on my way home bike bike lost all power,no revs at all,pulled to side of dual carriagway,tried to start it up nothing,all lights where working,ignition light on turned bike off then on again and the bike started,continued my journey home but bike had a serious lack of power especially when trying to accelerate,like the bike was missing,juddering,the bike is a yamaha ybr125, and sometimes the bike will rev up on its own when ticking over,could the carb be the problem a thanks in advance for any help.

did my mod1 practice yesterday,did mod test this morning,was shaking like a leaf first exercise,parked bike up between cones ready to push bike back into other bay,forgot to put it in neutral,mind went blank, after trying to push bike backwards and couldnt get it to move,the examiner told me to jump back on bike and put it in neutral.great start i thought,anyway got bike in other bay,took a few deep breaths,next the slalom,no problem now the figure of eight,i am sure i did that more than twice lol,anyway called me over,next was the slow ride now this was different,i was asked to slow ride the bike,you do a slight turn then straighten up to park in the cones,examiner does not walk with you,u turn was dreading this,but went fine,sighting lap was a little slow,so on the emergency stop went faster,58km controlled stop a bit to far travel but he said it was fine,now the swerve avoidance,first run was only 45km,so asked to do it again,so off round again and just went for it,the swerve aint really a swerve,anyway stopped bike in cones,examiner told me to make my way to the gates,remembering life savers,parked bike up,into office,passed with 3 minors,49km on avoidance,bit to fast on slow ride,and taking a bit longer to stop on emergency stop.all in all well pleased.now on to mod2

i am in the same situation,but decided to have lessons when i have the time as my job hgv driver takes up most of my time.so my approach is a few more lessons,then go for mod1,then i still have plenty of time to get mod2 done before my (theory and hazard tests which i passed last month) and mod1 if i pass expire.plus still able to ride my ybr 125 to work and back so gaining riding experience all the time.if it takes me 12 months to pass my bike test so be it,just do lessons when you can afford them,no need to rush you will get there in the end
