Will F1 motor fit into K2 Frame?

[Sam Johnson]

Gents,

I have got my hands on an F1 motor in good condition, my question is
will it fit into the K2 frame and what do I have to do to fit the original
4 into 4 K2 pipes to it.

Also any ideas as to get the motors in and out of the frames would help.

Kind regards
Sam

Hi Sam, yes the F1 motor will fit in the k frame , you will have to take out the 8 exhaust studs and replace with the 4 exhaust stubs & 8 posi head screws, i have done it with my 1970 cb750, as for getting it in & out me & my son have got it down to a fine art just lifting them in & out others have used trolley jacks with some wood under the motor so you don't bugger it up ,  cheers mick.

Mick,

Got the one out of the 'donor' F1 - cut the frame away!!!!

Engine is now on the workbench and I have just managed to remove the exhurst studs with heat, diesel and gentle tapping.
and of course the old '2 nuts - well in this case 3 nuts method'
I will now try and check over this motor to make sure it IS in better nick than the one it will replace.

I will try a plug chaser down the iffy number 2 plug on the current motor and see what that does, then get that motor running
right - if not then its SWOP time. I don't think I will be cutting the frame to get it out, how did you get the exhurst 'STUBS' out on
your K2?  I am told they are held on by cross head screws (must chew up very easy).
Thanks for your interest.
Were abouts in Lanc's are you? I live just outside Warrington.

Hi Sam, i'm in Lancaster just up the road from you , you will probably need a impact driver & some patience to get the exhaust stub screws out , cheers mick.

Hi Sam,
         I have a large metal philips T bar, I usually put it on the screw, hammer like hell for a while and then use leverage, they generally come out !
I live just down the road from you in Great Sutton.

Cheers
