I recently bought a 1985 Honda XR250. It's a great running bike but is hard to start first time out. Can using the engine decompressor help me in this matter? I have never owned a bike with this feature and I am unfamiliar with it's function.

What are some other suggestions to help with a cold start on this bike. My wife has a 2000 XR100 that starts everytime with 1 or 2 kicks and no decompressor lever. This annoys me because she can start hers and take off while I'm still kicking on mine.
