Supercharged Egli project
|When growing up in the seventies, with a healthy interest for internal combustion
engine powered vehicles, on two and four wheels, you were compelled to buy magazines
and books. Subscribtions were made and each month, titles like Hot Rod, Car Craft(US)
Motorrad, Rallye-Racing and Hobby (DE), were studied cover to cover. And then there
were the annual "Yearbooks", "Revue" or "Katalogs" showing the biggest,baddest and
fastest of each year. When it came to motorcycles on frontpages, you soon got the
impression of the superiority of the Swiss made Egli.
A structural strong frame along with massive conical roller bearings for swingarm
and headstock, iconic magnesium wheels as well as front fork and huge (in seventies)
280mm cast iron Brembo discs with Lockheed calipers.
|This rolling chassis was ordered for a 550cc Honda four which makes this bike even
more a lightweight.
|All parts rejuvenated - assembly remains|
|Initial setup will include a single Mikuni TM carb with acc- pump.|
|550 engine tested out okay in donor- bike.|
|Ignition pick-up setup. Fits under stock cover.|
|Special crank fitting with belt pulley.|
|Initial layout of the supercharger drive - tensioner will be added.|
|Main sensors for the engine management system will be oxygen, MAP and RPM sensors.|
|Because of the cantilever rear suspension battery must be relocated to seat hump.|
|Doing the wiring including the original lighting system, the Ignitech engine
management system and Vape Power-Dynamo.
|Change of plan - since the normal placement of carb behind supercharger interfered
with the monoshock setup, I replaced the Hanomag Roots blower with an Eaton unit. The Eaton
has a rear inlet, and by shortening the blower setup completely the big Mikuni TM40 just
fitted in nicely.
