Re: Octane's Fast and Furious Carb Cleaning

[Sidecar Bob]

They use the same procedure to remove the pressed in jets in CX500 carbs except with a #4-40 screw (fortunately I haven't needed to do that because mine have all been later models with screw in jets).
As I understand it the part that you cut the threads in is the larger bore that leads to the actual (much smaller) jet opening so cutting the threads does not have any effect on the way it works.

I couldn't count the number of times people have spent a lot of effort trying to clean their carbs without pulling those jets before finally taking them out and finding the cavity behind them full of garbage that was causing their CXs to run poorly. I can't imagine it would be much different in any other carbs....

... so I'm not going to remove the press-in jets. Once it's all back together I'll use a heavy dose of Berryman's B12 to clear out (dissolve?) any residue.

Good luck with that approach!
If I were you,
I'd take the advice from the guys who have been down this road before and remove the jets and COMPLETELY clean the carbs.

Sometime within the past year or two, maybe more, a person mentioned blasting pressurized air into their engine's fuel pump inlet hose barb fitting after discovering their fuel filter wasn't filtering fuel, and contaminants had passed through the fuel pump and clogged all 4 carburetors' individual float valve seat filter screens.

Although that same person may have lucked out and not damaged the internal components of that same fuel pump, there is no discussion ( of course) in Octane's ShopTalk tutorial that would caution against injuring a fuel pump with aerosol brake spray and high pressure air blast, too.

hmmmm. I wondered how badly a good fuel pump's check valves (inlet and outlet) would fare , but never thought about removing the top cover on my engine's fuel pump until last summer to examine,"what's under there?".
note the fine wire compression springs and composite inlet (brown) and outlet (black) check valves.

This fuel pump (installed new in 2013) hadn't been abused and was operating very well. The only concern I had was the slightly deformed oring surrounding the outlet valve retaining bracket. I successfully coaxed it back into its proper position.

There was a video example of a bike that may have suffered an internal fuel pump check valve/s, springs malfunction, as suggested by watching gasoline and air pulsing to and fro through clear fuel hose as the engine was running... the topic eventually ended with no mention of a resolution.
