On a recent trip to Door county my recoil broke, No problem we weren't that far from where we started so we started her up with the spare rope around the clutch and made it back. I took the recoil to the dealer(excellent dealer) and they rebuilt it. The mechanic who usually will tell me anything I ask, said there was a c-clip that broke, I told him I know, I had half of it with me. He said I must find the other half because it could be in by the flywheel,magneto and mess everything up if it happened to be in there and got lodged. I took his advice got the flywheel puller, popped her off and found the piece he was referring to. Put it all back together- the flywheel, recoil, etc. Everything was back together but the exhaust which was off for access to the recoil assembly-I'll call it. We ran out of time the day we were working on it, So I just didn't put the exhaust back together, Which means I did not run it after we put it back together, just pulled it to see if everything was spinning as it should when you pull the rope and it was. Well last night, the night before I am supposed to leave to go up north, I go to put the exaust back together, sealed her everything was perfect. Choked it pulled it three times and she fired up as normal. It only ran for about 5-10 seconds,backfired and killed. Never got it started again, only thing it would do is backfire if we were lucky every 10-15 pulls. I think there is a problem with the timing but I don't know if you guys can help me it would be appreciated.

By the way it's an 2000 mxz 700

I wish I could help out Steimy.It finally snows and the sled is broke.I feel for ya brother. http://www.snowmobileworld.com/forums/iB_html/non-cgi/emoticons/confused.gif

Same here. http://www.snowmobileworld.com/forums/iB_html/non-cgi/emoticons/sad.gif

hey, sorry, I don't know why you can't start but I wanted to share that my pull rope came out on me after only 250 miles on my 02 mxz700. * Dealer covered it of course but its still a pain to haul it over and back to get it fixed.

Have you checked all the obvious like spark, gas in cylinders, fouled plugs, etc? *If you have the shop manual there are some simple electrical tests you can perform with a multimeter to tell you if your ignition generating coil (magneto) and trigger coil are working corectly. *Let us know what you find... *Good luck!
BTW *Those Ski-Doo (or should I say Rotax) recoils are nothing but junk in my opinion. *Everyone is having problems with them. *Mine has broke 3 times in 4000 miles (2001 MXZ800)

i read in my manual if the d.e.s.s. is not on tight it will back fire like that!

Is your gas on? *It's stupid....but it's possible. *Like the other guys said, did you try all the simple things? *Good luck with your sled.

Steimy,
Did you get the "KEY" back in when you put the fly wheel back on? *Also, check to see if the trigger coil may have been bent or the gap opened to far. (I think you should *have a trigger coil.) *The gap should be around .018.

msimpsom, that's exactly what we thought happened, the key sheared, throwing off the timing.

1. Gas is on
2. I have spark in both plugs
3. Key is still intact

I called and talked to the mechanic again and he said there still might be a small piece of metal in there grounding out the magnetic, that would not allow the ignition to work he said.

I'm going to try some things tonight to see if I can get her going, I'll tell you guys what happens, thanks for the help.

Hey horsecollar, *drive that thing into a tree and get insurance money.! * http://www.snowmobileworld.com/forums/iB_html/non-cgi/emoticons/biggrin.gif * Then its a done deal, so you can get a Firecat, *you've been talking about!! http://www.snowmobileworld.com/forums/iB_html/non-cgi/emoticons/mad.gif j/k

Steimy where exactly in Door County were you I live in Gills Rock a hour north of Sturgeon Bay. http://www.snowmobileworld.com/forums/iB_html/non-cgi/emoticons/smile.gif

We unloaded in New Franken and rode all the way up to Egg harbor, I think it was, I remember going over Kangaroo lake. We didn't quite make it to Gills Rock.

SLED UPDATE: WE pulled the flywheel off again, cleaned everything up real good and made sure no other metal pieces were inside, put her back together. Just for the hell of it did a compression test- 25psi WHAT the F#ck! Did it with the exhaust on also-same reading. Just to make sure we tested my buddies mxz 600- 160psi. Think a seal is blown because the pistons, rings, everything else is fine.

Would a sled not start and backfire(every 10-15 pulls) if the seal was blown- cylinder to case gasket?

Your cyl gasket wouldn't cause low compression thou it would make it hard to start. How did you check the rings and pistons? thru the exhaust? * low compression on both sides is an oddity. Only thing I can suggest would be to check your head gasket to see if the machine is losing compression into the coolant. While pulling over or once it backfires have someone keep an eye on the coolant tank for bubbles. Pull the heads and check the rings. If they're good , go deeper.

Did tou pull the jugs off to look at the rings? Bad seal won't loose compression. Both sides the same? Lost a set of rings on a 00 700 on the dyno. Everything looked good til we pulled the jugs.

Had the same problem with an old Formula SL. *The only way we could get it to fire at all was to put gas in the cylinder. *With that low of compression, it probably is having trouble pulling or sucking enough gas in to the crank. *Let us know what happens. http://www.snowmobileworld.com/forums/iB_html/non-cgi/emoticons/mad.gif

Well, the top end was ripped apart last night, the pistons and cylinders both looked very good. The rings were a little sticky. Went to the dealer and picked up new rings, gaskets, o-rings,etc. cleaned her up. put her all back together. We did a compression test- 155psi. so we have compression now and I think everything is good in the top. It still won't start, It just backfires-LOUD! The mechanic I talked to mentioned the center seal on the crank and the water pump seal causing it to backfire like that. Guess he'll find out this week, because I'm done F###ing with it, I'm takin' her in http://www.snowmobileworld.com/forums/iB_html/non-cgi/emoticons/mad.gif

Had something similar happen to me on a Honda 750Nighthawk after I dropped it once off its side stand. Damn thing would crank and backfire once in awhile. Check all the electrical I could with help from the sevice manual. Only thing could not check was the magneto itself. In the service manual it said the magneto was none servicable and non checkable. But if the bike had fallen over, chances were that the magneto had taken a hit and de-manetized itself. You can do this with almost any magnet by a sharp blow to it. The magneto still felt has though it had strong pull. Not wanting to spring for the cost of a new one, non-retunable, until I was sure, I took one off another bike and *the bike fired right up! Put my magneto on the other bike and it wouldn't start.
Is it possible when you removed your magneto it got a hit, changing its magnetic force lines? Just a thought.

did you use a air gun to blow out any debri around the flywheel?

No it never took a strong blow, nor was the flywheel dropped when we had it out. Yeah we blew it all out with my buddies airgun and sprayed some elecrtical parts cleaner in there and wiped it all down.

Sounds like the stator coil #### the bed.. they do it all the time.. my 00 has had two. I take it there is no spark/weak spark?

Steimy,tell Scott to hurry up and get it done so we can ride.I assume you took it to Robs. http://www.snowmobileworld.com/forums/iB_html/non-cgi/emoticons/wink.gif

Please let us know when you find out what the problem was. *It has to be electrical.

I'll be workin' out in waukesha tomorrow so I'm gonna tow it to work with me and bring her to Rob's after work. Scott is awesome,eh? Very helpful mechanic.

Steimy,he used to work in Oconomowoc down the road from me.It was an auto shop.Then he moved on to Robs.He is very helpful and tells you how it is.Robs became dealer of the year in part because of him I would say.

I'll agree with you there horsecollar, My sled is in his hands now, I have no worries. Except how much it might cost http://www.snowmobileworld.com/forums/iB_html/non-cgi/emoticons/confused.gif

Yea,I guess if you are dealer of the year you can charge whatever you want, * $ 70.00 an hour ouch. http://www.snowmobileworld.com/forums/iB_html/non-cgi/emoticons/sad.gif *http://www.snowmobileworld.com/forums/iB_html/non-cgi/emoticons/sad.gif *http://www.snowmobileworld.com/forums/iB_html/non-cgi/emoticons/confused.gif

Well, I found out why she wasn't starting- The stator was pretty chunged up from that c-clip rattling around in there, It was replaced total parts and labor around $300, I could had lived with that.

But no, When Scott got her started it was grinding and knocking so he shut it down right away. Said it sounded like a bad rod bearing, and went on to talk about everything else that might have to be done to it.

To make a long story short as of right now, I probably won't be taking it home for less than $1900

Hey, Mxz7 Remember that post when I told you my recoil broke and it wasn't the end of the world- I lied, You do not even understand how pissed I am right now, there is snow everywhere now and my sled that up until now has never had any problem at all whatsoever is basically a piece of junk. I still owe money on it and I can't see spending almost 2 grand to get it fixed, I don't know what I'm going to do yet. Their going to talk some things over tomorrow and call Bombardier and see what happens. I let you guys know what comes out of it.

For right now I am DEHORSECOLLARIZED!

Sorry to hear that news Steimy.Can't beleive that happend.I feel for you brother.It is unreal how much money it costs for major engine work on a sled. http://www.snowmobileworld.com/forums/iB_html/non-cgi/emoticons/sad.gif Just plain sucks it happend to you.I wouldn't feel so bad if it happend to a guy like Paul Y.lol http://www.snowmobileworld.com/forums/iB_html/non-cgi/emoticons/tounge.gif

I would let you use my wifes sled this weekend but we are bringing it up as a spare(one of my buddies has an old cat) http://www.snowmobileworld.com/forums/iB_html/non-cgi/emoticons/confused.gif

Scott says he wouldn't know exactly what was wrong until he split the cases on the crank. I gave him the ok to do so. I had more time to talk with him today about what was going on. Worse case scenario is a complete rebuild of the motor- $1900 at that include the stator that was already replaced.

He says somethings not right when he pulls her over, like a bad bearing in the crank, or something even in the top end. But to know for sure he had to look at the crank.

Some good news is BOMBARDIER offered to pay for 50% parts on the crank if it's bad, because of problems they have had with my sled year. I have 6000 miles on it so they wouldn't fully cover it, and I don't blame them.

With the 50% on the crank the most it will be is around $1500

I'll find more out tomorrow

your lucky you made it 6000 miles on the crank. My crank bearings were shot at 2600 miles. I rebulit the whole engine for 400.00 (using the old crank.. just new bearings) pistons ect. While it was torn down I'd call Bill Cudney and get his head/shim/piston kit for it. It wakes the sled up big time. http://www.snowmobileworld.com/forums/iB_html/non-cgi/emoticons/biggrin.gif

I think I might have part of that C-clip in flying around in mine...I just replaced it and never gave it another thought! Geez..I better check it out...

Rocketman, you replaced what? your recoil? did it break?

Just purely out of curosity, did you hear the noises it made when running, or were just told about it?http://www.snowmobileworld-s2.com/forums/iB_html/non-cgi/emoticons/confused.gif *I have a buddy who took a mach in there earlier this year for a tune up, and wound up needing a new engine, crank bearing was supposedly bad...... seems kinda weird. *Dont get me wrong, Robs knows their stuff, but from what I have seen, they are not afraid to charge you for everything, regardless if you need it or not. *List price for a stator is $174 (parts only). *I bought one not to long ago, took about 45 minutes to change.

GC, When we were pulling it over trying to start it, it didn't feel right nor sound right. We couldn't keep compression. I was told by the mechanic that the pistons were collapsed (skirts) and he would recommend replacing them. The sled has 6000 miles on it. The crank also has a 2 bad bearings, one being a rod bearing. All together including the stator and a full engine rebuild-new pistons, crankshaft, seals, gaskets etc. will be around $1500

Hey Steimy, sounds like it is time for a new ride http://www.snowmobileworld-s2.com/forums/iB_html/non-cgi/emoticons/biggrin.gif

Wish I could get a new ride, At least it will be like a new ride when I get it back.

GC- I looked up the stator on a site that has on-line microfiche it went for $196 and some change, He charged 1.5 hours for labor, $70 an hour so 196+135 and tax come out to right around $340, Where is Brillion?

Maybe prices went up a little since I got mine, I guess it was a year ago already (Jan of 2001 I replace mine on my 00 mxz 700). *

Maybe an hour and a half is right for labor, dont think it took me that long, maybe my memory is failing. *I only thought it was about 12 bolts/nuts to take the stator out..... flywheel pops right off with a puller. *Who knows, I wasnt timing myself when I did it I guess.

Brillion is just east of Appleton, about 12 minutes. *I have friends down in the stoughton/cambridge area, who always go to Robs. *Just thought it was strange to hear of 2 people, you and my buddy, who were 'surprised' to find out that their engine was dead. *It could happen I guess.

Look at the scenario- Mach z had alot of crank troubles, and most of there other triples at one time and so did the mxz 700, From what alot people are telling me I am lucky I got 6000 miles out of it. Like I said mine didn't sound or feel right when we were pulling it over. Maybe while they were giving your buddy a tune up they heard something that wasn't right that just a rider wouldn't listen for. I could do alot of this work myself along with my buddy who is a mechanic and save some money, but I would just rather them do it, because I want it done now, and I would probably only save about $300-$400. If I were to do it I would still have them do the crank no matter what, and we would put together the top end which they are only charging around 2-3 hours anyway, I don't have any clutch alignment tools or anything either, anyways you seee what I'm getting at.
