Looking at selling my engine over the next couple of months to make way for a different motor. Just a heads up really for people who might be interested, the sale however, is not definite.

Specifications:

Bottom End:

A12 74.5 Bore
Full floating flat-top pistons with fly-cuts
Balanced bottom end from front pulley to clutch pressure plate
Wade 224A Camshaft
Lightened and knife edged crankshaft
Lightweight pushrods
Lightweight & perforated flywheel
Brass button clutch

Top end:

Aluminium Valve retainers
Double Valve Springs, fresh
Ported and planed H75 head with lots of potential
bprojects inlet manifold with twin japanese Mikuni carbs

Ignition:

Big bosch dizzie with bosch coil,no vacuum advance
10mm ignition leads, nice and fat to carry a decent spark

Additional info:

Engine was freshly rebuilt weeks ago, I spun a big end bearing due to being a little impatient with the oil-pressure priming (either that or I wasn't patient enough on the break-in) but anyway I have fitted a stock crank and it's all running good, this time I'm breaking it in slowly. I am working to get the knife edged crank back into the engine. It's a good motor that I have enjoyed having, I am looking to go for a bigger engine with a little more torque at lower rpms. This one was fine but it's lightened internals coupled with a 224 cam and a brass button clutch meant it's a temperamental engine that only likes to be driven hard, basically no good for a daily but good fun for an occasional drive. The motor is tuned but could certainly do with some finer tweaking. I'll need to confirm the comp ratio again but it was around 8.5 last time I checked, obviously room for more compression and more power.

The engine goes hard and screams like a banshee, it could really do with an air-box to quieten down the carbs and could also do with a tamer camshaft. The induction roar is very aggressive and pretty damn loud, sounds sweet though.

Price: Looking for offers over $2000.00 and I am somewhat interested in swaps or swaps + cash.

Contact: email preferred or PM

Here is the most recent picture of the engine:

Here is a video of it before the rebuild, it had chronic blow-by but still went well.
