    Is a vhm head better than a ported stock head

      Heads are not ported on two strokes, but some OEM heads can be cut. We cut and machine oem heads for many of our race combnos and also have our own special head inserts and shells we sell for others. VHM is just one of many brands who sell race parts

    Hey bro got a stock head and vhm head for a 02 rm85 I have people are telling me to stay away from the vhm but why? I did blow the head gasket but I have to many anomalies and other things to question to blame just the vhm head but doing a top end and wondered if you’d run the oem which we put 4 hours on no issues but first ride with the vhm she died but was a massive change in temp from 15s to -3 so I reckon that’s where we went wrong lol but also swapping coolants

      @@HPRaceDevelopment issues are with the vhm insert check my latest video the insert is 50% cracked half way around lol quite a bad crack could have been me over tightening it or the fact she was low on coolant and we took it out at -3 so but yea turns out the insert was ruined all along not the piston or gaskets lol top end for nothing but it’s peace of mind and it’s about the right kinda time now anyway

    Could you look and see if the Yamaha wr200 cylinder will fit a 2006 125 bottom end like ktm. A 2006 yz200 is way more rare than a 2003 kx200. Its running pretty good for a stocker ua-cam.com/video/d93hQ8YO4Zc/v-deo.htmlsi=m78S8_DEaqwpGYHa
