I am in the process of restoring a GPZ1100A1. The bike is now back together and running but I can't for the life of me figure out which way operates the choke as it appears to make no difference. Should the choke lever be level when running and up to start the bike?

its a fast idle not a choke. all the lever does is open the the throttle slightly. the engine temperature sensor + air temperature sensor control the amount of fuel it needs at all temperatures including cold starting. lever should be in up position for it to start from cold although i never used to use the fast idle as it was much easier to warm it up with the throttle until it would tick over on its own

Same goes for my Z1300 injection

My first fuel injection resto - and possibly my last at this rate. Done many a carb resto but fuel injection is another ball game altogether. Pipes everywhere and very little info available on the GPZ. For the first time, I wish I had taken phots of where things went as it would have been soooooo much easier. However, got her all back together and running but I just can't seem to be able to synchro the throttle boddies.

Can you just confirm that the fast idle lever should therefore be horizontal for normal running and up to start (if needed).

Cheers guys

Yes, That's correct.

i am sure there are some markings + an arrow on the side of the fast idle lever ?

Thanks very much. I was clearly trying to balance the throttle bodies with the fast idle on - no wonder the revs kept increasing. Feel a bit daft now - I can strip and rebuild the bike but I don't know the difference between a choke and fast idle lever!

at least its sorted now..........

What was the outcome ? DFi or carbs ???

DFI. Outcome - Throttle Bodies 3 and 4 balance nicely but 1 and 2 balance but then go out of balance when revved so I can't look to equal out each side using the centre adjustment. It would appear that I have a sticking No2 throttle body and despite several attempts to free it up, I reckon a replacement set is now required. Bit of a pain really but everything else is now spot on with the bike and at least I know it runs with no nasty engine noises (apart from the miss balance that is).

I still have the throttle bodies I gave you the flap from
If they are any good to you pay the postage and you can have them
they have been outside for a bit but think they should be ok with a good clean & lube Just pm me if you want them.

Definately want them Brian. PM sent
