fuel delivery problems

[ZKDX]

hey guys (and gals)...kdx has been running fine until this weekend....i was riding around my track and through some fields...everytime i went through my whoops or across the bumpy field anything past have throttle and it felt like someone was cutting my gas off. Tank is full (i did check that :laugh: ) Is this a main jetting problem. I'm almost positive i drove it since my last jetting change (went to a 310 main). I took carb apart checking for dirt--none found--drove it again..still did it but not nearly as bad?...any thoughts?

310 main?

Maybe your float is set too low?

Clogged fuel line?

Clogged gas cap or breather tube?

 

Braahp - the older Mikuni carbed bikes had a different # system for the jets.

Thanks Dave......I have learned something today.

The reason the Mikuni numbering varies by so much is due to the hex head jets being numbered by flow and the older round head VM carb jets being numbered by inner diameter in millimeters.

 

[Braahp]

Double thanks Rich. I have learned 2 things today.
