouldn't even suggest this to others unless they are very detail oriented.

BTW, Nissan built a bunch of engines in the mid 2000's where the butterfly screws used to work their way loose and get sucked into the combustion chamber. They farted around with loctite and different types of screws but couldn't seem to fix the problem. The proper fix is to swedge the screws after assembly, but this requires special tooling which Nissan didn't want to invest in. An alternate method was to use a laser to melt the screws to the shaft. I mention this because after those screws are removed they are no longer locked to the shaft and could work loose in time, even with loctite. The original screws on GS Mikuni's are physically locked to the shaft and should be left alone unless a know problem exists.

uuummmmmm.....wow. SVsooke and Nessism just let you know 'why' removing those butterfly's is such a problem. I'm guessing you've never actually tried or you wouldn't have made such a statement.
 
Let me say I have done this many times, thats a fact.


I'm talking genericly here, the shaft comes out by drawing the other end with the nut and flats thought the body, theres no need to touch the roll pin. If however your specific carbs need to remove a roll pin (most commonly one of the middle two)thats not hard at all, if you use the proper tools and techniques, ditto the screws.

Also I never said this was for everyone, it was directed at those that understand, or want to.

If your level of skill with tools involves using the wrong ill fitting screwdriver applying excessive force and pressure,not supporting half shafts, and not taking note when you dissassemble things... Then you dont understand, and this not for you!


I am not going to disscuss this any further, right now,it will only get insulting. and tit for tat...
Readers can make their own mind up.
 
We have enough problems trying to get the new guys to do basic stuff properly, let alone trying to outline something with that level of detail orientation. :-\\\

Fixed it for you, Steve.
 
Ok, 8 screws are not that big of a deal,,,, although you will need to use JIS screw drivers for the 8 screws so you don't strip them,,,, I know the JIS screw drivers are kind of expensive but if you are going to screw with the 8 screws than you need to use the JIS screw drivers,,,, not sure if it is worth it or not.... either way....

Does anyone have positive experience with the ultrasonic cleaners,, what kind of solutions can be used in those.....?????
