A zxr400 is not.

Suspecting water to be the problem.
It dropped to 3 cylinders this morning in the pissing rain on the motorway halfway to work.

IF its not pissing down this weekend I shall be taking the tank off, pulling the plugs, draining the carbs, and making sure the plug well drains are not blocked.

Any other ideas?

gotta go with electrical, especially if its rain related...

check HT leads, coils etc...
