Step by Step instructions for
Installing a Camshaft in your motorcycle

The items removed from the engine to gain access to the camshaft must now be replaced. The checklist of items to be replaced is:
bulletReplace the exhaust system.
bulletReplace the footpeg and rear brake pedal.
bulletReplace the engine oil and install a new filter.
bulletReplace the transmission oil.
bulletReplace spark plugs and plug wires.

Now is a good time to careful look over the work that has been done.

bulletLook for any other items that may have been disconnected or loosened.
bulletConnect the battery.
bulletTurn on the fuel
bulletCarefully check all your work one more time.


You may not believe it, but the engine can be fired at this point. Go through your normal cold start procedures. If you were careful, the engine should come to life with very little effort.

After the engine has started and still idling, carefully check for loose nuts, bolts, hoses and fluid leaks.

If everything still looks good, you are ready for a test ride. The first test ride should be used to make another check for loose and disconnected items, Unusual sounds should be investigated. When the bike is returned, check the bike again for loose nuts, bolts and hoses. If any fluid leaks were going to develop, you should find them after the test ride.

If everything is still fine, the engine is ready for a few more test miles. Once you are sure that the work was done properly, final tuning needs to be performed.

With a new camshaft in the engine, it is likely that the carburetor will need re-jetting,  the ignition timing be set and make modifications to exhaust system baffles. The best place to do the final tuning is on a Dynamometer. Head for you local dyno tuning center and see how much horsepower your new camshaft is producing
