My friend has a Puch and I can beat him on the takeoff easy, but he catches up and passes me by while I am doing 24 he will be going 30-35.
The only info I can find is in German.the Mop-Shop
They have a lot of performance parts for the Solo 713. They look the same as the Odyssey so I wonder if they are compatable. Just Google Solo 713 tuning and you can see the list of bad ass parts for the Solo peds.
I guess I am going to try for a 15mm carb. I will probably have to cast my own intake for it.
