Also you can easily modify the bracket tab thing to manually function by cutting half the tab arm thing off

I've had this issue since new, intake/exhaust/PC V and a tune didn't even fix it. :|

My 2017 does this too. Pisses me off. My girlfriends Grom fires up in half a crank, the Z takes several seconds.

is your sidestand down? My last one would do that even in neutral

 

[MrEvilpirate]

Yeah, I usually start it one the stand and let it warm up. Can't imagine why being on the sidestand would create a "slow start" condition, if anything I would think "no start", but I'll give it a try after work today.

I wonder if the timing changes with the new ECU are responsible.

Does your starter make a funny noise??? my guess is your starter is one of the ones with a bad bearing like mine and quite a few other people on here. Causes hard starting and starter noise. Had it replaced and it is better than new

can you describe your noises on cold crank?

mine:

Mine was very hard to start when it was super cold. I live in Iowa and I ride my Z to work every day as long as the roads are not covered in snow. I put a new battery on mine (2018 with 5000 miles and factory battery) and now it starts easily. even in the coldest weather it turns over quite a few times but it starts. Everything I've read says the NGK iridium spark plug makes it start much faster. Especially after doing intake and exhaust mod. Just be careful not to strip the threads when changing spark plug like I did.

did you go factory 50 CA size and model battery? seems it is all will fit.

Yes. I just went to wal mart and got whatever battery they had on the shelf. I think it's a duralast cost me $45

I pulled the tip over sensor apart and removed the guts of it.
No more starting issues 👍
