side mounts
i have taken a closer look at the side mounts..
one has thread in it i think its m10 x 1,25
but the other is empty... and using there a bolt is difficult because it only has one plain side.... see pic...
any one ideas how to use it??

The mounts on the bike quite often bet broken off during the bike accident, so assuming your engine came from a crashed bike then its quite possible
that the crash could have cracked the mount and its now only properly failed.
Find a local fabrication place with an AC TIG welder and they should be able to weld it back on for you.

Chris
Can you think of any other reason wy it could have failed?/ broken??
this afternoon i'm getting the engine out (completely)
as you have seen i didn't make a cradle
what would you do? just weld the old support back on or would you make a better design??
i think i have maken 5miles on it...
the reason for faillure is gonna be that i drove on a bad realy bad road with loads of vibrations on the suspension etc..
Think that has stressed the mount...

Bad roads shouldnt unduly stress the engine mounts unless the chassis is flexing a lot, in which case you'd need to look into strengthening the
chassis up so it doesnt do that.
Have you got a pic of your complete engine mounting system before it broke?

well
basicly
it has another foot like you see in my archive at the same side but on the opposide of the cilinder..
then in front of them (the 2 foots) i have like a horizontal foot soow one side cant twist while braking/acce the other side cant while
cornering....all of them limit the travel on an bump etc..
the road was very bad because my front suspension was hardly working (to less weight??) and was shaking allot...
maybe up to that the already shock it had while in the donor vehicle crash..
and the mount came off..
will make foto how it was...

yeah funny aren´t they?
do you mean i have the engine not properly secured or do you mean you realy are blind 
the oranje what you see there is the mount with one m10 BOLTED TO THE CHASIS..
maybe now you see an mount or bracket..

No I wasnt being sarcastic
I can see the orange part but its not clear that its an engine mount or how it bolts onto the engine, any chance of a close-up picture thats a bit
clearer?

OK, Ive just had a look at the entire pic and I think Ive got an idea of how youve mounted it, is it something like this shown in red?
Image deleted by owner
If so then I would certainly have a look at putting something in additional to brace the top of the engine, two bars picking up on those top engine
mounts going across the chassis and picking up on the side chassis rails would be ideal. Apologies if this is wrong, like I said its not that clear
from the pics.

yes yes...
in fact what you did is almost what i have done..
but only at one side...
See my Pic...
In fact just what you did and yes, i only have supported it on the lower side of the engine..
i'm working on the horizontal bars..
but still sits with questions..
welding it to the chasis rails or bolting??
how do i put it nicely?? how do i now measure / adjust if the engine isn't 90degress with the chasis??
and how can i use the empty holes on the sides?? only one of the 2 has thread in it??

I would say that from what I can see, they do need to be a fair amount stronger, probably using box section rather than angle.
Looking at your main engine pic in your archive, I would think two 1" box sections going across the chassis and picking up on the side chassis
rails will go a long way to helping, Im not sure what you can do if the engine isnt 90 degrees to the chassis other than to either still make the bars
90 degrees but weld on a mount at the right angle, or just live with having the rails slightly at an angle. As to fitting them, just make up some
mounting plates, weld those to the chassis side rails then weld similar plates to the ends of the rails so you can bolt the rails into the chassis,
otherwise if you weld it all in it will be a nightmare if you ever need to remove the engine!

Well Guys
This is then the pic of how it now is..
should i go any furhter??
when looking at the haynes manual Chris i also saw that i wasn't using a mount designed for engine mount...
my engine has only 4 at each side.. 1 at the back and 2 between the heads..
now days i use 2 at each side + 1 at the front right (isn't desinged for it..)
should i try to use more of them??
i think that i can its now easy to join/weld more trianguels wich i then bolt with a piece of tube (spacers) to the bike..
in the pic you see the bolted bars
Edit:
on the right side unther the bar you see another mount for example at the other side there is one 2 (there it needs a huge spacer)
then in the middle where i already have one..(behind the bottle) there is another one

That looks a lot better
Its hard to say if you need more or not to be honest, not many BECs use every single engine mount so as long as you've picked up on the major
ones in each particular area of the block then it should be fine Id think.

I know nothing about engine mounts but I'll give you some advice son, and that's: you don't want to mess with the Spanish Guardia
Civil!!!

Yeahh
that's true....it looks like always they wakeup with bad mood 
well the good news is that i also found my electrical pedal the pot (variable resistance) bad in one particular area..
and guess Chris?? its the part a bit further then when pulling away..
soow that's also a reason wy it shook sow heavy.... it was bad there that means that the resistance wasn't nice
it varryied very much..soow my throttle kept moving.. you could see it as some noice on the line....altouhg its deffinitly the pot...
i now have places a new one...and that one does a bit of the same but nearly when you give full throttle..
anyway will buy some expensive/good ones sow they don't fool the computer anymore with there position...
