Buster696 said:Yes.. that is true... it's a pain in the A$$ to change helix on an XP. And, even when you attempt this, there is something in the secondary (had this explained to me) that may break, if you are not careful. That's just crazy...
--Buster696--
How is that??? How would you get the secondary off or what makes it so you have to change the jackshaft? The helix is a major component of clutch tuning. I would think it would be easier to change!! WTF???? LOL!!!

Also, after reading the arcticle, I'm not sure they even clutched it, unless I miissed that part on dealer prep.
LOL!! Even after Dealer Prep the Doo was still slower than the STOCK APEX!
I'll take my extra 100+ lbs any day over the Flimsy Flyer!

Jonathan,
I rode this weekend with a couple of my buddies. My Apex, another Apex, and an 800R. We got out on a groomed road, lined em up and put a beatdown on that 800R. In truth, they were very close but we were able to get the upper hand most of the time. That 800R is a pretty nice sled though. Rode good and had some good mid and high range power. The 800R motor does not have that seat of the pants feel like the Apex though. By the way, that throttle on the 800R pulls like my old Polaris 700 triple. My thumb was worn out after about 5 minutes! The throttle pulls hard and you need to be right to the bar to get the power out of it.
I guarantee that an unbiased sledder could ride both sleds back to back on a groomed road/trail and they would pick the Apex every time. On the bumpy stuff, they would probably lean toward the 800R. The Apex motor is addicting.
P.S. I did put the smackdown on him with the Juice a few times

Simply awesome!!!
I saw an 800XP and an Attack riding together this weekend! The XP looked light! It did a big rear wheel wheelie!!

Yea,
That 800 will be pretty sweet if set up right and broken in.
By the way, I have that new ZX2 skid and it transfers weight way better than the stock skid. Even with it set up at medium transfer, I can pull wheelies on my Apex even off the juice
I actually have to lean way forward to keep the skis down when conditions are right!

Why doesn't YAMAHA send a dealer to the shoot-out who is an exclusive Yamaha dealership, and not some dealership who has multiple snowmobile franchises, and who is obviously partial to their other brands?
Back in the 70's, my family ran a Yamaha snowmobile dealership and Yamaha always sent us technical bulletins for the sleds.
I remember Ronnie Ouimet from Adams, Mass. who had factory backing, and he knew how to set up his sleds. Where are the dedicated Yamaha dealerships that are True Blue Yamaha fanatics?
A dealer prepped sled should be faster than a box stock sled.
Maybe Big Moose Yamaha should read all the tips and set-ups that Yamaha riders on Totallyamaha are using and stop being a disgrace to the greatest snowmobiles being manufactured.

I think Big Moose is O.K. You have to remember dealer prep changes are limited to clutching, suspension and airbox changes.
Stock Apex clutching is very good for a stock motor. Airbox mod might get you a couple of HP but nothing noticable. Suspension changes can make a huge difference but not always.
Anyone on here that races will tell you that sometimes adjustments you make that you think will get better results are actually worse. I race asphalt and also know many people that race asphalt. We make clutch and skid adjustments all the time and find ourselves getting worse...not better sometimes. Sometimes it takes 5 or 6 adjustments/runs to get any improvement at all.
I think all of these dealers had to "guess" what was going to work better. Some were right, some were not.
The 800R showed a lot of improvement because their stock clutching is way off. They were able to nail down the clutching and see some major improvement. Yamaha stock clutching is very good right out of the box.

hhmmmmm.... I agree a little bit of what you are saying, but this is the third year with the Apex. I believe they know what works and what does,nt. They certainly knew what made the 800R happy.

I heard the 800R had the clicker on the wrong clicker spot outta the crate...so they said!! Simply putting it too SPEC #3 (I believe) gave them the difference!

Believe me, my buddies 800R is running about 8400-8450 rpm's stock. I'll bet the dyno graph shows the 800R making 15 Hp more at 8000 rpm than it does at 8400 rpm. We'll know when the dyno graph is made public. If that is the case, clutching is a no brainer. The Yamaha makes the most HP around 10,800 - 11,000. Ever notice where your Apex is revving at full throttle? Right around 10,800 - 11,000.
I think track conditions, temperature, and wind direction make a lot more difference than most people realize. Throughout the day, the track gets slower/softer, the temps rise, and who knows what the wind is doing.

The way I read it, they added tip weight AND changed the clicker.. I'm not familiar with ski doo clutching though.
" The solution was to put more weight in the primary and make the easy adjustment to the TRA clutch from position 6 to position 3."

I believe the 800R makes it's most power @8150.... From what I'm told, just dropping the jet 3 sizes is a major wake up. If the clicker was truly on 6, than it was a sand back. The TRA clickers allows you to adjust the rpm by + or - 100RPM. That would be the reason for the 8450.

Exactly, I from what I've read, STOCK IS #3!!!!

That makes me wonder if the dealer sand bagged it to make it run slower on the stock run. If they did, that is a shame. Or, maybe they thought it would run better on 6 and were trying to cheat???
