1999 ski-doo mx z 670 h.o Toni Haikonen edition

I made the move this summer and decided to get another SkiDoo.
I picked up a 1999 SKI-DOO MX Z 670 H.O Toni Haikonen 06.
It is all stock with studded track and only has 2,400 miles on it.
It seems to run great.
I still need to get rid of my 1997 Polaris XLT, but looking forward to the new Skidoo.
I do not know much about the 670 H.O Toni Haikonen edition, but I am guessing it will hold it's value.
Also hoping it is easy to start and fast.
Anyone have any advice on this sled?
Leave it stock (because it is fast enough) or put a pipe, jet kit & clutch on it?

670's are bulletproof.

I just started it again tonight.
It sure starts easy...that is a huge plus.
It does not want to idle at all though.

It sat for 2 years, so the gas is a bit old.
I put some SeaFoam in it and ran it a bit.

Hopefully I do not need to pull off the carbs and clean them.
It looks a bit more complicated on this sled compared to my past sleds.

I think I am going to ride it stock this winter...hopefully it is fast enough.

You need to drain the old gas out and clean the carbs. You should be cleaning the carbs every preseason.

There is a tutorial on carb cleaning in the how-to's section of this forum.

I think you will be very surprised by that engine. That was the first doo to use the DPM set up. It has 44mm carbs stock.

If not that one then it must have been the summit x 670. Same engine.

99 mxz 670

The seafoam worked. It runs and idles perfectly now.
But I know I probably should pull off the carbs and really clean them before winter.
I am going to buy a louder exhaust can for it (and a new windshield). I the aftermarket can will not really give it more power. But I like the sound of a louder can. So to me it is just like someone putting on a decal or aftermarket seat.

Anyone know of a place to find a used slip on can for this sled?
Or a good windshield?

Louder is not necessarily a good thing to do.
Check your state laws regarding exhaust modification.

Be patient and you'll fine a set of used pipes for about a 100 and gain a lil power and sound.

loud pipes on my MXZ

I do understand that putting a loud pipe on most things just makes more nose and little performance is added.

My 70 chevelle has headers and glass packs.
My motorcycles always have race pipes.

I just love the sound of a motor. It is a personal preference of mine.

However, I do understand that loud motors can be extremely annoying to others.
I never fire up my car early or late (mainly because I will wake my own kids as well as the neighborhood).

So I was thinking I may build a cut out pipe for my MXZ.
It can’t be hard to weld in a cut out that goes into a straight pipe, bypassing the muffler when I choose.
This way I can run through the muffler at night or on the trails that go through the neighborhood.
And still open it up when I am fooling around on the lake.

I am thinking that the expansion tube does all the real work of keeping back pressure and the muffler just quiets it down…right?
So a cut out into a straight pipe won’t hurt performance, just add loud sound when I want.
Anyone have any experience or technical advice on this one?

track question

The track on my 99 MXZ is OK. It has a little dry rot on it.
Someone local is selling a perfect condition track off a 98 MXZ.

The numbers on his track state: 504152080

But my track has a 570-2126 model number.

Does anyone know if they are the same size?

I looked everywhere and still can't find if they are the same size.

replacement windshield

I just purchased a Cobra 12 in. Low Black/Yellow Windshield from Dennis Kirk.

The original that was on the sled was all scratched.
THe original had a headlight trim on the lower portion.

THe new one is a longer windshield that covers the headlight area and states:

•Requires removal of black plastic headlight trim

Problem is that without the headlight trim, it leaves a gap.
I put the headlight trim back on and covered it with the new windshield and it seems to fit better?
Does that sound right?
Has one had this issue and a good solution?

MXZ flooding

Cleaned the carbs this past weekend.
But, I flooded it bad....and striped the pull start.

Do I need to drain the crank case like I did in my old Polaris?
I reached around near the bottom front of the crank, but did not feel any bolts that seemed like drain plugs?
