07 apex gt upgrades

[Macheater]

Yes there is a club in Thompson, and a few others are skattered around the area.
My boss is the president of the Parkman Polar Bears club.
Not sure if the Thompson area has much of a trail system. I met a few guys from that club, some years ago in Austinburg. They had ridden over from Thompson. Don't know how many back roads they had to take to get there.

Sled has less than 3000 miles and all stock im an adrenaline junkie and dont like to go slow and am not afraid to push the sled

JILLIONS of opinions is RIGHT! So here is mine. I am would describe myself exactly like you did younger, strong, don't care about 'cruising' I like to push the sled and me to the limit (when I responsibly and safely can, I have two kids so not a teenager without a care in the world endangering others so no safety police please ). Look at boost and rear suspension right away. To me a apex on boost, WITH a proper rear suspension turns the sled from a docile trail cruiser to an animal that tries to kill you, and that is what I love!

Your SOL on the rear suspension called the AD Bovin ZX2 this is an amazing skid that allows the ole girl to dance over moguls and actually make them fun! I had a 06 GT skid and it was very comfortable but I couldn't push it 50% as hard as I can with the ZX2. Unfortunately they do not make them any more. If you see any used scoop them up or let me know! I am spoiled with my ZX2 but if I had to start from scratch I think I would look at something procross derived with a hygear reavalved for performance. You want the front skis light. Fast M20/king air, etc is all about comfort and being able to steer so little transfer more for sit down riding. Get something more aggressive that will allow you to carry the instant speed a boosted apex is capable of and not bottom out and wreck stuff.

For boost go MPI SC if you ride tight trails - again unfortunately they are out of business too so look out for used. Go turbo for high speed lake/UP rail road bed running.

Lastly get the Ergos set up. Taller bars, MTX throttle cable, longer brake line, go high at least the MTX risor at a minimum and I like about 2-3" above that. Move them forward (tilt) so when you stand your leaning forward. Ditch the GT seat in favor of the RTX or MTX seat (or ditch the factory heavy weight seat all together and go lighter weight). I am 6'1" 220lbs and when I sat on the GT seat with comfy foam I thought my knees were going to get destroyed and I have good knees! The MTX seat was an amazing upgrade almost like adding 3" of foam to the GT seat (which is another option if you can't find a MTX seat). I do about 50/50 stand/sit. The seat is a must for me. I can't even ride a stock apex.

Boost is spendy so do it last but trust me first pull you will shat yourself and wonder why there is any other sled made. I'm sure I will start a debate on which is better but to me my tuned SW is a slug compared to a mild 10-11psi head shimmed SC apex. Go turbo apex and SW isn't in the same league. There is something about the 4 cyl spinning at 10-11K rpm and the gear reduction to the clutch that just makes these things FLY! I raced 300+ hp sleds and if they beat me off the line flew past them at 60mph like they hit the brakes. Non-apex people think the sled is fat, old, and for the trails only. On boost they become the ferrari on snow and soooo hard to beat. Best of all still reliable, lots of maintenance in the off season but turn key once snow flys!

Good luck and enjoy modding the sled, its so easy to make it your own!

I believe that AD still sells replacement parts for that suspension. I wonder how receptive they would be to reproducing a small number for a group buy. I would be in.

No rails though I would love to recreate it. Problems is you would sell about 5 LOL. They are definitely a cult following and never took off in the MTX world because at 53lbs just too heavy. I had a design to take mine down to 45 lbs with aluminum shafts, less wheels, carbon rear wheels, etc. At that point you have a $4k skid and I would just go with the all carbon fiber one. Really wish I could get the rails though. I ate through one a little and it still works to get hyfax on but I wish it was new.

Where would b a good place to look for a used mpi super charger?

 

[RobX-1]

If a turbo or supercharger doesn't pan out, another option would be to add a clutch kit, ignition module and power commander and do the air box mod. I run @Srxspec aka Ulmer Racing's clutch package and setup which included the ignition module and power commander and his map and his air box modification. I always though Yamaha left a lot on the table in regards to clutching so at a minimum, I always added an aftermarket clutch kit to all of my Yamaha's. Of course you have to address traction which is why I also run Stud Boy's Super Lite Pro series backers that act as an additional paddle. Rolled my own with the RX-1 clutching piece mealing it rather than purchase from a single vendor but took time and effort as well as a lot of researching of this forum to see what was working for others. However, when it came to the 08 Apex and Nytro as well as the 18 Apex, I opted to go with Allen's setup and from my experience, his setup was spot-on and runs strong.

With that said, if I ever did go with a non-naturally aspirated modification, it would a super charger. Just would be nice if the company you went with was still in business.

How do i find out about the ulmer racing setup all that u mentioned?

I gots to be honest here.
Doesn't sound like our new friend RC does enough miles to go crazy here.
My advice is based on 300 mile days with some trails that look like you're looking down a shotgun barrel filled with snow & love.
At 5000 miles per year there is plenty of things to do to this sled.
If he's struggling to find trails, and does 1000 miles, i'm not sure spending $5,000 on go fast goodies is where we need to mis-lead him.

I'll restate my first assessment here.

Dial in traction & handling
Ride
Get back to us

Once you're hooked, you'll be spending money Hand Over Fist & setting up trips to the big stuff.
We can help you spend money, just most of it may be wasted at this point.

[RC Apex]

Oh in hooked and want to do big trips

 

[Rtbo]

WRP seat and a lake effect riser were my favorite upgrades on my apex.

Agreed. It's the same question I've been asking myself for years. How much dough should a person dump into a 14 yr old sled that's worth 3-4 grand.
Especially when your not getting enough seat time to justify the expenditure.

 

[maim]

i tend to tune all of mine in steps if i need to add parts to break up the cost. the 16 was the only one i did not as i grabbed 95% of the stuff i wanted for it as i was having trouble getting some of the peices.

i would tune the suspension 1st as that affects the handling and traction most. then tune what you want it to do from there or makes it easyer to ride. for me it was bar riser usually and then i would get into skis on most of them.

This is probably the best advice, go ride fall in love with the sound, and take good mental notes what you want to improve. My first 4 stroke experience was on a RX1 stock and I about filled my shorts, then once I had nitrous, shorts filled again, then SC, then TC, now I'm working to TWIN charge my apex. (MPI SC with a Impulse TC feeding it!). I sometimes forget the first ride and how that is what started the addiction and loyalty to this model of sled.
