Bike wont tick over when cold fz1 2007

[davey boy]

Any help would be apreciated off touring the outer hebridees in a few weeeks so want to get it sorted
I have fitted a fce and a power commander v and since then when i start the bike i have to hold the throttle open untill it warms up then it runs perfectly
Could it be the o2 optimiser
Any sugestions

I've got an FCE fitted & I also have a brand new PC5 which I haven't fitted yet.

thing is I already have an intermittent starting problem doh!....so it will be a little while before I go fitting anything else until I establish what is at fault.

Have you tried it with a different PC map to see if it is a dodgy map causing it or have you tried completely disconnecting the PC5?

When I fitted my FCE my tickover was affected, it would still tickover but had dropped to 950 revs and was lumpy. I adjusted it with the adjuster ( ! ) to 1050 revs and it was fine, I think manufacturers set it to 1100 / 1200.

& here's the adjuster.....turn with a screwdriver...jobs a good'n.


Good shout slappy.....i was panicking there thinking i might get more issues after fitting my PC5.


Let us knowhow you get on will ya Davey please.

Thanks for the reply lads just got back home so will try in the morning
I thought you could only ajust the tickover on bikes with carbs, you learn new things all the time:-)

The warmed engine temperature idle is best at 1250 - 1300. Any less & you risk temperamental starting & a lumpy tickover.
The enriched idle for cold starts should be 1500 - 2000.

Sorted thanks
That was an easy fix although I could only get it to about 1100 rpm on the tachometer and the adjuster was spongey didn't want to push it invade I snapped it I soaked it with wd40 but that's as far as I can get

Yeah, there does not seem to be very much adjustment, I had my laptop hooked up to the bike through the Juicebox as it shows engine revs a lot more accurately, I would assume that you could the same with a pc5 or pc3.

What Dekf says about the idle speed is more than likely right , he has a lot of experience in tuning the gen2 , but I just found my tickover was ok at 1050 revs and at 1100 or more the bike just sounded as the tickover was set too high.
