  1. I changed it due to poor compression and then realised the ring had snapped when I took the old piston out, the ring fell off the piston into my hand, and I'm not sure I ordered it from pedparts.com it said it was for any water-cooled aerox so I really do not know what else I can do ?
  2. That's a good suggestion thanks alot but I'm quite sure I did a good job of cleaning the 2 surfaces and the old gasket did come off in 1 piece, also there is fuel getting to the cylinder as after a few kicks there is fuel on the plug and I have a good spark it just won't go.

    Thanks alot, also now the bike won't start at all and every now and then it backfires ?
  4. Yes I have got the arrow pointing forwards at the exhaust port, I'm sure that's correct ? But now it will not fire at all and is unregularly backfiring ?
  5. Hi all, I have recently changed a piston on my yamaha aerox and now it will only start with the choke on and with full throttle but will only rev up to about 2000 rpm but as soon as you release the throttle it dies again, all jets are clear , float is ok, new spark plug, new air filter and a new ht cap. any suggestions please, thanks.

    Also I am having trouble with my aerox I have just changed the piston and now the bike will only start with full throttle and choke on but will only just about rev up to 2000 rpm and as soon as you let go of the throttle the engine dies straight away, any ideas, thanks.

    I have put the piston in the right way and fuel is getting to the carb and all jets are clear, float is fine, just had new spark plug, air filter and ht cap but still won't rev, it just about starts but only stays running with full throttle but even still with full throttle is revving out to about 2,500 rpm, thanks for the suggestions
