My problem is similar to https://www.askmehelpdesk.com/electrical-lighting/how-connect-transfer-switch-using-l14-20-generator-l5-30-socket-391704.html but I cannot see what the final resolution was.

Here are my specifics:
I have a Yamaha EF2800I inverter generator (http://www.yamaha-motor.com/outdoor/products/modelspecs/443/0/specs.aspx) with an L530 female output receptacle. My home has a GenTran 3028K (http://www.gen-tran.com/eshop/10Expand.asp?ProductCode=3028K) 30 Amp 8-Circuit Transfer Switch. The transfer switch has an L1430 male inlet on it.

Hooked up to the transfer switch are the following (all 15 amp breakers):
2 fridges
1 pellet stove
1 living room lights circuit
1 hallway lights circuit
(the generator has run all these at the same time off extension cords in the past)

I'd like to use the transfer switch and avoid my extension cord mess, but since I want the low noise rating of the inverter generator, I'm faced with either figuring out how to hook an L530 outlet to an L1430 inlet or spending $3000 on an inverter generator that has the L1430 outlet.

I feel like I'm making too many assumptions here and I need some help.
I *think* I could do the following:
1) buy an L530 male inlet plug
2) remove the L1430 male inlet from the transfer switch box
3) wire nut the red and black wires from the transfer switch together with a third jumper
4) connect the white and green from the transfer switch to the L530 as directed
5) connect the jumper to the third remaining blade on the L530

I know this will not support running my well pump during a power outage. I understand that I'll need to put the L1430 male plug back and buy a bigger generator if I want to do that someday. I'm concerned that the loads will not be split evenly when they get to the transfer switch and are connected to the red and black wires.

Here's what I'm going to try. The transfer switch came with a cord (L1430 male and female). The female end plugs into the transfer switch nicely so I'll leave that as is. The male end does not plug into the generator so I'm going to replace it with a L530 male that does.
To connect the L530 to the cord I'll jump the two hots to the single hot connection on the L530, then ground to green, neutral to silver.

With this set up I'll only be supplying 120 to the house so I will not be able to connect any 120/240 appliances to the transfer switch panel. That's OK since I'll only be running the few things listed above.
