Comes with what's called a regulator rectifier, or on older bikes a regulator and rectifier. Sounds like this one's is toast. A common issue and easy fix. Or could be the stator.

I didn't read past the few first post so my apologies if this was already said. I've worked in the M/C industry as wrench/service advisor and sales for the past 6 years if you have any other questions, shoot.

Yup, they used to be separate on older bikes, all one unit on newer ones (post early 80's).

so thats it then? all or nothing? you are either dead or a little rashed? full race gear or helmet and t-shirt? so simple!

I guess I can throw all of my gear away now and get a sweet icon helmet and ride around with impunity now.

For the record with a good mesh jacket, I sweat about exactly the same as if I was naked, and having gone down with one at 100mph, they are good enough to walk away from it with just some scrapes and bruises. The jacket was toast, but it did its job. Mesh is awesome for hot places

And full leather... I feel like I'm in a bubble. you just hop right back up like nothing happened and go grab your bike. After 3 track downs, the leather doesn't even look like it's been used. awesome, but impractical.

I've already mentioned the huge scar on my side from a 35mph wreck with no gear, considering I don't sweat any more with a mesh jacket, it's a pretty obvious choice.

2.) Just 'some jacket' isn't enough. I don't know what dude gave you with the bike, but I won't ride to the end of the street with an Icon/ Joe Rocket/ etc squid jacket. I'll ride Alpinestars, Dianese, Vanson, etc. If it wasn't made from big, mean German or American cows, and filled up with well designed multi layer armor, its not safe enough. Rash is a miserable thing.

Thurday afternoon, one of my buddies fell off his R1 in only a helmet, and looks like a walking scab. Palm peeled open, asphalt burns everywhere, and a dislocated elbow. He was just minding his own business on the way to lunch and a puddle of oil jumped out from under the Burick in front of him. You do not want this. Wear a jacket, gloves, leather boots, and a lid made in the US, Japan or Europe. Every time you hit the starter button. No other choices.
Exactly why I was happy to pick up this F2. Heard they are reliable and will last. I don't need anything super fast or super new/cool, and this bike just does the trick. It's been down before so I don't have to get all pissed when I lay it down myself.

I figured out some stuff on my gear, and after looking it up, it looks decent, not top of the line by any means though. I've got a Vega mesh jacket, an HJC helmet, and some Alpinestars carbon fiber gloves. The gear is good for the weather and good for just cruising around here. I can't see myself getting all dressed up in full leathers and boots.

And to all of you tools that full leather up to drive around town. lol Its not a bullet prood vest or magical armor. If you get t-boned at 50mph your probably going to die no matter what your wearing. I agree that road rash sucks but so does showing up to work with swamp ***. I should start wearing my roadrace suit, gloves, shoes, balaclava to the grocery store for laughs. Does anyone wear a metal chain suit like for shark diving? Post pics if so. I bet it would breathe better than 2mm thick leather.
^ I'm with this guy. I'll be bringing the bike in to have it checked out and probably have them change the fluids, check the forks/brakes, and then have them check out a unhooked hose underneath that I noticed yesterday. Maybe I can get a picture of it on here if anyone wants to see what I'm talking about. Other than that, the bike has been great.

Thanks for the input everyone, it's appreciated. Glad to know I've got people on here that know their stuff because after just browsing for an F2 forum, I can't come up with much. Curly, you've had very helpful info, thank you. I'll be looking into the R/R and stator issues.

Does it have carbs? That unhooked hose is the overflow. Come to think of it my buddy's 650r has one and it's fuel injected. It's supposed to stick out an inch or two past the frame, right about where the foot pegs are.

here ya go, scroll down to the picture with the fairings off.

you can see two hoses unhooked by the kickstand pivot.

Yep it's got carbs. It looks just like those hoses in that last picture, but there is only one. It has a tiny little hose clamp on the end of it, which is what made me think it should be attached to something though. I'll see if I can go out and snap a pic.

Can you trace it back to it's origin? Does anything come out of it, lol?

Doesn't seem like anything comes out of it, and it seems to run to the gas tank.

To the petcock, or to a separate breather fitting? Does it have a fuel valve/ physical switch?

Most likely it went to the airbox, to reburn any fuel vapors.

Or to a vacuum operated petcock. I can't remember if F2s/ F3s have a mechanical one or not.

I believe he said it was running, wouldnt do so without the vacuum line hooked up, unless it was in prime, in which case he would be asking about his recurrent fuel puddle.

Not necessarily. I owned 4 carbureted bikes before I came across one that would bleed fuel if the petcock was left on. If the needle valves are tight enough, it would be fine.


I do think you're right about the tank vent to the airbox, I'm just saying it's a possibility.

Just a tidbit for you to consider, having owned a bunch of bikes notorious for having bad R/R's

replace it with one from a new cbr600rr. get on ebay and look up an FH008 regulator and do the requisite reading (being a member here, that should go without saying) on fitting it. They run cooler and charge the battery better.

Word is getting around that this is a hot setup. Both Aprilia and Triumph communities are 100% sold on this, and it's like $40 so if you got to do it anyway...

I'll definitely look into that tasty danish.

Here are the pics of the said hose.

Yeah that should go to some sort of vent, it's plugged back into the air box for emissions. Leave it as is, although if you really want to hook it up, it'll go to a vent somewhere on the carbs or gas tank. Carbs should have two, one between 1&2, one between 3&4, my particular gas tank has two, one in the front, one in the back, both along the spine of the tank, on the bottom.
