  1. 10/42 works for me and best throttle i found for it is the amal 80/200. Good throttle and simple swap. You will notice two holes for cable on the carb end of the cable. If change to amal simply put the nipple in the opposite hole to standard then the cable fits perfectly. Same action as domino slow action throttle
  2. Relays are very poor for use on trials bike in mud and water, they are open to elements, actual metal contacts exposed. After packing up twice i removed it and sealed it with tape inside old section of inner tube,but periodically check/wd40 inside.
  3. Just checking, do you say a new relay doesnt help, if it doesn't click it's duff they are prone to getting damp inside.. good clean out with wd 40 works if you email oset direct they are very helpful with problems/advice
  4. The pre 2016 models were based on 125 but the new ones are based on the 250, using 250 crankcases and a flywheel made for the 200. Remember reading that on the beta site.
  5. I think the beta rev n go/ gas gas boy/ sherco semi auto 50s will be too small either now or very quickly. Rev 50 was bigger and had 4 speed manual. Ty 80 were/are great but again will be too small before long. Beta 80 is the most up to date, hydraulic clutch 6 speed modern suspension but small wheel ones are harder to find depending on budget, more of the big wheel but best to try for size first
  6. I remember watching Rob Shepherd back in, well a long time ago, on his Honda 4stroke. People flocked to see him at the likes of the Scott to see him find grip where others were stuck it just seemed to go anywhere. Love the grip of my beta 4t just chugs away,so smooth and progressive but if it does spin it's gone
  7. Same dilema, went for the beta 80. He had a beta 50 to play on a while ago, alongside oset. It had so little power compared to the oset, clutch very heavy as not hydraulic. Rev n go are good starters if dont want to start on osets but if you have had oset stick with it until ready for medium wheel 80. It's a big step at that age and bit of backward one until gets used to controlling clutch, starting it and choosing gears after the simplicity of the oset which is so easy to ride and throw about,but kids learn quick and worth it in the long run. I didn't consider the oset 24, after 2 years on oset time to move on. Most importantly, he agrees and will keep both until fully ready
  8. I've used magicals progressive springs in other bikes, much improved over old worn springs. They are available for ty, worth the money
  9. First saw wavy discs on mountain bikes. Loads of claims regarding better heat dissipation, better self cleaning. If there is a difference that is noticeable over standard round discs, not just on a theory sheet, it is more likely to be felt on bike subject to prolonged hard breaking. Maybe someone has done a proper side by side comparison
  10. I'm no electronics guru so you will probs get a better answer, i had issues with relays due to them not being a sealed unit. If its same as my sons, under mudguard his packed in twice due to muck getting in. Once totally dead, another time intermittent cutting out( could hear it click on then go off.) i regularly take it off and clean/wd40 it. My charger also packed up with the flashing error and it would keep clicking. New one ordered and fine. Not sure where your lipos from if poss problem with the protection circuit re overcharging etc?mine are in sealed pack and reading over 48v when charged. poss try borrow a charger?
  11. Water affects oset relay and throttle big time, they aren't sealed. Not a problem motor wise but the relay is open to elements and if it gets into throttle body can cause problems although wd40 can help( been there had both issues)
  12. Try wd 40 in the throttle body, problems i've had include damp in the main relay causing it to seize, but that's obvious because you hear it click if it's ok. Also had the same issue re wheel turning a few times then cutting out. Seems to have been damp inside as wd 40 cured it by squirting in gap at side of body, i always coverl it with a bag if washing bike and made a cover for it from old inner tube to keep most of the rain out. They don't like water!
  13. As above, just come along to a trial, say hello to the group with the kids you'll be very welcome kids entry normaly just a fiver and they get loads of time to ride round and practice too most weekends. For bigpie, look on acu.org website for list of local clubs with contact details, pick one, doesn't matter which and join, can do it online on acu site for some clubs. You get a unique ref number which you need to fill in an online trials licence form, on acu site in members area. Costs a tenner. There is a downloadable form you need to print and sign for kids.
  14. You probably already know but go to ACU.org and members area to fill in trials licence application, you need to join club first to get a ref number. Doesn't matter which so maybe join the nearest incase you want to go to meetings. As above most clubs have a conducted course now run seperate to main trial, there's always an easy course included for younger kids/new starters, It's a proper trial for the kids but they have great fun too.
  15. Had that once on a car, turned out to be ht lead, carbon breaking down when hot, car conked out. Soon as cool again off it went. Not sure if theres anything you havent replaced that could cause that
