Damn factory piston!

I had the piston skirt break off on my 97 scrambler 400. Figuring it’s age I thought it was going to happen and it did. Luckily no damage and I can redo the top end with the motor in the frame. Haven’t found any pieces so it makes me feel like it was slowing breaking up and getting spit out the exhaust. Quick hone and a wiseco piston with new rings and gasket it should be running better then when I got it. Happened in the first trip out as well, good thing is it got back to the truck and loaded under its own power was just backfiring bad

Rim Size, 14 VS 12?

Figured before I buy Rims I'd ask on here.

My stock size Rims and Tires on a 2007 700 EFI Twin are:

Front: 26-8-12

Rear: 26-11-12


What is the advantage of going to 14 inch Rims vs staying with the 12 inch?

I do NOT plan on doing a clutch kit or lifting the bike. Would going up in size from 26 to 27 or 28 give any advantage or problems?


Thanks for your insight.

250 2 stroke meets 425 magnum

So I picked up a 91 trailblazer 250 that likes to run for about 15.minutesnthen stall. Got her for 70 bucks and in a mess. 425 I picked up free and at 1 point was all there then the locals had their pick at it while I was visiting my brother so now just the frame motor and suspension. I am thinking since the 425 is slow maybe swapping the 250 motor so I can have 4 wheel drive and a bit more snap. Can it be done.

service manual for 2005 polaris atp 500

Hello everyone, new to the forum and have I a question...

I´m about to restore a 2005 Polaris 500 ATP from my grandpa. Model No A05JD50AA
The problem is the ATP, is in a complete disassembled state so I looking for the service manual.

So far I can only find the service manual for the model no: A05MH42AH A05MH50AH A05MH59AK A05MH68AK and A05CH50FB but not for the A05JD50AA
Or can I use those service manuals for the A05JD50AA

I´m looking specifically for the wiring diagram and the carburetor assembly.
If someone could point me to a service manual for the 05 500 ATP it would be much appreciated.

Sorry for any spelling mistakes. I‘m from Germany

Thanks in advance...
