New shocks?

Yea, my bike rides like an old bike. Shocks must be 30 years old. Feels every jolt in the road.

What are the recommendations for getting new back shocks, or to not? Does it tune up the back end nicely? Is it worth the time and effort?

How much should I expect to spend?

Make a BIG difference . Search Ebay for Koni's or Works models . They are quite pricey , usually more than $200 for a nice used pair . Worth every cent though . Most twin shock KZ's are interchangeable .
