Switching 81 SRX carbs to 38 Roundslides, Jetting question ?

[Vmax540]

I have a complete set of Roundslide 38's with throttle, oil and choke cables off a 540 and was wondering where to start out with jetting on the 81 SRX 440 ? The Main jets were 260's in the butterflys when I got it. Thanks for any help Chuck ! cccsc@csonline.net
