Im now the proud owner of a 68 T120R
Most of the boring work done Just rebuild engine and wire etc
My question is crank balancing and matching weighing everything . I just paid guy and asked about crank he’s had it ground 10 thou but no balancing etc.
I get bike Friday but probably won’t be in England for a while to check it out.
I have a pre unit smooth as silk
And sold my oif bobber as rattled my bones out .

thats a good buy fella,... as a spotty faced kid in the 70's I was weekly offered any amount of pre unit Tiumphs & the most expensive was about £120,... wish I knew what I know now back then & I would have been at Lloyds or Barclays begging for an overdraft !!!... bloody scary what they go for now !!!

Nice looking machine! Frankly, I think people get too wrapped around the axles over crank balance. The manufacturers weren't all that critical about it. Just clean the sludge trap and put it back together. You want smooth running, nothing beats lowering compression ratio....sure, you'll lose a bit of top end power, but make up for it in mid range torque. My two cents. 😉

Im making up a list of parts
The threads on exhaust camshaft are mangled And I’ve been doing some research seems in 69 (before this no)they were nitrided I presume if I replace with new nitride would be standard finish?

So arrived in England (heatwave and hosepipe ban )
Keeping away from mum with covid. She has had it 5 days, but dad is fine ? (76 and 81 )
looking at what I need,got the 68 parts book on my telephone and looking at what I have laid on the bench, it’s an epic (took like 6 hours with beer )
But finally think I can buy what I need tomorrow and button this fucker up,
Got the cam allready.
