600 RR Riders,

New member and First time posting. I hope someone out there could help me with this issue before I tow my bike to the dealer. I was surprise to see how many CBR 600 RR owners are also tackling this “WON'T START" issues after having no symptoms of this issue. It works fine and after a few minutes or hours, the bike will not start? It sucks. Luckily I encountered this prob in my garage.

I own a 2012 CBR 600RR and recently came about into this problem after just performing basic maintenance, Oil Change and Air filter change. What puzzled me is, the bike started as soon as I was done with the tune up. No problems, check for leaks and shut it off. The next morning, I could not get it to start anymore.

Turn on key, I have plenty of gas in the tank, could hear the Fuel pump priming, the Relay’s clicking, Kills switch ON, Bike in Neutral, but will not turn over.

Started reading and researching this “WONT START” complains in the web and there were plenty. Using my lap top, Volt meter, 12 volt battery and Bike Manual, I decided to trouble shoot the issue. Removed all the plastics / covers and performed the items below: Plan to do the highlighted items this weekend.

1) Checked the Battery and it was time to replace. Bought Brand New Battery from Dealer same model, got it tested (Pass) –– Still Did not turn over / start.

2) Checked all the fuses, the 4 relays, (energized each one for “clicking and continuity), checked the 30A fuse, integrated to the Starter relay harness, also energized the starter relay and check for continuity, Tested OK

3) Check the Diode, using volt meter and manual procedure – Tested OK

4) Checked the Bank angle sensor using manual procedure – Tested OK

5) Checked the stand switch using manual procedure– Tested OK

6) Checked the Neutral switch using Volt meter and manual procedure– Tested OK

7) Removed each spark plug and checked for “Spark” – Plenty of spark to each plug tested Ok

8) Checked the PGM-FI Unit connectors for bent pins and made sure connectors are securely lock in place.

9) Checked and made sure kill switch is “ON” DURING each attempt to start- Does not want to kick over.

10) Checked compression to each spark plug. Work on it this week end.

Replaced spark plugs with Factory IMR9E-9HES. Work on it this week end.

 

The starter relay tested good with continuity, but is there power going through it and getting all the way to the starter?

Please clarify that this is a no crank issue and not a cranks but won't start issue.

 

I will check that this weekend. I'll keep you posted. thank You so much.

 

The bike cranks it just won't "turn over".

 

Well, that's totally different. The power is obviously getting to the starter.

 

"Turn over" is the term generally used to mean the starter is cranking the engine over, thus proving that the battery, starter relay, and starter are functional and the engine isn't mechanically locked up. On a bike that normally runs fine, this is what you'd see if the kill switch were flipped from 'run' to 'off'.

 

or if the kickstand switch was failing. or the bank angle sensor.

Yeah, "turn over" to me is when the engine turns/cranks. When the engine won't start, I say it won't fire up, or it will crank/turn over but not start.

OP, did you ever get it started?
