  1. Hi there. I just couldn't adjust the tickover of my carb. Realised the old plastic tick over screw was seized solid. Is this s common fault. Looking at how little used the bike is I reckon the carb gas never been removed before I took oenership. Removed carb and tried to screw it out but the plastic piece just sheared off. I carefully drilled it out then ran a tap (or is it a dye) down it to clear the thread. I was going to replace it anyway with a dab products tick over screw. It threads in perfectly but the thread doesn't seem tight. I'm hoping I haven't damaged the delicate M5 thread but I was careful. I'm guessing i need to refit the spring to give it some tension. Is this right ? I'm surprised there is no o ring. The dab products screw came with no spring. Does the thread give it it's air tightness ? Also the air screw had no o ring either. Is this normal ?
  2. Thanks for the info. Will try that
  3. My new to me beta 125 boggs like crazy on start up. It acts like the engine is not warmed up despite it running / idling for 5 mins. It revs fine stationary then when you try and ride off it boggs. It nearly dies it boggs so much. This goes on for another 5 minutes then it just clears and runs perfectly for the rest of the session. This happens every time I have ridden it. Air screw is 2.5 turns out. I notice on a cold start up, having the choke clicked on makes it rev far too high for a cold engine and I have to feather the choke without clicking it fully on to get it to run for the first minute. Then it idles ok. I have cleaned out the bowl and lower section of the carb with compressed air a few weeks ago. Any ideas ? Is the choke adjustable or should I adjust the air screw ? Fuel cap pipe is not blocked.
  4. Wheel building is a black art and few can do it properly. Measurements should have been taken before old spokes removed to ascertain position of wheel and bias to left and right. Your wheel builder will be able to pull it back quite easily as the spokes are nice and new thus bringing it more midline to the desired position. The same thing happened to me when restoring a Montesa. Mine was 5mm out. I had to return wheel to builder. It is a quick fix for someone who knows what they are doing. Hope you get it sorted.
  5. I had a look on the bike and I could feed the pipe inside the frame for s bit more protection. However I would have to shorten it quite a bit as the void doesn't go all the way up to the fuel cap. Shortening this shouldn't affect carburetion should it ?
  6. Many thanks for your detailed response. Very helpful. I will have a look on my bike later and see if I can route it through the frame. Otherwise I will get a petrol cap vent. Gaz
  7. On my beta evo 125 2012 one of my carb breather pipes goes vertically upwards and terminates near the fuel cap under a plastic shroud which houses electrics and the throttle cable. Should this be going in this direction or should it terminate near the swingarm like the other carb pipes. Or is this a breather pipe a d the others are overflow pipes. With the pipe running down to the carb it just seems like water could be drawn in when I wash it. Any ideas ? I've just had to strip the carb after washing the bike for the first time. Bike is new to me.
  8. Just done that. Put compressed air through it. No obvious muck in the bowl but it is now running really well. I'm convinced it was my over zealous jet washing that caused it as it ran great until I washed it. I notice one of the pink breather pipes nearest the choke runs vertically upwards and follows the direction of the throttle cable towards and terminating by the fuel cap under a plastic cover. Is this the normal route if such a pipe or should it go the other way and terminate near the swing arm like all the others. It just seems vulnerable to water ingress.
  9. Just bought a 2012 125 beta evo. Took delivery of it yesterday. Fired it up in the garage and it ran sweetly. Was very pleased. Gave it a good wash yesterday to make it perfect. Tried starting it after wash and it just kept bogging when choke off. After a while it started to run ok. Thought it must have just been wet somewhere . Then today I fired it up again today. Same again. Starts with choke on but revs are very high with it on. With no choke it dies if you open throttle and just about idles with no throttle. Any ideas ? I've just put in new fuel and a new plug to rule them out. The original plug was very black. Am I going down the pulling carb apart route ? Also is the air screw that tiny flat head screw on the kickstart side?
  10. Thanks for the response. Think you've missed my point though. I'm not interested in a 2021 model. I was wondering if when the 2021 model hits the market if there will be a few left over new 2020 bikes at a reduced rate? Back in 2012 I bought a new 2011 beta evo when the 2012 came out. Got it for £4000 instead of £4600.
  11. Hi there. I'm coming back to trials after a 6 year break. Cannot believe the cost of used bikes now. What happened? I've had four stroke trials bikes before as well as two and am considering a new 2020 Montesa 260rt. Mainly due to the Honda 6.9% interest rate which would suit me. It's £5999. Dealer says he will throw in registration and road tax. Delivery will be £20. Couple of questions. 1. If I wait a few months will Montesa release a 2021 version of this and any left over new 2020 bikes drop in price? I think the Honda 6.9% offer ends in may. 2. Shall I try and strike a better deal? I'm not part exchanging anything. I stupidly gave away all my bits with the last bike I sold. Should no haggle for accessories? Any thoughts?
  12. Looks awesome. I cant even get my two year old son close to the balance bike I bought him let alone a motorbike. He just likes spinning the wheels instead. Maybe he'll be a mechanic !!!
  13. I'm no engineer but surely this gap will cause some degree of flexion and undue wear in the swingarm bearing on the sprocket side ?
