The UCE is a better choice for you.The AVL was made in 350 and 500, so it could be either one. Only the 500 was exported to the US. Not many AVL bikes were sold in the US. It was an interim engine between the vintage Iron Barrel Bullet and the UCE.The strong point of the AVL is the shaft style rockers. The weak point is the non-adjustable TCI ignition timing.There are some internal similarities with the AVL and UCE
Anyway, what could you tell me about a 2006 Electra? Were there any in 500 CC, or are they all 350's?
Guess again, that **is** the 500 Electra-X, sometimes the little round "X" sticker below the Electra decal wasn't always added, but that does not mean it isn't the "X" Like I said, the 350 Electra has the old-style engine with the cast iron cylinder barrel.
If this is the one that really does it for you, fine - despite what I advised you I do love the AVL engine, I ride a modified Electra-X and a custom RE based on an Electra-X hybrid engine in a 1960 English Royal Enfield frame. With a bit of tuning work they can go really well. Yes, there are some known weak spots, primarily the sprag clutch on the Electric starter, the cam followers whose stems can snap and occasional crankpins where the hardening flakes off. But that doesn't happen to every Electra-X, so if the seller ever does drop the price, you need to make your best judgment about whether this is a suitable machine for you. You can of course risk it and set aside money for repairs when something breaks.
ABC:As you've already decided against getting the AVL I guess this is academic but here's what my memory is saying about the AVL.
The oil pump was redesigned to get rid of the low pressure piston pump. It was replaced by a gear pump. Unfortunately, they kept the worm drive design used by the IB. Worm drives are easily overloaded and the gear teeth on drive pinion and the cross-shaft worm teeth will be damaged when this happens.
The old points and condenser were eliminated and replaced with a more modern pickup coil to trigger the ignition.
If I had the choice of spending a little less money for the AVL vs spending more I would hold out for the UCE.It's proving to be a very reliable engine.
It's great to find a community like this one dedicated to sharing about these bikes.
