OK. So here I go. Doing the carbs later today.
AI removed, drilled the airbox, removed 3 snorkels, Unifilter, Sceptre pipes. Oh yeah, and it's Cardinal Red
Going with 135 mains, 45 pilots, stock needles, no shims.
I will report back later. It's raining here today (and I don't have a seat) so there will be no test ride. I am just hoping it will start, then I will take it from there.



FWIW When I first installed the Sceptres on Vera Lynn I used the jets they shipped: 122/48. (and one shim under each needle which where already in place)
I now run her with 1 shim, 125/45, 2 turns, stock air box, oem filter, all the snorkels in place, and oem needles.

When I re-jetted to the 125/45 combo I removed the shims. Ran like crap. Simply adding the shims back fixed her up.

When you changed out your mains did you drop the holder? If the collar was left out the symptoms would be similar to yours.



Oh yeah,

What the heck Redondo Ron's write up

Whatever the case with the mods you have done did, you are gonna have a major flat spot with no shims and oem needles.

To illustrate the flat spot fix here is what Cinnamon Girl had done when I installed the D&D's and pulled the snorkel. K&N filter, stock airbox with primary snorkel removed, and a polaris bellmouth. I had to bring her to this current setup to thwart that beeching flat spot: 130/45 2.25 turns TBS needles, 1 shim
