Purchasing a problem

[agrant3]

Hey yall, I am in the process of purchasing a XS400. Unfortunately, the PO has informed me that the bike will not go above 30-40 mph. I was hoping someone would be able to tell me what might be wrong so I know what I'm getting myself into. I know that there's no way someone can give me a 100% accurate diagnosis without actually working on the bike, but I would appreciate hearing anyone's ideas.

Well, if it starts and runs you have a beginning. It could be any number of things, without knowing some more specifics it is hard to give an accurate diagnosis. It could be something as simple as a carburetor cleaning and jetting or even just timing or valve adjustment. More information might help the more experienced among the group to dial it in for you. Good luck and welcome.

Roll the dice! Lol.

I bought mine with a seized engine...

The major concern is that it has decent compression in both cylinders and they produce similar readings. From there, you can basically rule out major engine work.

Feel carb related....if the price is right...get it, go through the carbs and go from there
