I experienced kickback today several times, I always use the key to shut machine down. I experienced it when starting machine in gear using the brake lever. I started putting in neutral and started it several times with no kickback. Coincendence probably, may take new CDI out until someone sorts out. I know it is not battery or loose cables, will try a lower idle tomorrow.

 

I've been following this thread with keen interest. I have a CDI ordered but it won't ship till June. I'd like to suggest that one of you gurus check the timing with a timing light. My guess is that it is being advanced beyond 5 deg by the CDI during crank and at idle. That would explain the fast idle that all have experienced...and also the kickback problem.

 

Humm > So far, no kickbacks on my 04' P700. Probably 30 starts since Dyna CDI install.

I do however keep the battery on trickle charge when I'm not riding - Just an old habit I developed years ago. Seems to help wet cells last longer...

Wish I could remember for sure, but I'm (almost) positive I had to reduce idle after the cdi. Problem is, I also adjusted air/fuel screws due to cdi.

 

NYROC

my idle was high with the cdi. i turned it down the same day.

i really didnt notice any kick back though. i will see this weekend.

Scott, why wouldn't the stock CDI get kickback, if in fact the voltage was the problem?

Does your CDI require more volts than the stock one?

 

Nope. My machine at a 1200 RPM idle will immediately jump to 1350-1400RPM's when I turn on the module. (I have a switch on the bars). I've seen 2 others do the same thing; theirs had no tach, but you could hear the idle speed increase with the module. This was with either a Freedom or reds650 module, both had the same effect.
One more point - I'm running a 6 degree key which puts me one degree above the Dyna CDI at an idle or at maximum advance; no hint of a kickback.

 

No Problems with mine, at all. However, I am very curious that almost everyone is experiencing easier starting(when they aren't kicking back), and it idles higher with the Dyna. There is 1 and only 1 explanation for this, THE TIMING IS DIFFERENT FROM THE STOCK TIMING, AT IDLE. Scott keeps saying that their timing is the same as stock, at idle. I have very little experience in electronics, but common sense says that there HAS to be a difference at idle speeds. Please correct me, if I'm not seeing this right.

 

CF&W
Excellent point!!!

 

My idle increased approx 100-150 with the new CDI, just as it did with the test CDI that nyroc got from Sgtrock. I started the P650 10 times, tonight with and without using the kill switch and got no kickback this time. Like I told Scott on the phone, I will ride it next weekend and see how it does. If the performance is exceptional I will accept the kickback, if the performance is the same as stock or just marginal then I will send it back for testing.

 

You WILL have a performance increase! I can wheelie again in high gear, which I couldn't do after the cam redegree.[img]i/expressions/face-icon-small-happy.gif[/img]
