Have a 73 CL175.
Its been running well recently. When I started it up this morning it took about 9 kicks to get going, would start, idle fine but when I gave it gas and the RPMs got to around 3000+ the engine starts making sort of a clicking noise - not a backfire "pop" noise, but more of an internal clicking sound. sounds like its coming from the left side.
Haven't made any changes to it recently.
My thought is maybe a timing issue? which is messing up the sparking?
Any input as to where I could start first would be much appreciated.
as a note, the PO told me that the bike tends to go through plugs. I was having issues before (taking MANY kicks to start, left piston not firing, etc.) and replaced the plugs a month ago and it has been great since.
