Bought a 2010 Apex LTX GT

[rangermaxx]

I just thought I would introduce myself on the forums, I have been reading for a while and looking at sleds and just gathering information anyways I picked up a 2010 Yamaha Apex LTX GT with 1600km on it from a local yamaha dealer. I am getting pretty excited for snow to try it out its killing me to look at it and not be able to ride.

I have found out a lot more about the sled when I got it home over the last few weeks after reading these forums for a while. I noticed on the rear heat exchanger the studs were rubbing a little ;but the previous owner had already fixed this issue by welding another piece of aluminum to the tunnel protectors or so it appears.

I also noticed when I pulled the side panels off that it has a ulmer clutch it, is there varaitons on this clutch kit ? Is it a huge benefit over stock? Anything I need to know about it or check out?

Is there anything else I should know about this sled, I just want to have a trouble free season. I owned cats before this yamaha so I know the Z series cat's quite well but I dont know anything about the 4 stroke

Thanks Guys

Nice sled. Yes there are a couple variations of ulmers kits. But it's definatly a improvement over stock. You have the updated from skid arm (w arm). Stick some cr10ek plugs in it. I like to pop my speedo bearing seal off every season and pack it with grease. I also do my jackshaft bearing. If it doesn't have them already, put a set of pilot skis on it or aftermarket skis. Makes a big difference in handling. The pilots make the sled steer as well as an 11 with power steering. Set your front springs so the a arms are almost parallel to the ground. Then adjust the shock damping to ride preference. The revalve on the mono shock is well worth it but yours might already be done. Unless there's a company sticker on it, you won't know unless it comes apart. So I would put some miles on it and see how it feels to you. Try to not get to addicted to the torque lol

Good luck with your 2010 Apex LTX GT, I have the Black one same model. Forums here are the best. only issue I had with mine was handling, took me awhile to get it right with stock ski. I have gone to the new tuner ski this year so I hope it will be even better now! I have about 188 pics in the rear. The only place I have pic rub is on the exhaust cross over pipe( few marks) mine came with the rear cooler extra pcs from factory. Check your rear suspension sag, mine was set for a 140lb rider and me being over 220 wasn't good. Ski alignment is a must also. Front set up is just like copc said. run your track a liitl loose and hyfax wear should be good. stock gearing and clutching was good out of the box with my only primary spring change for me. Ulmer clutching is a good kit with good rep. check my posts history for my issues and solutions found here or ask any questions and I will try to help you. Good luck and post some pics!

That sounds like a good idea I will pop the bearing out and grease it, might as well throw some new plugs in it, they dont look like too much fun to get at though lol. Im not sure what kind of skis it has on it, I will take a pic and upload it, I will definately look into upgrading them though sounds like a must have.

I will look into adjusting the rear suspension sag although I am not sure how to do that yet I will be browsing the forums for information.

I added a few pics of the clutch if anyone can tell me anything about it or if you need more pics let me know? The one thing that looked odd to me is there is a stack of washers on the secondary is that normal?

I had an 2007 LTX (Attak) seeing that your from Ontario ill tell ya this now. The ulmer clutch will slow you down on top end..hard to beat stock set up for top speed. It will pull harded, but you'll loose on top if 10-30mile top end runs are the norm

I had pilots on my LTX and they sucked BaD. They push like hell in snow... Hard pack trail there ok. But terrible in the soft stuff.

And leave the plugs alone, you'll never fell the extra half Hp

The sag you talk about cannot be fixed completely with any adjustments or kits. On the nytro forum there is a "star suspension kit" that helps alot which is something ill be looking in to

Sag check

Ranger, Here is a pic of how to set you sag. ( Rider weight on sled) For me this was the best improvement on ride and handleing. Not sure what Yamaha apex means? Anyway here you go.

I'm with you. After messing around with motocross bikes and sleds for greater than 20 years, I have yet to see any great advancement in increasing power or speed from aftermarket stuff. From clutch kits for sleds to reed valves for 2-stroke bikes to pipes for 2-stroke bikes, nothing has ever made a difference. So forget the clutch kits, changing pipes, changing spark plugs, they only add to the dream meter.

I have seen a big difference though how you can make your toys handle from aftermarket stuff. Different skis, different carbides, revalving suspensions can all make a difference in the way these things handle.

Congrats on the new sled, just go ride it.

I've got the identical sled; one piece of for sure important advice is; get the new Dupont sliders, makes a huge difference. I was wearing out hyfax in good snow conditions in 400 - 600 kil. The Duponts are showing no signs of wear and no track clip wear signs at all. I had a couple of extra wheels before this but burnt the rubber off the wheels on hard fast lake runs.
Like the other posts said, flip the covers off the two bearings and see how much moisture and grease is in there and probably dry out and repack.
Handling; you will have to decide; I have set my suspension to how my preference but have not changed skis because I dont have a problem with the handling; to each their own.
Be aware of your studs especially should you be riding and bottom out.
All in all though a great maching.
