I rebuilt the VM26SS carbs on my bike and forgot to count how many turns out the pilot screws were before I took them apart. Any one know a good starting point to set them at for initial fireup.

Fuel or air?
Fuel - 3/4 to 7/8
Air - 1 1/2

Pretty sure it's fuel. The screws are on the engine side of the carb, underneath, just ahead of the float bowls.Comment

Pilot screws are the bottom ones and mine are at 1 out..the air screws are on the throat sides and mine are at 1 3/8 out..Plugs are running just slightly tan like you want. Thats my bike of course,, but this will be pretty close for your as well.MY BIKES..1977 GS 750 B, 1978 GS 1000 C (X2)

I would rather trust my bike to a "QUACK" that KNOWS how to fix it rather than a book worm that THINKS HE KNOWS how to fix it.Comment

while your statement is correct for the most part chuck vernon BC is at a different ALT than you are and also not as hot so he has more air densityOriginally posted by chuck hahn View Post
the settings you have are a good starting point but he will wind up differently after doing some plug chops and tuning the carbs properly for where he is
i say this because in vernon the ATL is about 1200 ft ASL here in calgary i'm at 4300 ft ASL and with my bike tuned for here in vernon i run a tiny bit lean but not too much at Sea level i will be on the borderline of being too lean for extended riding i would need to richen up my bike to keep it safe if i spent a long period of time there
so as can seen this is why each bike is different when it comes to tuning it and ALT and temp also play a roleLast edited by Guest; 04-09-2011, 06:27 PM.Comment

Thats all they are intended for..I am sure he knows he is gonna have to fine tune everyting. Every bike is its own animal. If my neighbor had the same bike, his would be different than mine too...Last edited by chuck hahn; 04-09-2011, 06:23 PM.MY BIKES..1977 GS 750 B, 1978 GS 1000 C (X2)

I got it..just added a bit.. Its funny that so many factors can effect the adjustments...even on the same bikes in the same environment.MY BIKES..1977 GS 750 B, 1978 GS 1000 C (X2)
