Does anyone know if the Hyperpak from New Zealand will function on a SR that has a battery eliminator?

I'm not so sure. The one I received did not bring spark from the plug. The original CDI box does. I sent the Hyperpak back to New Zealand for a replacement and am awaiting it now.
My SR has a battery eliminator, hence my question.
Just looking for a definitive, proven result. Hoping that the Hyperpak does not know the difference between battery or no battery present.
If no one responds, I'll find out when they send me the replacement........

Hi,
I tried the Hyperpak from New Zealand on my 78 SR with a battery eliminator and could not get a spark. Hooked the battery back up, still no spark. I e-mailed them Nov 8 and still haven't heard from them. Seems I was burned by Hyperpak!
Hope you have better luck.

If you can wait until the new year I will have my own version of the Cdi box for sale.  |

I e-mailed them Nov 8 and still haven't heard from them. Seems I was burned by Hyperpak! Hope you have better luck. Dang! I sent mine back to Wayne Gum after an eMail explanation and he returned the message with an apology. Hopefully he'll stand behind his product, and send me another. Many others have had such success with the unit. I figured mine was one in a thousand. Guess we were unfortunate........ I'll hound him for awhile on the issue if I don't hear from him soon. Maybe I can find an advocate Kiwi to assist in either a replacement or $145.00 remuneration. EBay and PayPal might help out. |

The hyperpack unit has a wire going to the battery? If so it probably needs a battery to kick start.
If I recall, Aero's unit is a plug in for a stock unit just 30 years newer in design.
I finally broke down after 34 years away from electronics and bought myself an oscilloscope. For problems that need more than a digital multimeter to diagnose.

The hyperpak does not need a battery.
My box is improved, the diagram of the one on here is wrong, only in detail, but an important detail. If you build it it will work, but the advance will be erractic.

The hyperpak does not need a battery. I thought not, but wanted another opinion or at least a "real world" experience. Thanks for the posting. Hopefully, I'll get either another unit or my money back from Wayne. From most accounts, he's a stand-up guy, and should take care of the issue, one way or another. I do want to give him the benefit of the doubt. Shipping does take time. I took it to the post office on the 28th of November, so want to be reasonable on the time issue before I start squealing too loudly. Any of you Kiwi SR mates in Auckland? His address is: ERD, 102a Totara Road, Whenuapai, Auckland, NZ. Phone is + 64 9 4161658 If any of you have met him, please go to bat for me! Paul in Tulsa, OK USA 1980 SR 500G stock connections.  |

If you can wait until the new year I will have my own version of the Cdi box for sale. What's the ballpark price? Not looking at the moment, but nice to know for myself in future and for others... |

I run a modified alternator stator thingy, no charge coils etc, only ignition coils and no battery. I have had a hyperpak cdi box for about 18 months now and it has never missed a beat. It has a better advance curve than the stocker as well, and the motor does not brickwall anymore since it was fitted. Great product. Cheers Franky b.

For us in the US of A they are 150 dollars plus the shipping. Wayne sells them through eBay, and I'd expect he has them on your eBay site. He also has a website that you can visit. www.erd.co.nzI did hear from him today, he is checking the status of my unit and will reply tomorrow....so I suppose he received it. |

Knowing how it works I'd question if the advance curve is any better, that's sort of fixed by the generator. You can faff with it a little, but not much. In theory you can, but in practise all that happens is you loose the timing signal and it reverts back to the retarded timing. Have you actually put a timing light on the bike and plotted the curve? It will follow the standard curve. It has to as it an anologue system that works on the rate of change theory, the faster you spin the engine the quicker the voltage in the pulse coil rises to the level that discharges the capacitor, which gives your advance curve. So if you like you can say the pulse coil controls the advance. You can filter the signal one way or the other, but you can't alter it much. What you can improve is output, the orginal Yamaha box is a bit crude in this area, it just uses a diode, you can control the capacitor better to give it a sharper rate of change, thus making the spark a bit hotter. |
