I bought a Dynojet 250ix Dyno in August of 2013. I'm closing my shop and looking to sell it. It has every add-on possible. All the above ground panels, computer stand, actuating electronic front wheel chalk, wide band tuning tools, built in AFR monitoring and Ramps. I've tuned less then 100 motorcycles, 4 trikes, 1 four wheeler. The drum knurles are still in great condition. I'll throw in the computer that I run with the Dyno as well. Dyno was just serviced in April and the stack was refurbished in May.
