Default v force reed block

v force reed block when looking through reed block when removed from bike I can see daylight, surely I should not be able to see anything or am I wrong, could this be causing my hanging tickover as ive been looking at the jetting thinking I had a problem there. many thanks.

Looks like the v-force is not that tight.
I changed the reeds on mine because I could se light as well and the result is that you can still see light.....
I talked to my gasgas dealer and he told
Me that the v-force is not as the boeysen where it is not possible to look through.

Default V force reed block

Was informed today that if you can see daylight when looking through inlet side of reed block then air can retirn into carb and alter jetting, may also give you uneven tickover. So no daylight to be seen,Any other opinions has anybody checked theirs.

If you can see daylight, somethin' ain't right.

Reed valves should fully seat to prevent bleed back to the carb.

Do you mean you can see daylight between the petals and the cage, or that the petals appear to have lots of little pin pricks in them?

The petals should seat firmly along the edges of the cage. If they are chipped, freyed, or warped away they'll need replacing.

That's the reason why I changed back to the boyesen. No daylight here.

My 06 EC200 has what I understand to be boyesen reeds: yellow colour / 3 screw holes / 2 part reed with 2 holes for the mixture to pass through.

Can anyone confirm that the smaller part of the reed should seal completely to the 'base' larger part of the reed ?

I'm trying to trace the cause of it feeling too rich off tickover regardless of airscrew setting. I'm fairly sure fatigued reeds are the cause because the reed on the upper side of the block seals completely, but the lower reed stays 1mm + open.

Thanks Elvis, I wasn't 100% sure. New reeds on the way.
