has anyone ever heard of boring out a polaris 400l to fit a suzuki piston or other brand for that matter I have a 86.92mm piston in a 400L this has really been a challenge to find a replacement I have a broken ring and it left a small dent in the piston by the ring is there any chance I could just get new rings and not a whole piston please let me know

 

Hey man they make all kinds of over sized pistons for the 400
wiseco

check ebay

check www.rittercycle.com
check www.hpd-inc.com

they make massive overbore, it should NOT be hard at all to find a piston, they make TONS

 

what dose it mean when it says .160 or .180 over what size piston is that if std is 83.00mm

 

if i go with a custom forged from hpd .160 over that should be a 87.00 will this work will i need a small bore to get it right if my current piston says 86.92mm

 

Call me - 618-644-3211 .
86.92 is piston diameter - not bore diameter .

It will set you back $190 or so delivered - remember too - it takes a special head gasket - $30 .

 

Rings only available too - $38.00 delivered.

 

thank you so much rick I have been down for like two months and only had the wheeler for like a month before but I rode it every day it would be awsome to get it back on the road I will give you a call
