Two years ago Gerhard gave me a shopping list for Ebay. To change the carburettor.
I bought a:
- 900 monster carburettor set (Mikuni)
- 900 SS air intakes
- 750 needles
- 750 main jet
Last two of Dynojet 1 research.

1 Get rid of the old Weber

Don't mind the background

Adjusting the valve play.




Fitting the 900 ss inlets






Fitting the Mikuni carburettor




Next time I will have more detailed photos of the settings!

We also did new wheel bearing in the frontwheel.
Trying to get the right front disk on line (no shutter)
I bought two new front disks, but they seem to be two new rear disks :thumbdown:

Setting the carburetttor up. Screwing the air needles al the way down and then up 7 HALF turns (so 3,5 full turns).

Starting right away :thumbup:

We will finisch the job over a week of 2.

Nice, all I need now are K&N filters for the Mikunis.
Does anyone know which filters to order???

Thanks in advance and hope you enjoy the pictures

I used the Monster grip.

As you can see in the first from last picture. If you look closely you seen the two throtlle wirers and their connections :thumbup:

Gerhard, what to do with the airbox. Make one like you did?
Use a K&N standard box or just the K&N Filters.
See Ya

info / questions:

as the carb is higher than the Weber the airbox will become smaller and more restrictive so I`d say a K&N filter is a must if you take the airbox solution. (although I never really suffered performance loss)
Can you work with glassfibre ?

Regarding the open filter solution. How bad are noise level controls in NL and how fast do you drive ? Bauke also used sport filters with his Keihins + other mods and he really had top speed problems. The issue was probably that the carb stands upright while the air comes from the front. At high speeds wind will become so high you may have an underpressure at the carb inlet and the bike will run rich.
So my suggestion would be to make a sort of shield around them just to cover the filters rear side and maybe a little bit of the sides. I`d say this shield should not have more than 3-4cm distance to the filters. Of course that`s just my theory.

I know though that some kind of shield was available from some sport filter manufacturer. I`ve seen something like this once.

PS you`ve got mail

Open filters are a lot louder when you ride the bike (could definitely hear them more than my Conti 2:1 system) so noise control could well be an issue if the noise test is done off idle. At idle there is not that much difference between sport filters and a modified airbox.

Thinking about it my bike used to run rich at high speeds ( you could actually smell the carb over fuelling )

but to be honest the performance was not noticeably worse (my 750 had a few compression issues as well so I suspect these masked any other problems!)
