Hey guys. I've been considering removing the choke plate on my 670 Street Avenger (vacuum secondaries) to maybe get a little more flow (I never use the choke). Then it got me thinking, why not mill the entire choke horn down? I read somewhere that this can be good for 30cfm of airflow. My engine is right on the edge of where I'd need to step up the carb size from my research, so instead of ponying up the dough for the next size up, I thought maybe this would be a good way to go. I've also found my engine prefers a vacuum secondary carb over a double pumper. My question is: Is this a good idea, and is it even worth it on a vacuum secondary carb? I've done some research on the 'net and have seen no real drawbacks to doing this, but I haven't seen anyone do it on a vacuum secondary carb. Thoughts?
