ission confused with "sufficient contacts"... can anybody explain to me really quickly what DOES and DOES NOT constitute a substantial factor?
we had this one hypo in class where a guy from florida was visiting some girl in CA and assembled her new bike for her (nice guy). a few weeks later, she got tore up on her bike and she thought maybe the florida guy was liable, or maybe it was the corporation that mail-ordered her bike to her (principle place of business and incorporated in Utah).
Our prof said that venue was proper in the CA court for the nice guy and for the corporation, since thats where the accident happened... but this doesn't necessarily mean the nice guy has sufficient contacts there right? so if she wanted to sue both of them - WHERE could she actually go?

You're getting "minimum" and "sufficient" contacts confused. Minimum contacts are the standard for specific jurisdiction (International Shoe), and the general standard is the relationship between "the defendant, the forum, and the litigation" (Shaffer v. Heitner). Here, the defendant is likely being sued on grounds of negligence, a tortious action. This type of action is covered under every state's long-arm statute. Therefore, we turn to minimum contacts.
(This is a bit more informal than I might be on an assignment/exam, but it's close)
In this case, there are 2 good avenues to evaluating specific jurisdiction: the Calder/Worldwide Volkswagen "Effects" Test, and the Hanson v. Denckla/Burger King "purposeful availment" test. We'll use the effects test for the guy's tortious conduct. Under the effects test, we look at the effect generated on the forum state resident in that state. The defendant certainly aimed his behavior at the forum state by traveling to that state to see the plaintiff, and then assembling her bike for her. Furthermore, the plaintiff was then riding that bike in California, when a bicycle malfunction caused her injury. Therefore, the defendant should "reasonably expect to be haled into court" there (WW Volkswagen).
As for the bicycle manufacturer, under "purposeful availment" we would need to ascertain whether the bicycle was sold to the plaintiff within the state of California. If, in fact, it had, the company had purposefully availed itself of being subject to CA law by choosing to do business there, and would be subject to personal jurisdiction (Burger King). Otherwise, we must analyze competing views of minimum contacts. If we decide that "Stream of Commerce" is sufficient to establish personal jurisdiction, the bike company could have sold the bike through intermediaries to the plaintiff and still be subject to personal jurisdiction (Asahi Metal). Otherwise, we must again turn to see if the defendant would "reasonably expect to be haled into court" in CA. If it were foreseeable that the plaintiff would be riding its bicycle in CA, then the defendant would likely be subject to personal jurisdiction (WW Volkswagen).
On the whole, both the bike builder and manufacturer are more likely than not to be subject to personal jx in California.
Personal Jx is one area where it's a good idea to know a lot of actual law, because there are several different tests which are applicable at different times and can yield slightly different analysis. Obviously, don't go beyond the scope of your class, but the idea is to understand the important concepts, and I didn't even start to talk about other factors like "fair play and substantial justice."
Just remember to consider:
Actions directed at the forum state
Foreseeability of being sued in that state
Actions with effects in forum state that defendant should know would have those effects
Contracts with a particular state
Products sold in a state, directed or otherwise
That's generally a good start for considering avenues for specific personal jurisdiction. General jurisdiction is usually the easier case, reserved for sufficient (think extensive) contacts with a forum.
