I got a '02 MXZ 600 Ski-Doo that went in for its 250 mile check up last season. The first ride after getting it back from service, the throttle trigger seemed tight and gave me a whopper of a sore thumb. The previous rides I didn't feel a thing. Could the dealer have tightened the throttle cable so much that I would feel excess resistance even at moderate throttle? (not wide open) Any idea on how to fix this with no major effort on my end? How about a rubber banding the throttle wide open for a few weeks to stretch out the cable some before the season starts? I assume the cable is completely sealed so there is no lubrication I can do.
Any comments would be appreciated. And no I am a big strong guy with paws for hands so don't tell me to toughen up lol...

ez thorottle lever bout 30 bucks

Karl,
first thing ask the dealer. another you can lube the cable by oiling it, squeeze the throttle and touch the cable with oil then let off the throttle. do it at both ends a few times.

i have a two stage throttle that i love and will be putting one on my new sled.

2 stage throttles are the best, i know a friend cut alittle bit off the spring on the carb.

Darn guy, you beat me too it. You took the words right outta my mouth. Oh well, just TOUGHEN UP. LoL

Before you do anything, there is something for you to check. One time after I had my sled in for some service, the dealer didn't put the choke cable back in the right spot when they put the air box back in. End result was the choke lever was a really tough to move and the choke was actually half on. Anyway, take a look to see if the cable is in the right spot and not excessively bent. Go into the dealer ship and look at some other sleds to see where the factory cable routing is. Your's should be like that. If it isn't, that is almost guaranteed to be your problem. Short of that, you'll have to check the whole deal, carb, cable, throttle lever. Check each individually. I'll bet it is something simple like cable routing. Let us know!

Check for bent cables, lube it up at both ends, if that doesn't doo it then I always cut a few coils off of slide return spring. I usally cut them in half.

I found that all I had to do was reposition the throttle. I was having major problems with a sore thumb within minutes. I twisted the throttle down farther on the handlebars, and now instead of having my thumb out a mile, I just have it in a more natural position and can slide it back and forth instead of out. It made all the difference in the world.

For what it costs, I'd suggest trying new positions before you buy more crap.

Thanks fellas. All good advice. I'll try repositioning the throttle lever to see if that helps. I called the dealer this morning and he told me there was little I can do about it. He said the carb springs is what's giving the tension, not the throttle cable. I am sure that cutting some of the carb springs off would lessen the tension but as a dealer, I'm sure he would not suggest that. I did pick up a thumb support over the summer to try but I doubt it will help much.
Thanks to all for the responses.

Modern snowmobile cables are Teflon coated. Lubing them is a No No! Trimming the springs is O.K. but if you take too much the slides will float at certain hieghts making erratic control of the throttle and also lessens the throttles ability to close when icy.

Either pop[ for the EZ throttle or get a game-boy. lol.


:hallo9:

First check for bent or kinked cables if they are OK. Then disconnect the cables at the carbs and trace which part of the system which is adding the resistance to the trigger? (cable,carbs,etc.) With only 250 miles on it sounds more like some improper assembly to me?

Did he tell you this after looking the sled over? You said it was fine before it was serviced, and then it was different after you got it back, if I understand what wrote correctly. This says to me that the cause is something that your dealer did while servicing the machine. My hope is your dealer said that there is nothing you need to do because he would look after it as it seems to be related to the time it spent in his shop. I have always heard that it is bad to lube the cables because the lube will only collect any grime and make the binding progressivly worse. If you have flat slide carbs with a rack type set-up then the throttle pull should be very easy. Disconnect the cable from the carbs and see if you can isolate the binding to the cable or the rack mechanism. Make sure the dealer knows if he did something wrong, or sloppy.

No I only called the dealer, I did no take the sled in. He has not seen it since last Feb. when they did the check-up which right after the throttle seemed tighter. He basically said there is nothing I can do about it and he has the same problem sometimes. Also mentioned that other sled buyers sometimes say the same thing. He certainly was taking no fault for anything they did and acted like this is common.

thats what scares me, i would want some springiness still just in case they iced up and didnt have enough compression to close the slide again and then your stuck wide open.

i learned something there. !!!

This dual stage throttle intrigues me, is it an aftermarket item, or OEM?

How different does it look than a single stage throttle? I think my 96 FZ is only a single stage and I was looking at easing the strain as well, perhaps by cutting a couple of coils on the carb springs.

Well.......I know that Polaris makes one. It is basically a two stage device that changes the pivot point part way through travel. If you don't have a Polaris, it should still work, just make sure you are getting the right one for your carbs. They have different pull lengths for 34mm, 38mm, and so on. You will probably have to splice in the polaris kill switch too.


Or.......Check with you branded dealer, and see if they make one for your sled.
They ARE nice.

Also make sure that the position on the handlebar isn't what is causing your fatigue, you might be able to relieve your pain by simply twisting the control a bit.

This is kinda scary. It sounds like your dealer screws things up somewhat consistently and believes it is not because of something he did wrong. If it was fine before he fiddled with it and it was not working properly after, then he did something to it that negativly impacted on the operation of the vehicle. Does your sled have round slide carbs, or flat slide carbs with a rack style set-up? I think you have to determine if the binding is with the slide in the carb body, or in the cable. Give us some more specific info and we'll see if we can be of more help, because it appears your dealer is not worth much.

I have no idea what kind of carbs I have. But I do have a buddy who is very mechanical with his Yami that will take a look at it. If I find out I'll let you know. Thanks for the help. Yes my dealer didn't seem too enthusiastic about giving me a answer. Unfortunately getting a trailer to take it to him is a big hassle for me. Otherwise I'd do that now. I'll see what happens on my first ride this year. If it's still a real problem then I'll have to take it back.

It sounds to me like your carbs are not sliding freely, I would not drive it until its been checked out, for fear of bending or breaking somthing inside the carb.

the two stage throttle that i had on my sled was one i bought as a kit from ski-doo and oh what a better feeling.

it doesn't look out of place in fact you have to look to see it is different.
