Yeah but not something I want to listen too every Spring morn when the air temp is 35 F. These busas run pretty cool even with stock exhaust. It can take a long time to warm up. Noticed mine was not even running at the half way mark on the colder days. Perhaps it is something I will live with for another season. Didn't seem to be a problem when the weather was warm.
I have received several comments on the ZX-14 forum I participate on. One person who has owned a great number of bikes through the years suggests that the automatic CCTs are best. He likens the manual adjusters to ignition points---it's old technology and requires adjustment.
On the other hand, I have not come across a single post where an owner of a ZX-14 has not been happy with their A.P.E. CCT. I have not found anyone claiming that the A.P.E. requires adjustment very often. Must say they set it and it has not required adjustment in the year or two they had the A.P.E. on the bike.
As for CCts in general, manual and automatic-----I have never heard of failure of either kind. There are warnings about what would happen if---but I don't recall anyone in the 3 years I have been reading these forums post about valves jumping time and colliding with pistons. I recall Brock writing that he had concerns of his ZX-14 cam chain breaking if he chopped throttle at top speed--but it never happened.
Thanks, Schism. I have printed off a copy and I will keep for later in the winter when it warms up enough to work on the bikes. :-)
