i have a 93 Polaris 350 and need to rebuild the topend, there is no machine shop within 150miles of my home, does anyone know a reliable shop where i can send it to get it bored? any suggestions on the best lace and best kind of piston to get? any help would be appreciated.

 

ALOT OF YOUR LOCAL AUTO PARTS HOUSES HAVE A MACHINE SHOP. IF YOU HAVE TO REPLACE YOUR PISTON GO WITH A WISECO PISTON. NOT THE STOCK. I DONT KNOW WHERE YOU LIVE SO I CANT HELP WITH EXACT PLACE TO TAKE IT.

 

You can take it to a local NAPA autoparts shop, or send it off to doug nicholas at nicholas cycle to get it done.......his number is on his stie(www.nicholascycle.com)........Also go with a wiseco like he said.....much more reliable

 

Well, I"m having the same problem, and the polaris dealer quote me $780 for rebuilding the top end. What do you think about this price, and is it worth putting a thousand bucks in this bike? It's high milage, worn a lot, but mostly has run well. Any opinions? Also how much would a wiseco piston add to the cost?
Thanks!

I have seen Wiseco piston kits go for as low as $69.00 to $105.00

 

$780 to rebuild a 2stroke is ridiculous. $780 should get you a BRAND NEW cylinder and a wiseco and a couple hundred dollars leftover [img]i/expressions/face-icon-small-wink.gif[/img]

You could send it out to RCR (www.rittercycle.com), its around 35 to bore/hone out the cylinder and 100 for a wiseco piston. So for $150 including shipping, the top end will be ready to go.
Add in another 15 or so if you need a new upper needle bearing, and 15-30 for a gasket set.
It is very easy to disassemble and reassemble yourself, just make sure to lube everything up well with 2stroke oil.
