Snagged a ever so slightly used Corbin for my '02 650L. Already have a Clarke tank (I think the 4.0 one) on the bike. Went out to install the Corbin this morning and simply cannot get the seat forward enough on the frame to line up the two seat bolts. Ok, so I "could" if I used a big enough hammer, but I'd rather not damage the seat... Anyone know if the Corbin will/won't work with a Clark tank? Calling Corbin they say that they "understand" it works with an IMS, but no clue on Clarke. Anyone? Anyone? Thanks!
