I had a very neat list of required and optional parts typed out then my computer froze so here is the condensed version I will avoid mentioning piston rings as if you end up getting weisco to machine new pistons for you they will come with rings;
Required;
1-550 8-valve Engine
1-650 8-valve Engine
1-Gang of 4 Mikuni BS32SS CV carbs
1-550 Gasket set (search ebay for GS550 gasket set)
1-650 head gasket (I bought both 550 and 650 sets but the head gasket can be purchased separately)
1-650 Base Gasket
2- crank end seals you can get them as NOS from bikebandit.com as you will likely destroy them when you split the case.
1-Oil Filter
X-Quarts of oil (Be sure to calculate the volume of an oil cooler if you fit one, and they do help to dissipate the increased heat of high compression pistons)
Note: It is necessary to bore the crankcase out slightly so the larger cylinders will fit, I suggest having this done by a shop (which is NOT what I did) as it makes fitting the cylinders much less of a headache.
Optional (but recommended)
1-New Cam chain (it may be possible to reuse the old one)
1-Manual cam chain tensioner
1-Digital Igniton such as the dyna s or better yet a dynatek 2000 or 2000se
4-New sparkplugs
1-Set of new wires
2-Dyna coils
I won't go off about transmission mod's as they are costly, however for my project the transmission was an absolutely crucial element in achieving the desired characteristics, the required machining must be done before you reassemble the case halves(obviously). Let me know if you want more information on this.
and of course there is always, conversion to fuel injection using microsquirt or one of the many other EFI microcontollers out there. you could do forced induction with an AMR300 compressor ect...
lookup Dansofield550 he has the finest example of a GS674RR that I have EVER seen(photos of) excellent work.
