Engine swapping.

(1/2) > >>

mick:
This is what I've been up to this past week  ;)  I took the engine out of my F1 to fit in my 1970 cb750, the engine in my old 750 has been smoker on 1 or 2 pots for a long time and is burning oil,

my F1 has been off the road for a couple of years and needs a few things to put it back on the road , so I thought I might as well use the engine as its a good one,

I had to take the exhaust studs out to fit the earlier type stubs,  that was a job in itself  ::) I used the double nut method on some of the studs & a stud extractor on some of the others, 2 of the studs sheared off so I had to drill them out and helicoil the holes,

the rest of the engine swap went smoothly but these engines are flippin heavy and the take a bit of wagglin in and out  :P,

there was no one to help me so I had to use a van wheel rim and a board to get the engine out onto and back in again  ;) cheers Mick.

Hi Mick, - just up the road from you. Congrats on getting those studs out - not a job anyone would relish especially when they start to snap off - didn't let it beat you  :). Happy to lend a hand and find out a bit more about these beasts in future if you like...
cheers

 ;) good going its always hard work lifting them engines out, no wonder them japs got slanty eyes and buck teeth lifting them lumps all day.  :o exhaust studs  don't even go there I even wrecked a stud extractor on them buggers, there is a f2 motor in my sidecar while I rebuilt the k0 motor I said id swap them back over when the f2 blows lol I hope it lasts forever I dread the thought of changing them back over , I'm still suffering after rebuilding another k0 motor last year its still not finished I must be getting old lol
p.s is your bike a k1 you say its a 1970? must be an early one
