First Ride on GT

[1000 stroker]

First off, I could not ask for more out of this thing. Unbelieveable! As for the darting, not an issue. I have stock ski's that I shimmed and this thing is as stable as any other sled I have ridden. And this is with the stock carbides still. Not putting on new ones until we get more snow.

The rear shock is to soft for sure. I am over 250lbs. Going to need the bigger spring.

Stock clutching flat out works if tuned. Riding with many fast fast sleds and mine with stock clutching held its own. I am side by side with an RTX with us who has clutch kit and GYTRDUN exhaust and he is at least 50lbs lighter than I am. He also said, looks like all of this stuff isn't worth the money.

What is worth the money is the Hauck Fuel accelerator! I gained performance with small adjustments to that. I have not done the full airbox mod that I mentioned in a previous post yet. I am still running stock airbox with a minor mod that I came up with one night. I consider this Fuel accelerator a big plus and super easy to change on the side of the trail. Guys had said that my exhaust had a different tone to it than normal. Said it had a little more snap to it. It does! It sounds pretty cool and not as loud as the GYTRDUN kit. I love noise and have piped every sled I have owned, but that Hauck exhaust is a little to much for me. A couple swore my exhaust was not stock. It is. Bone stock. My exhaust does have a different tone. Must be from the small airbox mod flowing more air through.

Gearing: I went to a 23 and seems to work well. The RTX still had the 24 and he and I were tied together as far as we raced. Until he hit the spray. That added 5 lengths to the equation real fast.

The mighty Mach's: As always, they are fast. We had a bunch with us. Two on NOS, and a couple not. One with spray would'nt race. Go figure. The other didn't have studs in his new 128x13.5 hacksaw. With no studs I could kill him to about 80-85 then it was lights out. He came by me like someone hit my brakes. NOS is so cool.
Another non sprayed Mach ran real good. It had a programmer, exhaust (I think just a can), and clutching. He probably had a good 70lb advantage. I could holeshot him by a length, he would catch me by 85-90, and at 100-105 he had a good length on me. To me, that aint bad with a 150 horse stock sled with a heavier rider.

And last there was a modded ZR 900 who could not accept the fact that the GT was stock. I put $500 on the table for him to prove me wrong. He refused. It is a ported, piped, clutched, ZR900. It is a good runner. But he got his feelings hurt. He just had the sled dynoed this week at 173hp on a 45 degree day. So he too makes a lot more HP than me. The biggest compliment is when people refuse to accept that it is stock and it is. I love it. I have spent a ton of time making everything perfect on this sled and it always pays off. The little things that my buddies make fun of me for doing. They think I am just lucky and always get the good ones out of the box. Must be coincidence time and time again. LOL

Great job Yami on producing an amazing machine. I have been riding since 94 and this thing is in a whole different category.

By the way, this was all in Cadillac MI. Snow was adequate. We got our first 100 miles on.

I would be happy to share any helpful info that I have found so far. A lot of good info on this site that has proven to be helpful. On the other hand, I would tell people to be careful what you read and try stuff first. Skis are a good example. IMO, they work fine if you set your chassis up correctly. Even with the shitty stock carbides I feel like this thing works everybit as good as it should. Others will disagree. I am not saying who is right, I am saying try it first. Some people start swapping parts before they even try it. I almost did. Skis and clutching have almost been replaced about ten times in the past three months. It was hard holding off and actually seeing for myself. Now, I am glad I did. Saved me a lot of money.

Good luck

Im glad you like it..

If you geared it and added a fuel excellerator than its not stock anymore.. (the gearing can make it as much as 5 sled lengths quicker and ive heard the excellerator makes it half a second quicker in the quarter without any tuning)

My buddy who owns a stock zr900 and i have raced several times.. and it is very close.. with me only wining by 2-3 sled lengths each time... SO the mods you have done must have made a big difference to beat that modded ZR..

What is this fuel accelerator?? How does it work and what does it do.

 

[SledFreak]

So, share with us the little interesting things you have done to gain performance.

First ride

Interesting read.
Did you run at night sense the trails are not open yet?

I consider it stock. Look at grass drags, you can change gearing and jetting and still be in the stock class. You cannot say changing a gear makes it not stock. The only power adder is the fuel accelerator which according to Allen and his dyno, helps if you do filters, timing key etc. I have the accelerator pump richened up one spot, and the main jet richened 1.5. Not very much. For example, with a pipe and K&N's, the main is suppose to be richened 6-7 spots. So 1.5 is not a lot.

Call it what you will. Bottom line is this. You don't have to spend a $1000 in exhaust, clutching, and "stuff" to get an apex to run with or ahead of some fast high HP sleds. As far as that ZR900. It was off on RPM's that day so he will get faster. But that is kind of my point. Every other time we ride, his is too rich, or not pulling the RPM's, or watching EGT's, or,or or. Been there. Had a BB viper last year that ran strong when it wanted to but was an utter PITA. Blew up twice, not consistant, and I was always checking temp gauges etc. My GT is stock and will run the same everytime I get on it. Just solidifies my point of what an great sled this is. This is not to rip on any of the others. They are all great. I got beat my fair share yesterday. But never by any thing without a lot more HP.

Fuel Accelerator: This gives the ability to richen or lean the fuel curve as needed. Similar to rejetting on your old 2 stroke. You add air, you increase fuel. I bought it used off of ebay just to try. So far so good IMO. I am not saying that this is the fastest sled on the trail. But I will say that nothing with similar HP will touch this sled in stock form just tuned in. OK, if gearing and fuel aren't stock, then for less than the cost of a clutch kit. I have $200 in to the accelerator and that is the only mod money I have into the sled. To be running with 170-180 clutched, fast sleds with $200 spent is quite impressive to me.

No not at night. During the day. Trails open on the 1st. We were good to go. Rode from Bristol and over to lost pines area.

1000 Stroker: Could not agree with you more on the set up. My 07 ER is stock and I could not be happier with the handling. It is almost "telepathic" and easily goes where you want it. No darting, feels way lighter than my old SRX and RX-1. I am very pleased out of the gate.

 

[Mighty]

Very nice report.
The engineers that design these things know what they are doing.

my apex er didn't dart very much with stock carbide runners,when I put a more aggressive carbide on(6 inch shaper bars), it darted bad,but would carve the corners much better.

Now when you say you were set up... How much did you do to your suspension? You commented you would need a big boy spring, were you bottoming out? Did you adjust compression or rebound on the shocks during the ride? Is the limiter strap at the factory setting? Just wondering how heavy the steering is... These obviously were'nt groomed trails, so the steering was good in the loose stuff then? Thanks for the report, I was hoping to see one on an 07 GT as I wondered if Yamaha addressed the to soft/ bottoming condition in the rears...

 

[RED800]

1000, are u studded..and u say stock clucthing works if tuned correctly? my rtx is stock but i did go to 23 top gear and plan on studding...i gonna get the brgstrom triple points becuz my rtx darted badly last year(i did shim them)..if i can save on not buying a clucth kit,that would be great....i have 650 miles on it so far....

 

[welterracer]

STock is considered anything strait out of the crate.. (anything you add to the sled is consisdered a modification)


Saying it is stock.. is like saying its stock but i added nitros.. LOL

All that matters is that is a great sled,, that really runs great out of the box..

 

[1000 stroker]

I am studded. I used 1.340 Roetins with Woodys angle plates. Double backers in the middle, and singles in every other outside row. I didn't get holeshotted all day. Pretty good for a stock clutch set up to leave that hard. I do think my weight helps with hole shots.
I did set my suspension up for me. I set the ride height as per the instructions here. It rides great, but yes, I did bottom a couple times on not so bad bumps. One of those big whoops that catches you off gaurd will be bad with this spring. I was hoping I would not need it, but I do for sure.
Welter, I agree to disagree. LOL I know what you mean, and your right. But with that being said, nobody is stock base on that theory. Nobody does nothing to a sled. If for no other reason that to tinker with it. I look at it this way, if the ZR9 I refer to had only a power breather and rejetted, I would not say I beat a modded ZR9. Enough said. I follow what your saying though! Its a matter of opinion and everybodies is different.

As for the straps. I did adjust those out. My first thought was to pull them in, but when I set it on a flat surface and tried to get everything balanced and flat, it made more sense to let it out. I have it in the top hole. All the way out. I have my transfer set right in the middle. It leaves like a bitch. Stays pretty flat, and takes off. If I get on the back end I can stand it on end when racing if I try to, but if I stay right in the saddle of the seat, it launches really nice.

The steering effort was suprisingly pretty stiff. I need to work on that. I have the preload real soft on the front to help keep it flat in the corners. And I have the rebound set high on the front. The rear is set right for ride height, I left the compression setting hi for the whole day because it felt so soft. And yes, I did play with the rebound dampening and ended up around 10 clicks higher than stock. One trail was actually groomed. Most were not, but one section was. It seemed ok on all terrain. I will say, the only place the skis were not that great was in powder. They don't float at all.

I just "modified" my airbox some more and have a filter kit that I am adapting. I took some pics and will post them when I figure out how. Its not done as I need two more filters to complete it. But I took pics of two of them on. I took it around the yard without the filters on and it required a fuel adjustment on the Hauck controller which tells me its getting more flow. More flow means more power. I didn't do any RPM check yet since I don't have the filters on. I didn't want to get carried away. I just did a couple of hole shots. Gosh these things are fun. BTW, I am using the stock airbox lid with no modifications. Kind of my own stealth kit.

Trenchdigger3: Yes, that makes sense. Once you change one element of a sled, others need to be adjusted. My SRX was like that: Cold air kit and clutch kit led to 240 studs requiring 10 inches of carbide, less ski pressure, etc. I am just enjoying the balance of an unstudded sled for a change. A riot to slide the corners, etc. Just need to be real careful on roads, etc.
