Outstanding. The WestCo is ideal for a big V-twin. I barely have to stroke the start button and my twenty year old Wide Glide bursts into life. Definitely the best yet. Fits the battery tray perfectly. Just make sure you get the version with the positive terminal on the correct side, as they do two versions and the bike's cables aren't long enough to accommodate the wrong one. Highly recommended.
