Grandsons beta 80 big wheel, not running like it should Cutting out and balking ,seems like a fuel/carb problem. Cleaned out the carb changed the plug but still no joy wondering if anybody has had similar problems or could offer any tips on getting it running right.Thanks in advance.

What I have found with little bikes is that the slow running jets and galley ways are so small that they easily get blocked and are very difficult to clear out.

Does the bike tick over okay? I have found if the bike will not tick over as normal then the carb needs cleaning and this can be after a fall with the bike etc. Once all cleaned the bikes run well again and only takes a few minutes to clean so just practice. Apart from that they are pretty much bomb proof and just techniques for starting if cold, if crashed or warm so I would start with the crab and ensure you clean all the jets out

On our bike I would say 100% the carb but just need to check air filter is clean, pipe work from air filter to to carb has no moisture and then fuel supply is clean. Jets are very small so ensure you can see through each one before putting carb back together. if you are a member of a club I am sure there will be somebody there who has experienced the joys of these bikes. They do work very well but need a little TLC

Was it running ok previously or has this just started. These bikes have a poor petrol tap. They can become very stiff to fully open, always a possibility that the tap isn’t functioning. Had to replace one on my sons for exactly this reason

You can get a lever style fuel tap from these guys https://www.trialsuk.co.uk/Beta-Fuel-Tap---EVO80REV80REV50---Lever-Style?search=fuel tap

More efficient & easier to use.
