castlerep said:The reason for the lower octane is to allow the the engine to run hotter.Why? Emmisions! Lower octane burns slower and allows heat to build up. High octane has a fast burn which is cooler.( run your hand through a flame at a fast pace vs. a slow pace which gets hotter?). The reason for running the engine hotter is it runs cleaner. This is why cars have catalytic converters to build up heat (rumor has it that eventually sleds will too). I have heard that those doing fuel remapping are finding more horsepower by actually riching them up. and running cooler. I would Have to believe Yamaha has these things leaned out as safe as they can for emmisions. I know it does not answer any fuel mileage ?'s but at least the the reason for the octane rating
You have your info reversed. Low octane fuel burnes faster than high thats why it's more likely to cause detonation. The faster the burn the hoter the burn. High octane burns slower thus burns cooler than low octane.

I was thinking about this on my drive back from Northern Wi yesterday. What this site needs is some kinda of indicator near each members name. Something perhaps that would indicate there age,riding style. normal riding conditions etc... The reason I say that, is because i'm 44, ride the trail systems, always lead the group and ride aggresive. So if I say I only get 12MPG, now you kinda know why, but if I was say, 75 out for a sunday ride rarely breaking 40 mph and said I got 20MPG you could believe it and know why! I got 12MPG on one tank and close to 16 on the next. One tank it was light out and I had zero beers the next it was dark and I had 3 beers. Like most engines the throttle controls your fuel economy. This indicator system would help in alot of posts. Some guys say the GT corners flat with no inside ski lift, Well, once again if you are riding UP trails that are 4 cars wide with big sweeping turns or riding 5 MPH because you are 90 years old ya it's flat. But multiple s-turns 90-180 degree in the woods with a trail 6 -10 feet wide, forget it!!! If you ride hard it will lift.
Ya gotta love the internet though such a valuable resource!! Oh! no offense meant to anyone that does ride slower or is 90, just making a point that everthing is subjective to alot of factors!!

I really wanted to love the 4 stroke, because that is what it had going for it and especially why I snow checked it....
I'm not brand loyal, but Yamaha needs to copy the very forward riding style of the REV and lose 75 lbs...
As I said, I really wanted to like the sled.. It sounds like your one of the few that have been on a REV prior to going to the Apex. For me, in the 300 miles I had it, our trail conditions were pretty bad here in N. Minn. I did put alot of time into suspension setup, etc. I do know what I'm doing. Ultimately, I found that I was going to have to go to aftermarket ski's, which I don't think should be required on a new sled, and then after playing around all winter I may still have a sled that does not handle as great as my REV did.. Then if I'm not happy, I lose $3000 to snow check a new REV.. I did the deal now and lost $400 in the whole process.
Yamaha has many great things going for it. I can feel the extra weight on the front end though. Before I rode it I was about willing to bet I wouldn't, but I would've lost that bet. The overall handling is slightly quirky, and does have some inside ski lift. I know this is a big improvement for a long time Yamaha rider, but I feel is comparable to moving back to the ZX chassis from the REV. I knew that going into the deal, and was willing to make that compromise, but there ended up being too many compromises to keep me on the GT. Fit and finish is better than the REV. Quality is better. I think there are more features for the money than BRP offers. But, I don't think it is rider forward enough, and the cg is too high. When you move forward on the seat, the tank is too wide, as well as the seat being too slippery and just not right. I agree the GT is a great sled. The 4 stroke is really fun and much better than I imagined. Exhaust noise is a bit loud after a few hours, and I think it should be routed to exit under the tunnel. My comment on gas mileage was when I checked it on a 140 mile trip in rough conditions, averaging 20 to 40, with short bursts faster where conditions allow. Someones comment about "not breaking it in right" - I followed the manual with the heat cycles and rpm recommendations. Someone asked about types of riding and age - I'm 43 and have ridding for 38 years. I'm a pretty aggressive trail rider but keep it down some compared to the racer wana be's on the trail, as my 14 year old is always with me on his REV 500SS. I've raced both grass and water for many years in the 90's, and also have a Haydays 1st place trophy for trail stock 800 at Haydays in 1994. So yes, I do have experience, and also can set up a sled.
Overall, for "me", the REV is a better fit. I can ride one handed when meeting others to signal to others how many are behind me without putting up with the GT's darting. I can cruise along at 40 and look at the scenery, even if the trail is somewhat rough. I couldn't do that on the GT. Maybe I will get towed in someday - maybe I would have on the GT... Maybe if I kept it I would have gotten it dialed in and been very happy - a lot of maybe's.. I just wasn't willing to gamble on that, sold it at a slight loss, and moved on. I'm not brand loyal, and may be on Yamaha in the future. I do get frustrated when people are so brand loyal that they only talk about the good in their brand, and seem to forget about any problems. Overall, winter has been too short lately to spend alot of time working on the sled, I'd rather be out riding. Have a good winter - see you on the trails. In case your wondering, I do carry a tow rope - maybe for me, maybe for someone else...

I have to make a post to this...I just have to.
I can live with 13-15 mpg on a 150hp sled that will last for 30000 miles or more. When I go out my goal is not to worry about the mileage. Its to have fun and ride my sled...as I do when I ride my ATV. I could care less what the MPG is...now if it was only getting 5 mpg I would not be happy but I would still do the thing I love the most.
I feel the same way when I drive my boat...I bought a 225 hp FI boat that can suck the fuel as well but we love to be on the water...to ski , joy ride or what ever.... Just my 2 cents...may not be worth much but enjoy life my friends.

Guys that are getting 20 MPG must be riding like old ladies. I have a 2006 attack as well as my buddy. Now riding with him we absolutely fly. I'm clutched and he's stock. He got 12.6 mpg and I got little over 11. Like I said we fly. we ride as hard as we can the whole time we are out. In order for me to get 20 I would have to ride at a 40 mph pace.
AS far as ride quality goes My attack is the finest machine I've ever owned. Coming off a 03 136's RX-1 I can tell you this sled flat out eats the bumps and corners like a dream. It has zero inside ski lift "Zero". As far as it feeling heavy I can tell you that it flat out doesn't. I've ridden REVs, Fire cats, Vipers, SX's lots of them. I can run this sled through the twisters as hard as all of those sleds.
I think guys that bought the GT looking to run it through Moguls or bigger bumps bought the wrong sled. the Attack was and is the way to go if you ride any where that has the ability to go from flat groomed to 1 to 4 foot bumps.

We don't ride like idiots. We like to ride hard. the only way your going to get 20 mpg is riding 20 to 40 mph. I can't ride that slow.
I'm glad I don't care about fuel milage. Anything better then 10mpg is good in my book. If I can go 100 miles per tank I'm good.

Ive been riding 23 tears, tere are a few people that say I ride to fast, Its just EXPERIENCE thats all I can say.Then they rode my old RX-1 ,thats highly TUNED. They loved it,infact they bought them. ATTACK coming shortly!!! like previously posted mileage is at low and moderate speeds.The more you use the gas the less mileage!!

Huge BS call here. I highly doubt that the GT gets 13.5 while Rev gets 18 ridden in the same conditions, ridden the same way.

apex weight is right in there with the Mach Z and Fusion.

REV VS. APEX
I know that my $.02 means zero here, but reading this I had to reply. Over the weekend I invited a couple of SKI-DOO guys up to my place. Normally camp is a Yamaha dominated place , but two friends have REV 800 's. We rode Saturday through really rough trails, and yes they both passed me on my GT which is still not set up for the rough stuff. On Sunday I invited one of the to try my GT for about 10 miles of mixed condition trails. As I got on the REV 800, it was my first experience on one I kinda liked the riding position. Once I got it up around 80 I could not keep the thing on the trail. Talk about darting!!!!!!. Thinking it was his set-up I allowed the other guy to try my GT and I rode his 800 REV. Same thing. It was work keeping it on the trail. When we got to the bar both REV riders loved the GT and had zero bad to say. They thought the smoothness, power and overall handling was way better than they expected. I think I converted them. We are all going to Canada in a few weeks. I'll report back on fuel consumption.

Don't know where this is going but what the heck! I owned A Rev Renegade I thought was a Good Ride. Last year I had a Mach Z which was fffastt but rode like a dog. I dumped the Mach Z for a Warrior,it was a big improvement. This year Attak is freaking fantastic, by all accounts a superior ride to all of those sleds. I rode my wifes 05 GTX touring yesterday and while a good ride,can't compare to the Attak. Just my opinion, and I could be wrong. Now, the handwarmers and wheels drive me batshit! studdog

i just got back from munising and i rode with a buddy that has a 800 rev and i ride an attak with about 750 miles on it now and we were pretty even on gas at almost every stop, the best i got this weekend was 12mpg. there was alot of loose snow conditions with icey corners and pretty rough trail unless we ran into the freshly groomed stuff.

I'm on this forum because I snowchecked a GT! I was trying to gain some insight! I bought it, and then sold it for the reasons stated. The Apex is not going to get great mileage. I got 16 with the REV last weekend. Just facts! Now I'm getting angry because you're the big BS'er here. Are you so blinded by your brand you can't understand that others are equal or maybe better in some areas? Why even bring up weight of the Fusion and Z - The REV is 75 plus lbs less!

Tork, its not BS...I get 13.5 on my GT and as good as 14.5...so its the truth but my point has been posted and I really dont see what a rev rider would post here...if you like your rev, go drive it and may I suggest try a Doo site for your support and not here...is that so tough to understand.
