I have a MAHA dyno with ramps ( you can use it in or on ground as you wish) and esp Evap machine with smoke tester attached to the unite for sale.
Maha dyno just serviced and belt replaced by OPUS today ( have the receipt). passes the calibration. Evap unite also passing calibration.
bought them about 5-6 years ago in hope to open a second shop but it never happened.
Make me an offer and it is yours. Not in a rush to sell them so make a reasonable offer ;)
