I’ve had similar for two years, tennis elbow, pain down top of forearm when gripping. Rest from riding during lockdown hasn’t cured it. I might of had a dodgy physio but the exercises he suggested did nothing so I’m waiting for a different one.. I’ve recently tried using kinesiology tape (rock tape) and if applied as per the videos it does help symptoms. Injections may just mask the symptoms but not help to heal it, worth speaking to sports physio.

Interesting link here might be of some help http://www.tomdonneymotors.com/2019/06/11/2-stroke-detonation/

Haven’t used this part but I can vouch for the quality of their stuff and service. Wouldn’t hesitate to buy from them

Always found Oset customer services helpful if you don’t get an answer

If you start selling I’d be interested to try some on my beta 4t, will keep an eye out

Out of curiosity, what are they made of, are they a physical protection to the fork leg top only or incorporate a dirt cover for seal. Can’t quite tell on photo

As above, left side of headstock. It may of been painted over several times so it’s worth stripping paint off the area to check

C15T 101-301 were 1959 trials engines. Seems unusual a trial engine ended up as road bike, but who knows what has been done over the years. Do you have the frame number. It would be great if you could locate any paperwork or registration documents. Restoration depends on how much you can do yourself, how much time and interest you have, how much money you are prepared to spend and whether to restore as road bike or use engine as donor for a brand new pre65 trials bike.

Also don’t tighten the gap so it nips the feeler gauge, just touching so it will slide in/out ok, Too small as gap is as bad or worse

Piston rises to top of stroke on compression and exhaust stroke, with spark plug out you can feel the slight pressure on compression by putting thumb over the hole, then align the marks when you know it’s the compression stroke. haven’t adjusted mine so I’m not sure of the timing marks used on beta flywheel. Some decent videos on YouTube of how to do it . Has to be compression as that’s when the intake and exhaust valves are shut.

Did you set them while on top dead centre ensuring it was on the compression stroke.. must be on compression stroke

I bought one from eBay “Ryde small motorcycle cover.” Only £8, covered trials bike well and survived motorway journey from Kent to Northumberland in the rain. Not completely waterproof but kept all the road muck off

Also Villiers services are handy site for engine spares if needed

Shows up, barely, on this one

I got a set of tank stickers from vmccshop.net

Jitsie omnia pants, still stretchy and comfy but not skin tight spray on, I bought a size up from usual and they are loose enough

Try Richard Allen trials spares on Facebook

Everything Jonboy said is true, very friendly sport, lots of people take it up around this age. Details of local clubs are on acu.org in members area. You can join a club and get your licence online. One way to get a bit of practice would be to go to a trial and learn how to observe, then you can observe a few trials with your bike, have a bit of a ride round and practice off road while there. When ready find out which are the easier venues near you and enter, you can always skip anything to really don’t like until confidence builds. Best practice will be taking part, beauty of trials is we all fall off. People will just give you help and advice.

Agree re front sprocket as above, Bosi exhaust and it will sound superb

I’ve had 2 beta 4ts and never had any problems over and above the normal servicing. Only niggle I find is they don’t like stalling, so if it does when hot and won’t start after 2 kicks, pull the red hot start lever out to start it. Personal preference but I find the fast standard throttle too quick(maybe perfect for you) Amal 80/200 throttle makes big difference just put the nipple in the “spare” hole on carb end, it’s obvious when you look and it fits perfect. Other than that I love them, very different to 2 stroke

Changed my c15 to historic vehicle. No need for insurance as vehicle is SORN

If you can get/borrow a volt meter check the voltage of each of the batteries after charging. A charged 12v battery should read about 12.7v if it shows 12v it’s actually classed as discharged and that means dodgy battery. However sounds like your Oset charger itself may be dodgy, we went through two when had Osets over 4 years. As above charge each battery separately and check they are ok then replace charger.

Other brands are available!!

Jet is too except in certain area such as teeside Yorkshire the Humber and Scotland

Meant to say I put it in fuel for 2T and 4T bikes too. No issues if a bike stands unused either.
