Well at 11200 rpm, it kind of cuts out. I was actually lazy to remove the rings in the exhausts... ;D, probably should have done that.

Is your speedo limiter working fine? Otherwise it will cut rpm at 11000rpm approx.....

Well maybe 11000 then...so there is a limiter! I was not sure about that...so how do guys say they rev it up to 12-13000rpm? From the feeling I get it can go more...its probably bad for the engine though :-\

there is a speedo limiter active only when going over 180 or 0 (standing)
I had the same problems with my 3ma3...I couldnt rev higher than 11000rpm even when I was going with 40km/h
I think my rev limiter sensor is broken

Rev limiter was on my mind to, only normally a rev limiter kicks in at approx 10.500/10750rpm.
You did say that you can hit the 11.200rpm that is way i did not mention the rev limiter (sorry)

The rev limiter is only active when standing still (as Fotis says 0kmh) ore when you drive, it will not allow the engine to go over 180kmh
everything between lets say 10kmh till 170kmh is full power and your engine will rev till 12000 ore 13000 rpm if she can.

You can test the rev limiter easy, give full throttle in second ore third gear let her rev to max, and if its the limiter you will never get past the 10.500/10.750 (perhaps on yours 11.200rpm) but if it is still revving slowly higher to 12000 or 12500. you know it is something else

The rpm limiter is in your speedo meter, it is the connector with 3 wires make sure you connected them. you can disamble the rev limiter by removing the metal tap in the speedometer or remove the chip from the speedometer

If you take out the chip is (easy two screws) connect it outside the speedo meter. it has to be connected to give the right signal.
If you take out the metal tap in the speedometer, it is a bit more work. but you can leaf the chip on its place. but you still have to connect it.

The same kind off problem can acquire if you have the tps sensor 180 degrees wrong, where the wires are coming out of the tps sensor they have to point to the engine
this way


And of course the speedometer has to work, but that will be working, we don't want speed tickets from the police ;D

Louis...I do not think it is possible to place the TPS sensor wrong to get the wires other way around.. ;)
Is where yours is positioned on the pics?

Yes, you can put it the wrong way around ;D
very easy.



No it is not the position where the tps sensor stays it was taken fore the picture to show that it can be mounted on two positions.

You carb looks like new by the way compare to mine:
This is where the sensor is positioned right now, do you know what turning it to left-right does? Should I leave it the way it is right now?

in theory, moving it to right the cdi will choose a different ignition map early
moving it to the left the ignition will choose a different ignition map later
(deepens how you look at it otherwise its vice versa) ;D

But don't worry moving it to the max or min will not affect you max hp  (the turning will be not enough)

the way it is standing now, is fine

Hi Louis i am back was a couple of days in the hospital with a knee op but all is well i have not had much time to work om
n the bike as yet but will be tackling it soon i did manage to set the float level as Edd explained and it made a huge difference but now i need to sort out all the other bits and pieces the fuel consumption has improved quite a bit as well as the bike response but will post the coming events of my long and hard work later and keep you updated and once again thanks for helping me out with this bike i have almost got it right it still boggs down a bit under 4500 rpm but we do allot of long distance traveling


Many thanks'Deon

Hi Deon,

Nice that you have the carbs all most right, do you still not have the airjet system??

Bogging at low rpm's is a problem a lot of 3ma's have. will be a challenge to get it bog free ;D

Let us know how it goes

Louis

Hi Deon,

Think your gearbox is getting some pressure from the barrels and the only way fore the pressure to go is true the breather pipe taking the oil with them.

cousin pressure in the gearbox can be :
-worn crank cases (bend on the interfaces)
-worn crank seals (clutch side)

But I'm not really a expert on this, never had pressure in my gearbox

Perhaps some body on this forum has a good answer for this problem

Sorry, can't help you on this one
