Review on Wiseco PK1590 90 50 9 5 Compression by Rex Bareham

I purchased this item with a part number from the Wiesco website. I fitted and worked perfectly on my 2002 Honda Foreman 450es 4x4. Sent a pitcher to process at .020 and came back with a gap in the ring just below .003. I slightly chiselled the annular gap with a file. Installed and everything is great. Nice performance increase, works great and best of all: no more smoking! Good buy and again.
