Spacer only without Oring.
This 10mm wide spacer has a 37mm x 40mm oval port matched bore for Kawasaki KLR 650. For use with Mikuni carburetors, up to 42mm internal bore size. The 6mm mounting holes are to spaced at 68mm apart (centre to centre) for alignment with the stock KLR rubber mounting flange and cylinder head stud holes. The spacer is made using 6061 grade Aluminum with a silver anodized coating.
This item is essential for clearance when wishing to fit a TM42-6 carburetor to 2008 and later Kawasaki KLX 650 models and will aid in other custom applications.
The assembly requires an O-ring (BS 132, available here) for sealing one side, with the groove set at 44.45 thru 51.24mm diameter (check that you have a good flat sealing surface at this diameter).
