 It would be better to get a set of 45s if you can, but the 40 can be made to work....just a lot more testing and tuning.  There won't be a 'book' solution. 

The DHLA45s I got from Dave Bean years ago (Spec 9 variant), spit and popped like mad.  I had the black plastic soft-mount which had a total of 8 o-rings, thackery washers and those solid rubber mounts as well.  All 'by the book'.

My spitting actually stopped when I abandoned the Spec 9 jetting (160 mains), and adopted closer to stock jetting (135 mains).

Every 'spit' or 'pop' blew-out an o-ring and/or upset the linkage unbalancing the carbs.  After years of frustration, I did a hard-mount and never looked back.
