we ran 87 through 92 octane. performance dropped as octane increased. Kickback stayed the same.

 

Thanks crazy for the reply & info!

 

Well, when I got home last night I bolted the silly thing on and the beast started right up. I didn't really have alot of time to test all the theories but I did race up and down the street a couple of times ( to my neighbors delight! LOL).The most important thing to me was the factory rev limiter being eliminated and the product seemed to be doing that. Regretably I put her back in the garage and will now have to wait for my traditional Sunday afternoon PLAYTIME to find out more. Dont worry Wingnut Ive got the stock DCI in the tool box LOL and THANK YOU for that advice. I do have a silly question though. What is up with all of the through bolts on the BOMB that require a wrench on the back side to remove. Is this common on all quads for vibration or something like that or just BOMBS.

 

w1ngnut,

First I would like to assure you that my initial statement after yours was not intended to be directed toward you otherwise I would have quoted you statement. I was anticipating responses from a handful of others who are very vocal about the Procomm CDI in a negative way. However there are literally thousands who have them and never had a problem who are not so vocal. I grant you there are people here such as yourself who have had the misfortune of damage that is apparently caused by the CDI but not all of us on this site can afford a $400.00 CDI, some of us have to resort to the less expensive route as we continue to learn and build our bikes slowly...[img]i/expressions/face-icon-small-blush.gif[/img]

I tend to think that the powers at Procomm would quickly redesign their CDI if the general public was experiencing damage attributed to their product otherwise they would quickly go out of business...[img]i/expressions/face-icon-small-confused.gif[/img]

I'm sure there are several people who have been reading these posts who are waiting to see what DSADDICTED and I experience with his Procomm and my Big Gun CDI and that's a good thing. Like I said in one of my previous posts" If I find that I start getting the kickback that others have experienced I will be the first to blow the horn on Big Gun"..[img]i/expressions/face-icon-small-disgusted.gif[/img]

Again w1ngnut I was not questioning your intension's specifically and I apologize if I made you feel that way. I will not discuss this issue again until I have ran my bike with the Big Gun CDI and the MrHP piston and cams, which should be before the July 4th.

 

Scoundrel here is some first hand experience for ya!

Good information for those running PROCOM's, or thinking of buying.

I have experienced the much talked about "kick-back" problem with my Procom CDI. I bought it through an e-bay auction from PROCOM about 6 months ago. Last month I sent the unit back to PROCOM with a letter outlining the problems I was having and they sent me a new one, no response to the letter just a new CDI.

I called PROCOM after returning from vacation and recieving the new unit. I talked to Jennifer about getting my money back and my dis-satisfaction with their product.... she told me that "she had not heard of any problems with the PROCOM CDI causing kick back until "just this week" and that someone had just contacted her about the same problem. I find it very difficult to believe that they/she have not heard of this problem before now! W1ngnut who have you talked to there?

She went on to say that she was going to talk to the engineer who oversee's the production of the unit and have him do some testing on the units, "mabye they had a bad batch" or something. She also took my number and told me she would get back to me shortly. Have not heard from her since.

Some have said that they have great customer service. I guess if just mailing out another junk unit and ignoring the problem is great customer service then well......order one up!

I had intended to just sell the new replacement Procom CDI as new because I bought a Ron Woods unit after sending the original PROCOM back.
But, curiosity got the better of me and decided to bolt it on and see if the new one was any better......kickback within 3 starts.

These units are garbage in my "humble" opinion.
I had mine posted in the garage but I will not sell off my problem.
Either getting my money back from PROCOM or trashing it and chalking it up to a $100 lesson in not researching before buying, and count my blessings that I did not have to spend another $400 to fix my bike as others have done.

Nate,

I, as others appreciate your response. Like I said there are those who have had a bad experienced with Procomm and they are vocal. However there are those who have not experienced any negative results. I will join the club of nay sayers if I experience the same thing as you. If I do then I will have to stop riding and save for a Vortex.... [img]i/expressions/face-icon-small-blush.gif[/img]

 

You know its possible that the slight change in ignition timing between the various lables of Procom (Big Gun, Etc Etc) are enough to not have the "kick back" problem. I will be anxious to find out what Scoundrel experiences with his Big Gun unit - obviously he does not have a problem now. My experience is that the higher compression piston you go, the more the "kick back" is a problem. I know I'm grasping at sraws here, but it would be nice to nail down this problem.

Good post everyone!

 

I hope it goes well for you too!
We need a low cost alternative in the CDI market that works, the change in timing curve made a noticable improvement on my DS with the Procom, probably advanced just a little too much causing the kick back.
A little higher rev limiter is nice, no rev limiter with the Ron Woods could be bad especially when I decide to "FOG IT" [img]i/expressions/face-icon-small-happy.gif[/img]
Let us know.

 

Oregon,

You guys are makin me a little nervous!!!!!!!! Tell me if you would exactly what this kick back feels and sounds like so I will be fully aware of what to look for and remove the CDI prior to damage on my most valued possession. Riding is very valuable to me being that it is the only time during the week that I get to relax and unwind, so obviously I can't be tearin up the BEAST! Is the kickback as obvious as previously stated here or are there subtle hints that it is going to happen.

Thanks, Bryan OKC

 

Bryan,

Well im not very good at making sound affects, especially through the keyboard! LOL. Mine occured just off idle when the quad was sitting there and I was warming it up. I just slightly depressed the thumb throttle when the motor quit, abruptly and had a medium loud machine noise just after it quit - almost a grinding noise for a split second. That was with the RWR CDI that I had and I just put in my 14:1 piston. Now, before anybody gets thier fur ruffled, I dont think it was the CDI or the piston, but more of a combination of the two. All I know is that I switched over to the Vortex and the problem went away. I also realized that the idle was smoother with the switch. My conclusion at the time (which is pretty non-scientific and half-a$$ed) was that the ignition timing was too advanced at the low RPM and I got some pre-ignition at idle. This may be the same problem, or something entirely different. Since most of these boxes change ignition timing and rev limits, the only thing I can point to is the ignition timing. That can be either too advanced or too retarded, and it seems to me as it was too advanced - it was very similar to a ping - a big one!

Hope that helps - we are all still learning here - I know I never stop!
