Unhappy New Guy, Ear Shave wont start now.

So I bought my 2000 V750 back about three weeks ago (have not had a chance to ride it yet) I changed the oil and was a milky brown color. So I replaced the water pump gasket and that seems to have fixed that issue. My second problem is that I cleaned the carbs while doing this I decided to do an ear shave followed Phil’s Ear Shave Procedure . Now the bike will not start. I talked to a friend of mine and he told me to try some starter fluid when it is cold he has to use it sometimes. So I used the starter fluid and it will start but the engine races and then dies literately one second later. I checked the carbs and sure enough they are getting fuel ( I added seafoam to see if the fuel was the issue and was not). The battery is good I have charged it. So I am at a loss what could be wrong. I have never worked on a motorcycle before and this is becoming more of a headache than I expected. Any thoughts on what might be wrong?

I'm not sure, but does an earshave require you to rejet your carbs? If so, it doesnt sound like that would cause the engine to race. Maybe check your air mixture screws, set them at about 2 - 2 1/2 turns to start with. This sounds like maybe somewhere in the carb cleaning, possible something didnt get put back right, Just bypassing the air filters wouldnt cause your issue.

It does And I rejeted the carbs The carbs are not that complicate. I thought the same thing that I didnt get the carbs back together right so I rechecked them and all looks good according to the maintenance manual. It races only when I use the starter fluid it wont even turn over if I dont. I followed Phill's instructions and I did set the fuel air screw out 2 1/2 turns.

Also, your floats were starting dry im guessing because you cleaned them. I dont know why the newer vn750s do not have a PRIME setting on the fuel tap. Because now you have to crank the engine to get fuel to flow, that might take a while, and if it does fire and run for a few seconds, it is extremely lean which will cause a high idle. Our 1986 has a PRI setting, if you drain the floats, all you have to do is set it to prime, wait 10 seconds and it fires instantly, my 2001 if i drain my bowls for the winter, i have to crank for over a minute sometimes for it fire, where my dads 1986 fires instantly because we can prime it.

another question, Did the bike run before the earshave? Im still leaning towards something going wrong with the cleaning of the carbs, because you did rejet for the earshave.
