Dall'esperienza di molte persone che hanno già montata in bici da anni .....:
* ??? Aumento del consumo di energia dal motore .... semplicemente "trascurabile" ... e nessun problema con la pompa di spostamento ... (sull'ingranaggio della nota EVO 4T c'è il metallo .... e non il termoplastico. ... che comunque non promuove promozioni anche su 2T)
* Nessun problema con bici da corsa con basse temperature ((-20 gradi C *) .... una volta a temperatura ottimo ... troppo freddo ... almeno per quello che significa ... molto freddo in ITALIA ... !!!
* Risultati eccellenti .... anche nelle condizioni di lavoro più esasperate e pesanti del motore ...?.. la temperatura massima raggiunta .....
scende di 15 gradi C * !!
quindi il motore si sta comportando in modo ottimo e quando si arriva a quel punto la differenza è sentita e molto ..? .. troppo!
Quindi per EVO 4T ..... fortemente consigliato !!!!
Guys....
I'm going crazy to look for a bigger impeller kit for my Beta IV 4T, since I have to do this job on the bike I would not like to mount the original plastic impeller ......
I'd like to fit an aluminum impeller like the one in the evo 2t kit .....
You will not believe it but I can not find it anywhere ....... but how ... the bike build it in Italy ..... but I live in Italy
Does anyone know of any manufacturer that has the model for Evo 4t ????
Hello to all
Ragazzi ...
Sto impazzendo a cercare un kit di giranti più grande per la mia Beta IV 4T, visto che devo fare questo lavoro in bici non vorrei montare la girante di plastica originale ......
I piacerebbe montare una girante in alluminio come quella del kit evo 2t .....
Non ci crederai ma non riesco a trovarlo da nessuna parte ....... ma come ... la bici la costruisce in Italia ..... ma vivo in Italia
Qualcuno sa di qualche produttore che ha il modello per Evo 4t ????
I was able to replace the water pump shaft and seals on my 2009 4t just by carefully unscrewing the shaft (24) from the gear (22). The gear will not fall into the engine. I used an adjustable "Crescent" wrench to grip the flat on the shaft, much better than the weak special Beta tool. Take care removing the seals, you do not want to damage the aluminium bores. Grease the seals and shaft before installing the new shaft. I used a set of long, narrow, needle nose pliers to hold the gear up enough to engage the threads of the gear and shaft.
Of course, the engine will have to be dropped down-,remove exhaust pipe,separate carburettor from air cleaner, let the engine hang only on the swing arm bolt. Lock the crankshaft at TDC on compression stroke with the locking bolt, first remove it's copper crush washer. Remove the valve cover. Loosen the water pump shaft from it's gear, do not remove the shaft yet. Remove the cam chain adjuster. Remove the cam sprocket from the cam, then remove it from the chain. Tie a string or wire to the chain and lower it into the engine, the chain will stay on the crankshaft's sprocket. Slide the ball bearing (14) from the camshaft, then remove the camshaft. You can now unscrew the water pump shaft by stopping the gear from rotating with a straight bladed screw driver. Since I'm writing this from memory it would be best to consult the 4t Shop Manual that's available online. Take your time, I would allow about 6 hours to clean the bike and complete the work for the first time. Good luck.
Cheers, Greg.
whouwww?? ..... !!!
. ....Greg.....
Congratulations and thanks for the reply ...... really complete and professional ?? !!!
But I must admit that reading you also scares me .... ?? ..... because it is not as simple as I thought. ....
ok ... just a few words ....
.... I decided that this weekend I'm tired .... ??
and I do not feel like trying ???
But next week .... you will dance and I will do the job as You explained to me ?? !!!!
If I succeed I will post the video of my "Clarabella" ....
again roaring .....
Otherwise. ... will mean that I made a mess ....
????✌✌
Boys ..... I .....
actually ... it's ... a candle with iridium electrode technology ...
in fact these candles have two characteristics compared to conventional copper:
thinner electrode and longer isolator ......
? ..... that's why in the descriptive notes Beta 2018 .....
the betas
"commercial man" ....
"they write a new candle with a longer electrode"
???????
Quando ho fatto uscire una piccola quantità dal "foro di gocciolamento" ho cercato di sostituire la pompa dell'acqua. (La flebo non è ancora successo, quindi non l'ho ancora sostituito).
il manuale dice di sostituirlo a circa 60 ore, ma presumo che sia sottoposto a un uso estremo della competizione e dubito che un utente "normale" mantenga la manutenzione agli intervalli raccomandati.
Credo che il modo migliore sia rimuovere il radiatore e i supporti laterali, rimuovere la piastra paramotore e tutto tranne il supporto motore posteriore, rimuovere lo scarico. Allentare il morsetto del giubileo del carburatore e inclinare il motore verso il basso. Quindi è possibile rimuovere il coperchio superiore della testata e accedere agli ingranaggi che azionano la pompa dell'acqua. Avete il manuale di servizio?

I like your strategy ....... soon ...
next weekend .... I will try to fix the little ?
Perfect received?
In fact, I already asked for advice on a fault with my bike, even if there is someone handy BETA EVO 300 4T I would be grateful if you read my post in the
BETA BIKE collection.
I realized now that I did not answer your question:
My Beta did all these hours / km in an exact 1 year time period.
I've never had to replace any piece until now.
Cylinder and piston have never been touched and are still ok .... the engine runs really well !!
I changed only a rear tire .... and honestly now the one that mounts is already 60% wear !!!
I also have to change chain sprocket and brake pads ..... we can say that this is the minimum with this use .... !!!
Of course I have always taken care of the oil-air-oil change.
Still original candle. ..... I will change this too.
yes, there are actually 300 hours of hour meter + at least 50/60 hours before I put it on the bike.
But do not be impressed ... because there is a trick !!!??
Not all trial hours - off-road.
The truth is that I like the trial bike so much ..... that even if I have a car and a road bike ..... I use the BETA EVO 300 4T ... every day to go to work while staying in feet on the footboards .....
Every morning I go to work at home, then I come home for lunch and then I go back to work and back home in the evening.
So I'm on the bike 15 minutes x 4 times a day, in short, they are 1 hour a day x 5 days a week ..... then 20 hours a week and for 11 months (even with the coldest extreme do not give up ... .mi stop only for snow and heavy rain .....) make 220 hours.
Here are the remaining until you get to the total are TRIAL ..... at least almost all .... because there are also included mountain tours ......
I found one thread on this- but it wasn’t really clear to me. I have not had any experince with these engines yet.
I believe I am due for a water pump seal replacement. Perhaps the shaft should be replaced at the same time. I could not discern if the water pump shaft can be removed without the gear driving it being disturbed. It appears that the engine needs to be at least pivoted down to remove the cam cover, and probably that would be the safer way (?) but who has done it ‘in sutu’ and just removed/replaced the shaft and seals?
thanks for any help.

Hi ..... I would be interested to know if really when removing the impeller shaft pump ..... keeping the motor mounted on the vertical motion ..... drive gear falls down inside .....
Hi guys: ... Today while I was returning from a ride in the woods I stopped to do ..... .... "a prostatic discharge" .... Unfortunately when I went to resume the bike I noticed that .... SHE HAD THE SAME IDEA .... just put in motion lost water from the gasket HEAD-CYLINDER right side ...... exactly under the pump impeller casing . Lose only with the engine running and only at the minimum .... if I give gas stops losing .... I think it is excessive wear of the oil / water seal + pump impeller shaft. The leakage of water comes out with a good probability from the spy hole that allows precisely the water no longer held by the seal to escape and do not go to contaminate the oil. Well ....: fl ^ -g .... ..... since I have largely spent the 360 hours on this bike I think that how to say "there may be" .... Question: You think you can replace - impeller shaft - water / oil seals just disassembling the impeller cover ??? I have a doubt about something in particular or .... when I turn the spindle shaft .... there is no risk that the gear falls down into the carter .....: bho: bho ???
