reed stops

<< < (2/3) > >>

Japie:
I just bought a set of Boyesen power reeds for my son's KX60. The cage did not have any reed stops on when i bought the bike(second hand), so i figured Boyesens don't need any stoppers? I can not get the reeds to "seat" properly, meaning there is a gap between them and the cage. No amount of swopping and turning helps. Are they supposed to be slightly "concave/conveks" in profile when you buy them?

Hillclimb#42:
They should be sealed up tight. As far as I know, they need to resist free-flow or you will have a rich condition that is hard or impossible to tune out. i have seen reed petals with broken corners, that didn't look like they would change anything, since they were still sealed, but the bike ,a yz125, would bog right off of the idle, if you gassed it real hard. It would go "bah, ying." I like my Vforce. Expensive, unless you compare to buying something else and that cheaper deal doesn't work right.

kaw rider:
try flipping the pedal and see if the helps the gap problem

Friar-Tuck:
No, to the question on any air gap on the reeds.  they should seat against the cage or "Frame".
