TL125S
Skoti:
Well done Dave,
carefully making sure everything is spotless and clinically clean is the only safe way to assemble those engines.
Did you have to renew that timing side main bearing?
Johnny4428:
That is big leaps ahead there Dave, some great work, good to see it coming together.

Timing side bearing was fine Skoti as was the crank. I renewed the gearbox bearings (three of them) because two of them were really noisy after a clean. I also renewed the clutch lifter bearing.
Yep I agree when assembling an engine you have to be really clean, it only takes one piece of grit getting into a plain bearing!
Thanks Johnny, there's light at the end of the tunnel 👍
Laverda Dave:
It’s been a while since I posted an update to the TL125s. I’ve been on holiday but had to travel back a week early due to a family bereavement and I’ve had little enthusiasm to do much recently as a result.
I spent 5 hours on Monday at Moorfields eye hospital having been sent there as an emergency by my GP after suffering a bad haemorrhage and severe clotting in my left eye (no idea how I did it, no trauma injury, my BP is spot on as well). I’ve been told not to lift, sneeze, carry heavy shopping or ride the bike for a couple of weeks whilst it heals (I assume they also meant no garage time either?).
There was a minor amount of work undertaken over a couple of days last week. I fitted the new piston, rings and newly bored barrel returned by Bryan. I ground in the valves and reassembled and fitted the head with a new cam sprocket, chain and tensioner blades. I did find though that the large oil seal that fits between the barrel and head would not fit properly, it was too big in diameter to fit into the recess and stopped the head mating with the head gasket properly. Someone has made a note in the parts books this seal may be too big and to use an O-ring (they actually put the part number in the book as well of the o-ring to use). Once I fitted this the head went on smoothly. I received a parcel from Ash with the elusive exhaust guard, headlight, wiring loom and a newly softened inlet rubber (thanks Ash). I have now assembled the engine as far as I can go and until I order the oil seal for the points cover.
I chased up the chrome plating today as it’s been 10 weeks since I sent it and without some of those items being returned I cannot assemble the rolling chassis. And mount the engine into the frame.
I have found a company quite local to me who have quoted me £125 to blast and cerakote the complete exhaust system which is a good price (for London) so hopefully I’ll take that in within the next couple of weeks. I also managed to buy a litre of Synstryp to remove the layers of paint form the fuel tank, I won’t even attempt that job until my eye heals (and I’m wearing suitable PPE because Synstryp is nasty stuff).
Bryanj:
Looking good Dave, hope you are better soon
