Great video, always an interesting watch. Love the A65 videos!! Question: The trick with the timing cover gasket is great 2:10 , I will do so too on my rebuild, what gasket compound do you use for this? Thanks!
@@teegee2556 I only use Wellseal where there is no gasket but understand the logic of Paul's method. I've seen it and done it myself but even grease can stick a gasket enough to tear it when case is removed.
Seems you have a bit of detective work to do on the origins and genesis of the motor. If the bike started life as a Spitfire MK IV, perhaps it suffered a catastrophic engine failure which necessitated a complete replacement. Might have been replaced with an earlier power plant. ??? I rate you as expert on these machines, and I'm sure you know their details by book and verse. But, I find the variations in stud sizes, crankshaft and oil pump design, roller/ball bearings vs bushes and probably a lot more which I'm unaware of...to be rather confusing. I'm currently considering a crashed (and then stored 50 years) 1963 single carb bike, but since it needs a lot of things replaced, the unknown factor in part specifications is putting me off it. Good fortune with your project!
What's the weight of those new rods compared to originals? I had my crank balanced, even though the replacement Thunder rods were very close to weight of originals
One piston? ,all that money spent on connecting rods and the owner is too tight to treat the motor to two matching pistons of the same type and age , have a word with the owner ,now is not the time to cut costs and risk damage to sound components.😟
If it only needs one piston, why buy two. Money will be spent where it is needed, the good piston is like new. If we go down that road we might as well throw the engine away, buy new everything and build a new engine from scratch. It has new conrods and big ends and new bearings and one new gear in the gearbox - all it has needed so far. Nothing to do with the ownner being tight, which he isn't, for the record.
Thanks Paul.
You'll whisper it! I see you have a constant supply of these underrated bikes/engines to fettle. Folk rightly have great faith in your capabilities.
G'day Paul, your spot on with the engine rebuild, the jobs coming along nicely, cheers mate, Neil 🤠.
Thanks 👍
Excellent, that's proper dedication finding the best meshing.
👍

Thanks. In this instance I used Wellseal, but other brands are available.
@@paulhenshaw4514 I see, I also use Wellseal, but on both sides until now. I will try the grease method. Thanks fot this great tip!

I honestly don't know. Conrod weights have never been an issue to me, even when changing from alloy to steel in the Royal Enfield Bullets I tune.
Off and on like a rosehip's draws 😂
