my bike sputters so i sea foamed her, them put her stands to run her in every gear and she didn't sputter at all, them i got on her and road and it sputtered again like not getting enough fuel, is there a chance i may be pinching a line when someone sits on it or maybe it is getting to much air when rolling, .........any suggestions

 

"THEN"...T-H-E-N

Might have to clean your carbs.

 

it starts sputtering as soon as u sit on it or it just started and wont stop. I was feeling like my engine wasnt getting gas on my F2. For me it was a loose exhaust header. and if you did take off the tank to add sea foam then maybe check the gas tank breather tube. But also when I took out my jets and sprayed them the sputtering was reduced, some of the jets can easily get clogged.

 

sorry for the T-H-E-N well she was on the lift, stood beside her, ran her from first to sixth up to about 120mph and she never sputtered once... took her down rode around the block and she sputtered in higher gears , does not really do it much in first and second, brought her back to the shop, put her back on the lift, ran her again no sputter.. the carbs have been cleaned.... is it possible when someone sits on it a fuel line is being pinched, or maybe when i ride she is getting to much air or not enough.. when she is still and no one on she runs like a champ...????
