Was super careful this time around with these floats and am feeling good about it working properly this time around since I also found a thread earlier today where @V7Goose reset his floats a while back and used .034 or approx 8.4mm for his float heights and his write-up pretty much confirmed what I needed to change and how to measure (I think the 1st time I also used the skinnier float for the measurements not realizing that they sit lower than the fatter floats so I was originally probably closer to 9.5mm height which was No Bueno. Not sure how I missed seeing it previously since I searched a while back and didnt find it then but I sure as hell wont forget the lesson I learned doing it wrong the 1st time! Would have had to pull carbs back out anyway cause I realized after doing some testing that 2 of my 4 vacuum slide diaphragms didn't have a good air seal cause they shrunk some on outside diameter and are too deformed for me to make them work...figured out a neat trick to test them after install using air compressor to confirm they are properly seated. Anyway, set all the float heights at 8mm (using the larger float side on all 4 to measure height) and also held the carbs at approx 75 degree angle while measuring to ensure that the needle plunger was not being depressed at all since it doesn't take much pressure to compress them, even at 45 degree angle the weight of the floats will start compressing the plungers & throw the measurement off. Was one of the things V7Goose had in his writeup that made a lot of sense and worked very well. Thank you Goose! Soon as the OEM diaphragms arrive in a week or so I will change them out and then put everything back together so I can re-test. Fingers crossed1 point

Got everything torn back apart last night and removed the carbs. Nothing was obvious regarding the fuel dumping out the overflow, it was the rear left cylinder #1, you could see a little fuel inside the intake boot mounted on the cylinder and the top of the piston was also wet when I removed the spark plug. No other cylinder pistons had any access moisture in them. Pretty sure it had to be one of the needles/valves not sealing properly that caused this. On side note I do think I set the floats a little too high (or low when carb is upsidown) since factory setting was really far off as other people have previously noted when they checked their float heights (mine were set at 6.0mm from factory and spec is 8-9mm). When tab is bent to "raise" the floats to the proper level, when it pushes down on the needle into the valve seat it pushes the needle sideways a little bit and I am guessing that had to be the reason the needle didn't seal correctly so gonna find a happy medium where I can get the floats close the the recommended height with the tab as straight as possible so that hopefully doesn't happen again (I did install new valves/needles/o-rings previously), thinking if I go with 8mm or .0315 it should prevent that and I will be within spec, initially I had set them at 9.0mm or .036 which is on the high end but when re-measured after taking the bowls off again they were all closer to 9.3mm so gonna be more careful this time around resetting them. Another thing was when I previously re-assembled the carbs after re-building them I noticed that my vacuum slide diaphragms had shrunk a little bit which I guess is too be expected being 12yrs old and they were tough to get back into the outer grooves when re-installing the outer diaphragm covers, I used a little dielectric grease on the outer edges of the diaphragms to help them slip into place but when I removed the cover for the Cyl #1 cover I realized that it had pinched the edge a little. So bit the bullet and ordered 4) new OEM slide diaphragms last night which will be here in a week. I know that would not cause the flooding/rich condition.... if anything once running a bad seal on the diaphragm would cause a lean condition but glad I caught that since I would have potentially fixed the flooding issue and then had to pull it all apart again later once I realized the bike wasn't running right since with a vacuum leak I would never have been able to sync up the carbs properly. Honestly if this is the only issue I run into after stripping the bike down as far as I did over the last 4 weeks including tearing off the entire rear end including the swingarm, I will be pretty happy! Once I got her back to running right my last planned upgrades for the winter include removing the front wheel to also replace the bearings/seals on the front wheel (already did the rear and there was VERY little factory grease in them)...same with the swingarm bearings tho I did not replace them, I just cleaned them out and re-packed them properly with Lucas synthetic marine grease as well as all the needle bearings in the suspension linkages. I also recently bought 4) of the Polk 402 speakers & foam baffles that I plan to replace to get a little better sound, maybe down the road I will add an amp under the rear trunk and install a good head unit where the factory cassette player currently is. The only issue on this bike I have never been able to resolve is the fuel sender gauge. Since buying the bike in 2021 the fuel gauge has had 8 blinks.... from my research that pointed to replacing the fuel sender assembly in the gas tank. I replace it in 2021 and the same thing kept happening, thinking I got a factory dud I sent it back and get another new replacement, installed it.... and same thing. I have ohm'ed out all the wiring and done everything else I can think of and never been able to figure out that issue so I have just always reset my trip when I fuel up and keep an eye on it that way but damn its annoying not to have a working fuel gauge even tho I know they are never totally accurate on motorcycles and boats. You know what, now that I think about it even tho I tested all the wiring the one thing I have not done that could cause this if all the components & wiring are good is make sure that the connector that you unplug to remove the gas tank is making a perfect connection when plugged together, think I will remove both of those connectors and direct wire them temporarily to see if somehow there is a bad connection there. See, sometimes talking to yourself gives you light bulb moments! Lol Happy holidays!1 point
