ok im working on an 07 ZZR600. the shift drum broke and i split the case and replaced it. since i was that far in i reseated the valves too. when I put the motor back together i set the timing and checked and recheck to make sure it was right. i checked it 4 times. 3 times on the bench and once more in the frame. im getting fual, spark, and air but she still wont fire up. i crank it and hit the gas and it sounds like it wants to sart but wont. if i dont hit the gas it doesnt sound like it wants to start. when i prime it (by turning the gas a few times) blue flame shoots out the carbs? any and all help would really help. ive been working on this or almost a month.

 

Welcome to KF. Are you sure then that you did not get the valves too tight? Do a compression test and record the numbers. Good luck

 

sounds like something is not hooked up ...fuel pump...fuel lines???

 

True, put a pressure gauge and verify pump pressure and check flow.

 

it was to tight so I fixed that. the fuel pump turns on. but still not starting. it sounds like it really wants to but just wont.

 

all the lines are clean and clear non of them are pinched that i see

 

are you ready for your 3rd diagnosis ? your timing is off.did you mess with your timing plate at all ?

 

We need some numbers now unko. Otherwise we will call this another guessing game thread in which nothing will be resolved. Get the manual and get some numbers to work off of. You know that we are all here to try and help. Guessing is just not cutting it. Please help us out like we are trying to give you the best information that we can. Do I sound abit Frustrated? lol
