Honda CB400 Questions & Answers

Does the CB400 revo have an ECU communication wire that runs to the clocks (instruments) if so, does anyone know the colour of this wire in the back of the clocks ? I ask, as I have a CB1100 RS, that I fitted CB400 vtec Revo clocks to. My wire is white, from ECU on wiring diagram it is the M-TXD/RxD communication wire, and now I need to connect it to the Revo wire (if there is one) Ideally, I need a wiring diagram for the clocks, or whole bike can you help ? If so. Please send to: [Content Removed] Many thanks, Dean

I have cb400 revo. My problem is rpm 5500 cut. Any ideas?

Hi. I am owning a cb400sf spec 1. Unfortunately the original CDI unit got blown. I couldn’t find a spec 1 CDI unit. So, I replaced with a non vtec CDI unit until I find a spec 1 cdi unit. Does it harm for the valves or piston or any other parts inside engine for using the non vtec cdi unit. Because when I rev more than 6500 rpm, still two valves only gonna work for each cylinder. So those two valves only bear the pressure inside the cylinder when it runs in a high rpm. Please someone advise me on this matter. Thanks in advance
