first thread since MG so ...
Yesterday i was riding my QA out in the bush just cruising along enjoying life at 30k's and about a hour and a half of riding she started to smoke more than she normally would. I knew that the engine was due for a new piston and rings so i went to my local honda dealer to get one ordered. When i got there they told me they discontinued the piston for the QA's. So being a little dissapointed i went home and started to pull down the top end and have a little looksie. found out there was a broken ring (no surprise there).

So seeing as how i still had the old spare parts engine i thought well the compression was still good on it ill use that piston and rings see if it will run better. boy was i in for a surprise. the piston was covered in rusty mud and the rings were seized

i soaked the mucky piston and rings in 15/1 marine fuel over night and the rings freed up so i gave it a rub down removed the rings and the piston looks good as new but i will have to source a new set of rings for it.

the case with the mucky piston is the spare parts which is full of dirt and allsorts of nasties but the engine in the bike is clean i split the case last year and she was super clean:grinning-smiley-003
