All steamed up!!!

Would a frogskin on the back side of the hood work? anyone tried it? I do like Stingrays reverse fan trick but my fan it not on much to begin with.

I thought the same and wondered that before I tested. But, it must come on once in a while as there is no longer any steam coming out of the Viper. Unless I missed something that you guys testing may find, always that possibility even though I test a lot before I post.

I thought about the frogskin on the hood but something came to mind, part of the fan reverse idea came from ice forming on the radiator stopping air flow. I suspect, but have not tested that frogskin may make this icing worse. BTW we have not had the radiator plugged since we reversed the connector....the fan comes on and clears the radiator.
 
Frogskin must go over the big black louvers.Not Under them. No snow or ice will stick to it. It falls right off. It may look goofy on a Viper.

On my radiator delete Viper I put the frogskin under the louvers sandwiched between the plastic, looks great but does fill with snow.
 
Yes that is what they do. On cat it actually looks fine. But ours have a cool shape to them I think it would look crappy but it will work.
 
I cant believe how poorly this seld is Built. I have owned 5 Yamaha sleds, 7 Yamaha Motorcycles, 3 Yamaha Quads and 2 Yamaha Power Generators. I have always been a big Yamaha fan like I bleed blue and I hope this is not the way Yamaha is going in the future. I cant say I hate Arctic Cat I have owned 3 Arctic Cat F8's and still own a 09 F8 and think its a great sled. I am really thinking of cutting my losses and jumping ship to try a ski doo it cant possibly be any worse. My riding buddy has 3 ski doos and loves them and I kinda like them to. I just love Yamaha for the motors and I just thought it was a match made in heaven, Arctic Cat chassis with a Yamaha motor what could be wrong with that? Apparently a lot. Arctic Cat really needs to let the engineers at Yamaha to have more input on how things need to be built and fit and finish. I hope a Yamaha rep reads this and really evaluates what is going on with the partner ship between Yamaha and Arctic Cat. Just my 2 cents.

Yeah a couple of small growing pains with this model, no where near the disaster the 2007 Phazer was though....or the 2003 RX1 with engine rings that would not seat. Yeah there are a few things I fixed but ya know what? My buddy with a late model ski doo is looking at the 2015 MTX now after riding my Viper. So yeah the stock Viper hurts in the clutch department, but the clutching on the cheap thread fixes that. Some other minor issues that I will happily put up with to not have a sled with s dead engine (I have a ski doo rev with a blown engine cluttering up my shop as I type this).

I am thrilled with my Viper, but to each his own.

If you need help PM me your number and I will help you get it where you want.
 
Another day of riding butt deep powder and NO steam from either of our Vipers. I jumped off my sled so girlfriend could take a pic...no steam but no radiator either. Oh, no steam on hers with the radiator fan reversed.

Well I just did the fan reversal and wired in a switch.. Fired the sled up, let it get to riding temp (158-163*) and turned the fan on. It was able to hold the temps to 160-163* while idling in the garage at 60*. So at least now I can stop and don't necessarily have to shut the sled off every time we stop/wait for ppl to catch up.. Just flip the switch and wait ;)!
 
was out yesterday pulling heavy seigh on groomed trails and pulled off trail to stop in to about 8 inch of snow no steam. went to take off and spun track for a second and stopped but sled only move about a foot . a couple of seconds later steam started to come out the vent in dash. So i tried this again several times and same thing every time.
In my case i am convinced the track / exhaust is creating my steam problem .
My question is has anyone blocked the hole in the tunnel ?? or used something to seal the header area better to contain steam ??

The snow is used to cool the exhaust, I would be careful covering it as I am not sure you wouldn't melt the gas tank if covered.

When idling and waiting for people to catch up would the stock fan not keep sled cool?

Or... Were you shutting it off so fan wasn't pumping hot air into intake?
 
Nope, it didn't seem like it even slowed the temp down (climbing to 200*).

I would always have to shut it off.
