Well done Peter...it's good to see the bikes that some said would never last being rebuilt with some care and attention.The picture reminds me of the box of bits that a friend dumped on me when I said that rebuilding a 750 is easy...it is,but the fee for doing the job was two crates of beer, thinking that I would get two crates of 24 tinnies each. Instead I got two crates of four bottles...of Heineken...about

If you go to the US site and look up dynoman he sells overbore piston kits for the F2 plus valves and guides(along with a different stem diameter set) to fit at less than Honda prices. Cam, followers and bearings, unless badly scored, I would use again.

Rebuilding is relatively easy, but more than 8 cans of gassified rubbish worth!! BIG importance is cleanliness of all mating surfaces, super clean oil passages and NO gasket goo in the oil passage areas

Hey Peter, where did you get the fork tubes from ? They are OOS from DS and CMS.
I was lucky my F2 was bought as a project to stop me getting bored when we shifted to working 4 on 4 off, it had sat out in a back garden with no plugs in for a couple of years. So I stripped and rebuild it, new pistons, rings, valves etc, but never got the chance to install and run it as I went overseas for work. So most of the new bits are already in there. I've just stripped the top end again to check it out, and already found a couple of things that I got wrong all that time ago

Cheers

Hi Peter, yes I am restoring an F2, luckily when I was collecting parts for the F1 I also picked up a lot of F2 parts as well ready for this one. There's no hurry on this one but it will not be to the same standard as the F1 as I am not 100% sure about the motor, if necessary I will swop it for an F1 motor, which will simplifify the spare part situation at least. I did pick up a complete spare F2 top end as "insurance" as well.

Cheers

What you need is a "Contact" in the US that Buzz can send them too so that they can be re-directed as "Second Hand Part" with a value of $20 so no import duty, tax or courier fee.

Should any HMRC people be reading i would never advocate stopping the money hitting Mr Browns pocket instead of staying in mine HONEST!!!

Well I am progressing the F2 restoration at a reasonable speed, the frame, swing arm, battery box top yolk , side stand center stand , engine brackets, and rear brake arm have just been picked up from the powder coaters, the finish at first glance is very good , but on closer examination I have noticed some  rough spots, which happen to be right there on show on the RH main front down tubes, it looks like they have coated over a  patch of grit, I suppose it is my fault in a way because this place does mainly commercial gates and railings, they do not seem to take a pride in the finish of pride and joy things like my frame it is all treated in the same way.Oh yes and they also lost my rear brake light switch bracket , F--- knows where i will find another one of them.
To be honest I could repair the rough areas using my 2k spray, and then all would be good, but I will probably leave it and just get on with the rebuild as its not as if I will be entering shows, all I hope to achieve is a good looking usable classic bike which will retain some of its patina.
Anyway having these parts back means I can assemble the bike as a rolling chassis, which  always gets the enthusiasm going, its a shame that its so bloody cold at the moment because that really puts me off getting cold hands and feet.

I remember it well, picking up all of the F1 powder coated parts, exciting stuff.

I rebuilt the 750 up in the bedroom and it sat at the end of the bed while I put the engine back into the frame etc. Mind you I had an understanding girlfriend at the time...even when she found a metal shard...with her foot!

Ha Ha Yoshi, that reminds me of when i was renting a room at a mates house, i rebuilt a Yamaha DT400 in my room, i also had the whole top end of a 3500 v8 rover in there, my landlord / mate knocked on the door once for the rent i let him in he was gobsmacked he left the room and made the comment you need a women.
i am sure i have a picture of the messy room somewhere if i find it i will scan and post it  just for a laugh
BTW i bet that was real heavy to lift out of your room when done

To be quite honest Peter it was easier between three of us to carry it down like this...


than to try and carry the bare engine down between two of us....

plus it was nicer to work on the bike in the warm bedroom than outside where there were no lights at the time.
