52517or52510+4559 - This kit includes the normal orings, fibre washers etc PLUS the float needle.... This is everything soft that needs replacement inside your VHB carb. You will get either the #52517 or #52510 seal kit [they are identical according to Dellorto] + the #4559 float needle valve.
NEW: We also now have some CRANK TOP type VHB seal kits.. These were on some early MV Agusta 4 cylinder bikes.... If you order the crank top type you still get a float needle of course.
