don't be so sensitive. most of the issues here ARE self inflicted. are you not reading the forum? most of the advice on here is bad or misguided as well. if you read the posts here and disagree with this then you're not paying attention.


and yes, i tell people in a blunt tone in real life. if you ask a question you'll get an answer. it's how i am. and no i don't get offended if someone calls me stupid. especially if i'm being stupid. who cares?

Bought the R/R from Rick's Motorsports. So far so good.
Obviously I can't full on road test it as there's snow here now. But my resting voltage is high 12's. My charging voltage is 14.35.

2003 CBR600rr Starting Issue

Symptoms: Initially the bike started fine. Turning it off at or above 200 F and trying to restart would not work. The bike would have a few weak cranks before completely shutting down (clock and miles reset). This problem eventually got worse, as the motorcycle wouldn’t start even when cold.

Trying to diagnose the issue: Some of the forum posts were helpful. The suggestions that I found were 1) replacing the battery 2) replacing the regulator/rectifier 3) inspecting and cleaning the starter 4) cleaning the grounds.

What I did: Not wanting to spend too much on a good regulator/rectifier without knowing what the problem was right away, I decided to attend to the easy options first.
  • Voltage tests on the battery indicated that it was no longer holding a full charge. I purchased at ~ $40 battery from amazon (Mighty Max YTZ10S 12 V 8.6 amp hr) but decided to take a look at the starter and clean the grounds before potentially subjecting a new battery to undue strain.
  • The starter was a bit more difficult to get to than the CLYMER manual had led me to believe. After taking the left side fairings off, disconnecting the fuel tank and coolant hoses it was finally accessible. A bit of force was needed to slide the starter out (I’m pretty sure that this has been the first time the starter has been touched since the motorcycle was built).
  • I took the starter apart and cleaned it out with some careful WD-40 application and then applied dielectric grease to the electrical connections. As you can see, there was some carbon build up from years of use. The starter passed all of the electrical tests suggested by the service manual.
  • While the motorcycle was opened up, I decided to clean all accessible coolant hose connections and replace the gaskets (this also probably hadn’t been done in quite some time – the gaskets had been pressed flat).
  • I put everything back together, cleaned the open electrical connections/grounding points, put in the new battery and replaced the coolant with some nice genuine Pro Honda HP Coolant (why not at this point).
  • Finally, I tested the regulator/rectifier as shown in the service manual. It passed the electrical tests.
This seems to have fixed my problem (even when driving in traffic on a hot day for 40 ish minutes and then turning the bike off/on). The motorcycle has been fine for over two months, and I’ve put on about 1,000 miles since then.

Hi everyone,

I bought 3 weeks a go a cbr 600RR and have the same issue.

RR wont work when it is hot. When I press the start button when its hot, the system is recovering itself.

By a cold start it works fine. And after 20 minutes of rest it works also fine.

First I will check the voltage of the battery before and after the start and follows the steps of Jules03.

I am new with bikes. I have for 1 month my driving license now. Hope i can fix it.

Greetings from the Netherlands!
