Title says it all, buddy is trying to local source a 10mm x ~105 mm engine bolt because the original aluminum one broke. Note to owners, don't over-tighten & might want to stock a spare something that works, seems the alloy bolt has a prior history of failure.

Is the flywheel securing nut Lh tbread? also, what about the threads on the flywheel itself where you screw in the puller… M32x1.5 I think?.. left or Rh thread? (cant see why it should be Lh but you never know?!)

Starting to strip my 2013 4t.. gearbox issues…. Can’t get enough slack on the chain to remove the cam shaft! tensioner is removed… manual says just to lift the chain off the gears and remove the cam but I can’t get enough slack. also the retaining ring for the cam shaft bearing is slightly too long to come free of the retaining groove to allow the bearing to slide off?!… Ive even tried removing the guides from the block but they won’t come out either at this stage I must be missing something in the manual but I can’t think what?

Starting to strip my 2013 4t.. gearbox issues…. Cant select gears, lat month I snapped the quadrant off the gear change shaft.. I repaired that and made a new pivot slide for the change fork as it was really sloppy… gear change was brilliant after… until I dropped the bike onto rocks now I can sometimes select either 1st or 2nd but nothing else… the gear shift drum behind the clutch basket isn’t moving so something is amiss in the gearbox.. started stripping the engine today and first snag is I can’t pull the plastic water pump impellor off its shaft!.. circlip is removed, there’s a little bit of movement between the shaft and the plastic impeller but it’s stuck fast!… tr…

Has anyone done this? Could the Evo 4T share cases with any other Beta models so it may be possible with factory parts?

Would like to hear from anyone who has a Factory 200 regarding if it’s hard to kick start. The 2024 200 Compression Ratio is 11.8.1. My current Beta 250 Factory has a ratio 9.1.

Hey there, trying to figure out what bike this is to start bringing it back to life, any advice?

Hi all. Back on a Beta after a couple years on a TRS. Lots of things that I loved haven't changed, but things i didn't like also haven't changed - plastics. They still seem very rigid & brittle. Is anyone making aftermarket fenders that are more pliable yet? A number of searches have come up empty, just hoping I'm missing something.

Hello to all ,,a newbie to suspension setup Need some basic advice for suspension setup ,,from the shop front fork damping was fully wound out 32 clicks ,i wound all the way in then backed it out 10 clicks as a starting point ,opinions about this Front preload ,was all the way out ,wound it 7 full turns in then backed out 3 full turns, And havent touched the rear yet but what would be a good starting point Would appreciate any advice ,regards steve

Hey guys, has anyone had this problem too? The rear brake rubber keeps getting sliced. The first one was an original the other 2 I turned down on a lathe.any help would be appreciated. Thanks.

Did/does anybody raise the position of their shifter to avoid shifting into neutral?

My 2013 clutch has always felt a bit too soft.... there's no positive 'spring' at the bite point....we've got a 2014 4T as well and that's totally different.... almost too 'switch' like...not quite as bad as some Montesa 4RT but not far off... I've fitted new clutch springs, slave & master cylinder piston kits. The clutch pack is well within the limit. Its almost like it needs slightly stiffer springs... cant find any though... If I put a thin washer under the head of the bolts on the clutch pack would this make the clutch a bit stiffer and a bit more positive?

Can anyone tell me what the crankcases on an 08 Rev3 were made of please, I seem to recall they are magnesium? I'm rebuilding one and the cases have corroded badly and so I need to refinish them. Thanks in advance

Hi guys, hoping someone can advise.....2013 4t, gear lever shaft has lost its normal 'stops' both up & down the gears. I can still select gears but the lever & shaft continue to move in both directions. It doesnt stop in its usual 'detent' positions and wont return to its 'neutral' position after changing gear...Its internal so its an engine out job but can I get to the gear selector mechanism or the gearbox itself without dismantling the engine first?...any thoughts as to the problem?

Hi Can someone tell me how to remove the thermostatic fan switch on my 2013 beta Evo. It looks as if it justs pushes in and is held in by an O ring, but I cannot get the old one out. Thanks Stuart

I do apologise if this has been discussed before, a quick search didn't bring up much. I just got back into trials after having a lot of fun last year on a TXT 250 and my boys 125. I have just picked up a 2000 Rev3 200. I know the USD forks aren't ideal but the soft, buttery power delivery swung the deal for me. I'm hoping it will help with the utter lack of talent I had finding traction on my old TXT. I am pondering swapping out the forks and yokes with a right way up set up from a later year, but in the short term, I'd very much like to service these tired USDs. I'm struggling to find much online regarding seal sizes and bushings. Even better would be videos…

Hello I am considering buying a Beta Evo 250 2016 model and was wondering if anyone could advise on what / if there are any known issues to look out for with this year of model? Thanks

my 2004 rm85 starts full throttle at start up and I put a brand new carb on it the throttle moves the needle is where its supported to be i don't know what to do.

Did anybody modify their Factory bike to make it less snappy, etc.
