I put on the Kuryakyn Hypercharger on my 2005 V-Star 650 Custom. The pipes on the bike are factory which have been gutted. The bike runs great until I get into a good headwind. Then it acts like it is running out of gas. If I cover the butterflies with my hand as I'm riding, the bike roars back into life. I've been told that I need to go up one more size on the jets, but I'm not so sure. Any thoughts?
