Look at the trail that its running on.  Thats like ski resort grooming.  

Only grip about the stickers is that the MACH Z is written to small.  But the flames look good and the writing font is cool..

I like the flames....If I keep my sled I just might have to update the decals....I think they look cool.

I agree that Mach Z could be a little bigger though.

Hmm.

That 3 into 1 header is suspicious.

I was under the impression that the only 3 cylinder left a ski-doo was the Mach. Are they comming out with a high torque 800 like the old F-III 800's, or is this just an old picture?

It seems strange. If they had to take an old picture for the web site, they could have at least taken one for a mach.

Yeah, wonder where they got that picture from.  The description of the mach still says triple/triple so we know that they didn't change that.  Maybe that's a special REV engine in the pic?
?

the engine is still in the CH3 chassie in the picture becauses you can see where the frame comes up on the pto side where the shock bolts up

Good Eyes.  I could have looked at that all day and not noticed what you just pointed out.  Heck, to be honest I still can't tell

Thats just an old pic of the Grand touring SE engine.  THey had that pic for every Mach Z year.  Its still triple/ Triple.

I find it funny how the Sled that is soposed to be the most out dated is the most talked about.  I'm into sleding a little more than most, PiranhaZ28.  I also have a problem of not keeping my sled stock or being the slowest
Do you have any thing done to yours PiranhaZ28

ACM,

Mine is stock engine wise, but I have a few "dress-up" things on it.  Everybody is dissing the flames on the new Mach, but I think they look pretty cool and I just might get me some.  

Do you have a Mach?  What year?

I'm happy with mine when I get to ride it, but there always seems like theres something wrong with it.  It's crazy.

Then after a winter like this it's even more depressing if ya know what I mean.  

Well, we just got some snow today....maybe we'll get more for the weekend.  My sled is supposed to be good to go now so I'd like to give it a try.

Take care.

Man, a bunch of stuff.  Some of it may be considered minor, but since I'm not smart enough to fix my own stuff every hour in the shop counts.

When I bought it I had everything gone through and replaced stuff that needed it like a couple boogie wheels and some bearings, and sliders and things like that.  Then I drove it for about 3 weeks and a ring let go in the center cylinder so I had to have it rebuilt.  I had new rings put in all 3 cylinders just to be on the safe side.  The parts weren't really bad, but with labor it wasn't cheap.

After I got it back I kept blowing belts.  I figured that the clutch was out of alignment so I could understand.  Wasn't really a problem with the sled itself.  It was the end of the season and I couldn't get it into the shop for a couple weeks so I figured I'd just take it easy for the last few weekends of the season and it would be okay to take care of later.

So this year I figured I was being a good sled owner by taking it in for a nice preseason checkup.  I had the carbs cleaned, and the clutch aligned, and I also had it gone through again to make sure everything checked out.  They replaced a few things that were regular maintenance items so it was not really a bid deal.

Well I had trouble the first ride of the season.  I fouled a couple plugs, and it ran like crap the whole time.  It was skipping constantly, but gradually got better throughout the ride (never totally went away though).  

Anyway, I think I went out for like 4 rides total and fouled a plug each time.  It didn't kill me to change them, but it is annoying and I knew something wasn't right.  There was also still a bit of a skip over bumps and corners as well.  

Anyway, I took it to a shop and the guy thought it might be the killswitch so he changed it.  I asked him why it was fouling plugs and he said that he checked a bunch of stuff and couldn't find anything off.  He said "well, a big sled like this is bound to foul plugs".  I explained that after my engine was rebuilt last year I put on about 200 miles and never fouled a single plug.  Then he started questioning my warm up procedure.  Yeah right.  Anyway the day I picked it up he said everything seemed good as far as not skipping, but couldnt' totally explain the plug fouling.  He said it was probably how I was letting it warm up.  I told him that I gave it full choke when I started it, then immediatly switched to half choke and when the RPM's dropped back down I flipped it off (all of this only took seconds).  I said then I usually let it idle for a few minutes to let it warm up.  Then he said well, instead of letting it idle, take it out and go easy with it until it gets warmed up.  Fine, I figured it would be worth a try.  I left his shop and took it out in the field across the road.  First corner I went around it skipped!  That made me mad, but we were going to the races (sleds) that day so I had to get going.  My parents house is about a 1/4 mile from the shop....when I pulled into their driveway I fouled a plug.  That really made me angry.  At the end of the day when we got back from the races I had fouled 5 plugs in 40 miles.  The temperature was in the 20's, so it wasn't warm, but wasn't cold either.  

I brought the sled back up to the guy and he said that he had a bunch of other stuff to do and couldn't get to it.  I called a ski doo dealer and they said they were booked for a few weeks so I took it to another shop (which is a yamaha dealer).  He found the clutch side RAVE valve sticking and he got that working right, but it was still fouling plugs in the center cylinder.  It was in his shop for 2 weeks and he finally found a bunch of bare wires (in three different spots).  He fixed those and then took it for a ride and fouled another plug.  After talking to a few different mechanics he put a BR8ES plug in the center cylinder and tried it again.  I guess he put on 60 miles with no problems (must be nice, my longest trip of the season was just over 50 miles  
 ).

Anyway, I picked the sled up and tested it out at my parents place.  Plenty of snow, but in the mid 40's temperature wise.  To my suprise the skip was gone, but I ended up fouling a plug.  Not the center cylinder though....this time it was the clutch side again.  To this day I have yet to foul a plug in the PTO side.

Since the temperature was so warm, I can't say that the problem isn't fixed....it wouldn't be fair.  We are supposed to have snow for this weekend, and if the temps are half way decent I will be able to try it out.  I think that will determine the sleds fate.

I'm sure that you have heard 90% of this story before since you replied to most of my other posts regarding this situation.

Now that I read it back, it doesn't sound like all that many problems.  I guess that between dealing with my lack of knowledge + mechanics that don't know what they are doing + this weather, it kind of inflates all that has happend and makes me point the blame on the sled.  Maybe somebody could have taken care of these problems in one day if they knew what they were doing....I don't know....I haven't found anyone that does.  I'm longing to find a place that I can trust.  The same thing goes for the mechanics around here that works on cars.  It's hard to find anybody that knows what they are doing.  Some know certain things, and others know certain things....If they all worked together it would be fine, but they don't.  I can't afford to take my sled to 3 seperate shops and get 3 seperate bills just to fix one problem.  

Sorry about rambling on about the other stuff...I guess I just needed to vent again.  I am anxious (yet hesitant) to try my sled out again so I can see if it's all better now.  Like I said, the thing is great when I'm on it.  It's everything that I want in a sled.  Who knows, if I got something different I might have even more problems.  It's a gamble either way  


Thanks.

-Josh

I have a 98 Formula 111 700, i have 2200kms on it.  It is not stock by all means.  I'm running with Mach Z even on top end.  The snow just ended for me.  And a track let go on the river.  It has Crank shop pipes, used to have a picked track on it, E.G.T and some other stuff. have not lost to a 800 twin yet

z28 now are u im sorry to hear uve been having these problems.i have a machz 2000 and i dont ever remember fouling a plug. i run the breya`s i gap them everytime.. (i change them just cause i think that a fool season they must be tierd...LOL) but anyway. in the warm up is important for fouling. i dont let it iddle too long at start. mabe a minute. then i dont roll it i just keep giving it little blurps and i keep the rpm up. the next thing u might want to check it the oil injection setting. its right behind your exaughst can. it shoul line up with the line even back it off a little.next u should not have a br8. this is a hotter plug and the middle will burn hotter. so if your looking to change another piston id get that out of there.hope this helps
