please, take like reaalllly good care of that, ok?

you have something special!

i recommend finding the service manual, and checking the fuel hose routing in that...

i could be wrong, but im not suspecting a fuel line is the prob. usually if there is 2 fuel lines they "t" together anyways.

maybe check/clean the air filter, maybe replace the spark plugs? does it do the same bogging in nuetral?

does it go Potato, Potato, Potato ? j/k....it has clogged jets, runs good at idle and goose it and it starves.
Have someone do the carbs correctly this time and stay away from whomever just did the work. I wouldnt even go back and have them try and correct it.

That push it hard and it bogs thing could also be caused by improper float height.
When you get on the gas the bike uses the fuel in the float bowls faster than it is refilled so it bogs. With correct float height there is more fuel so the bike runs long enough for the bowl to be replenished.
get a service manual and check all these things:

If float height is correct then check/clean jets and ALL the little passages in the carbs (do not use auto carb cleaner)
Check the fuel lines for pinching/collapse
Check the petcocks for grunge
Check the fuel tank for any loose debris (including rust) if any is found install inline fuel filters. Maybe install some anyway.

Yes, you should have 2 lines; one for #1 and #2 carbs and one for #3 and #4 carbs.

I'm very familiar with that model of bike if you'd like to have it repaired properly.
