Hi all joined in june, only just completed my profile, recently passed my CBT after a long spell of the bike, over twenty years, just had to have a rd 125 dx lovely looking bike, plan was to get use to being on a bike again then take my exam and test before the end of the year. But the rd isn't running to great, dies after about 20 mins no revs and will not jump start, it has a new battery, coils tested ok, but could these fail when warm ? starts up from cold ok, any advice would be most greatfull

ok sorry, done that now in my profile, errrr carb balance info from Haynes manual, all efforts so far have failed, put a new battery on then took it out for a spin after 20 mins the bike just died on me no revs and would not start, not even a jump start, took the coils of and they tested ok, could the coils fail when warmed up ? it's driving me mad plus getting ear ache from my lady. any help would be greatfull----please

Please help the bike will start up ok but when running it's reluctant to go over 5000 revs (50mph max)it holds back, i've stripped the carbs all looks nice and clean and ok, i've balanced them the best i can. but i still get this problem, I've started the bike with the right carb only (disconnected the left ht lead) and set the carb to idle about 1.3, but when i try the left carb only it will not start. I started the bike with both carbs and removed the right ht lead, engine kept running so i set this to idle at 1.3 for the left. BUT One thing i notice when running with one carb is the right side i can rev quite well but the left side is holding back and will not rev past 4000, i take it the left is the problem area. Is this a carb issue only or could there be other things i need to check, any advice would be most appriciated. Thanks Dave
