Bumping an old thread as I just went thru some of this.
Running HID lows on my Gen1 for last couple years and I love em.
Ive gone as far as adding an external switch and relay to have the HID off at start up. The ballast, bike and battery was happier this way.
Its nice having the HID off at startup, even more so now that im running a big bore 1397 and my starter is wired for 24v with another battery in my hump.
Back on the topic... Wont go HID highs as I want instant on.
I tried PIAA xtreme halogen highs, that was a tiny bit better than stock halogen. Based on others reviews, I was expecting alot more!
Installed LED highs tonight and I am a happy camper. Massive improvement over stock or PIAA. I recommed this for anyone still stock, its worth the $ and easy install.
Always need more light. Going to external fork mounted lights next...
