The Opy Hiro, Multi Purpose Racer has had it’s ups and down since the project  began late last year.  ECU problems, and constant overheating issues at the top of the list.  Unfortunately, Lars was unable to locate a simple source for the engine overheating issue that’s been plaguing the build since the beginning. So, after finally getting the electrical system up to par with the replacement of the ECU, the decision was made to remove the engine and have his long time machinist check the block and head for cracks, warping or other failure.

I spent the afternoon with Lars a couple weeks ago while he went through the process of removing the engine and drive-line from the stricken race vehicle.


Stay tuned!  We’ll have a new update with tehe engine replacement coming to you in just a couple days.
