550 horn problem

<< < (3/3)

florence:
I think they are all fairly noisy, especially the clutch and primary chain.  If the tickover is too slow they get pretty lumpy and clattery.  Why on earth Mr Honda didn't put in a primary chain tensioner I do not understand.  Oh well, seems to work even if a bit noisily.

Yoshi823:
All of my 550s have been quiet, from the '75 F1 with 37,000 on the clock when it was stolen, to the '78 F2 with 49,000 showing when it was sold. If the tensioning of the cam chain is correct, the ignition timing is done properly, & the inlet manifold 'O' rings are sealing properly so that the air/fuel screws make a differance when adjusted, there should be no reason why the engine should be noisey. Careful balancing of the carbs should only be attempted once everything else is done.

mickwinf:
yes i will need to reset all the valve/ignition settings now it has been running,will hopefully quiet it down!
