WANTED Main jet extender for Mikuni round head jet.
« on: June 07, 2013, 11:51:14 am »
I was wondering if anyone had a main jet extender to suit Mikuni round head main jet, Mikuni part no is VM38/03.  I have tried all the Australian stockists but nothing in stock, I can either buy it off you or replace it with a new one as soon as I can get one.

What’s it do?


It extends the main jet further down into the bowl, it can be matched to a deeper recess fuel-bowl access plug, I guess in some situations one could be getting fuel cavitation and have a need to get the main jet lower?  I need it because the only alternate needle jets I can get for my OEM Kawa carb are shorter than the stockers so I need an extender to make up the difference.

They are produced, part no's - VM38/09 for hex main jets and VM38/03 for round head mains.

John, did you get one yet,
 is it just a colar or is it threaded because i found a small colar approx 8mm long in my jet box which you are welcome to there is no thread though. If you want dimensions to see if its suitable i can run the vernier over it.

Thanks Brett, it has a male thread on one end and a female on the other, both matching the main jet thread.
