Tonight I replaced the 4) rubber coolant plugs and re-assembled most of the bike so it is ready to re-install the carburetors and once that is done get air filter system re-installed, gas tank, re-configure the wiring since I disconnected a lot to not put stress on the harnesses as I was taking everything apart. I re-filled the coolant (Used Prestone 10yr) and put in 3.5 quarts of Amsoil with a Mobile 1 110a oil filter.... should be able to finish getting it all back together by end of this weekend so I can make sure everything runs right and put it thru a heat cycle or 2 so I can double check coolant and other fluids and once I know everything is good to go and I wont have to tear anything apart again to troubleshoot any potential issues I will do a carb sync. I ended up doing a total re-build on the 4 carbs but did not replace the outer diaphrams, hopefully that does not bite me in the ass but figure as long as everything else is good I don't have to fully remove the carbs to replace the diaphrams if there ends up being an issue with them tho I dont expect to have issues... they were a little bit stretched, it was pretty obvious that these carbs had never been taken off the bike or worked on previously but they did not have any tears or other visible issues and overall the carbs were in really good shape. Only weird thing I ran into considering how well the bike ran was how far off the floats where set from the factory specs in the service manual...maybe my gas mileage will go up now that they are properly set - at least I hope I set them right :-). I installed Ivan's needles and main jets so will be interesting to see how that changes the bike attitude, assuming it will be a fairly subtle change.
