SO lets see if I can keep this up, I am running a parallel post over at http://www.oldskoolsuzuki.info/
So some of this will just be copied and pasted
You have been warned!
Here’s my deal, I have been planning a GS1000y build for a while now, first phase was to get the bike working and cleaned up with the idea of building it into a replica racer.
Here are a few pics of what it was and what I got once I was done.
Now it's time for phase 2, the engine build. This is my first build so please be patient with me; it’s going to be a big learning experience and project for me. To help guide me I have been working with Speedy Steve (he is a great guy plus he is only an hour and a half from me). We are looking at doing a stage 1.5 build that is easily expandable for future competition use. We are trying to use most of the stuff I have right now (yosh 1085 kit w/11.2:1 cr, oem exhaust valves, vm29 smoothbore carbs, yosh 4 into 1 2.5” dia header w/ canister or a yosh 4 into 1 3.5” dia header w/megaphone, accel coils, some basic things like that)
Basically this is my plan for the motor: ported head, 1085 kit, going to get the crank rebuilt by Falicon or Gardner Racing Concepts, keeps stock rods, having crank guy inspect them, I was thinking about going straight cut primary, gotta see what I am quoted first, a gs1100 billet basket (still researching this, I think I just need to cut it down a bit to clear the inside of the cover) I might get the gears undercut locally, got to see how much that is and what shape the tranny is in, going to run a msd mc-3 box based on Steve’s recommendations and last but not least paint the motor in kal guard gun kote to help with heat.
This is my basic plan and will grow change as I go.
Some immediate questions I have are in regards to my head, since Steve is almost done with it.
I need some new intake valves, I was thinking stock size SS, but am having a hard time sourcing some. Steve likes Ferrea valves but they don’t have any GS1000 valves. They would do custom but I need to get them the specs (anyone have exact specs so I don’t need to mail them a new oem intake valve). Kibble White and APE were options too but they don’t have any listed either, who have you guys used in the past? Any part numbers?
I have new oem exhaust valves I got a deal on so I am going to run them now to be cheap.
I am going to replace my guides with bronze ones, found some from Kibble White, what do you guys think? Anyone else you like?
For now to save a few more bucks going to run the biggest cam I can without going to under bucket shims, which I think is a web cam grind 110. I was going to get some web cam HD springs. Should I go to aftermarket retainer? Alum? TI? or keep oem for now?
I want to get my head built right so I am not spending extra money in the future I didn’t need to. Does anyone have any comments or suggestions? Any recommendations for the little bits like HD head nuts and such?
I am going to focus on the head for now, once that is almost all put together I will work on the other stuff on the list.
Another thing while the engine is out I was thinking about doing some bracing, do I need to follow the diagram for bracing you guys have posted? I guess what I am asking is what are the most important points of the frame to brace?
Thanks guys
