Welcome officially to the group - ride safe. A few things to consider:
1. www.bikemaster.com - this is THE place for your replacement turn signals. They are about $25.00 a piece, and you can get them at any local dealer that sells Bikemaster products. Do not be discouraged by the price. These T/S are an exact match cosmetically to the stock ones, but they are made from much more durable materials that will last a lot longer, and withstand the incidental rub that everyone does once in a while.
2. Tires that are 4 years old, regardless of the non-appearance of dry rot, or the amount of tread left, need to be replaced. Here's why - the rubber gets hard as the tire is drying. When that happens, the tire's ability to grip the pavement drops significantly. I have preached this incessively now, and I am utterly ashamed to admit it, but this very issue contributed greatly to my crash last month. I was on a new bike with much differerent brakes. But it also had an old tire (only 3 1/2 year old, but noticeably hard) with about 1500 miles left of tread. I planned to ride if for a month and mount a new tire before a long anticipated riding weekend. STUPID mistake. In a panic stop, I grabbed too much rear brake, the rear tire locked up WAY too early, and down I went. After changing my rear tire, the grip was like a whole new bike. PLEASE DO NOT MAKE THE SAME MISTAKE I DID. I will never do that again.
Let me back up that very correct statement! The one thing that I did not check before I bought mine was a proper check of the tires. After a week or two I noticed a few tiny dry rot cracks here and there, but the tread was still like new. I asked the dealer about it and he said not to worry, plenty of tread.
On a hunch I looked at the sidwalls and discovered the tires were 5 years old. I decided to be safe and replace the tires anyway. It took a few days for the new tires to get here. The day before I went in to the shop to have them replaced, I almost ran into a couple that was walking accross the street because my back tire locked and skidded, when it shouldnt of.
