z1000h

[ninjabob]

hi guys had my z1000h fired up today it running on 4 cylinders to but like a bag of shite wont run below 4 thousand rev and its backfiring like a banshi with a rocket up its chuff
any ideas brand new plugs dyna coils fitted to
im thinking the timing might be a tooth out
also its leaaking oil from the pressure switch ever seen that happen on a zed before

Have you tried a timing light to check the ignition timing is correct?

[ninjabob]

no not yet ralph only had it running for a few mins after work but im over the moon it does i did a quick compression check and they all around 130ish is this normal ?

Doesn't sound a million miles from perfik

Carbs need a good clean & setting up

[ninjabob]

have you not heard Piglet is now an expert on fuel injected system's that use carb's
stuck your size 9's in it this time Pigiron

Bob check the airflow meter is totally airtight
it will cause havoc with running if it ain't

Have you checked to see if the injectors are squirting equal amounts of fuel? Could be a partially blocked injector nozzle(s). I had a couple of gummed up nozzles when my H was off the road for quite a spell.

I cleared mine by running some carb cleaner through them off the bike - using a temporary reservoir source and 'rocking' the injectors with a 1.5 battery.

i finally got a bit more done on the H today its tickiing over now but very high and around 3 thou as tho its got an air leak it wont rev to much as it just dies when you open the throttle but it getting better each time found out why it was back firing i think the advance and retard was seized on the shaft and would not move at all
think the injectors may need a bit more work or replace them just got hold of a spare set
any ideas would be apprecated

Have you checked the wiring / sensors are working correctly.

Might be worth looking at the inline fuel filter too - could be a starvation issue. I remember these used to give up the ghost pretty suddenly on my H. One minute you're tootling along fine - next bluuuuurr. Stall.
