Has anyone ever used or heard anything about these it’s for my gilera runner 2001 Should it be a straight swap with my old one ?
This is a derestricted manifold. There are much cheaper manifolds like this one on other sites. It will match up with stock pipe no problem. I paid 20 euros for mine. Well worth the money. Add .30mm Carbon Fiber reeds to the cage and you will notice a definite throttle response.
