Important notes about this kit:

• When jetting our carburetor kits, MAP Cycle uses only brand new, genuine Mikuni components.  We have been setting these kits up for decades and have provided jetting that works for the majority of bikes --  from stock to mildly modified engines.  Due to the nature of engines and the fuel requirements they have, we cannot guarantee perfect tuning for every individual motorcycle. Engine modifications, riding altitude, fuel type and ambient temperature all influence the fuel requirements which must be met for proper engine function. That's why we provide extra jetting so you can fine tune your bike to your particular needs.

•  In 1972, half way through the year there was a change with the cylinder head from screw-in to bolt-on manifolds. This kit is includes the bolt-on manifold that bolts directly to the head. If you have thread-in manifolds you will need the earlier kit. It is not uncommon for cylinder heads and engines to be mismatched on vintage bikes. If you have a question about your manifold, please take a picture and email it to us before purchasing the kit.

• Typically the 1972-1975 models bikes came from the factory with a dual cable throttle assembly (2 cables). However a 1-into-2 cable is available for single-throttle applications (see MAP0369/1)

• The factory air box must be removed or modified.
