lucky_7 was right, the bulletin was for the Phazer. I don't know what the Phazer fix was, but they both use the same switch & bars - maybe it would apply to the Nytro also?

From the power source, voltage was higher than from the grips, so he believes the problem lies inside the harness in between somewhere, which will involve another day of poking and prodding, ughhhh
Anyway, I've put more than enough into it already both time and money wise, so I'm just going to wait till Yamaha comes up with a definite fix for it before travelling 250 kms again and be the guinea pig unless they want to cover the costs.
what kind of meter was he using? I believe the voltage for the hotgrips is PWM. if he was using a cheapy analog meter, you would get fluctuating voltages. I think you need a true RMS Digital multimeter to get an accurate reading.
I have to figure this out as well, because I FROZE my fingers last weekend and I don't want to go through that hell again. fingers were completely numb for several hours.

thanks for all the input guys im going to be contacting my dealer today

one thing i did notice was how small the stock wire's are for the stock grips,compared to the aftermarket hot grips..

just got back from the dealer and as i suspected they checked the resistance of each grip and the voltage supply at varied rpms and all was within spec. they are now waiting for word from yamaha to determine what to do . i have a feeling im gonna be getting the shaft but hope not
on a side note they did tell me that on the nytros and the phazers the grips dont get power at idle or if the brake light is activated( brake lever squeezed) i dont know why they would program this into the system when there is always going to be a battery thus battery voltage present
dont mean to vent just getting frustrated knowing that this has been an ongoing problemm with the apexes and now two years later still a problem with the nytros

Im not surprised theres fluctuation, because on my last ride in similar temps as the 3 rides before, my thumb warmer got old school hot at times and the grips actually kept me from getting cold---not warm but I didnt freeze for once.yamahaguy said:

This weekend my grips wprked great for most of the day. Then My left grip quit working and my right grip worked fine. I shut the machine down and it appeared to reset the grips? Now my left hand was on fire when the grip was 2 bars from low? My thumb warmer was always hot?n I will be going to see my dealer for this problem and I will post what they say about it. Other than that the sled performed flawlesly. I was with an 08 GSX800R and when we were going approx 30 mph he pulled up on the side of me goosed it, then I goosed it and left him. I know he would get me top end but the mid range on mine is awsome. OH by the way my build date is lucky #7.

well i just picked up my rtx from the dealer and no repairs were made to my handwarmers te response from my dealer was that yamaha says they have only had afew complaints of this problem and they will look into a fix but in the meantime just jeep riding it and if they come up with something theyll contact me. i for one do not find this to be an acceptable answer or solution. if i took my new truck to the dealer and told them i had no heat they dont say aw we only had a couple other complaints just keep driving it and if we find something well contact you
no they would stand behind there product and find aresolution to the problem. sorry to vent but this just sucks paying 10k for something and the manufacturer just blows your warranty problems back in your face.
ive always ridden yamaha and have purchased four new sleds in the past ten years and this is the worst answer i have ever had from yamaha
THANKS FOR NOTHING!!!!!!

Thats crap! They (Yamaha) follow these forums closer than we do. Besides cold hands isnt a new Yamaha problem anyhow.yamahaguy said:

At this point I'm just glad my handwarmers work, my left boot isn't wet, and my a-arms seem to be in place after hitting some solid waterbars (very hard on a few of the hits). My time is comming perhaps?

A fix will come.. however might not be until the season is over.. But everyone complaining about the 10K they paid in the states shouldn't feel so bad.. that same sled in canada is 13K with an equal dollar...hmmmmm doesn't seem right.

Dont let ALL of the other issues take anything away from how you really feel about the poor handwarmers. The "hot grips" on my 80 Exciter work waaay better than my Nytro's but I wont be comparing the two sleds any time soon.Unluckydiablo said:

Sorry for taking so long to reply BLUEBALLER, but I believe he was using a top quality meter, at least it looked a lot better than the one I was using, plus this mechanic likes to problem solve, he didn't stop checking it over unless he was on the phone with Yamaha's head tech. Yamaha is VERY WELL AWARE of the problem, and they have received numerous complaints on the issue, but I'm done being the guinea pig until they come up with a definite fix, just too costly for me both time and money wise to travel to the dealership all the time with nothing in return. Good Luck guys...

My dealer talked to yamaha about the grips and they said there have been a lot of complaints about them and the problem is when the electric fan kicks in it robs voltage from the grip warmers causing them not to work as well. They are working on a fix now and there will be a bulletin out I don't know when but they are working on a solution.

Well if that's the case, the fan must be operating all the time, because mine never once got hot while at the dealership when being tested on the stand, and they surely don't get hot when riding in -10C or colder.
