Hi, I am a new member and owner of a Yamaha Radian. I am having problems getting the bike to start by using the start switch. I have checked the clutch switch and side stand switch and both seem to be working. I have put a new battery on the bike and can get it started by bridging the positive on the battery and the starter. Any ideas as to why it will not start? I also noticed that the previous owner removed the fuse for the power wires and just wound them together.

Any help would be greatly appreciated.

Thanks James

Hi James,

Welcome to the forum,

i was going to say check the kill switch is on but when you said the bit about the fuses being removed now i suspect that some thing has been frazzled. trace back where those wires go and then check to see if any thing else those wires go to work.

Thanks for the reply. Thats what I thought and am wondering if it is the CDI that has gone. I have got a friend coming up with his ammeter to check the circuit. Do you know where are the best places to check from?

Cheers

James

Yep, trace your wiring back, sounds like a break somewhere

Does it turn over on the start switch?

Does it maintain run when started?

Do you have the schematic?

Hi, does not turn over on the start switch. when I start it, it does run. all I have is a schematic from a Haynes manual.

Thanks

James

Just to let you know I put a new fuse on and the bike now starts.

Good result

Couple of "watch fors" on the Radian: Look after your front fender, prone to crack/break where the bridge plate sits and they are rare

As are the fuel tanks

Swingarm needs to be cleaned to stop carp buiding up and rotting them out, particularly behind the nylon chain guide that is screwd onto it close to the arm bearings

Good luck with it, fabulous little bikes
