The Star and Garter / Bent frame!
09 December, 2023, 19:25:37
I have an A65 which appears to be slightly twisted at the steering head. With the rear wheel vertical, the front wheel heels slightly to the right. The variance top to bottom is about 14mm at the rim.

Forks, swinging arm, and the main part of the frame check out okay with my crude assessment using spirit levels and string lines, but suspicion lies with the steering head, which does have evidence of having had a knock just below the steering head at some point in its life. There's just a small mark on the frame, but it's there.

At very low speed the bike feels as if it wants to turn right. At higher speed, riding hands off the bars, the rider has to shift his weight well over to the right in order to keep the bike going straight.

Obviously, I need to get the frame geometry checked and corrected.

Any recommendations as to where I could get this done? I've heard good reports of Maidstone Motoliner and Abba, but they are both in the south east. That's a long way from the Northumberland border where I live! There must surely be somewhere in the northeast where I can get my frame jigged and corrected, but I've drawn a blank so far.

I guess the alternative is to try to source a good replacement A65 frame. Anyone got one going spare?

Twins / Ignition Choices for A65 Hornet
04 July, 2022, 18:19:19
My recently acquired 1966 A65 Hornet has Electrex World STK 012D self-generating ignition and I've come to the conclusion that this ignition system is not fit for purpose.

The issue is starting. It takes many kicks to start it, during which time it will either do nothing, or will kick back with such ferocity that a broken ankle will soon be a reality. Either that or a smashed up kneecap from my knee hitting the handlebar when it violently kicks back.

However, once started, it runs fine and ticks over nicely. The ignition timing has been checked and is spot on, and the carbs seem to be fine too.

The issue appears to be that the Electrex World STK 012D will only produce a spark from 300rpm. Anything less results in a very weak spark or none at all. Kicking it over hard with the plugs removed shows nothing more than a very weak yellow spark. Is it even possible to kick a 10.5:1 Hornet engine over at 300rpm?

So, with no desire for serious personal injury, I'm looking to fit an alternative system that actually works.

I'm thinking about converting to a battery 12V system, either with a Lucas alternator or total loss, and using VAPE, Pazon or Boyer electronic ignition. The bike doesn't have lights but will be used on the road.

Any recommendations?
