Nessism, sorry if this sounds harsh, but I worked for a shop that did good work that was made to last. The owner was quite "retentive": he had Ducati 748 and always had 996s, turbo R-1s and 1500cc Kaw drag bikes coming in. He mostly worked on the late model bikes because I love the older bikes. I know exactly what these old carbs are like. We did hundreds of these carbs per season, and the owners came back for.... tires and stators and oil changes because the carbs worked so well.
Actually, I've been on GSResources for over 10 years. Newbies are going into their carbs 2 or 3 times because they think dipping is "magical" and will fix everything, when instead they should be concentrating on precision surfaces, all of which are removable or accessible. In cleaning industrial piping, there is CIP and COP, clean in place & clean out of place. COP is full disassembly. If you have a stable, closed system, then it can be cleaned in place with pressure, and chemicals (along with heat in food applications). The passages are not precision, and cleaning this way will remove particles that can cause problems. The precision surfaces are on the ends of the passages and they regulate the fuel and/or air that passes. If you have a bad fuel tee, you will see it (so use JB weld, kiddingggggggggggggggggg). The fuel tees are very well made and deterioration has not often been a problem. The only o-ring that is consistently bad is the CV needle seat, along with the plug above the pilot jet. Diaphrams are the most important rubber to inspect.
THERE IS NO DOUBT that replacing all the parts is good, but how often should you do it (or, can afford it)? Once a year? After all, they are deteriorating. I submit for your approval the radical evidence that most racks are good as they are so newbies can concentrate on the precision surfaces.
I can appreciate a completely new carb system, after all, I bought my GS1000E new in 1980. It has over 110,000 miles on it and has been from Florida to Washington State. I still trust my almost 30 year old carbs just as they are, still taking 1000 mile trips with them. I appreciate complete rebuilds for those that can afford them and know what they are doing, but I think newbies need to know that most carbs can run like new without it IF you do a good job and renew the precision surfaces.
