Re: 600 xcr rebuild
I just got done doing open heart surgery on Frankenstein. I had a really good machine shop bore it 20 over and re-chamfer the ports,
added an oversize set of Wiseco pistons and rings and we were running in three days. Make sure that no junk got into you crank
case. I did the work myself and it was a piece of cake. You'll need a friend or a patient wife to help hold the cylinder block while you
insert the pistons into the bores. Total cost was $330.00.
However, I have rebuilt dozens of chainsaws and single cylinder motorcycle engines, so I was'nt too afraid of my first multicylinder
You have to watch the early 600's like yours. They don't get enough oil at times on the PTO side crank bearings. My brother had the
local Polaris shop add another oil line and now it works better than ever. (He ate two cranks.) I believe it was a Polaris official
modification so your dealer may know something. Good luck.
Oh yeah, the first rule of rebuilds is find out the cause of your problems first. Like a leaking carb flange, base gasket, or jetting.
If you can't buy what you want, BUILD IT!!
