Gordons frame kit
« on: September 13, 2012, 11:16:35 PM »
Having taken about half an hour to get the engine out of the F2 frame ( and all there was was the engine and frame ) together with a lot of cursing, I decided what I needed was a "Gordons Frame Kit" to get the bugger back in when re-building the bike. It also means that I can re-build the engine in stages, rather than one big lump. Had a look at the photo's of the kit and thought shurely you can do it easier. Here's what I came up with.Made 8 top hats out of 25mm bright steel tapped m12 down the centre. 12mm stainless threaded bar, nuts and washers.  Frame cut and inner seam filed off. Top hats fitted. Assembled, ready for welding.

Thats a very good idea i had a bit of bother getting my engine out last week ended up taking my exhaust studs out to clear the frame,not looking forward really to trying to put it in once the frame is all nice and painted it will be getting covering in thick tape,

Where can you get this kit from ??

I did my own frame mod back in 1982



I had to have a new tank made for it but that was my intention anyway

I have read on the american sohc site that some people have done away with with the frame braces alltogether, its not something i would want to do, but the question is are these frame braces required at all ?. How much stress are they under ?. i am thinking of just using bolted on sleeves, would this be strong enough ?, or is something more substantial required ?

Some of the kits back in the day were a bolt in bolt out affair with no welding,  i think Carpy still offers one?,

and like you have said some people ran there bikes with out them?,

i think a bolt in kit would work ok i think the back bone is more than capable of taking the strain  ;) i have the Gordon's kit and it has been a great help  8)

cheers Mick.

The kits can be had from the US site - just have a look in the classified/for sale section.  I think Gordon himself is involved in the process (he stepped out for a while).

As for the braces, I rode my K2 round for a while without them and didn't notice.  I gather racers used to remove them - because it allowed top end development work without engine removal - without any ill effects. 

If you're going to use the bike for normal riding, you should be fine without the additional bracing - but be aware that you might put off some future buyers if you don't replace it with something.

Oddjob, did it with stainless threaded bar, nuts and washers for that very reason.

Bitsa & Stu i have the original style Gordon's frame kit from the USA fitted on my F1 750 and its much easier doing top end work now rather than having to take the engine out to do it  8),

once its fitted & welded & painted you would think its standard fitments  ;)

Archie get making some think you may have a market for them  :) cheers Mick.
