Yz450f launch control

Ricky4071
Hi,

I have a 2020 450f. Every time I start the bike then go into 1st, 2nd or neutral the launch control light. Flashes. If I go into 3rd it turns off but then comes back on when I shift down into second.

Anyone experienced this before and have any ideas?

Thanks.

Hi all!
I am having the same issue, so would this be down to a faulty switch and not a problem with the bike!
Thanks

Hi
Switch was flashing saying it was in launch control and when shifted into third when riding, it would go off as it should!
I had a little cut in the rubber on the switch so I think water was getting in!
Replace switch and it worked fine
