Greetings lads. I've recently completed a raffle blke for a small rally I helped put together here, state side. The rally was held on a friend's farm and the bike was built to handle some serious off road shenanigans. Otherwise the breif required that it be cheap to put together, ridiculous, and preform as addvertised.
This is what was started with
It was an early 60's Allstate that should have been left alone, but the price was right.
The engine is nothing special.
This is after it had been sand blasted. It was living for some time under water and as such, only half the case proved serviceable. The clutch side, while not pretty, worked just fine. Beside being under water the flywheel side crank bearing had been pressed through the case. The damage had been welded up but we can do better.

To feed the lights I used a stator and flywheel off an LML.
A long stroke, cut, P200 crank with the clutch side lip turned down was used with a 62mm Suzuki piston. This I fettled to mimic the original Malossi piston. The n.o.s. Suzuki piston is a good $50 cheaper than the original so I think it's worth the bother.
Clutch side seal and bearing. I put a smear of Loctite bearing retainer on the seal and bearing to keep them in place as their positions are reversed in these cases to accommodate the P series crank.
A combination of long stroke, long rod, short Mallossi cylinder, faced cases and a piston with a non stock compression height gives about a -7mm deck height.

Keeping on.
The center tank used to live on a '78 Yamaha GT80.
A healthy coating of pickup truck bed liner was applied to the under side and what-not. While what's left of the original paint was given a coat of clear to preserve the "patina"
I wasn't happy with how the Malossi head would sit on the cylinder, so I got creative. I used 4 of the hollow Vespa carb bolts that I tapped clear through with a 7mm tap. The stud holes in the head were drilled out to accommodate the bolts and hey, presto! Now the head stays put with the bonus of it being neigh on impossible to strip out these head bolts.
