What's the baffle on it? Street or one of the competition series? A street baffle would be OK with stock carbs and it will pick up a bit, but if you have a competition baffle on it a rejet will really make it wake up. I have an old megaphone system with a medium competition baffle and a stage 3 Dynojet kit on the 750 and it works real well 8) Some people experience a lean carb situation with a too free flowing system and it's hard on the motor, thats probably why Dom asked.

Do they have jet kits for VM carbs. That is what's on the '77-'79. I just put a 112 in mine when I put pods and pipe on and adjusted the needles and mixture screws. Did not touch the ones underneath though.

With the VM's you should be able to get the jetting right without a kit. The needles are already adjustable. Bigger mains might be all you would have to replace.

Damnit, I knew I should have bought an older bike.

how would you know if their vm carbs or not?

All GS bikes prior to 80 had VM carbs, the CV carbs have a round top, the VMs don't. That's the easiest way to tell from the outside.
