Hi guys, I’ve been lurking in this forum for a while, recently bought my KZ550LTD which had been in storage for a vast number of years
anyway, a couple of months work got it back on the road but I do have a very slight issue.
my bike runs fine until the last 1/5 throttle, then it bogs down slightly
the plugs are showing a good burn.
one of the problems the bike had when I got it was a jammed ignition advance, which freed up quite easily…
but on investigation the main jets are 105’s instead of the 95’s I expected.
I wonder if the previous owner didn’t recognise the stuck advance and tried to compensate with a bigger main?
now…this is where it gets interesting.
The float bowl vent pipes are blocked off…and it runs beautifully like this.
if I unblock them it splutters a little and has no top end…
