Me too looking to fit a Goldstar type silencer. Is there any difference in quality, between the WS one and the Hichcock, or are they the same animal.
If you're looking for vacuum leaks an unlit propane torch can be handy. Move it slowly with the vavle open. If the idle goes up it's sucking in propane where you've got the torch. Of course do this outside Scott
I mentioned 'unlit torch' but it never hurts to say it twice. Scott
Your bike should not stall so frequently that it puts you in some uncomfortable or dangerous situation on the road. I do not know how many miles you have on your C5 (guess that is what you have). These bike do get better generally speaking. However, you may try the following as well -When you start your bike, do not run immediately. Instead wait for 30-50 seconds after starting your bike and then go. A better plug might help. Also check your idle setting. Here is a video on how to set idle on UCE RE G5. I guess C5 also has same set up. http://www.youtube.com/watch?v=w51XKoubABI
Ok, I watched the video. The C5 adjuster is buried under the gas tank. Which way do you turn the screw? Clockwise for higher rpm?
