Being cheap, i did almost the exact same mod. I put the turn signals in the last set of holes though. Also, instead of buying the signals, i got a set of old harley signals from my friend. I took the dual element out of the stock signal and used epoxy to fasten it in the metal housing.  Also changed the risers, handlebars and added the "engine guard" this winter...
Here is a before

and after

sorry for the messy basement  

Hi Frost,
those turn signals are identical to the ones I had on my previous Yamaha XS 250 cruiser!!!
That machines was great, 130 k/hr with a 2-cylinder 250cc engine on a freeway WOW, it was a loud RRRRAAAARRR
I sold it to get my Savage, I don't miss the Yamaha, but I know it's still riding around town...

Take care,

RW
