Sooo leute ich hab eine offizielle gelaekte Presseerklärung für neue Motoren ich werde jetzt hier häppchen für häppchen veröffentlichen :D Kommt richtig viel neues

The new model carburettor will be called VHSB34 “XS”
It is still a Dellorto fixed jet style carburettor and looks the same on the outside, but internally it has been completely redesigned, specifically for the engine.
Benefits are:
• Significantly improved throttle response for the driver
• No longer necessary to apply the throttle slowly
• More user friendly for beginners
• Experienced Rotax drivers will have less advantage over beginners
• Carburettor is far less sensitive to changing atmospheric conditions
In Junior Max, Senior Max and DD2 classes, it is not compulsory to run the new Carburettor - the choice is yours!

soooo der nächste PUNKT.....

New Ignition System
A totally new Dellorto ignition system will be introduced.
All engines within the range use the same ignition system, however there will be different “Electronic
Boxes” specific to each engine to give optimum performance & usability.
• Micro Max / Mini Max / Senior Max all use the same Electronic Box
• Junior Max has a specifically programmed Electronic Box to improve the engine in the RPM
range between 12,000 to 14,000 RPM (this will result in less performance variation from engine to
engine)
• DD2 has a specifically programmed Electronic Box to improve the reliability of the engine
(detonation issues should be no longer).
In Junior Max, Senior Max and DD2 classes, it is not compulsory to run the new Ignition System - the
choice is yours!
This new Electronic Ignition System allows Senior Max and DD2 to run an Electronic Power Valve!
Electronic Power Valve


Electronik Powervalve
The Power Valve will now be operated electronically and will open at an exact RPM irrespective of engine
condition, temperature, carburation, condition of exhaust matting etc...
The driver can choose between two different RPM settings for when the Power Valve will open:
• Senior Max 7,600 or 7,900 RPM
• DD2 8,800 or 9,100 RPM
This system will be far easier to use and requires less technical assistance for the proper functioning of
the Power Valve.
At Engine Start-Up / Idle the Power Valve is OPEN…meaning it will start and idle easier. The Power Valve
then closes at 3,000RPM and re-opens at the exact RPM chosen. Upon return to the in-grid the engine
will continue to idle once below 3,000RPM again, and the Power Valve returns to the open position.
In Senior Max and DD2 classes, it is not compulsory to run the new Electronic Power Valve - the choice is
yours!
Please Note: You cannot run the Electronic Power Valve if you do not run the new Ignition System

Für mich klingen die Neuerungen, dass noch mehr Elektronik an das Kart geschraubt wird... Da lassen wir uns mal überraschen, wie das funktionieren wird und vor allem wie lange... ;)

Außerdem werden die Neuerungen mit Sicherheit absolute Schnäppchen sein :ironie:

Sorry habs doch sein lassen gabs für viele foren ärger und wollte den hier ersparen. Deswegen poste ich den Inhalt.

Exhaust System
The new Exhaust System will be more durable, lower noise and slightly lower weight.
It is no secret, the current exhaust system is no longer up to the task and we have far too many failures

Exhaust Socket
The new Exhaust Socket provides more accurate sealing of the exhaust system. It is easier to fit & install for all different types of chassis. There are different types specific to each engine.
• Micro Max 18mm Exhaust Socket (compulsory to use)
• Mini Max 20mm Exhaust Socket (compulsory to use)
• Junior Max, Senior Max, DD2 Unrestricted Exhaust Socket
In Junior Max, Senior Max and DD2 classes, it is not compulsory to run the new Exhaust Sockets - the choice is yours!


New Piston
The profile of the piston is being changed slightly.
Benefits are:
• Reduced running-in period (only one session)
• Reduced wear rate meaning longer life between rebuilds for the user.
Rotax only recommend upgrading to this component at your next engine rebuild.


New Conrod
New Hardening Procedure enables a new light weight design and two lubrication slots. This technology comes from the Sea-Doo sector and results in far greater life of the Conrod.
Rotax only recommend upgrading to this component at your next engine rebuild.


Optimised Crankshaft
New engines will be supplied with sliding seats for the Main Bearings. This means there will be no need to get a new engine pulled apart by an engine tuner to get the bottom end ‘freed up’. A new engine will have race winning performance out of the box.
Rotax only recommend / advise that you upgrade in case of failure of your existing crankshaft.


Engine Appearance
The new 125 MAX EVO Engine Series will feature Black Coating on the crankcases and Red Coating on the Cylinder Head. These are strictly visual changes only & have no effect on performance / reliability etc..

Puh das sind mal ordentlich viele Neuerungen.
1000€ für alles durfte wohl nicht reichen =)
