Beta

I haven't put it on the scales but I have the impression that the weight distribution of my 2013 EVO 300 is biased towards the rear. Sag and spring rates (stock on the front, uprated on the rear) seem good but I need to push down about a foot in front of the lowest point of the frame to get the front and rear suspension working together. I'm tempted to drop the fork through the yokes by a few mm to put more weight on the front but, being a total novice I don't know if a bias towards the rear is considered a bad thing? Any thoughts?

Does anyone know if the lower shock bolt and special nut on Rev3 2000 is the same dimensions as on the newer beta rev3 models 06, 07?

Hi I have a 2013 Beta Evo, had it from new, very little use (5 trials a year on average, give or take) and when it has been ridden it's just the easy course. Just before Covid started the fork seals went so I had them replaced by my local Beta dealer. I did 1 trial then lockdown struck and the bike didnt see any more action until November last year. I did 1 trial and the forks seals were leaking again. I have had them replaced by my local dealer again and done 2x easy trials and now they are leaking again. BUT also, when the bike is sitting on a stand in the garage doing nothing, the oil is pooling underneath almost as if its pressurised and pushing the oil out …

YO dudes! Read the manual and it might as well be in Italian? Bike runs good but the idle speed is excessive, how do you adjust it without surgical tools? And yes, the throttle cable etc. is all functioning like all good domino's do!

Hi, I really need some urgent advice (trial booked tomorrow!); I'm changing the leaking fork seals, I've done the right fork (rebound) no problem but now that I've got the left fork disassembled I can't work out how the spring comes out. I need the spring out to measure the correct air gap for oil quantity. I've removed the top cap and the conical plastic spacer underneath but there's another cylindrical plastic bush on the inside of the fork tube that the spring appears to be seated under. This plastic bush does not seem to come out, can anyone help please?

Hi, I have a technical question concerning the front suspension legs. I just replaced the oils seals of the front fork of my beta Rev-3 2008. I took everything apart, cleaned everything thoroughly, reassembled them with the new oil seals and put 350cc of oil in the left fork and 370 cc in the right one (according to the prescriptions). But then the problem comes along. I first tightened up the right fork plug when the leg was totally compressed, so the leg was very short and when I pulled it out it automatically went back to the be very short. My mistake! So I unlocked the top plug, fully extended the leg and then re-tightened the plug. I did the same fore th…

Hello, afther my front wheel was going to high and to far my original Beta Handlebar need to be changed on the bike. I have a short upper body and long legs, 1m74cm tall. Whats your advise for a handlebar? Renthal Jitsie ....original BETA ... Greathings, Luc

Can you use any year CDI for your bike. If the one is newer I’ve replaced the original by my own errors and the replacement has also failed. It’s on a 300ss wondering if you can use any EVO CDI. Not understanding the whole purpose. Thanks to everyone who responds in a advance cheers.

Identify this aftermarket Hydraulic Clutch fitted to my Beta Zero ? Any guidance here appreciated I know literally nothing about 1990 vintage Trials Bikes I purchased what I believe to be a 1992 Beta Zero But it has this Hydraulic Clutch set up ? I have a number of questions like how do you bleed it ? It does not seem to have a bleed valve but I am sure I can research that if I first know what it is. I am sure this bike came with a Cable Clutch

Hello All, I am working on freshening up my 2020 Evo 300 4t for the coming season and I have two questions at this point. 1- I bought a TRP shock to and am wondering if it matters which way I orient it? It looks like shaft up gives easier access to adjusters, but print on the shock indicates shaft down. I searched the web and people seem to do both. 2- My bike tends to dribble gas out of the carb vent lines when I am riding rough terrain. I don't relish getting gas in the streams, etc. The float level is to spec, and it still happens. I remember running vent lines up and over the carb in the past, and I am wondering if this would help, although I imagine it might de…

Hi all found a good running tr34 picked it up yesterday the engine runs and starts very well which is a bonus but the cluch started to become abit random after about 20mins light slow rideing in tight flat Woods sometimes engaging far out (lever wise) and other times nearer the bar which is whare I like it.when I first took it out I could also seem to find a false neutral if you keep pushing down past first. But it's seems to have stopped doing it now lol which is weard.any info would be much appreciated and does anyone know what the best gearbox oil is for these engines. I'm thinking putoline light gear but any ideas from other owners. Cheers.

Does anyone turn off the fuel and let the engine cut out thus clearing the carb and fuel line after the last ride of the day? Could it be damaging? (Beta Evo 250)

Just wondered who makes the best fitting levers for the Evo Grimeca clutch and brake controls on a 2020 Evo 200? I’ve got a couple of sets of basic Apico dual purpose ones with the two sets of adjuster holes but they don’t have the same fit and feel as a genuine Beta one I have, a short type clutch lever from a Rev3. Unfortunately I only have one though and no brake side. And I prefer a matching pair! AS3 make some that look good or there’s the Apico Elite. Or does anyone make an OEM replica? Don’t really want to pay £30 odd quid each side for ones from Beta. Any suggestions?

Hi everyone. I have owned my Evo 250 4t from new, but it only has 19hrs on it. I have been told that it is nice a quiet in the past. However, I have always felt that it is a bit too tappety. I have removed the engine and checked the valves and following a few failed attempts the gaps are now definitely as per the manual. But still the rattling continues. can you please have a listen and advise what to check next.

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…
