hi guys i have a problem with my yb100 not starting i have changed the ingtion coil and spark plug points n condeser but it still wont start i then thought it might be low compression but the compression is good i then checked the soures coil in the magneto and im only getting a reading of 0.2v iv cleaned the flywheel up and checked the connections and they all seem fine but now im at aloss for wot to do or check any ideas?

you changed the points Callum, check they are clear of ground the spring is clear and the insulators are present and correct...it's been a long long time since i had a bike with points

hi airhead iv checked the points n there all clear and the insulators are all there.

when you measured the voltage of 0.2v was your meter set to AC voltage setting?

hi no it was on dc but just tryed it on ac n im getting nothing

was it running before you changed the points and condensor?

no i changed them hoping that it would fix it because they looked worn

Has it ever run?

yh it was running till about a month ago it just cut out i was testing its new exhaust at the time

so you have no spark?

its late now will be back tomorrow

yh i have no spark kk

one last thing

with the points open what resistance do you get from the moving point connection to ground?

hi mate i tested the resistance today but i checked the connections again and found a lose wire so i put some more solder on it so it was a solid connection and it runs thank you for all your help. i also have another problem when i am indicating and press the brake my indicator goes out untill i release the brake any help would be great.

Could be anything from a past it's best battery to connections on the 23 year old loom to unclean earth points

I would go with earth points and battery first

and is the battery filled to the correct level with de-ionised water?

is it 6v or 12v by the way?

its a 6v system and its just had a brand new battery about a 2month ago coz it dint come with 1and filled to the correct level and iv cleaned all the earth points connections and switchs and its still the same

have a read of this Brendon, see if it helps
