Stromberg Needles

Due to a few mods to the twinc I am finding that the standard B1Y needles are going a bit lean at times. Does anyone have any suggestions for a needle that is a bit richer higher up?

If you have Dave Bean's catalog, refer to page L23. They indicate B1BT needles for twin cams with mild performance cams. These needles have richer mid/top than B1Y.

Hmm I had heard rumours about B1BT needle profile. Alas for me the B1BT is of the adjustable type and the carbs on my Elan require the non-adjustable type. Looking through the needle data the B1AD is the closest match of the non-adjustable types. I will give this profile a try once the wide band lambda meter I have just ordered arrives.

Thanks for the feedback. I had sent an email to Dave Bean but they could not be bothered to reply.
