Re-jet for 1100?

[Tom MLC]

My '78 GS1000 has had a winter upgrade. 1085 kit, and GS1100GK cams. She was already jetted for pipes and pods. 138 mains & I think they say 75 on the pilots (I need new glasses).

Any way, the question is, should I install the 142 mains? Now's the time...I got the carbs on the bench.

Quickly now Carb Guru's. I gotta ride today!

This is the Red bike?
34CV's? If so, the 138's should be too fat and the pilots might be 45's?
I would try closer to 125's on the mains. JMHO.

VM-26's.

Definately not 45 on the pilots. Either 15 or 75.

I can't go down on the mains, unless I still have my stockers. The Dyno jet kit comes with 138's & 142's.

By the way, the bike ran fine before the mods, and probably will do so now. This is just a matter of timing. If I'm gonna change jets I might as well do it now while the carbs are off.

Carbs are dumb - they may not even realize you've made changes. Why don't you just put them on and see?
