Hi all,

Trying to get a bit of advice,
Just put a mikuni 26mm carb knockoff on the bike,, deleted the emissions such as closing off the egr pulling the air box that evap can under the seat as well as the lines connecting the egr to everything. I have the vent hose for the gas tank and the crank case filtered and ziptied up.

I've had it started twice since. Once just to test it before I closed off the egr, and the second time after everything was put backon. It seemed to be smoking a bit when I had it started little whispery white smoke from by the motor. Wasn't able to track it down right off. I'm wondering if it was running rich that's why I got the smoke? Hopefully othing internal went wrong.

I haven't been able to get it to start since.

I have spark I have fuel i have air

When I pull the filter and put my hand over the intake it sucks my and and I get fuel on my hand as well. I have the carb air fuel screw 1.5 turns out. Could the jets be the problem.

I'm definitely lost on this one. I almost want to put the old carb back on and see if I have the same issues.

The only 2 things I have not done is swapped out the battery for a new one this one is junk, came dead and needs a jump pack. Waiting on payday to get one. As well as it's the original spark plug.
