There are heaps of posts on IMS vs Clarke gas tanks for the 07-09 WR450 but not much on the Acerbis 3.3. http://www.justgastanks.com/store/index.php?main_page=product_info&cPath=1_70_182&products_id=347 Anyone got one? How does it fit with rad guards? Quality? Petcock issues? I need a larger tank pronto for the V2R coming up in a month. Thanks.
