I am interested in the airbox and airfilter configuration. KTM changed the airbox on later CV carb models.
Any chance you could photograph the airbox cover and explain what the dohicky is on the side of your airbox?
What carb is you machine set up with?
Thanks, Bill.
G'day Bill, Below is a pic of the airbox showing the valve thingy on the side, sorry i have no idea what it does, it's just an alloy plate with a hole behind it leading into the airbox, the plate is a bit flexible so may let air in at some point, maybe theres someone out there can help? Filter is just a normal foam one, the airbox itself is much larger than a normal 640's, also see the holes drilled at the back, they're normally covered by mesh as is the top but the material is unavailable. The carb is a Dellorto PHM 40

Hope that helps
Bill (the other one)
