F2 running problem

<< < (2/3) > >>

SteveD CB500K0:
Looks like you have a 550 tach. Here's a picture of my 550K3:


If the guys in the US are correct and the ratios are indeed:
CB550 20:3
CB750 4:1

Then your rev counter is reading a factor of 1.67 to high.

750 guys. Is 4800rpm at 70mph more reasonable?

If so, looks like a quest for a replacement (750) tach.

Carbs may have been cleaned but were the press in pilot jets removed?

Here is a photo of uk spec F2 clocks.
Your rev is not a F2 rev counter.

brianm:
Thanks, I will try and source a replacement tacho.

F2 Paul 876:
Here are the part numbers for you, its number 13 on the list.
