Cheers.

Is this a straight swap??? Guessing they are wider. Not sure of any other benefits or problems. Cheers.

mine had bcw needle and tickover was fine. now has bdl and i have 1750 rpm tickover. no leaks or tight cables, tickover screw isn't touching.

here is the info i've found so far http://retrorides.proboards.com/thread/141403 According to my Haynes SU book there are 3 jet sizes in the SU family. 0.09", 0.1" and 0.125". They need to have matching needles. The HIF carb series only uses 0.09" and 0.1" so don't go buying...

i've got exactly the same problem. i've read somewhere that there are a couple of different jet sizes?!?!?!?!?!?!?!?!?. slightly less fuel should drop the revs a bit ??????
only got the sj back on the road today after it sitting for last 4-5 years. so it's all new to me again.
