I liked the Tubliss so much on my Husky that I'm putting an MT43 with Tubliss on my Gas Gas but I ran in to a minor snag. The 2.15 X 18 DID rim on my Gasser has a deep narrow center channel where the spokes are and the plastic boss on the rim lock doesn't fit flush. I'm assuming I will have to reshape the plastic boss to fit. Has anyone else had this problem? I e-mailed Jeff at Neutech but have not got a reply yet.
