Now things went pretty quickly from there on. Getting a bike with such simple controls (just a brake cable and throttle running to the rear!) together was just a few day's work.The next big one was to get a suitable exhaust. First attempt: try on of Lambretta Innovations' pipes as shown here (on a buddy's bike who's done the same conversion).
As you can see, we didn't have a real fixture and the pipe bulges out way too far to the right.
It runs like hell though - based on the 360 degree PM pipe for Gileras.
Second attempt: Jim Lomas of JL exhausts live somewhere in the sticks in the Czech Republic, just a few hours' drive from Munich.
Here's what he got done after a year's work...


And here's the almost untuned dyno run (upgraded the rollers to 9g):

Pretty good, 17 HP on the rear wheel for most of the time. A standard TS1 doesn't keep up!
