IMS 4.7 gal and Unabiker rad guard

Gents, I expect to be acquiring a new WRR shortly and wonder if any of you has fit the IMS 4.7 gal tank with a a Unabiker rad guard. I understand from a lot of web searching that clearance is pretty tight under some of the IMS tanks.

If no one has experience with the Unabiker guards how bout another brand?

Thanks.

I don't think a radiator guard is needed, really, with the IMS 4.7. It replaces the shrouds and is pretty stout, basically doubles as a radiator guard for side impacts.
