Handwarmer fix? Has anyone fixed with just a re-wire?

There must be a way. There are so many posts on this topic but someone must have found a way without changing bars, adding rehostats, more grips...

Either, paralell vs series or add a resistor or something?

Anyone?

These 06 bars are cold!!
 
I dont' know either, would love for for a simple rewire fix. I was looking at it the other day cause I'm sick of cold hands and I think all I did was switch the L & R harnesses cause if anything they got colder.
 
06 Apex/Attack rewire for handwarmers

Is this what the o7 sub-lead harness is actually doing?

This is how I have rewired my Apex. Not had a chance to test.

so you did this and it works ok? Looks like it takes the grips and puts them in series and powers them with only one side of the circuit. Looks like each has its own circuit in the original config.

did this work ok? Seems like it should..
 
this is what i did and it worked great :Rockon: get some expanding foam and insulate the inside of the bars,stick the straw end of the can in the hollow part of the bar and fill with foam. this way the heat isn`t disapated into the bars :Rockon: hope this helps you all out
 
Ill try that too.

Last nite I did the re-wire and took a 5 min ride I couldnt go very fast in my small field so I couldnt really tell. Plus it was -2f at the time. But I could feel some heat but the the rpms under 6 grand I dont think I was gettting much juice..

This a discussion going on under General Yamaha. He's created a fix and is marketing it.

I'm interested in the foam idea. Anybody else tried it yet?

Thxs.

David :yam:

Tnx David!

The sub-lead connects the early '06 bars in Parallel (They came wired in Series).
This will make those particular bars warmer.
Called the Rockerdan Mod, the TY user that came up with it.
Have not heard of ECU issues with it, many guys have done it, have heard of the clock issue, making me wonder also.
The ONLY issue I have at this time with it, is the lack of it being "foolproof" anyone messes with your handlebar controls, or you forget, (I hate having to remember things, just wanna sled! lol) and you can melt the grips right off your bars.

If I read the drawing above correctly you are changing the bars from parallel to series, this will make the bars colder yet.

The updated '06 bars and up, including the current ones, are already wired in parallel, you can't just change the wiring to get any improvement.
Foaming the bars will add a SLIGHT amount to the thermal mass, making the bars take SLIGHTLY longer to heat up and slightly longer to cool down, other than that, it has no effect.
Well... one effect, it will reduce the vibration you feel in the bars, but lead shot works better for that... lol

Mine is not the only solution out there, and not really trying to sell them with this post.
FYI: Sure I like having money to sled, but the big thing is for all of us to have warm hands, however we end up achieving that.
Will post anything I know about any mod I see, and be honest about it, whether that effects how it goes for me or not.
The big thing is, we end up with WARM HANDS, and don't risk frostbite!

Hope this helps! :-o
 
I was just thinking there is no pad over the bars/ riser as the RX1 has. This means the metal part of the bars is exposed to cold and gets transfered to the whole bar.... making it yet harder to warm the bars. I think Im going to connect up a hose to my coolant tank and heat the damn things with my hot engine water...

Hey that might work! :exc:

Hahaha!
Like the coolant idea! Just no control over the heat.

Know what you mean about the handlebar pad, it WILL help insulate the bars from the wind/outside world.
The foam inside won't insulate against anything, just the other side of the inside of the bars.
Unfortunately, the thermal conductivity and losses along the length of the bars won't change.

it worked for 3 of my apexs :Rockon: but im not riding in -40 weather. rock how come when i ride with my thin klim gloves pre foam insulation the handwarmers dont work ? if i wear a thick pair of gloves they work great? thats pre foam insulation. now i have toasty hands with the thin gloves. dont know why but it worked for us.

Can't tell you exactly, "placebo effect" maybe? lol (jk)

I do know that generally insulation (foam included), insulates between 2 temperature differences.

For example, the "R" factor of your house insulation indicates it's resistance to heat flow through the wall. (In or Out)
So if you foam your bars, it insulates one side, say the back of the bar, from the other side, like the front.
(This effect would be very minimal, because the thermal conductivity of the metal bars is so great.)

It IS very possible that it keeps air from flowing into & out of the bars, helping to keep them warmer by cutting thermal losses that way.
Another possibility is the air (prefoam) moving around within the bars convecting heat away from the grips to the colder parts of the bars.
With foam, it would basically eliminate this loss.
(That and you don't have to heat up the now gone air inside the bars.)
That's the only possible possible thermal benefit I see in using the foam inside your bars.

The way Doo does it, is to insulate the warmers FROM the bars, keeping the bars from wicking heat away from the grips.
(Again, thermal insulation is used to keep heat from, or in something.)
Doo does this by using cork as a thermal insulator between the grip and the bars.

Basically for the foam to make a major difference, it would have to be between the grips and the bars.
Any other positive effect would be very minimal for most people.

It is very possible that your hands were close to warm enough, but not quite enough, and this made just enough difference to be ok for you, and that's cool!
