Yea, it's really easy to adjust the throttle bodies. Do it in this order: 1. Take tank off. 2. adjust screw half turn.+1 for throttle bodies. If you want to DIY its a bit of a FAFF but not impossible. You'll prob find one of the screws is completely closed. Opening it half a turn will probably stop the stalling even if it doesn't perfectly sync the throttles. There was a post on here recently about someone who did it without taking the tank off.
