Yoyodyne carries a radiator kit, price about $1800. The problem I have with the kit is replacement parts. If I skip buying a new railer, I could get the kit. If my cheap experiment doesn't work, I may get a custom radiator made from C&R (they said about $350 to $450).
Yes Mrs. Tzracer is quite cool, but she prefers when I ride the TZ because then she has something to do at the track.
I am also going to get some of those side louvers. Anyone try them?
