GPZ900R
Any suggestions on how we can get our GPZ900R to start from cold. It starts first time on the button when it's warmed up, even when it's left for an hour or so, but when it's cold, it tries to start but just won't catch. Any throttle kills it dead. The choke is working properly, we have tried it in all sorts of positions 1/4,1/2, 3/4, no difference. The carbs are all balanced, new plugs, new cdi unit all new mains and needle jets and needles. Float positions checked. Goes like a rocket once it's started, no flat spots etc. Must be something simple, perhaps a GPZ900R owner has had similar problems. We hope to here from you all.

Yes it has got the 3 position fuel tap, we have tried it on all positions. We have also checked the vent in the filler cap.Samray wrote:Have you got the three position fuel tap? .. On, Reserve, and Prime?
Re: GPZ900R
We have been advised to do a compression check, this has revealed a serious loss of compression on the two outside cylinders. I think this might just be the problem. We will let you know in due coarse.bikeral64 wrote:Any suggestions on how we can get our GPZ900R to start from cold.
