  2. Electrical Wiring Diagram For A 4rt

    in Montesa

    Posted

    Hi all, I am looking for the Electrical wiring diagram for a Cota 4RT 2008. This may be in the user manual?

    Can any body help me?

    a) A link to download one or.

    ;) Could someone email me one over?

    The wiring diagram is so I can work out the wiring for the (on the on the road kit). This is Headlight and indicators + a Digital readout unit mounted on the yoke.

    My email is pdjohnson@freeuk.com.

    Thanks in-advance for any help.

    Regards

    Paul Johnson.

  3. Fuel Leak On Techno

    in Beta

    Posted

    Hi Wayne, Have you tried this. Pulled the fuel pipe off from the tap. turn the fuel on then off. Dose the fuel stop if so the the valve is good.

    If not then the fuel will continue to flow into the carb and if on it's side stand it may weep out of the Carbs left side breather pipe.

    This shouldn't normally happen if the float is working normally.

  4. Info On How To Test The Stator In A Rev 3 2003 To 2007.

    in Beta

    Posted

    Hi All, I have just replaced the Stator in my 2005 Rev 3 270cc bike.

    This is a 4 wire stator.

    The Red Wire= Is AC supply to the CDI.

    The Brown Wire= is Ground return for the CDI.

    The Black Wire= Is Trigger for the Timing to the CDI.

    The Yellow Wire= Is AC to the Reg for 12 Volts DC to feed the Lights and the Horn.

    To test the Ignition circuit measure between the Red and the Black, you should see 321 K Ohms. This is one winding and neither the Red or the Black connect to Ground. Also I tested the Inductance of the Red / Black circuit. On the bike and within the magnetic field of the Flywheel. I measured 820mH. Outside the Magnetic field a massive 1.5H.

    To test the Yellow circuit measure between Yellow and Brown or Ground ( Brown is connected to Ground in the Stator) you should see a very low reading of 0.51 Ohms. Again I tested the Inductance of this circuit on the bike and inside the flywheel. I measured 2.25mH and of the bike ( outside the field) 2.51mH.

    I hope this clears up a lot of confusion about testing the Stator. I must state that the testing was measured at DC and it will be completely different when the bike is running as this is an AC Circuit and it's the Impedance that is important NOT DC Resistance.

    Hi.

    Can anyone confirm if Beta have got rid of their biggest problems and

    1: fixed the fuel leakage issues :thumbup:

    2: sorted out the stators so you dont need to keep replacing :D

    Ta

    Yes since 2008 they changed the carb and also the stator plate and the kill switch to sort out these problems.

  7. New Rev 3 Mikuni Carb?

    in Beta

    Posted

    I found a description of the drill mod:

    http://www.motoclubgiaveno.com/page12.html

    Unfortunately the description is italian (?), but the pictures are self-explaining.

    Hi all I have translated to english

    I hope this helps. You will need to read between the lines though!

    1) After having well washed with petrol totally dismantle the carburetor paying attention to positioning of all components.

    2) Punching the central portion of the cap processing Figure 1.

    3) Pierce cap with a peak of 2mm and use a small screw extractor as Parker.

    4) 's support of the measure noted caliber A channel of Figure 2.

    5) With a tip from 3mm to extend the hole released by the cap Figure 1. VERY CARFUL a stop at 1.5mm by the end of the channel.

    6) With a tip of 2mm. Making the new Bar B of Figure 3 until you reach the canal.

    7) 's aid of a compressor to clean carefully all the various steps of carburetor air blowing THOROUGHLY.

    8) With the dots lead to appropriate measures ( available in any stoe hunting & fisheries), provide fill the hole of C Figure 3

    and the channel for processing of Figure 1.

  21. Trials In Tamwoth?

    in UK Trials Talk

    Posted

    Hello All, I have just brought a Beta Rev 3 270cc 2005.

    I live in Tamworth, Staffordshire.

    I found out yesterday that the Olympia park in Bickenhill had changed to a Motocross only this was done about 17 years ago.

    I use to ride my motocross bike back in 1988-1992 on the ruff ground next door to the above park, they wouldn't let on the Olympia park with my bike :-(

    Now in 2008 I have a trials bike and I still can't ride it at this park :-( can you believe it!

    Please help... where can I practice locally around Tamworth?

    fingers crossed Paul.
