Super Jet problems with electrics when installing epic (vid added)

[Penken]

so i have had som trouble with my ski this year and the past.
problems being that my ski doesnt hit as hard as it should.
riding it vs a friends ski.
same setup as me. i have mod b-pipe and he has a wammer carbon chamber b-pipe.
same head same domes same carbs same jets.
i have an epic and he has a msd enhancer.

so was frustrated that my ski ran so much worse than his. tried different jetting to no avail.
actually had a coffman sizzler on it first. so then this year i thought it was the pipe so i ordered a b-pipe. didnt realy feel any difference with the b-pipe.

so today i removed my epic ignition and installed a stock cdi and my ski ran great. it ran so much better.

does anyone know what it could be. i do not think that it´s the epic thats faulty.
more that there is something with my electrics that works with stock but not with the digital epic.

i have changed the pulser coil cause that was dead when i installed the epic. so i guess the other parts of the electrical system are hitting there maximum age.

i also have a jss ht coil on it. installed it when i installed the epic.

List your flywheel also so people will have a better idea

 

[Penken]

well it´s a stock one.
62t

 

[Magnum Mike]

are your epic settings stock or have any changes been made with the programming cable?

they are stock.
i connected it to a computer yesterday just to check that the timing curves was on it,



added a little vid to let you know how it rides.

that is with 72,5 pj 1 1/2 ls 135 main 95gr spring 1,5 ns
tried 2 sets of carbs

You running resistor plugs?
JSS uses MSD caps, non resistor.....

Just for the hell of it (and against MattE's advice) I tried running B8ES plugs (nonresistor plugs) on my COIL w/STOCK RESISTOR'd PLUG BOOTS. Ski barely ran, it was a mess. I switched back to BR8ES plugs and it ran perfect. I could not believe a stupid plug could make that much difference. Basically I am running a double resistor setup now. After my last test, I could see running MSD non resistor plugboots on a questionable coil could cause you issues even with resistor plugs. Just my guess, but something to think about.

Also I think Special_FX had an issue with his COIL leaking/causing too much interference to the EPIC. Your problem sounds like something along that line if you swap to a stock CDI and it runs fine.

The EPICS are awesome CDI's but they are sensetive to any interference.

EDIT:
My test was done with a 100% BRAND NEW OEM 62T electric system. New 62T stator, New stock FW, new OEM coil, NEW EPIC CDI, ect.

The epic enhancer seems to be sensitive to coil or stator issues. If you are using non resistor wiring or caps like in a Jss coil, consider at least using resistor plugs. The charge coil, that's the lower one on the stator should read over 500 ohm (brown to ground/earth on the stator). A good one I have measures 546 ohm at room temperature. However, as I found out you are not always home free with a good meter reading because if any of the windings of that charge coil have punched thru, you may not get the fault reading unless you energize that coil to heat it up. (about 50 volts for a couple of minutes should do it). I have several stators that work just fine with a stock cdi but will not work with an Epic.! I think the same goes for the coil , testing with an ohm meter is not always sufficient (oscilloscope to show firing curve needed)

i do run resistor plugs.
i´m going to try another ht coil. still an old one but different one. going to try it with resistor caps and resistor plugs se if that makes a difference.

measured the charge coil to 530ohms
and pulser coil to 15,8ohms

Also make sure your grounds from the motor to the battery and ebox to motor are perfect. For a test, you might want to try running a bypass ground right from the ebox to that battery to remove a groud issue as the cause. Especially if your stator is older.

 

[Penken]

i have measured all grounds.
gonna run the stock cdi probobly for the rest of the season as for now.

If you have another coil, that would be easy to try, otherwise try a stator. I realize those items are not as plentiful as they are in the US. I'm lucky to have hoarded these parts over the last years.

alright, here's the truth!! you're gonna end up changing all of your electrical components on the belief that is't your electrical system at fault but in the end, it's reallly the epic, and you ended up spending countless hours and $$ trying to figure that out!!

put an enhanser or OEM cdi back in and enjoy the rest of your short summer!

I have been going thru some issues with my Epic, mostly kicking back and back firing during starting, it would sometimes crank backwards. I changed coils, stators, switches, cables, batteries, flywheels, everything except the rectifier, no difference. (note all test parts were used). Chris at ATP even sent me a replacement Epic to try, same problem.

Then here is the kicker, we put my Epic in Andy's (WAB) ski and it works perfect. He rides a couple of weekends with it and no problems. I get it back, put it in my ski, it still has the same problem I had. I change the coil, put in resistor plugs and I even wrap the Epic in aluminum foil as a shield, no help, same problem. I pull it and put my MSD Enhancer back in and it runs great.

My buddy Jim Hill (thrillhill) burned up his MSD, so I lend him this Epic, it runs prefect and kicks a$$ in his ski.

I'm stumped, I'm running good electronic stuff, no junk. Could it be the rectifier, the only thing I haven't changed? I will try it if I can ever get my Epic back from Jim. I runs so good in his ski, I may have trouble getting it back!

trying to figure out the EPIC is like trying to figure out the bermuda triangle!! ...it must be some kind of vortex or magnetic field happening!

WTF are u guys doing to ur epics? I've owned two without any issues after the initial install. I even used some rugged looking electrical parts. My stator and ebox was from a 97rn on my first one. The hardest part for me was getting it programmed. After I got that done it's been easy.

what to do. to bad i cant try it in my friends ski he has a 61x ignition.

Du kan ju låna min gamla enhancer o pröva om den går nå bättre med den, blir det bättre med den så borde ju det va nått fel på epicen tyck man ju..

Yes, it would probably work better with that old enhancer. I did however have an enhancer recently that would only spark when you let off the green button as the engine was coasting to a stop. The 61X stator was at fault, even though it worked with a stock cdi.
