March 9, 201610 yr Hey guys I've got a beta Evo 4t 2014 it has a slightly loud ticking , seems worse when it's warm , I had a overheating problem few months ago and I'm thinking it could be damage caused , any advice would be good fellas , cheers ?
March 9, 201610 yr A ticking noise can sometimes be the exhaust to barrel joint starting to leak and 'pop'..... Try nipping it up, not too much, and see if it helps. Go for the simple things before you delve into the (expensive) things.....

Go for the simple things before you delve into the (expensive) things..... The exhaust is not bolted on these but held in with 2 springs. I would check tappets and camchain adjustment first and go from there.

March 11, 201610 yr Very likely to be the valves. Should not need it on a new bike BUT you said the bike got hot. Does the noise frequency increase as you rev the bike? Is it getting hard to start when it is warm? Edited March 11, 201610 yr by billyt
March 11, 201610 yr Author Yeah it is a nightmare when it's warm and not sure if it gets louder when I Rev it but I've noticed it louder when it's warmed up ?
March 11, 201610 yr I had the same issue with a Beta 300 4T. The valves needed adjusted. They where adjusted and the ticking, clicking noise went away. Edited March 11, 201610 yr by billyt
March 11, 201610 yr Author Not sure about the shims !! But thanks billyt I'll get them to look at it , was it expensive to do ?
March 11, 201610 yr No shims. Bucket and screw. First thing is to check the clearances. I have the technical manual for the Beta 4T on just the engine. I can send it to you if you like? E-mail me at: williamtraynor@hotmail.com Edited March 11, 201610 yr by billyt
