"WOW!  She turns in super easy now that I have a nice firm tire!  The smaller handlebars may also be contributing to this."

No doubt, not having air in the front tyre is going to make for some heavy steering and a new tyre ALWAYS feels SO much better that that "piece of crap other brand" you took off.

I find quite the opposite between the Standard bars and the RS bars.
I find that the RS takes more counter steering pressure because there is less leverage with the shorter bars.

I totally agree with the RS (shorter) bars needing more pressure.  I've read where others have said the same... the shorter bars result in less "responsiveness".  I guess riding with that low/flat tire has given me an incorrect sense for what the taller bars feel like  :laughing1:.

I got my heated grips all wired up the other day.  Tie wrapped the control module and excess cables to the frame to make it look tidee.  I was so excited to turn them on to feel the warmth! 


* IMG_1697.JPG (59.07 kB . 768x576 - viewed 698 times)

Unfortunately only the left side grip was getting warm.  I waited and waited but while the left got warmer and warmer the right didn't.  I was so bummed.  Thoughts of how I would need to now uninstall them to return them, or what I could do to avoid or minimize removing and reinstalling.  Some of the reviews I've read for these grips did mention one side not getting warm or that they heated unevenly so I ended up with one of the bad ones. 

Decided to just lift the tank back up and see if anything obvious jumps out at me.  This is what I find...


* IMG_1700.JPG (23.13 kB . 768x576 - viewed 668 times)

Took the controller with cables to work and found that the terminal was never crimped around the insulation to provide any sort of strain relief.  Not even sure if the wires were even crimped to the terminal because there were no broken wires in the crimp.  I ended up removing both terminals, soldering the wires to them, and crimping the terminal to the insulation.  Reinstalled the controller/cables and now both grips get warm.  Yay!!  icon_cheers

I'm liking these grips.  The temp control is on the left grip so looks clean and easy to adjust.  5 power levels... the colors in the pics are a little off but you get the jist... (please excuse the MESSY garage!)

Those grips are purdy tempting for the naked bike, but heated grips ain't gonna make it much warmer.

Go back and change those zipties...black is what you want.  :laughing4-giggles:

Ha ha... I almost made a special trip to the hardware store to get some black ones but then figured they were under the tank.  I may still go back and swap them for black.  :laughing1:

It's always fun to get packages in the mail...


* IMG_1719.JPG (51 kB . 768x576 - viewed 627 times)

Took some time this morning to get the right hand switch controls swapped out.  First obstacle... how the heck do you get the main connector apart!  Ended up cutting open the protective sleeve to see what I needed to push.  Found the two catch releases on the two sides and managed to get it apart.


* IMG_1721.JPG (34.6 kB . 768x576 - viewed 632 times) 


* IMG_1724.JPG (35.46 kB . 768x576 - viewed 604 times)

Next challenge was how the heck to get that big connector past the forks and out from behind the headlight assembly.  I didn't see a way to do this without taking the headlight assembly off (at least partially)


* IMG_1725.JPG (36.69 kB . 768x576 - viewed 618 times)

Took the headlight shroud off to access the four mounting bolts that hold the headlight assembly to the forks/triple tree.


* IMG_1726.JPG (65.23 kB . 768x576 - viewed 615 times)


* IMG_1730.JPG (53.64 kB . 768x576 - viewed 604 times)

I just loosened the two bolts on the bottom and the top right (looking at the headlight), removed the top left.  This gave me plenty of room to get the cable out.


* IMG_1734.JPG (44.57 kB . 768x576 - viewed 656 times)

While I was at it, I got the switch for the four way flashers installed.  Mounting the switch to the dash pad was pretty straight forward.  Followed the old wire to the connector on the main harness and plugged the new switch in.  Only thing is the new switch doesn't have the third wire (and I assume no light) to light up the switch.  Not a big deal since it's pretty obvious that the four ways are on.


* IMG_1736.JPG (76.38 kB . 768x576 - viewed 638 times)


* IMG_1737.JPG (58.05 kB . 768x576 - viewed 636 times)


* IMG_1738.JPG (60.78 kB . 768x576 - viewed 628 times)

I'm not happy with the wire/cable routing around the handlebars... will deal with that when I swap out the left hand switch controls (coming from ebay) and the shorter brake hose.  Swapping out the cables for the short RS ones is probably something I should consider as well.

Old vs New... on my red bike


* IMG_1742.JPG (54.93 kB . 768x576 - viewed 611 times)

The old ones I can put on the blue bike cuz those buttons are in bad shape  (assuming I get it running).

I swapped the clutch cable from the Standard to the RS and there didn't seem to be excessive cable. I don't think I gots it routed quite right though. The throttle cable of the RS started not returning this week, so I'll gets to look it all over when I replace it.

The M&M's are only $60 with a free throttle cable!

That's hilarious!!  I've got enough bags of m&ms from them to open a candy store!  Ha ha... not really.  Only 6 or 7.  It's nice to have a source or two like them for parts.  I've got short cuts for Max BMW and EME and have given both of them a bit of business.

We had a nice break in the weather today so a group of friends went for a 60 mile ride.  The new handlebars are working out great!  Temps were in the high 30's to low 40's.  The heated grips were great!  But my thumbs were still a little cold.  Way better than without.  My fingers would normally be white and numb by the end of the ride and getting my helmet off is near impossible.  This time I could actually remove my helmet with no problem.

One thing I've been noticing for a while now is the smell of something getting hot somewhere.  Well today I found the source.  It started with the speedometer needle fluctuating back and forth.  It would move up as speed picked up but the needle wouldn't be steady.  So I check the forums and a few talk about spraying contact cleaner into the fuse sockets and sliding the fuses in and out.  So I did that.  But while I was at it I noticed a long brown wire that was loosely coiled up next to the battery.  It was connected to the engine but the wire insulation was showing signs of being overheated.


* IMG_1769.JPG (56.9 kB . 768x576 - viewed 534 times)

Glad that I found the source of the smell.  Will see where the wire goes and replace it with something more substantial and shorter.

I've seen that cable kit from EME while looking for other things.  Didn't think I'd be buying one (or two)  :laughing4-giggles:

Thank you for the suggestion, Volador!

When we needed a ground cable for the R65, my FIL just went to Napa and bought a pre-made one, I'm sure it was much less than $30. Just looked - $7.
That is what the ground cable on the RS looks like too, big flat connector rather than an eyelet.

So is that brown wire in the picture which ties into the transmission housing the primary ground cable?  I haven't checked to see where it leads just yet.

We don't know where that brown wire connects. What we do know is that screw at the transmission is the usual point of connection for the cable from the battery's negative post.

I'll have to dig around and see what the PO had going on.  I'll report back.

Yup... that little brown wire is the only thing connected to the battery's negative terminal.

Positive terminal goes to the alternator and the relay box (I'm assuming the starter relay)
