OEM reed gap

[jumjum01]

Since my OEM reeds had big air gap (0.7mm) I was looking to change petals or buy new aftermarket reeds. I did some reading on forums on different reeds and performance. Not very easy due to so many different opinions and very little dyno proof. I desided to check out my oem reeds and quickly discovered the reason they had a big gap between the cage and petals. The aluminium area where the petals are screwed i place with 2 M3 bolts where lower than the rubber sealing surface, causing the petals to bend when torquing down the bolts. I made a spacer from some 0.1mm trim stock to go between the cage and petals and now they seal up just fine.
I found this stuffer to go into the reed cage. Has anyone tried them out? They are a relative cheap upgrade if they perform like the dyno suggests.

I have used many aftermarket reed valves. Hard to say what is best in my street applications. I'm pretty sure that TDR, who sells his own reeds, uses VFORCE in their race bikes. I have VFORCE 4 in my main rider and they work great. Consider a set of OEM Banshee reeds as an economical replacement if you are going to replace them. I know Evans Ward uses these and is satisfied with them on his street bike.

Those "stuffer" parts may be snake oil. I've never heard of them. Maybe Martin will pipe in here on the things.
