Anyone on these forums run the new motor city spark ignition yet? It's the one where the coil is powered by a battery. Ive heard good things about it on the Facebook group, but can't seem to find out if it has bad kick back like my hpi does. Thinking of selling mine and try this one if anyone has tried this yet and recommend it.

No...maybe confusing HPI units.

so to run one you will need a battery and then have to redo your stator to be able to charge the battery?yeah i'll stick with oem honda.
Yes; Hard to beat a CR250R IGN or stock Honda IGN on a 250R.

Seen two of the HPI's on customers TRX250R (310 & 370), both came in to BDT to cure the "Kick Back" and both customers complained the power curve was awful, basically a light switch. After installing CR250R IGN's at BDT; both customers loved the power and easy starts of the CR250R IGN.

One customers TRX250R (350) came in with a New MCSI (Motor City Spark IGN), he had 3 complaints; "hard to start", "easily flooded-then kick back", and "wouldn't get out of it's own way-no power on mid-top end"...we couldn't dial it in. Switch it over to a "Good" Stock Complete TRX250R 89 IGN...all 3 problems solved.

Conclusion; stick to Honda electronics, even if used, as long as they are "good" OEM IGN's, they are still better than the other two options (HPI & MCSI).

That is an option, but not a necessity... Most use it as a constant loss system. Battery technology is much better than 20 years ago. Cvetko used one of the batteries in his vids for a weekend at Silver Lake. He ran through 15 gallons of fuel ( Possibly more ) and never recharged the battery.

Rebuild the standard OEM IGN.

Still decent Honda components New or used (as well as Ricky Stator Stator'ss) are available, with New Honda type CDI's coming in December at BDT. Definitely keep away from aftermarket CDI's; all are Junk.

Or save up and spend the $$$'s and go CR250R IGN, it is the "best" Performance option as all others just don't work as they should. Plus; you can't beat Honda quality, reliability and performance.

I know when I added the CR ignition to my big bore, it was the single best upgrade I've ever done. Part of it may have been that I was previously using a 30 year old ignition that was getting tired, but still--wow! It starts much easier, revs a lot quicker, and just has more torque and power. I've seen the Motor City ignition and the spark it throws looks impressive. I just don't like the idea of having to use a battery.

85 ATC250R here. Did someone say kickback from an aftermarket chinesium ebay CDI? It took about three months to heal this one up.
Obviously I sent the ignition back and they balked at my request. I sent them the pic and was refunded immediately! I put the 86 style CDI on and it improved starting a bit but occasionally still does a little kickback.

**Any recommendations for an ignition for this machine are appreciated.

Telling it like it is; is my MO...

really?thats whey arlan had issues also and now changed something.
Interesting how others have issues, make negative statements, and don't get attacked.

Hello Carlos, there have been NO complaints on Motor City Spark Ignitions. Its unfortunate that you promote and run your business this way.
I post based on first hand experience, it's "unfortunate" you see experiences as an attack and not constructive criticism, I have no skin in the IGN game, unlike MCSI. Anyone can purchase 250R stock IGN's or CR250R IGN's new or used from any source, not just BDT Motorsports.

To be clear; the one MCSI IGN I have seen come through BDT, did not perform equally to a good stock OEM 250R IGN, and not to a CR250R IGN (not even close) on a ATC/TRX250R 85-89 on seat of the pants testing & Dyno runs on the BDT Dyno.

Carlos can you post the dyno results so we can compare them? That would be some great information to have so forum members can make an educated decision. Don't be offended, but your "word" doesn't carry much weight. Actual physical dyno printouts do.......

You were doing fine, till this misguided statement; "your "word" doesn't carry much weight. Actual physical dyno printouts do"....

Neither is True to facts; the first "word" needs no debating as it's a totally ignorant comment, the second "actual Physical dyno printout do", I used to post Dyno sheets, and got nothing but grief, as some would not accept the results....even from straight of the DynoJet printouts.

If MCSI want's to send BDT a ATC/TRX250R IGN to test run on the BDT Dyno vs Stock 250R IGN or CR250R IGN, I would be more than glad to post the results. That offer is Open to MCSI or HPI....either one or both are welcome to come to BDT and participate in all the Dyno IGN runs & test. Can't have more clarity than that....

I know a fella who has an early hpi ignition on his pilot cylinder engine. He has a kickback issue. When his buddy gets on his R and kicks it with authority (like you are supposed to kick over a high compression bigbore) it doesn't have any kickback.
Darren, correct me if I am wrong, but haven't you had issues with stock, CR, and now hpi ignitions?
That sure is a string of bad luck.....

I understand you have issues, specially with the Truth, Facts and Reality. Answers bound by those words, obviously scare you.

My offer & invitation to test HPI & MCSI IGN's vs Stock 250R & CR250r IGN's on the BDT Dyno is more than fair, and a lot more than any other Builder has offered to do to date. I can say categorically your so-called builder doesn't own nor knows what a Dyno is, therefore wouldn't expect any type of clarity or fact based results coming from that end of town.

Only problem I've had with oem is bad stator and flywheel, my last cr I don't know what the he'll was up with that one. This hpi I'll go in tdc give it a big kick and it kicks back so hard it blows my foot off.. I'm done with it and arlan. Action hooked me up with a good deal on a 02 and I'll see. Cr ignitions are the best upgrade.
