Featured T120v 1972

Hi all
Newby here
I have an absolutely original never been painted mint 1972 T120v
Genuine 1600 miles
There is still the original gold made in England sticker on the frame
Been stood in a carpeted room for at least the 20 years I've known my daughter's father in law with the carbs and tank drained before storage.
Cleaned the tank as there was the slightest of dusting inside
Changed all the oils Castrol in both gear and engine fitted new battery took some finding for the right size,fuel pipes and give a clean with warm soapy water
Fired up almost immediately
Ran lumpy first few mins then after a short 10 mile run it's as sweet as a nut. Front brake took a bit of bedding in but good as new now
2 questions
Does it need additive in the shell optimax and the million dollar one
What's it worth

 

Morning everyone
Thank you for all your replies
I have been busy last couple of weeks so apologies for the late response
I was out on the bike Friday afternoon and it really is like new
Even with the tyres being a tad hard it rides well has plenty low down torque and is surprisingly comfortable.

It had been stored in a carpeted man cave for last 25 years with no ultra violet light so the tyres aren't as bad as they could have been but will need changing.
Met my brother who was out on his 890 KTM, what a contrast
