There has been tons of stuff written on this subject. The bottom line is this:
* About 4 out of 5 Cobra owners have problems with their HTOB.
* It is
incredibly sensitive to get set up properly.
* It provides absolutely no benefit over an external fork/slave setup.
* You should only use it if you absolutely positively have no room for a fork/slave. (ERA still does it on the FIA; Kirkham will not do it period, I believe.)
* When you replace your HTOB with an external fork/slave make sure you mount your slave to the frame so that it causes mysterious shifting problems from the engine/trans torquing over (that way we can all feel smart when we point how how dumb that was).
There, now you know everything there is to know about HTOBs.
