Hey Everyone, I have a couple quick questions. I have what is registered as a'79 xs special. I purchased it a couple years ago and tore it apart. I have recently got it back together with the parts that were originally there. It has the reg/rec combo but will not pass the slap test. When...

So I took my xs out for its maiden voyage since hardtailing it. Seems to have a significant pogo effect in the front end when simply driving straight at speed. I am using the original stock front end. It was a 79 xs650. Any advice appreciated. Cheers

Ok, I need to purchase a new battery and know nothing about them. I am just looking for the cheapest replacement for the stock battery. It will be on my bobber which is pretty stripped down but at this point I still want to be able to use the starter. Other than the started I simply have the...
