I'm new to the forum, and I just got a 1500 drifter after riding a yammi roadstar for the last 7 years.
Anyway, the first thing I noticed is the Drifter uses the same turn signal flasher as the Roadie, and, I found a mod for the stock flasher that allows you to convert to LED lights and keep the DOT flash rate, WITHOUT resistors. I'll dig it out and post it if anyone is interested and can point me to the part of the forum to put it.
That sounds like a cool mod. It would go in the "Mods" section under the electrical heading. http://www.vulcandrifterriders.com/forum/index.php?board=129.0
My bike has a after market harley "safety lighting" kit that allows led turn signals at stock speeds and allows for 3× blinking tail light which i find to be heavenly in use with L.A traffic i pull front or push on foot rear brake and the tail lights flash 3 times very bright and rapid then stay om steady. Driving to work at 5am in the dark i have seen vehicles around me slow much more with the flashing light bc it grabs soo much more attention
