Minimum electronics to run the engine.

[T0A0C]

Hi Guys,

Im in the process of fitting a 250 engine into a chinese bike which had blown the final drive. What are the minimum components I need to get running.

I have the following so far:

Engine from a 2011 bike
Wiring loom
CDI
Junction box/relay box? (Part with 3 plugs)
Fuse box (part of loom)
Throttle bodies with 3 sensors/plugs & injectors
Lambda remove plug
Fuel pump/tank
Upright sensor
Starter
Regulator


Im hoping I can use the starter solenoid and coilpacks off the original engine but will have to check fit.

Will this be enough to get it running?

Any help much appreciated.

Thanks

Tom

I have been here. While it is a different application, I have put a Yamaha Banshee motor in my Ninja and needed to figure out the wiring. I would recommend that you get a good copy of the factory diagram and start studying it. There is a TON of stuff that is cross connected. Relays, switches, individual components, etc. Removing one part affects the operation of another. It's more than just small things like the sidestand switch too. If you are real sharp with motorcycle wiring you should be able to figure it out, but if you look at the diagram and your head spins, you may wind up chasing electrical gremlins forever.

Thanks for the reply. I think I've got it now. I finally managed to track down the UK wiring diagram with fuel injection and it makes pretty good sense. I was going to splice the standard speedo but have decided to get a set of ninja dials to make it a lot easier.
