  1. My 1999 Mach 1

    When we brought her home...(2013) Her first time up north...(2014)? Second trip up north...(2023) Last trip it started running like dog crap on the 3rd day, along with only revving up to 7000 sometimes 7500ish the whole time. Carbs were gone through before we went on trip. Got home, turns...

    I have a 99’ f3 700 tore apart , just reassembling and I need someone who can 100% tell me which way the oil seal sits in the mag housing ?? Didn’t play close attention when pulling out and can’t recall which way the spring in the seal is facing. What would make sense to me is the spring facing...

    Hey doo lovers, Picked up a new to me '99 MXZ 670 HO over the summer that was in really good shape (eyeball test), but didn't run for last couple years according to owner. At the time of purchase it had good compression & spark. Took it home, drained all old fluids and put new crank seals in...
  4. 1999 Sk-Doo MXZ

    Things been with me since I was a kid around my neighbourhood, all owners knew each other so it passed through them with no worries. Practically stock beside a purple belly pan. 8000km, pretty low for 3 owners, literally zero rust or any problems with it, definitely needs a tune up though...

    Hey everyone! I am trying to fix my 1999 skidoo summit 600 and am not too sure how to go about this issue. Here's the situation: My sled fires up no problem but when giving it gas, it doesnt engage/move. I did a bit of digging and I am pretty sure its either a DESS post or MPEM module issue...

    Hello All, and I hate to be the Newbie who asks the question that's been answered 100 times, but damned if I can find it here on the forum. Did searches with different wordings and only came up with one (short) discussion that advised checking a fuse. Purchased a 1999 Grand Touring SE 800...

    As far as I know my sled is a 99 I've had people who specialize in skidoo tell me it's a 99 but seems there's alot of people who get bent out of shape over me saying it's a 99. Help please did the 99s exist or didn't they I'm annoyed at this argument haha from what I've been told they were made...

    Where can I find a main exhaust for my sled that won't cost an arm an a leg.

    The sled is a 1999 ski doo 600 mxz it was overheated maybe 5 years ago and i rebuilt it with a top end kit with new pistons and rings. The sled has also used a bit of coolant more since it over heated but its not like i keep having to add but once it gets down to a point it just stays there and...

    Hi Everyone, Im currently working on my nephews sled. He has a 1999 Formula Z 500 L/C. The sled has electric start but its not working. I put a brand new crank battery in her and checked the 30 amp fuse(looks good). He broke the key off with his foot but half the key is still in there. Enough...

    Hi everyone a few weeks ago i started a topic asking about the reliability of the 670 HO. Well i bought it for 1100. and the compression is great. All it needs is the shocks rebuilt and a new rear spring. anyways heres some pictures of it all cleaned up...

    Hey guys, My 1999 mxz 600 is really bad on gas after a full engine teardown and rebuild. The pipe was also replaced (lots of holes), and the carbs have been gone through and cleaned. This damn thing used a half a tank in only 20 miles.
  13. MXZ / Legend / Summit / Grand Touring / Formula
    Got a 99 f3 800 that was leaking coolant into the 3rd cylinder (pull cord side) I replaced the head gasket and seals. The plug was no longer getting wet with the green coolant upon visible inspection. Now I'm loosing coolant somewhere while it sits for days and can't find it. I have no puddles...

    I have what I believe is a 1999 mxz 500. I've done some research and am 99.9% sure it is a 494 l/c engine with the rave exhaust. I don't see any 1999 mxz 500s on Craigslist or read about them on hear and am just wondering why that is? It's always been a solid engine with only 2000 mi.

    Hey guys, i have a 1999 mxz 600 with a rusted exhaust pipe. the local parts shop has one that just says 2000 mxz, it doesnt specify the size motor it came off of. would a 2000 pipe fit my 1999, and would it have to be from another 600. Thanks.

    I pulled the carbs off my 1999 Formula Dlx 500 Fan today (Mikuni VM-34) in the process of stripping them down and pulling the pin that holds the float arm, the tab broke off the bottom of the actual carb, The other one was just as seized so it is staying, yeah, not a good day... Needless to say...

    Hey all. First post here and hoping for some assistance. Purchased this sled early this year. Haven't had it out yet, but am planning heading up to MI this week. Doing a little work on it this weekend and I noticed coolant at the front of the motor. After doing some research, I'm a little...

    I think I found my spark problem with my mxz. A piece of the recoil broke amd fell into the stator. It obviously got hot and cracked the insulation on the stator and melted some wires. I need a stator and possibly a pickup coil. I'm paypal ready.

    I picked up this one last week locally off of CL, 99 F3 700. Kid said it was running and just quit. He wanted to part it out but I made him an offer and he took it. Isn't beat up too bad. 5xxx miles, newer track with less than 500 miles on it, updated skis, shocks and no major cracks or dents...
