I have adapted an ignition control unit from a 1988-1994 ex250 to my 2008 Ninja. the stock ignition timing is [email protected] rpm. Now it has 42 [email protected] rpm. also the rev limiter is set to 15000 rpm. I dont need to rev that high . But hitting the limiter will runin a run at maxton. The bike seems to feel more powerfull at 9000 rpm . But I will have to test it some more

nice make sure you let us know how it all turns out.

 

[Beezeroni]

awesome. sounds good. what led you to doing this?

 

[spooph]

are you going to be advancing the cams any because of this? Or maybe switch over cams from the old ninja as well?

 

[Jester]

Do they make aftermarket ignition systems for the 250? I know you can get aftermarket ignition modules for most cars. Some can be adjusted via computer, too. You might want to look into whether or not such things ate made for the 250.

 

[Racer X]

No one makes anything . I have spent a year on the phone with MSD Haltech and modoc . I will have to have a custom system made for my race engine. The problem is the pick ups on a 250 will not produce a signal any aftermarket unit will reconise. Something to do with pulse width.

that sound great darkhorse, any pics of the old and new . better yet a video would be better

Pushing the boundaries once again, nice to see Darkhorse, you rock.

Do you think this mod would work with a slightly newer "older" model of the 250? Say an 07 ignition box?

 

[Racer X]

The wiring is different . It should work. the revlimiter for 07 is14500 rpm. The only ones that wont work is 1986-87 they use a dual pick up.

This s#$t rocks. I GOT to get to a dyno. The pull from 9000 rpm even with the 42 tooth rear sprocket I use at Maxton last week is terrific. I can't wait to see what the print out looks like.

 

[Felix]

Nice, stick it up once you get it!

Love the dyno curves!

any update with this?

 

[Racer X]

Well it just works great . I have 1500 miles on it so far. The rev limit is 15000 rpm . and the bike runs very well with a full Yoshi and K&N filters.

I am taking it to the track soon .
Plus as a side note . I don't have the problem with the igniter changing RPM when hot that so many 08 ninjas have had.

What mods did you have to do to get it to fit/work?

 

[Racer X]

I just got a wiring harness from a 88-94 ex 250 and an igniter. Then jumped the wires to for the stock one (after removing the stock ignighter). the colors are the same but one . and one wire is not used. But I cant recal which one . But there is nothing to it.

approximate cost on something like this?

 

[Racer X]

I got the parts from e bay. make sure the wiring harness and the ICU are the same years.

What is the benefit?

 

[Racer X]

7 deg ignition advance (42 deg instead of 35 deg )and 15000 rpm rev limit . The stock engine dose not make power over about 12000 but when racing the 13500 limit is to low.
