What do you guys know about LED’s new HPI ignition? Pros? Cons? Set up? There is some info on Facebook about it. Says the cost is $330. Has a lighting coil. It says you have to set it up with a dial indicator. Not sure how involved that is. I’m still running a TRX ignition. A 330 on race gas can be a bit of a bastard to start. The cost of the CR ignitions are getting ridiculous and you still have to do something for lights. So what do you all think about it?
-
If you have to set it up with a dial indicator it sounds like a pvl ignition. I'm interested in knowing more!
-
I saw that post, it sounds like a great alternative to the cr ignition. I think my 01 crapped out, if that's the case ill Serously consider the hpi. I'll have Arlan dyno and set it up for me.
-
I don't see anything on his website
-
One guy on Facebook said it was difficult to set up.
-
I have the dial indicator to set it up. I will let you know how bad it is to setup. My friend has it ordered. It is what is going on the pilot motor. Darren what makes you think your cr is going out
-
What r the differences on the flywheels as far as size and weight. Looks small in the pics from LED.
-
Yes flywheel is small. CRish in size. These are very similar to PVL.
-
I think Arlen advised him to get the flywheel weight that is available for it
-
I know Arlan was pushing PVL ignitions when I talked to him awhile ago. I had a great condition OEM, so I didn't bother at the time.
The CR250 stuff is ridiculous. It would be awesome if there was another option
-
I just set this up on a pilot cylinder motor for my friend. Setup was easy with a dial indicator. One thing I don't like about it is. It doesn't have a groove for a Woodruff key. In theory it shouldn't matter. As long as it stays tight. But it did start easily with no kick back. We just did initial fire up for now. So ride test will come later. Plus maybe see how the lighting circuit works.
-
Nice. Thanks for the update.
-
No problem. So far seems like a decent setup. Didn't have any starting issues

Gene, how does it differ from a pvl besides lighting provision
-
It has a more traditional style flywheel. Instead of a internal rotor like pvl. I've never ran or setup a pvl.
-
If anyone needs help if you decide to try this. I'll help you anyway I can
-
i think have 2 pvl sitting in a box somewhere. i want to give those guys a try. next time i visit Arlan maybe ill pick up a HPI from him. id like to see the difference in them all. i currently run a CR.
-
I run cr. But will be interesting to see how this does.

i think the guy did something wrong
-
Ya I watched that also. We did not have any issues with it. It fired up the big pilot cylinder no problem. I think there was something wrong with his setup or got a bad part
-
I hope this works well. Ignition is one of the few things left for the 250r that we need a solution for.
Keep us updated if you will please.
-
That's the plan. See how well it holds up
-
Does your hpi have major kickback? Mine has terrible kickback if it's not at top dead center
-
I retarded my friends a little bit. So it wouldn't kick back so bad. You have to kick from tdc and don't half ass kick it.
-
Ok. The guy who did mine added a fly wheel weight to mine to help combat it he said. It was terrible to try an start. Going to take some practice to get used to.
-
If the kick starter is trying to blow off your foot when kick starting, something is drastically wrong. When this happens it is an indication that the ignition timing in the starting RPM range and or the moment of inertia of the crankshaft assembly is too small.
I have not used or tried to tune an engine with a HPI ignition. If it has a very small rotor, that could be part or all of the problem. If it has a rotor that has the same moment of inertia or higher than the OEM flywheel, the timing is at least 5 degrees too advanced in the starting RPM range.
If the HPI ignition is a programmable ignition I would retard the timing 5 deg in the 200 to 800 RPM range, leave the rest of the curve alone and see what happens. If the HPI has a universal timing curve similar to the basic very small rotor ignitions and other non programmable ignitions boxes, and the timing is adjusted by rotating the stator plate, rotor or reluctor plate, you may have a real dilemma. The choice is retarding the whole ignition curve so that the timing is correct at starting RPMs or correct at one RPM at the RPM of your choice.
My experience has not been good with ignitions timing curves that were not engineered for a particular engine package.

I have one on my 88 265r it revs good. I didn't know I had one when I bought a new quad. I had it for a year until I change out fuel petcock fuel lines. I like it very much

do you have kick back issuses PJ?
