Question about Honda CB 750F2 Seven Fifty Motorcycles
Yes, you need to check the points and condenser. If you have no spark an the plug this is the first part to check.
The points have a cam follower (see picture point D), this follower rides an a shaft (E) that should have flat and hi spots to open / close the points. This picture is of a single point system, but will show what parts are what. The plate moves a very small amount (C), which changes the point gap, (which also will change timing) it is not easy to see how much effect there is until it is running and you adjust the points and using a timing light. Be sure the pints contacts are clean, if the condenser and points are old you may want to replace them. Rotate the engine until your points are at max opening. Adjust the points to the desired setting, Check a manual for the gap or start with .015 feeler gage. Secure the plate and all wiring. Test for voltage with the key switch on, using a 12vdc test light, the clamp end of the light grounded to the engine block. Touch the tip to the points top contact (B) it should be hot 12 volts DC, all the way back to the Negative side of the coil (A). Now as you turn the engine slowly, the points will close and the tip will touch and the light will go out, keep turning and the light will come back on. Look for your timing marks, thru the timing window there in the point plate. Turn the engine until the light comes on, adjust the plate to move the timing to align the timing with the light just coming on. This will get you in the ball park to start her up and adjust the timing with a timing light. Hope this helps Fix Ya up.
