removing the stock airbox '83 (shadow)
J6G1Z:
New larger jets are installed & they are still not enough fuel. :'( I'm getting tired of this drill. Some larger jets are on the way.
A new member joined today that has also experimented with the exhaust, airbox & jetting. He mentioned in his post that two #125 main jets are what is needed.
Do jets come with odd I.D. numbers? I thought they all ended in even numbers.

After a while on the FT, I started drilling the stock 140 main jet; it was faster than driving to the dealer and back, and I knew it would never be used again anyway, so no loss if I messed it up. As far as jet sizes, I think the Keihin jets alternate between 2 and 3 numbers per size, up to a certain point, then jump to 5 or 10 per size.
Are the VT jets interchangeable with FT jets?

Don't know. I would tend to think so, as they both use Keihin carbs.
The DynoJet main jets are a bit taller than the Keihin jets & use a longer needle.
Where does one find accurate drill bits that are suitable for drilling jets?
Thanks

Oups sorry ! I had not seen how was called your version in US.
I was thinking about the FT500.
I see that you have a difficulty finding the good jets, in France I use this : http://www.3as-racing.com/A-35000-gicleur-principal-keihin-kec.aspx#.U9UiAPkYyVI

Here is a source for metric bits in .05mm increments:

The pilot jets I got from my local dealer were longer than the stock FT part, and had no markings other than the size. The mains were stamped AB and the size on the end.
BTW, what have you been paying for jets? My dealer charged me $4.95 plus tax for a main, and $7.64 plus tax for a pilot.
