hi all

i had a call today from the bike shop, and they said my piston return springs have snapped. just wandering if this is a common problem?

thanks for your help in advance.

hi m8, i take it ya mean on the carbs ye?


cant say ive ever had it on any bike or heard of anyone that has.

havent had my superfour long enought to know what common probs are yet (although reading forum i guess eletrical ones seem most common)

What did your bike go into te shop for in the first place? Just curious!

I don't know what a piston return spring could be... carbs sound most likely, I agree.

possibly means those little springs in the calipers that open them back out. "Anti-rattle shims"??

"Piston Return Spring" is a phrase used by sarchastic mechanics when taking the piss out of gullable trainees, like "left handed screwdriver" or "Glass hammer". Incedentaly, I was sent into town to obtain a glass hammer when I was an apprentice mechanic and actualy came back with one I got from a Thorntons shop.
