Beta

New impeller fan and thermostat works. Still overheating after about 20 minute Thanks in advance for any suggestions. Cheers

During the last few rides on my 2016 Beta 300 4t, I started smelling fuel. I have a clear tank vent line and I can actually see gas bubbling up the line. A 1/4" or so of air will be followed by a 1/4" of fuel and so on. It sort of slowly oozes out the top of the vent line. A long time ago I put on a long vent line because fuel will spill when pointing sharply down hill and ran this a long time before this issue. See picture. The fuel line is not too near the exhaust. The bike is not overheating and the tank did not feel particularly warm when I put my hand on it. The tank does not have to be full for it to happen. It does it with and without the vent fitting on t…

So today, whilst on a training day (typical), I dropped the bike and the clutch hose sheered off at the reservoir on the handlebars. End of training day and an early lunch! I'm trying to source a fix before the weekend, I see that the Rev3 <06 are listed as different to the 07 and 08 - and everyone is out of stock of the 07 and 08! Does anyone know if an Evo one might fit? Alternatively, I've though about trying a repair with a compression type fitting on the end of the existing hose if I strip the braiding off but I don't know what the size would be called (M10...something?) Would be grateful for any info from anyone who knows, thanks.

The official Beta Workshop Manual does not have a wiring diagram. I've done some looking but not successful so far. Can anyone provide one or a link? THANKS!

I might have the chance of a 2018 Evo 200. I haven’t been to see the bike as it’s a couple of hours drive away. I’ve seen a couple of photos but not that clear, the chaps going to send a video tomorrow. He says he bought it used and doesn’t know it’s history. For this reason, he decided to have the engine rebuilt at a local shop, top and bottom he says. Im a little concerned that a four year old bike would warrant or need a complete engine rebuild, does this sound normal? Is there anything in particular I should look out for? it’s quite well priced but I’m wary, for what reason would a bike that new be likely to need an engine rebuild? Does it mean it’s probably…

Good Afternoon, I’ve been advised elsewhere on here that fitting a larger clutch slave cylinder to my Rev3 250 would help with the ‘light switch’ on/off clutch. I’ve done a quick look around the web and come up with nowt, can anyone advise where I might find such a thing? Or what specifically I looking for? Thanks.

Hello all I've been offer a new bigger 30mm clutch cylinder for my factory Evo has anyone fitted one and there thoughts over the standard one. Many thanks

My bike would not start (after previously starting easily and running fine) and I've spent many hours trying to figure out why. It had a spark but it was weak! Section 3.10.1 "Testing the Ignition Stator" in the official Beta Workshop Manual says: The stator winding must be inspected while the temperature of the component is ap- proximately 20 °C. The inspection may also be performed with the generator coupled to the engine. Disconnect the 12-way black connector between the generator and CDI and with the use of a multimeter, verify that the resi- stances read between the terminals shown below fall within the prescribed range: bla…

Hi all, just taken the carb apart for the first time on my 2010 Evo 4T. Couple of questions. 1. this small part fell out from somewhere, however I no idea where! Any ideas? 2. Pages on this forum talk about the correct tuning of this carb. The jet sizes and mixture screw are now setup. However they also talk about a spacer and needle position. The needle position is supposed to go from 2deg to 3rd and the spacer is to be removed. Anyone know how to set the needle position and spacer? I don’t know what these parts refer to…?

Afternoon, Can anyone point me toward instructions on how to change the fork oil on 2008 Rev 3 250 please? Cant seem to find any info online and haven’t done it before, thanks.

Hi there, c an someone tell me whether the side stand on the Beta EVO 300 4T is made of aluminum or steel. Thank you, regards Bernd

anyone ever rerouted the wiring on an evo , the carb and fuel switch area is a very tight space with cabling coming down there aswell cheers

I've got a 2020 EVO 300 with about 200 hours on it, always had an inline fuel filter and air filter cleaned and oiled frequently. Recently I started having an issue with it getting an erratic idle. It seemed like the idle would rise after a long hard climb (say 500m to 1km). It would also rise on long descents. Performance otherwise was just fine, nice crisp response over the whole throttle/rev range. I removed the carb and thoroughly cleaned (including removing the jet tower) and blew out all orifices, checked vents, checked float height and needle sealing. Also checked that fuel is not overflowing when the front is raised (lifted wheel ever higher until it ove…

Hi Guys and Gals, Can anyone tell me what the real world riding difference is between a 200 and a 250 Rev 3? I’m new to the sport and searched for a 200 but none were about so I ended up with a 250. I have read that the 200’s, either Rev 3 or Evo are the ‘holy grail’ for the beginner Clubman rider with the ideal spread of power etc. Is there a big difference between the two? And if so are there sensible alterations I can do to the 250 to make it more like a 200 to ride? I ask this because at my standard I don’t need the power it has and in some ways it would be helpful to have less so I can master technique without worrying about the bike getting away from me so…

hi all , my sons 2010 evo 125 is having some issues can be a bugger to start , would rev tick over then just die then kick and kick no joy tilt bike to side with fuel out overflow would help get started again but same issues I've checked plug which was new last outing 2 weeks back as same issues and is sparking , stripped carb and a jet was a little blocked all cleared with an airline started back up and same issues wouldn't idle off choke but once bike warmed up by keep revving /blipping to intervene or riding it down lane it ticks over nice and only get a dip in engine note every 30 seconds or so at idle don't hear or feel a dip when riding it around …

I need a piston and seal kit for my rear brake caliper and I have not been able to locate. Is there a replacement caliper from something else that would interchange? i ant to ride my bike again.

I need to jet my carb for sea level. This is what's in it. Pilot 35, Needle 3, Main 145. I have a 45 pilot but not sure which main to use and don't want to buy six of them to tryout. Anyone willing to share their jetting specs for sea level? Thanks!

Hi, I'm looking for the (dell orto) carburator jetting for my 94. Could you help me please

Hi there. Just upgraded my old 2012 Evo for a newer 2020 model. It already has a press type kill switch fitted. On my old 2012 bike I replaced the dreaded original frame mounted kill button / headlight switch unit with a lanyard type kill switch. I loved it and it saved me on many occasions when I parted company with the bike. However I constantly felt it was easier just to stall the bike rather than pull the lanyard every time I wanted to stop the engine in a non emergency setting. So on this bike I want to fit a lanyard kill switch as well as the standard kill button. I have taken a photo of the existing kill button wiring. I was planning on just cutting into the …
