My new project. IMS Oversized tank, FMF GYRT Titanium slip-on, Work Connection REM MX skid plate, O-ring Chain, 14T ctr sprocket, stock springs and valving with sag @ 110mm. Next steps: Work Connection Longer Link, Dr D Eng and Rad relocation kits, BRP sub-mount with Scotts damper. Replace the leaky IMS oversized tank. Yeah, I'm like the third guy in my group with an IMS tank issue on this model bike. Leaky around fuel pump...2015 YZ-inger.png That's interesting about the leaking fuel pump. I have not had any issues with my IMS tank. I reused the original seal and didn't use any sealant. Hopefully IMS is working with you to resolve the problem.
