Following on from my thread thought i'd introduce myself officially as i will be sticking around the forum, top blokes on here helping out a newbie with 1 post. Was expecting flaming but got a nice welcome and lots of advice ! I'm Craig from Clacton in Essex. Ride a ZZR 400 that will be getting a 600 engine dropped in it in a few weeks. Just learning all the mechanical bits and bobs, never really done much will do my best to help out where i can.

Before i got a chance to try any suggested methods, a 15 year old lad on my estate fixed the bike !! I recruited him over as i remember hearing he built mini motos and that for fun asked him to have a look. He turned the idle screw and now the bloody things running great, idle's fine !!! Always the simplest bloody thing!! I'd like to say a huge thank you to everyone anyway. Put about 20 man hours into this for it to be the idle screw, slightly annoyed but chuffed aswell !!

Cheers fr499y. Bit of an awkward spot. Will need to remove carbs now then. No idea how to do that either hohoho lol Research time.

Any trips on draining the float bowls? ( im assuming carbs need to be out of bike ) never done this before. Cheers

I'm confident to take the carbs apart strip and clean completely i just really dont want to go there. Do you think running the bike on choke without tank until it dies (empty carbs) and then fill them with prime for 5 minutes will be worth a try?

Just had the fuel tap off - filter is all intact. Fuel is running out of the engine and into the pipes fine just as it should Running bike with petrol cap open doesn't make a difference either !! Also i've gone over the vacuum hose with a magnifying glass and bright led. I can't imagine i missed anything and it's all in tact. I ran the engine without a tank on it until it sputtered and died (obviously burn the last bit of fuel in the carbs) is there a chance i've dried the carbs out and it's left gunk in them causing blockages?

Hi thanks all. It's a D model (91) and yeh the pipes have to be on correct locations as they dont reach / fit on anything else. I really don't know where to start !!

Cheers Dave. Yeh that's where i was heading.. What are the steps to diagnosing this? The bike run lovely before i took the tank off !!! Cheers

youtu.be/K0PY0mYpSLQ Any ideas? Bike working fine prior to tank removal. All tubes on fine can't figure it out. Wont start without choke or big revs and will die without choke. Update: All pipes are not kinked or have any obstructions. Tried running with fuel cap open so rules breathers out?
