i recently bought a gs1000 (early 80's?)motor on a blaster frame and am trying to get it to run right it currentally has shotty wireing, no air filters, basically open header exhaust, horrible carb tuning, and wont stay running w/o the choke on.

i so far have reset the carbs to a somewhat "stock" position this didnt help, the previous owner took them apart and cleaned them i'm not shure if he got them all back together right... it will stay idleing if i leave the choke out just a lil bit i'm not sure where the idle air screw is on these things i got a manual comming for mikuni carbs, i dont have a part number for them tho i looked everywhere on them w/o taking them off, they have 1-3/4" od air cleaner spouts on them, there are 4.. obviously all hooked together

i'm going to work on the wireing as soon as i get a new voltage regulator.

i'm searching for a cheap muffler to drop all 4 cyls. into one on the side, anyone reccomend a muffler to use? or mabye a size?

i'm going to tryan dget some air filters tuesday after the holiday weekend. from a local shop.

anyone got any ideas to help me out getting this thing in the dirt?

thanks,
-Erik

who makes aftermarket coils for the gs1000 motor?

Dyna or Accel coils will work. Check the ohm rating for your application (point, CDI, or electronic).

For Dyna:

For Accel:

Go to the GSResources for more info on that engine.

www.sudco.com should have what you need. They are the biggest Mikuni distributor in North America.
