Im looking for yamaha srx 400 maitenance manual and parts diagram

SOURCE: Yamaha SRX 400

I'll post the address for you to get the manual you need and the web site has an online parts manual but it does not offer a repair manual for free. Do you still want the web URL?

I do not believe that is available. Ihaven't come accross one yet. Hayes, or Clymer may be a good manual to help out.

SOURCE: Is a 1990 Yamaha SRX 400 rare? and How much would it be worth?

I'm not sure of the value but there is a SRX web site that should be able to give you some idea and offer guidance to finding parts or fixing problems with this bike Check them out and let us know how it works out.
