    Howdy all, well all my work thus far is coming to fruition. I have cleaned the dickens out of my carbs and replaced all necessary gaskets, seals, jets, and valves. I have run into a couple small speed bumps however, as my carb slide diaphragms aren't quite sliding together. They have all been cleaned and are making sufficient air movement but the speed at which they fall are different. I understand lubrication is hardly an option but I was considering putting some fuel around them to reduce friction. Mind you these carbs haven't seen action in over 13 years. Aside from this, upon reassembly, I seem to have forgotten where the clips and retainers go on top of the carb hats. Although it may seem straightforward enough I really would rather be totally sure before placing everything back together, so if anyone has a reference image for some mikuni carbs fully assembled that I could look at that would be sufficient.

    Another (albeit non-related) issue I have is my coolant/radiator. I did a flush with water and did so until the drain ports ran clear but my fill gauge is incredibly difficult to see through and I cannot get an accurate measurement as to how much coolant is in the bike. I'd be willing to dump the coolant I have now in favor of having a specific measurement of optimal coolant capacity. This of course would be temporary as measuring loss on coolant over a period of time (to any degree of accuracy) is impossible.

    As always any and all suggestions and feedback are welcome.

    Cheers,

    The slide bores should be polished with 1500 grit finishing paper to ensure that the slides drop freely (do not polish the slides themselves. They can be rag-cleaned with a solvent though). Any slowness of the slides when the hats are on will be due to either apoor fit in the slide bore, or a restricted air passage. If one is falling faster than the others you should hold the diaphragm up to a strong light and look for pinholes or tears. Any that you find can be fixed with liquid electrical tape.
