91' CBR F2 Problems
 

Hey guys I'm new to the forums. My name is Mike and I'm pleased to meet everyone and I will thank everyone ahead of time because I'm positive the community will help me a lot along the course of me owning this bike. I've been riding since I was 6 and now I'm 18 so I'm pretty experienced.

Now to the good stuff. I bought a 1991 F2 for 800 bucks. The plastics are in good shape with cracks here and there. It has 2014 tags and a new plate not put on the bike yet. It has 52,000 miles but only 10,000 on the rebuilt engine. However the bike has a charging problem. I did my research and got some useful info but I want more input. The battery seems good I charged it and can literally turn the motor over for minutes if I wanted to. The bike runs really well until the battery dies. Also when the bike runs I noticed the rectifier makes a ticking noise and gets hot within minutes of running the bike. So I pulled the plug and it was completely toasted. Where do I start from here repair wise? All help is greatly appreciated.

How do I post pictures? I don't want to take the time to link them.

Photobucket is the easiest way. Just copy the "IMG code" to your post.

Faulty R/R is a common issue, though my bike has 25,000 miles and it's still good, I've got a spare on hand for when it finally croaks.

Just get you a new one - allegedly, the new Honda part number, which replaces the old ones, is for a much-improved part, that dissipates heat better, but most folks just buy an aftermarket unit with lots of cooling fins. There are quite a few options out there and some guys install an R/R from certain vintages of GSX-R 1000's or 750's, and soder in the proper connector.

Ah, now I see your pictures! Nice lookin' F2, by the way! :icon_clapclap:

Anyway, with that connector being fried, I would still suspect your R/R is bad, but that doesn't look the same as the original unit - I'm not sure if that is the newer Honda replacement, or aftermarket, or what, but either way, it's probably shot... that sucks. :icon_frown:

So can I rule out a bad stator? There is a junkyard and I can pull a r/r for cheap

Well, the only way to determine whether or not your stator is bad, would be to perform electrical diagnostics, but no, a bad stator won't do that... fried connector means overheated R/R.

Good luck with it! :icon_toast:

Thank you so much. I was hoping the stator was good. But it was a pretty good buy for 800?

Horrible decision bro.
I'll tell you what though, i'll take it off of your hands for the same price.
