Honda CB400 T still Revving High?

Question

new plugs, CDI box, carb slide springs, cleaned carbs, slides move freely and choke works, carbs are sychronized but after I twist the throttle it revs at 5000 rpm and will not drop again

Answer 1

-Check the air cleaner and air box cover intake. Dirty or restricted might act like it's on choke.
-Apply the choke when it's reving. Any changes? Carb problem.
-When you synced the carbs, did you perform an idle drop test?
-Adjust the pilot screws.
-When it's reving, put in 1st and slowly let out clutch. If rpm's drop, electrics OK.

Answer 2

I grew up in a very small town and High School was were all the activity was except for getting drunk and making out. I even did some of that at school. LOL It's hard to believe I survived High School and I was an "A" Student. School is were Girls were and were I played Football so I had a blast. It didn't hurt that by the time I started High school my Dad had quit drinking (He was one of the worst alcoholics I have ever seen) . Mom was still a pain but Dad and I became best friends, So I guess my view of my High school years is a little biased. The School Dances were big events in a small town that had one movie theater with just one screen, no fast food restaurants and no malls. We didn't get Rock Concerts coming within 150 miles so I didn't see my first Live Concert until I went away to college unless you count local bands playing at the Dances.
