Very impressive Tweakin, a super clean great looking project! I'm getting ready to go back into The Beast this fall and bikes like yours offer lots of inspiration.
Where did you get the tail light from? I might have missed this earlier in the thread and if I did, sorry for asking the same questions again. I have one that I added from a R1 but it is pretty big and I have had some issues with license plate clearance. Although if all I have to do after the first few rides is straighten a license plate I think that's pretty good!
I also did the same thing with the wiring. I rewired the entire bike but didn't replace the regulator or rectifier and same deal, those old bits held together for about a month after I got her on the road.
I didn't find this forum until I was hip deep in the first incarnation of The Beast, wish I had because I could have saved some headaches and had a better plan. I have been spending much more time looking around here and getting prepped for the 2nd coming of The Beast next summer. Threads like yours here offer a wealth of information, inspiration, and ideas, big thanks and again the F2 looks great!
