Thanks for all the info everybody. I learned the hard way with a '94 Wildcat I have how important warm-up time is. Now, when I start my sleds I let them warm up while I put my ridding clothes on, usually by then the tops of the heads are starting to get pretty warm. Even then I try not to get on...

Thanks for the help, Wiseco it is.:beerchug:

Are you talkin' about having the ring ends gapped properly when fitted into the cylinder? Not quite sure what you meant by "fit and clipped"

Which pistons would you guys use, SPI or Wiseco? It's time to do a rebuild on my '96 Thundercat and I wanted to know what would be the best for a stock engine. Thanks, have a good one.:beer:

Do any of you guys use SPI pistons. It's time to do a rebuild on my 900 Thundercat and I want to get the most reliable pistons and rings for a stock engine. I'm torn between saving a little money on SPI's or spending a lot more on Wiseco's, but when it comes right down to it I want a good strong...

Finally heard back from Cat on the samples I sent them and the manufacturer says the oil is ok it's just a little short on the green dye they use to make the oil darker.

Hey everybody, I just talked to a guy from Arctic Cat named Tom Schaefer, he is the oil coordinator there. He faxed over to the oil manufacturer the picture I had sent him about the differences in the oil. Unfortunately, when he faxed them the color pictures I sent him they got it in black and...

No I it's clearly stated on the containers which ones are APV and which are 50:1 INJECTION OIL. The ones I have say 2-CYCLE 50:1 INJECTION OIL. I read them a few times just to make sure I didn't miss anything. Check Out my next post FALLEN, I actually got a reponse from CAT.

Alright here we go, this is going to be a little harder to explain than I thought but here it goes. In pic#1 I have it arranged in pieces so you can see what I used. The gold colored washers need to fit around the outside of the water pump shaft, you will need several of them. The sleeve is just...

Let me get some pics together and I'll get them to you as soon as I can.

Has anyone out there noticed this difference in Cat's 2-cycle oil? The one on the left is oil that I just purchased this past weekend and the one on the right is oil that was bought back in the fall prior to the season. The one on the right is what I've always known Cat's oil to look like. Is...

I don't know what they are for the ZR, but a Wildcat 700 in the same year they recommend 8100-8300 peak.

It came with a 49 degree, I changed it to a stock 57/50, the only other thing I had to do was change the hole the spring was located in. Originally it was in the middle hole but that upshifted too fast and I lost top end so I moved it one position to the left and it works great know. Sorry for...

Make sure you mark everything before taking it apart to get all the parts back in their original position. Moving the spring into the holes going to the right will put more tension on the spring which causes it to upshift faster and you will lose top end but you have to careful about over-reving...

I've got a '96 Thundercat 900 tripple, virtually the same engine as the 800 zrt, and I love these big trips. One of the most common problems with them though is the water pumps seals. If you notice antifreeze leaking look up at the bottom of the water pump and see if it's comming from the small...
