Time moves forward and I see both companies seem to offer more/better products etc.
Am i right in thinking that the big difference is that HPI doesnt charge the battery and the VAPE PD does? (im talking the road not the race versions here)
Anyone care to comment on other differences?
Im thinking that with parts dwindling now that its going to be harder and harder to find usable nigh on 40 year old ignition parts that haven either died or been wrecked by a ham fisted owner, and that this is the kind of kit we will have to go for. hmm..

HPI charges the battery.
Well, at least the one we ran on our aircooled RD350 6hr endurance racer did.
Ran the lights plenty bright too.
No complaints at all.

Interesting Jim, thanks for that.
The HPI is quite a bit cheaper than the VAPE, I was just wondering how they stacked up against each other since we are going to have to learn to embrace the aftermarket going forwards.

We were very pleased with the HPI for our application. As stated, we initially bought it to power our low-budget, spare-parts AC RD350 racer. For that application, we basically ran the HPI setup alone, with no stock wiring loom. To be honest, it was a few years ago, and I don't remember if we were running a battery. Of course, no lights at that time. The bike always had plenty of juice, ran very strong, and started first kick every time (came in handy for the LeMans starts) After race day, this RD350 was relegated to street use. Not sure what other wiring was added, but I know it's now running with head and taillights, and still powered by the HPI. No turn indicators, horn, cooling fan or anything else. i  |

I've got a HPI unit to install on my RD400. Not had the time as yet to install it. Seems to work really well: www.2strokeworld.net/forum/index.php?topic=1139.15Light flywheel. Charges single phase, but easily converted to dual phase. All in that thread. |

I was just in contact with HPI regarding hpi.be/item.php?item=068K058-2CFThey replied to my email in 30 minutes! Outstanding. He reckons that TZR kit will fit my RD125LC engine, worth a shot for £175 inc vat. Especially if it replaces the stator and CDI. I've emailed him to ask if it runs the lighting circuit too. If it doesnt, what's the options there for a road bike? I'd need indicators, headlight, taillight etc. |

I got a reply. It won't run lighting. does that mean it won't charge the battery too? How would I go about getting the lighting to work?

www.hpi.be/item.php?item=210K072I was told this one instead, he said the only issue is that it's 60Watt 12Volt AC (Whatever that means...). I guess because it's for a single cylinder. Just curious how 'plug and play' it's going to be as I don't have a clue about electrics.

Just curious how 'plug and play' it's going to be as I don't have a clue about electrics. Sure. I guess they know. You can compare each item from the kits. I plan to run an LED headlight bulb, as per that thread I posted. So 60Watt should be fine. Have a look on there, I've not tried it as yet  |

60 watts equates to 5amps, which for a 125 will be more than enough to keep the battery topped up

to answer Jon's original post.
I have used/fitted both vape/PD and hpi systems.
The vape/PD system is a 150W charging system (approx 12 amps) so is well on top of the job. If for an LC then its a straight fit and they work very well. If its for a YPVS then you need to pair it with an ignitech or Zeel (of the correct model) - again they work very well
The HPI systems I've played with/used work within reason, the stock "fixed" curved system as fitted above to the 350 bike work fine, but I had allsorts of issues with the programmable version they do, in fact, I've yet to get it running correctly on a bike and I spent a lot of time speaking to "willy" at HPI about it
As metnioned the HPI systems come as a "race" version (non charging) and a "street kit", which will power lights, now the "power lights" doesn't mean it will charge a battery very well, you need to know the capacity/draw requirements of your bike
I've yet to do more testing of the HPI systems, but I've got my new home made unit to finish testing, which uses certain components of the HPI kit (e.g. flywheel) but mine will do 75 watts (approx 6 amps) and does charge a battery when the engine is above 2000 rpm (but not below that RPM)
