Step by step

Yeh that is where I get my bits but couldn't find the springs or ramps when i asked them they told me that they dont have.
i've built 3 sets so in theory I have another set now.. as 3 spares..  :o problem is that they are differents sizes  :P

Ill have another dig around.. and yep they are about the cheapest I've found for bit and the adjustable air jets rock.  Though show and go are quite reasonable on jets, getting a quite a selection of them to.

Little by little, the bird builds its nest.

Now it appears that the outer K&N pod filters will get in touch with the tank and the RHS in addition with the side
cover. I have no idea other than cutting out the side panel and upholster the tank (which I honestly don?t like). Is
there any workaround for subject issues?

Red makes angled inlet stubs, around 10? angle downwards on them. You could also fit a cable tie around the rear rubber tank mounts to raise the tank slightly.

I just removed my oval K&N pod filters from my Mikunis because they DID NOT flow enough air.
Anything around mid range and the bike just ran out of go.
Also, if/when you fit them you will have to make cut outs in the sidepanels (if 1000 sidepanels are used) to allow the pods to clear them.
I have now fitted, for the time being, 50mm length bellmouths until I make a better solution for air filtration.
My situation is complicated as the top monoshock mounting point prohibits use of the standard airbox.

I have my outer pods canked at an angle to miss the sidecovers plus the sidecovers are spaced out a bit as well.The tank is jacked up a bit as well.
 
Thanks Grant. So if I would like to keep the pod filters I need Reds angled inlet-stubs.

Vince, the canking of the pod filters would likely compromise the airflow. But would possibly reduce the amount
of cut-out req?d on the side covers.

Is there any chance to marry the Miks with the original airbox?

Hi Jo,
I've found a pic on the interwebs where someone just shortened the original airbox. Another option might be to push the OEM rubber gaiters one rib further into the airbox openings. Using the OEM airbox might also help to support the carb battery and relief some stress from the engine rubber spigots, which will help for them lasting longer.

Regards,
Stefan

Every little helps. I'm sure there is a way to do it if you adapt and adopt some, more or all of the above to make it fit.
First time I have seen the slimmed-down airbox. Wonder how it flows. Plus it would be an SOB to stretch the original inlet rubbers over the Mikuni RS36s.

Hello Stefan,
this is exactly what I?m looking for! It would help to keep the appearance as close as possible to original.

I searched the www a bit and found out that Red has done some adaptors. They are visible as silver rings on the picture Stefan has posted.

I also found them on Laverdamania ? here they are shown on a 1000 SFC (picture is blurred ? but its self-explaining):

I think that?s what I will go for! Thanks for your hints and help!

I used to make the adaptors for the airbox rubbers but gave up on that idea due to an operational issue with mounting the Mikuni's on straight manifolds
Mikuni recommend that the RS carbs are not to be used at an angle over 30 degrees and when mounted straight on the Laverda head they sit at an angle of 28 degrees
that means that you have to lean out the float level in the bowl to stop them overflowing and thus limits the amount of fuel that is held in the bowls
I found that chasing Mark and his Miss J 81 Jota up Mt Glorious on my own 81 Jota with the Mikuni's fitted I would start to run out of fuel
so that is when I started to make the 10 degree manifolds to drop the carbs back to 18 degrees and thus change the fuel capacity in the bowls

I know a lot of people run their Mikuni carbs at 28 degrees and that is fine if it works for them but I prefer to run them at 18 degrees
works on our race bikes

Bloody piss-poor excuse for not catching Mark on Miss J. Going up an incline would put your carbs closer to level anyway.  ;)

Actually, the Mikunis wouldn't have fitted on my Jota without the angled manifolds. The tops of the carbs would foul the tank with straight manifolds.
 
That's what Red told me, only slightly less tackfully. I was told if I didn't want to strangle it or damage it running lean then I needed to use the pods and keep the correct bowl angle. Always best to learn from those who find an issue before you do. I would still love to run an airbox but it would need a lot of cut and shutting, best to make it as big internally as you can with a freely breathing filter element and easier to get at to clean. We all should remember what happened with the over oiled Uni Filter elements in the past.
 
I obtained new shims yesterday, and, to get them changed there was (of course) the chance to look right after the
suspicious cylinder stud.

The removal was not quite so trivial. I had to loosen the engine completely and lift it to get the stud past the upper
frame tube. The picture doesn?t show these troubles really:

Blame on me ? I found it was installed correctly!! When installing it back (the way it was around) I actually managed to
screw the stud in a little deeper. And annoyed me, because I didn?t notice that the upper thread length was identical on
all six studs. So went some of the Hours today for pure knowledge gain on it!
::) :-[ 8)

To be cont?d ?

Errr, what happened...?
You make it sound bad, I had a look back but could only find references to poor performance (although that could be considered pretty terrible  ;))

Hello Stefan,
I like the idea to keep the original appearance as far as possible. Which means having an airbox with a kind of panel air-filter
element, and, of course with the biggest possible volume (which is hard to achieve with the slimmed down airbox in your picture).

Hello Grant,
comparing Stephan?s picture ? original rubber inlet gaiters are connected to the Mikunis using Reds adaptors (not available anymore):

index.php



? with another picture I found in the www - which shows the original rubber inlet gaiters fitted directly to Mikunis w/o
Reds adaptors:

28432074617_4ea8311c92_z.jpg



... leeds to the question if this would work. Guess the risk that the original rubber gaiters tear is very much likely
(outer diameter of the Dell?ortos is 46mm vs 55mm on the Mikunis).
Alternatively I have to look for some suitable automotive rubber tubes.


So still a lot to mull over ?
(dunno)


Cheers
Jo

BTW:  What is SOB standing for?
