Hello I have a 93 f2 bike with a 140 main jet and 40 pilot jet with stock needle shimmed with 2 washers. I have acquired 4 dyno jet needles and from research have seen people say use the top clip with no shims, does this mean no extra shims as stock needles have one shim I think? Or no shims/washers at all and straight in with bare needle and clip. Currious to try the dj needles to see if there is a difference.

Any needle clip or washers suggestions welcome

many thanks
