5000 - 7000 flat spot
« on: November 17, 2018, 04:04:24 PM »

Hello. On my 2011 efi when I am around 5-7k rpm the bike doesn't really move. You can full throttle and it is very slow. Get passed.7 and Bam it gets and 1-5k rpm is ok also.  Just a major flat spot at 5-7k any reason why this may be?

I saw the flat spot topic here - http://korider.com/index.php?topic=16600.0   but nothing for 2011 and says does not work on efi models.

Thanks

HelloBoostinu13:

My 2012 GT250 (naked) is experiencing the same problem as your bike.  Mine intermittently goes flat in the 5000 - 6000 rpm range.  Am reluctant to purchase a new CDI unit without confirming that is the problem and I do not know how to check my current CDI.

Have you solved your problem?  If so, how?

A 2012 bike is EFI. It would not have a CDI unit. The 'wire cut' thing is only for much older bikes.

If you have a flat spot with an EFI bike, it's probably an air issue. Have you checked the air filter recently?
