This swap always interested me for the power bump but I never found any good comparison info about it so I was skeptical that it was possible without major modification. I successfully completed the swap and it was very straight forward but you will need to some additional parts to do it.<\/p>\n

Here’s all the differences I found when swapping my CB550 cam for a CB650 cam. Follow the manual for the proper process of changing a cam.<\/p>\n

\"Cb550CamSwap-1\"<\/a><\/div>\n

Parts Needed:<\/strong>
\n79-82 CB650 cam
\n79-82 Tach drive
\nCB650 or CB750 Tachometer<\/p>\n

\"Cb550CamSwap-2\"<\/a><\/div>\n

The CB650 has a hy-vo cam chain so the cam sprocket will NOT work with the CB550’s normal cam chain. The CB550 cam sprocket and sprocket bolts fit on the 650 cam.
\nCB650 (left) \/ CB550 (right)<\/p>\n

\"Cb550CamSwap-4\"<\/a><\/div>\n
\"Cb550CamSwap-3\"<\/a><\/div>\n

The cam markings are very similiar between the two.
\nCB650 (left) \/ CB550 (right)<\/p>\n

\"Cb550CamSwap-6\"<\/a><\/div>\n

CB650 (top) \/ CB550 (bottom)<\/p>\n

\"Cb550CamSwap-5\"<\/a><\/div>\n

Notice the slighly different pitch for the tach drives.
\nCB650 (bottom) \/ CB550 (top)<\/p>\n

\"Cb550CamSwap-7\"<\/a><\/div>\n

Tach drive pitch is slightly different.

\"Cb550CamSwap-9\"<\/a><\/div>\n

Review:<\/strong>
\nI’ve been running the 650 cam for a few weeks now and have also changed from the air box to Uni pod filters. The power difference is not crazy but it is a nice even increase. The most noticable is on the top end, the bike wants to continue pulling strong 80-100mph. Previously it was a slower acceleration in that range.<\/p>\n","protected":false},"excerpt":{"rendered":"
