Hi there,
So, I got this '57 A10 that suffered over compression due to some nugget putting together what they thought were the best bits from two engines, even cut and Gas welded two Push Rods together to make one the right length!
Now, I am originally from just down the road from Small Heath myself, Redditch actually, the home of Royal Enfield. However, I now live in Uganda and as you can imagine, we are not exactly tripping over A10 parts here...
If anyone can make it easy for an old soldier to understand, I'd appreciate help in what ratio parts I need to get this old girl back on the road.
How do I tell, by just looking, which ratio Pistons I have? Got both short and long Cylinders, short one is a wright off, cracked and has a piece of barrel missing. I can't imagine it would be salvageable. Long Cylinder is good, sleeves badly scored though. Crank is true but will need grinding to the first oversize Shells (.25?). Con rods look fine, but I don't know if they were from the short or long block.
The bike was a rolling chassis with the engine in two big buckets when I got it. So I'm only guessing that the long Cylinder was on when it went pop.
So what do you think?
