Yippie...My new cdi finally arrived today! When I got home from work this evening, I spent 2 minutes installing the new Dyna cdi on my P650 and then about 30 minutes or so testing it out before I had to return home for dinner. My initial impressions are as follows...

**3 BIGGEST DIFFERENCES I NOTICED TONITE**
1) WITH STOCK CDI it accelerated hard from 0 to 50 mph and then slowly accelerated from 50 to top-speed...WITH DYNA CDI it accelerates hard from 0 to top-speed (this is probably caused by the fact that Dyna cdi has NO retarded timing at top-rpms whereas the stock cdi retards the timing from 6500 rpms until redline);

2) TOP SPEED INCREASED BY 3 MPH WITH DYNA CDI (HIGH RANGE -- old top speed was 63 on flat ground and new top speed is 66 mph...LO RANGE -- old top speed was 44 on flat ground and new top speed is 47); and

3) My SEAT OF THE PANTS impression is that the Dyna cdi pulls stronger thru-out the mid range as compared to the stock cdi with DG holeshot (this is probably b/c max ignition timing is 5 degrees more with Dyna cdi).


**3 MINOR DIFFERENCES I NOTICED TONITE**
1) With Dyna cdi, the engine starts a little easier and idles a little higher than it did with stock cdi;

2) With Dyna cdi, the engine revs and sounds much smoother than it did with stock cdi...now there's no more bogging down sound when I hit WOT at low speeds when under load...sounds smoother now, especially when accelerating hard or when letting off throttle after a WOT run; and

3) With Dyna cdi, the engine seems to run a little cooler b/c I noticed the fan came on and only ran 30 sec. or so tonite after several back to back runs at 60 plus mph...whereas it usually kicks on and stays on much longer (for at least a few minutes).

**1 THING IS THE SAME AS STOCK CDI WITH DG HOLESHOT**
Another thing I noticed tonite was that my take-offs at WOT from a dead stop appears to be quite similar to the take-offs with stock cdi and DG Holeshot Module installed...In both situations, it consistently pulls wheelies very easily when taking off from a dead stop on pavement in either high range or low range.

Thats all I can report tonite...will do some timed runs tomorrow morning to measure difference in acceleration at 100' and 300' and then I'll report back. So far, I think I got my money's worth!

Which power curve did you use? It sounds to me like either 2 or 4, but on the website there are 4 different power curves and I wondered which one you were using.

 

Redgoblin,
Generally speaking, Dyna makes 2 kinds of cdi's...one is programmable and the other is not. The new Dyna cdi for the P650/P700 is NOT programmable so there is no power curve to choose from.

Just wondering, does the the Dyna cdi have an effect on the Kawasaki new bike warranty? I have a 3 year warranty with my o4 P700.

 

Not sure if it voids the warranty or not...but the best thing to do is simply install the stock cdi before you take it into the dealership to have any repairs or maintenance done. That way, there won't be any questions raised about it.

Thank you, now that is thinking ahead. Thank you for the good advice

Great info, now we need some tests runs with the cdi and a DG3/offset key combo.
