Are you running a stock length chain at 114 links  Cosmo?

No. 112.

Thanks Cosmo. Going to make the change since most of my commute is in the higher speeds. Ordered a JT rear 43t sprocket today and have a chain tool to drop a couple of links out.

If you get stuck for a 19 front, Yamaha xjr/fj12/1300 will fit.
May need a big chain breaker, found an angle grinder most useful.

I may as well do it, as I'm gonna get blamed for it anyway.

So I checked my front and it is a 18T.  I ride a good bit two up with the wife and wonder if a 19T front is worth it.  I'm not on the highway for long stretches and only use the bike on the weekends, but I do have a 1500 mile trip with lots of highway (just me) at the end of this month.  Will a 19T make it harder to do the slow speed two up stuff?  I'm guessing a little less rpm on the highway has to impact MPG's at least a little?  I'm sure the back is stock as well, but it seems like a 19 up front is probably worth it for highway cruising. 

Is there a big difference between these front sprockets:

So the front sprocket nut on an '05 Girly is 36mm?  I don't have a 36mm socket, but thought the nut had some wiggle to it.  Is it held in by force, meaning torqued to a certain spec or is it tightened to a certain point and locked in place by the flanged washer?  Just wondering if I need to order a 36 mm socket for my torque wrench or hand tighten with adjustable pliers.  Should I replace the washer?

I just changed mine to 19T  :XXsunsmile  If properly mounted it is torqued to 130Nm  :icon_eek:
So jou really have to order (borrow) a 36 mm socket (a black one) and a great deal of force!!
If not to loosen, you certainly will need it to lock the nut.
IMHO if not dammaged you can reuse the washer.

Going the other way,  because I have a sidecar attached to my 885i I've dropped the front sprocket to 17 and increased the rear to 53 (the largest I could fit without changing the chain).

At 4000 rpm I'm traveling at about 50 mph but I'm still managing to get the best part of 45 mpg (UK)

Thanks Marc.  Just ordered a 19T JT sprocket and 36mm socket  :eusa_clap
