Message: [QUOTE="Yroc, post: 1226407, member: 80182"] I replaced the oil in the cartridge with yamaha S1 oil and put ATF in the outer chamber. After riding 20-30 miles, the forks became much harsher and stiffer. When I got home I pulled the cartridge off and ran it through it's full stroke and red oil bled out of the over-flow holes. The S1 oil is originally clear and I don't see how the ATF oil got sucked inside there?? What do I need to look for and what can make this happen?? I can only think that it was somehow sucked into the overflow holes to the inside, or the seal at the bottom of the cartridge that seals against the rod, but that seems unlikely that the seal would go bad in both forks at the same time. Is there any possibility this is a bleeding error?? I don't really think that it is as I know how to bleed these cartridges now, but any help or possible solutions would be greatly appreciated. Thanks in advance. [/QUOTE]
