Do you remember what jetting for that needle position
Is it a US Version or European / Oceania
Thinking out loud about Needles and Markets I got the impression that the version being non adjustable being emission laws
regulated and leaner. there is a lot of variables
US bikes were setup leaner and the law prohibited changes.
So if I get it right the designer are designing 2 different objects with different internals
Object A and Object B He has the task to get it working and running on respective markets
Normally he has little interest in matching these between markets
Because very few are going to drill out and adjust needle as a customer in the US
by warranty and legal reasons back then on a new bike.
Not that common either ship bikes between countries then.
I think the designers order was do the setup and test it manufacture and ship.
Perhaps taking the parts from another bike setup
My guess is that the US Bike runs leaner than the other for the same jet.
More Air ( Extra holes ) is no problem if you can adjust Needle and other
But it is dangerous if you cannot adjust
Jan i have an Oceania and Canadian model. They both have the 5lX11 needle and 336YO needle jet.
I have translated the Japanese 4E3 Standard model parts file, the Japanese used for their market and the Euro Standard model, (80/81), with the Adjustable needles, to English. I will post it up when i get home. Haven't got my external HD with me.
This parts manual has the recommended jets for these Jets/needles but the jet sizes are basically the same as the US used. I run 132.5 Main and 130 Air jet
