Want HOT hands?..It can be done!!! EDITED FIRST POST

[SERPAGS]

If all goes well, I should be installing 06 bars on my 07 sled, will post if affects clock at all. Happig tuning , Dan.

we are gonna do my buddys 07 with 06 bars too now....we just gotta get matt to find them and bring them up!..LOL


guys with 07s,ask around dealers and your buddies for their 06 bars!

thanks
dan

Yammy should pay you some royalties for figuring things out for them!
What do you want to bet that '08's will have this fix??

Yamaha would never sign-off on this "mod". A potential 131Watts/11Amps on high is extremely excessive and is not "idiot proof". This "mod" has the potential to damage components, even injure the unsuspecting. Yamaha would not take that kind of risk.

The 06' grips are ~2.2 Ohms each and wired in series. This means that there is 4.4 Ohms resistance in the circuit. Assuming 12.0 volts D.C. heres the math.

06' (Stock in Series)
Watts= Volts ^2 / Resistance, = 12.0^2 / 4.4 Ohms = 32.7 Watts Total.
Amperage= Watts / Volts, = 32.7W / 12.0 V = 2.73 Amps.

06' (Stock in Parallel)
R(parrallel)= (R1XR2)/(R1+R2), = (2.2X2.2)/(2.2+2.2),= 4.84/4.4= 1.10 Ohms.
Watts= Volts^2 / Resistance, = 12.0^2 / 1.10 Ohms = 130.9 Watts Total.
Amperage= Watts / Volts, = 130.9 W / 12.0 V = 10.9 Amps

i really hope this is the "fix all", cause i went thru 2 set's of the updated bars, switching them out, i thought i was going nuts, thought i had put them in wrong, couldn't get crap for heat out of either set, going to put the harness on my 06' bars and put them back on, thanks again, Dan

O.K. Guys one question. If the above info is correct and the system is drawing 10.9 amps on the HI setting. you can cut that # in half turning the warmers down to half???? and somewhere around 2 or 3 bars (1/4 or 25%) on the display would be what we've been living with on our existing high setting????? Seems like common sence but I thought I would ask? Thanks.

exactly or what about adding a resistor ???????

Like I said Dan I poured myself a frosty one, kept the '07 harness and put my '06's back on. Grips were hot at idle!!!! Had it on the stand and wound it up a little bit, and grips got really hot!!!! I can definately say running them at med. would be all you would need. Thanks again Dan.

Dan...I don't know you...but I'd be glad to...

I think you are an Asset to this site and your spirit of ingenuity and the generous way you give of your information makes you someone I'd be glad to call a friend...although I doubt I'd ever have anything you'd need or want from me...I'd be just as generous as you..

thanks for your info..very informative

Yes, Dan's a good guy. Funny, when he spoke the truth on DT, they burned him at the stake!!! The truth hurts!

Hello Hammer, you have my curiousity. Please go into more detail. Is the low figure the Amperage we were seeing with the old grips on HI?

btw..I might auction my 06 bars off on EBAY!! Sound like I'll fetch a good dollar for them!!!

Before everyone gets defensive about Series Vs. Parallel conection lets look at the facts. I'm the one who wrote the above post in another post about handwarmers. Now the reason I knew that the grips would get extremely hot is that we hooked my buddies (allblkviper) grips up this way. He bought the 06' grips and ends. We glued them on but didn't have rivets at the time (thought they would have come with them). The grips got so hot that the glue basically melted and the grip would twist. So I knew right away that the stock grips were not wire in parallel but instead series. Now will wiring the 06' grips in parallel hurt anything. Well to answer that your going to have to know what the whole system is sized for. That being the Controler the switches and the wires. I don't know the wire size off hand but I can tell you that the Max Ampacity of 18 AWG copper wire is 6-14 Amps depending on the type of wire used. That being said I think we can say that the system is not designed for 10+ amps. Now before everyone calls for my head, I think running the heaters below the half mark will reduce the chance of a system meltdown. The wattage is the same as the 06' series BUT the amperage draw is ~5.45, which is twice that of the series ( funny how the math works). So since the wattage is the same as that of the 06' "series" I assume that the half way setting is not a true half power if you are felling a significant amount of heat at the half setting. I will investigate this tonight with my Fluke meter. I have to agree with Hammer that Yamaha would never sign off on this due solely on the fact that the circuit CAN be overloaded. If something electrical were to fail on the sled I can bet you it won't be covered. I would suggest removing the jumper before taking it in for any service or warrenty work. Aside from that I not bashing Machs Idea it WILL without a doubt get you hot hands just remember what it is you are doing and make sure to educate anyone that rides your sled.

As far as adding a resistor, the issue becomes the size and capacity (wattage). Just a to big and hard to find item, then if you did find it were to put it, it's going to get hot so you can't just throw it anywere under the hood. What I am thinking is a double warmer. Take an old style element and wire it into the circuit. It may require a series/parallel combination or some tricky circuits to get it at the correct levels but it something I plan to look into.

I hope Machs system it works and shows no ill effects as I don't enjoy the cold hands either. I just can't get myself to ignore the math behind what is going on electrically.

On mine I still couldn't feel them (but im talking like -10 weather here). When I got the newer bars they still were not warm enough... so my dad put on a toggle switch that gives them more power to the warmers, works so nice you cant even hold on in -10, -20 weather racing down the road. But with the switch error code 81 will start to flash, and he can't get it to stop. But w.e they work like a charm haha

Got Apex RTX, I can't wait for the results.

Jim, what do you mean," no error code"?
