Coffee Bean Engine Project

The Shortblock is already together
In this post we want to take a look inside .... 
Starting with an Industrie engine Typ 126 that has a slighty more than 3h run

                                                             Looks like new!

Crankshaft is a NOS German forged F-Typ
Dynamical balanced for sure!
Flywheel and Clutch too

The wrist pin of the AA Piston 87mm is too heavy

27g less than the AA, we take this one

An average weight Typ1 rod

556g in total and very good balanced, wit ARP bolts
Hmm let my remeber: 4x27g - wrist pin, 4x59g - rods, 8x22g -lifter
That`s 520g lighter than stock :-)

Here it is in the Case

The other goodies for the Coffee Bean:
Silverline Main and Double Thrust Cambearing
Clevite Rod Bearings
CB Ligtweight Lifters with 72g

As for all HP Engines
Thick washers and SW15 M8 nuts

The Pistons Need some honing because the wrist pin are too tight

Fabian`s idea for a Christmas present

A wine bottle holder, like it!

Super Stock Singleport

Not everyone is looking for the ultimate high-performance engine for its air-cooled vehicle.
Most of you  just want to ride with your well maintained Oldie with the regualar traffic. The problem is always when you need power for an uphill or to overtake a slow vehicle.

Than you may want to have a Super Stock Engine like this?

Looks completly like a Stock but ....... more powerful.

The reason to rebuild this engine was a loose Flywheel
This destroyed the crankshaft, the engine case
Broke all! Top piston rings

Broke two pistons...
Time for a new set of single port heads
This one are milled for an adequate compression Ratio
the intake is matchported to the EMPI SP Manifold
Longblock wit 87mm AA Piston and Cylinder a Camshaft for better torque and power.
Be careful with Singleport Heads and Camshafts, only a mild Duration will work with this! 
In-out pump and an additional oil sump will help to keep the engine temperatue in the right place on a hot summerday in a T1 :-)
