The flow has now dropped to 100cfm as air flow does not like bends. The shorter straighter velocity stack kit only chops off about 5cfm in total giving more flow and power. The kit also shortens the tuned length of the intake system improving top end. Avoid fitting just a pod filter on the back of the throttle body . You will get a large loss. The intake /velocity stacks are important and serve more than one purpose . I think benno made his own - give us pictures

Thanks Chris. I've read about these kits installed on the fuel injected bikes, but have yet to see a carbed 2V with a velocity stack kit. I was wondering about the clearance under the airbox, etc. I'll see if I can't do a little more research on this as I would like to get the most out of my engine.
