Electrical problems with CBR F2

Subject: Electrical problems with CBR F2 Tue Feb 24, 2009 7:50 am

If you own a CBR F2 (1991-1994), then you are GOING to need to replace the regulator/rectifier, and also the battery when you do so. This is because the rectifier goes out, causing either an overcharge or undercharge from the stator (like an alternator on a bike) to the battery. This over/under charge damages the battery over time, which, if you do not replace before buying and installing a new rectifier, will in turn damage the new rectifier. So, buy a good rectifier (one that costs over $100-don't buy the cheap one) and a battery, or you will be stranded without power in the middle of nowhere!

Hi,

I've actually sold my 600 f2, so I vaguely remember what the set up looked like and I can't really take pictures for you, sorry. Is it possible for you take some pictures? it could help us out a lot to see what's missing on your bike or what could be causing the problem. I'm pretty sure the right side tail section of the cbr 600 f2 should have the ecu, the rectifier/regulator and the the plug for the wires coming form the rectifier which can melt and cause poor connections sometimes. there are also many other sites that may be able to help you out too. here are some links.

what parts fit the f2 from a 94 honda cbr fireblade 900 ?

Not sure, the rear wheel off the fireblade looks the same and the rear brake rotor looks the same, but they could use different spacers and such. I know the gas caps are the same for sure. the mirrors look the same too. there isn't too much else that would bolt right on without further modifications. what exactly are you trying to do?
