Some more 2011 info

Yamaha did not take the conditions into consideration with the Mono RA dial. I finally took all of mine out and blocked the tunnel.

yep my cable broke the first season.....you can simply take cable out but leave plate and Remote dial all in place so it looks nice,no need for plate.

good idea but hard to do with the icy environment it lives in......some of yammies ideas dont pan out.

dan

mine broke this year also, crap set-up

Mine broke the 1st year. I had the recall done & it was fine ever since.

good to hear

Mine broke every year, 4 times total. Yamaha did cover it under YES each time except this year, so I did not pay for another one. I put on alot of miles in Quebec, and the suspensions get much more ice than snow in them up there compared to the States. I believe it's the ice chunks that take them out.

That damm shock wire on my GT has broke 3 times too. Looks like the Exup will be sealed from the elements better.

Power Comander has a relay or somthing for the removal of the exup servo on my FZ1

I, for the life of me, cannot figure why anyone would be excited about it having an exup valve!?! That would just be something else I would have to gut out if I bought one.

x2 remember the good old SERVO operated POWER VALVES on the '98 700 SRX! 1 more thing to service and up keep!!!

Yamaha's patented Exhaust Ultimate Power Valve (EXUP) monitors engine rpm and adjusts exhaust flow for maximum performance at all rpms with no flat spots. This system also optimizes fuel economy and reduces emissions.




Here's an excellent tutorial on adjusting the EXUP valve. http://www.cartestsoftware.com/fz1/exupmaintenance.html

Cheers!Err on the loose side when adjusting the cables. If they are the slightest bit too tight, you'll get the 7K error code. However, if you keep them a little loose, you'll be fine. I've had two bikes with EXUP valves (1995 FZR1000 & 2001 R1) and in over 80,000 miles between them I have NEVER had any issues with the valve or the cables. Keep them adjusted properly and at each oil change, pull the EXUP cover off and shoot some WD-40 up the cables and you'll be fine. You'll then be enjoying the awesome low end grunt that the EXUP delivers.


sounds good

I had a 2006 R-1, and am fully aware of the exup valves purpose and benefits on a stock bike. My point is that...#1 The r-1 engine turns alot more rpms than the apex engine. #2 You also use alot more midrange, (rpm wise) on a bike than you ever do on a sled. It is common to "lug" a gear on a bike through a corner (say 6000-8500 rpm) then accelerate out of the corner to redline. You are using the midrange in this case and the exup can be a benefit. On a sled, the engine does not stay in the "midrange" long enough for the exup to really benefit imo. Look at your tach on your apex the next time you leave a corner and see how fast it shoots up to 10000-10500. Cvt clutching doesn't allow the motor to "lug" under hard acceleration. If you are spending alot of time in the 7500-9000 rpm range, you are either trail cruising and just maintaining speed, or in serious need of some clutch help. Either way an exup system would not benefit imo. I believe there are alot better ways to "wake up" the apex engine. Going up 1 to 1.5 compression points would be one for starters. So you have to run premium fuel now, I think most guys would accept that for a give or take 10% increase in power? I would. Just my 2 cents.

They have bumped the compression hence the sticker

PRESS RELEASE

All-new Yamaha Genesis engine offering for 2011 snowmobile lineup:

* An all-new 1050 cc turbocharged Genesis engine – debuting in the
2011 Apex Turbo – will deliver significant improvement in torque, an increase to an estimated 210 horsepower and better fuel efficiency, enhancing productivity and further strengthening its position as the class leader for design and performance.

* Industry-first single-sequential turbocharger with double-sided compressor wheel delivers fast throttle response along with the volume of air boost needed for maximum power.

Combining two turbochargers in one package
The single-sequential turbocharger – an industry first – is key to the new Yamaha Genesis engine's performance. The unit has two compressor wheels driven off one turbine impeller. This approach combines the benefits of a single inertia wheel – faster response without lag –
with the thrust of a larger turbocharger, with the ability to force more compressed air into the engine for more power.
The engine's smaller exhaust volume combined with a corresponding smaller intake volume and smaller turbocharger creates a system that is quicker to boost, more responsive and better able to deliver horsepower and torque, especially at the low end, when the customer demands it.

The turbocharger includes an advanced variable nozzle turbine, which enables variable vane pitch angles, driving optimal turbine power to achieve optimal boosting levels for all operating conditions. The single shaft ensures the transition is seamless. The unit – compact in dimensions – is uniquely center-mounted on a patented pedestal low in the back of the valley instead of hung off the block, which helps balance the system and aids NVH characteristics.





















That would be nice wouldn't it?!?!?! Guess we just have to keep dreaming. Sounded good though didn't it?

 

[rightarm]

I could choke you right now JK nothing wrong with a little fun

Damn that sounds good alright!

 

[apltx08]

AAAAAAAAAAHHH!!!!!!!

Here is a video, dont know if it has been posted before. It has a nice sound!

I I JUST ABOUT WET MYSELF DUDE !

That sounds suspiciously like Fords new 6.7L Diesel turbo, I wish it was true though...
