Ok,
    i've decided a louder can is in order, but i'm far too tight to replace the standard one given it's in good shape & i've a long list of other "to do's"
 
I'm guessing there's some wadding put in there by Mr Yamaha & co.
My question being~ is it possible to remove some of it for a more sporting exhaust note & if so how?

One of the funniest ebay listings i've ever seen.
Well worth a look,for laughs.
 
Imagine it~ a police bike fzs600, envolved in a high speed 10mph chase!
Reckon it must have been a 'B' movie or they'd have used a fazer thou

 
 
Factory manual specs 14.1-14.9v no load voltage for regulator, & 12.8v for battery (no load).& a 0.2-2.5v rise from this when charging.
 
Your Supposed to check charging circuit @ 5000rpm. This can be quite disconcerting for anyone even slightly mechanically sympathetic.(seen it done in bike shop  )
 
Quick & dirty~I've allways blipped the throttle with the lights on & watched for the flicker as the reg. kicks in & out.
 
FWIW, i suspect your regs not "dying" a long lingering death   , its most likely either DEAD or ALIVE.
 
May be as well to check your alternator windings & all the other wiring connections associated with the charging circuit as that burnt pin's telling you something.
 
Hope that helps, not sure it does.
 
 
 

 
Not done 10 mods yet, but i'm working on it...
 
1)Fzs1000 rear caliper really worthwhile IMO,(& looks cool) standard caliper is pants, my hack '91 xj600's puts it to shame.
Only trouble is finding one... i was searching a good while.
 
I'm sure i found the details on this forum, pretty straightforward, you just need to file the 600 caliper mounting bracket a little, easy job, which is more than i can say for bleeding the back brake once you're done! Don't say i didn't warn you.
 
2) while you're at it how about the fzs1000 drilled caliper mount bolts F&R? Look trick without spending silly pennies on titanium thingies.
