I was wondering if someone could give me a step by step guide to changing a piston, rings and barrel on a aerox yq100 Y reg as i havnt done it before and i cant really afford someone else to do it. I had a compression test done it was reading 30psi max so i have purhased a new kit but it is a 55mm big bore kit (This was cheaper then a stanard kit). Any help would be great. Cheers

So after cleaning the carb, new ignition coil, new spark plug, overall check making sure the petrol is gettin threw n its sparkin i tryed compression but had no proper way of cheking it and a mate told me 2 put my finger in n if it blows my finga bak out its gd if not then theres no compression meaning new rings/piston? i was wunderin if thts true as it didnt blow my finga bak out lol Also how hard isit to change piston etc is there any components i need 2 keep in line like timing belts on a car?? Any help would be great Cheers

Hi all im new to this forum as today i purchased a 2001 yamaha aerox yq100 with a problem. First thing is the previous owner (My cousin) said he was riding to work and it jus cut out and wont start now, apperently a car mechanic had a look at it n said it mite be the ignition coils, i was wondering if this was usual on these kinda bikes??? Second 1 is i have no electrics any ideas what that could be?? Any help will be much appriciated Thanks
