Sucks for sure. Looks like you're giving the finger to the x-ray.

And sorry, can't help you with your electrical problem.

carpel tunnel release?
i had mine a year ago.. only took 1 week to heal.. unless you had your palm cut open ..it wont talk 10 weeks.
read "NOT A ZOMBIE YET" here on vfrd

lights.. your R/R is dying.. replace it :fing02:

My lights have always dimmed slightly while sitting at idle >>>slightly<<<. However, just before my R/R burned itself up, my lights and gauges went bananas for about 15 minutes but that was much more than what I would call "dimming".

On the injury issue, I've been off of my VFR for two weeks as of this past Sunday due to a serious bout with vertigo and a demanding wife that prescribed No Riding for one additional week after symptoms subsided. I'm off tomorrow and "home alone" so I'll be back on the bike for a lunch ride and can't wait. 10 weeks would be brutal. Best wishes!

You worry your bike rather than your hand?   I admire that!  :D

+1 -- R/R is dying or dead.....

the hand was table saw vs. hand.......i lost! going bananas sitting around. open the pool today and babysitting.6 weeks in cast 4 week physio.
wanna get the bike 100% ready waiting for me
upgraded shock from jamie....excited

have a new r/r will replace and eventually do VRossi technique to keep cool

Agreed, R/R. Had the same symptoms and upgraded to the R1 mod with new connectors all around. Make sure to check the output of your startor and all the connections in between (and replace if possible).

here's some great info about the R/R. I bought the connectors from the guy in Japan mentioned on this site.

That Triumph thread is the one that got me thinking about a redo of my charging system. I just reread it and its still a great thread.

- General notes -- the FH012AA R/R is replaced by FH020AA, its just the latest model.
- Eastern Beaver has some great stuff, but if your order is under 100 bucks, shipping is 20 bucks. (ouch) There are US suppliers for cheaper.

I don't think the R/R can be immediately pinpointed.  I would perform the full electrosport fault finding process becuase it could well be the stator which is weak rather than the R/R about to fry itself.

*Some* amount of brightening is normal; in fact many owners manuals state that the lights should increase in brightness a little off idle because 14.7 volts may not be possible until, say, 2,000rpm.  Under that it may only generate 13 volts or so, which is still enough to charge the battery.  However as with any bulb if you increase the volts you increase the brightness so the jump from 13 volts to 14.7 volts can be seen.

Essentially you should hook up a multimeter and watch the voltages.  If the voltage is over 13.2 volts when the lights are dim, and peak at about 14.5-14.7 volts when they're bright there is nothing wrong with your bike.

^^^ +1  - I'm with you on grabing a multimeter and checking voltages, may as well check it with data..

- my old 4th gen did the "dim" light at idle and "super bright" thing at revs when the R/R crapped out.
