Exclamation ear shave problems!!!

ok so i did a ear shave and now i cant get the bike to run hardly at all

i have 138 mains
i have 40 pilots
and emgo pods
screws at 3 out
2 shims under the needles

i installed a choke cable while i was at it (it ran fine without it under stock jetting)

when i start it up it takes forever then it sputters bad and i have to have the choke lever pulled back (toward the tank) to get it to run
and as soon as it reves up a bit i have to crack open the throttle to keep her there
i have to rev it up to about 6k or it stalls out and when its there its sputtering the whole time

so i took off the pods and there is fuel inside them and if i run it with out them on it spits fuel out both carbs

i also have some fuel dripping out of the exhaust where the flex pipe is (goat removed)

recent upgrades include
ngk iridiums coolant change
new headlight petcock rebuild
oil change ngk caps
new wires agm battery

am i too lean? rich? different jets?
i am stumped
help please vn750.com

Sure sounds like you are dumping way to much fuel thru your carbs! Just about bet you have fuel in your oil also!!

04-3,200 miles bought July 2011 with 928 miles. Loaded with acessories to many to list here, see my albums for more details! I also make a custom tank bib specific for the 750 if anyone is interested, ck my albums for some pics.

how ? the fuel lines are the same size and i added briggs and stratton filters in them
the only change is the jet size should i go back to the 132 mains that were in there?
take out the shims?

when i got the bike the PO had removed the carb boots and it ran ok until i got some speed and it cut out so i put the boots back on and it ran fine
but i wanted to shave it so i went with the standard stuff as stated on here all over and now it wont run

Carbs are flooded. Pull your spark plugs and turn the engine over. Gas will spray out the holes. Dry off your plugs and reinsert. Pull the Emgo uni pods off and see what happens. I did the ear shave with 142/42 jets and the universal pods I had on were restrictive. Ended going with 150/42 jets and the K&N pods and have NOOOOOOOOOOOOOO problems.

Someone else with the shave exp will chime in here I,m sure. Do not think fuel lines and filters has much to do with fuel coming out of carbs like you describe! Are your plugs wet with fuel? Again I would ck my oil too for fuel.

I do have a set of 152 main sitting here i could try but i thought my138 wouldve been ok. I pulled the pods off and no change. I didnt want to shell out for kn pods but i could if i have too. Why would fuel get in the oil?

To much fuel getting into cylinders, passing rings, kinda screws up lubrication and over fills crank case!

You may also want to recheck your needles and the plastic retainer for them. If their not back in proper position it can cause some issues like what you are discribing. Last possibility is to make sure your floats aren't stuck.

I guess i will have to pull the tank and carbs tomorrow and go over it all again. Should i go to a diff size jet? At about 16 a set id rather not go thru too many and have some sitting around i dont use. Add to that a set of k&n pods is another 40. If i need them

No need to rejet, just go through your carbs again. I ran 142/42 without a problem other than the universal uni pods choking the motor at 5000 rpms.
