Bonnieville t120 engine rebuild cost

hi all,

i am considering buying a t120 bonneville 650 with the engine out and disassembled. i plan to try and build the engine again myself but this being my first bike and my first bike build i dont have that much confidence in myself with regards to the engine. everything else i am more than happy with.

my question is... say i do decide that it is too much for me, how much would it cost at a rough guess to take then engine somewhere to be built?

apparently everything is with the engine and in good condition. or is there anybody known on these forums who rebuilds the t120 engines that lives in north west England and what sort of a cost would they be looking at?

any contacts or information of companies or places i could speak to would be great.
would also be great to speak to somebody who has had their 650 engine rebuilt who could advise where they went how much they paid and how happy they were etc?
cheers

 

that would be the perfect result if i could find somebody willing to show me.
thanks for the idea i will search that now and have a look!
