I'll try to get the attachment now but I've never done it before, lets see what happens

Well apart from being upside down it worked. Number 85 is the rocket crank and the con rods have part numbers 67-1205 and 67-1206 which I believe are large journal

G'day All,
Thats the same crank that's in my engine,
it had all the spare parts guys baffled when I
needed the small bungs on a large journel crank,
none of them had heard of such a beast, so obviously
fairly few & far between. My '61 SR was an old hill climber
with quite a few performance parts, which I found when
stripping it down. I haven't ridden another A10 besides mine,
so can't compare, but can comment that mine is very smooth
all the way up to 80miles (haven't gone any faster than that).

regards, Cus

is the other crank shown (item 111) A7 or A10? from the parts list? it looks like a small jnl A10 crank.

I notice the parts list heading mentions A7 and A10 and the haynes manual image that looks like 85 has the reference A7. as presumably one image is A7 the other a10. All very interesting! Where would we be without forums!
