Hi all,

After recently aquiring a 1977 cb750f2 im over the moon with it, yes it has a few things i want to do to it but over all it starts on the button and idles once warm, however when riding it seems to take ages to gain decent speed both rev counter and speedo seem to climb slowly, im beginning to think it may be over geared, the bike rolls freely and brakes dont bind. Rear sprocket is 43 teeth not sure about front still need to remove the cover, speed wise in 5th gear its doing 60 at 4k, 75 at 5k and 90 at 6k is this right any advice will be greatly appreciated, thanks in advance

That looks about Ok.

The motor needs revving.

With the throttle wide open it just seems so slow to rev

Johnwebley:
If you want spirited riding. Keep the revs above 6k, and don't change till above 8k.


If it still feels sluggish. Check timing and mixture

Points gap in spec and timing spot on bike idles evenly with no issues through rev range so im guessing carburation is pretty good or am i expecting too much im not after masses of speed but it feels muted ii has a motad 4/1 plugs are new as are caps and air filter
