I recommend buying the factory Suzuki service manual before doing any in-depth maintence/modification items. Don't bother with Clymer/Haynes manuals, get the year/model specific manual from Suzuki.
Getting the carbs on and off is the major item, jetting is easy if you follow instructions carefully. Go slow and do one carb at a time so you will have a backup if you forget the order of assembly. The needle clip parts are small and must be in the proper order, so pay close attention.
Get your hands dirty, don't be intiminated- it is not rocket science, the most important thing is attention to detail. I started on my '83 750ED when my bike came back from the dealer after the 600 mile service missing fasteners. No one is going to take the time and effort that you will when working on your own bike. The effort required to learn will be worth the end result.
Ivan's jet kit has pretty good instructions for assembly and a diagram for drilling out the airbox. New needles and mains are supplied with the kit. You have to drill out the cover over the mixture screws. Just go slow-use a cordless drill with the supplied bit. The cover is very soft and will come out easy- do not allow the drill bit to penetrate thru into the actual mixture screws.
I have been running a tad rich lately (confirmed by plug check) with the 90+F temps here in Dallas. Bike has had an off idle stumble along with excessive popping upon throttle closure, so today I adjusted.
Current setting:
Mixture screws are at 3.5 turns out
Needle at #2 position (from top) with the supplied shim used (app 2.5 position from top with shim)
Mains are still 115
Test ride app 40 miles today at 90F ambient temp. - the bike flat out hauled a$$ pulling cleanly from 4000 rpm to redline. Absolutely no defects.
Hopefully this helps, Ride On Ed.
