Throttle body rebuild

Hi Phil

I'm somewhat late for a comment on this topic, but I found the link to this topc on the gernan red forum.

When I first serviced the TBs of my V11 which sucked a lot of air into the engine that shouldn't be, I was not successful. I used the Yamaha seal ring and the same steel bushes with teflon coating as were used by Guzzi. The new bushes did not alter the play of the throttle spindles. Neither the bushes nor the spindles showed any sign of wear. I assembles it and found the running behavior of the engine as worse than ever.

Two years later I made a new attempt on the subject and used bronze bushings that needed to be reworked with a reamer. This was the solutio - the spindle play was severely reduced and so the sealers could handle better the reduced air  sream through the bearig.
