I need a new cdi for a 86. As I see it I have a couple options.

1. Find a old used cdi (which it did) and use it. The one the guy sold me was junk and i got screwed but thats beside the point. A old cdi will only last so much longer and back to square one again needing a cdi that is compatible.

2 Use a aftermarket one

3.Use a aftermarket one and retard the timing.

I have did all my reading on aftermarket CDI's and also wrote down all the honda numbers and cross referenced numbers off all four years of the bikes for their cdi's, stators, flywheel, and wiring. I'm at the cross roads of find or making a cdi compatible and so will everyone else one day because they don't make them anymore and eventually they all will die..... I know sad story. So I'm doing this now and hopefully save some people trouble or myself trouble and we hash this out. Does anyone know of any after market brand CDI's that has worked with NO problems!?? The brands I seen online was Hotshot (which isn't that the same as Rick's?),Rmstator, Dynatek, Rick's, K & L supply, Electra Sport, Arrowhead, and DB electrical (which serial serial number wise and price I believe was just another Unbranded CDI).

My problem is the kick backs and not rev all the way through but then I seen the bike didn't have the right CDI to begin with so that might be half the problem. I also read about a artical about the aftermarket cdi's doing that or other possible problems from a bad head gasket too, or wrong jetting. I'm guessing if you can find a CDI that will idle and rev though all the RPM's then half your battle is done. Then to just address the kickback problem. Which I believe you can buy a timing plate and retard the timing a little to fix the problem then right? Also I read about advance and retarded timing. The advance timing gave you more middle band with less rev but the retarded timing gave you less in the middle but more rev so in the end I believe retarding the timing on a aftermarket CDI might fix the problem? Yes or NO? I mean if its firing too early thats where the kick back is coming from right? I would like people input on stuff they have tried. Like the brands, what they were like, timing with dif brands, kickback problems they solved and what their perticular problem was that was causing it and how they fixed it, etc etc. Maybe not reving all the way through and it was a electrocal problem. Anything to do with the electrical and kickbacks and timing etc etc.

I think I"m just going to get a cdi in the mail tonight and have it by the weekend and start mashing out this process of trial and error and also order a timing plate. I have a 86 trx by the way and I'm assuming 86 flywheel and stator but who knows when you buy a used 250r. Thank you all for your time and help!!

P.S. Carlos I tried writing you buddy and your inbox was full and I even tried replying to a conversation we had a while back and even that wouldn't go though so just giving you a heads up if your reading this I tried to get a hold of you and also clean out your inbox lol.
 
bdt is the only one that sells ones that actually work..he isn't on here anymore.if you need one you have to call bdt and order one from ricardo...as for the rest...I have never checked but imo the problem with the aftermarket cdi
s is too much initial timing,and not enough total so with that being said an adjustable timing isn't going to fix the problem.

Thanks for the tip. I called BDT and Ricardo just happen to answer but when i talked to him he said 86 was discontinued which i told him i knew that but I read online from carlos that they carried CDI's and also you had said something. He then said he had a cdi for a 88 and 89. I asked him about it working or not and the timing curves and wiring etc etc. He said he didn't know that kind of info but that the cdi's was on back order. I asked by back order as in they don't make them no more so they never will come back in. He said no that they will be in about 2 to 3 weeks. I then was puzzled and asked if they don't make them anymore how are you still going to get more in 2 to 3 weeks. He said they don't make 86 but that honda makes 88 to 89. I found that weird because my understanding is they don't make any of them. I even looked up shindengen and honda and trying to get contact numbers and email people the problem and find a work around is hard.

What do you meaning initial timing is too much but not enough total? If its to much initial timing at start and idle then it only gets more advanced as the rpm's speed up which would be more total timing. I appreciate the help man! I know there has to be a leget cdi out there somewhere that will work with these bikes. I mean what happens if bdt never gets them in or they do but they eventually quit carrying them? I ask him the brand or model number or something and ricardo said he didn't know so I kinda in the dark about this cdi they have.

P.S. what happen to carlos?

P.P.S. I also called my local world of powersports and they said both years 88 and 89 was discontinued so I guess whatever the cdi bdt has isn't OEM.

I just looked at the parts numbers and 88 has the same stator as the 86 so the difference is in the cdi and flywheel. 88 and 89 have the same cdi and flywheel just different stator and wiring (because the connections are different on the 89). So I'm guess if I can find a HB9 cdi and the 88 or 89 flywheel with it then it should work on my 86 because they have the same stator as 88 and it worked. I just tired of using old parts because a guy already got me for a 100 bucks on a used HA2 already. Also how long will this HB9 last me?...
 
IMO Don't ever pay over $40-$50 on a used one. The K&L HB9's are GTG, that is what Carlos told me. That said the only other way to get a good one for sure is from BDT. Now I have bought 2 on the marketplace in the past couple of weeks and both members sold me great working ones, which I tested.

Im pretty sure all year CDI's work with all wiring harness's, so it doesn't matter what year cdi you get. Opel correct me if i'm wrong.
 
carlso was ordering dozens of them at a time.that's the only way they would make them...as for timing..yes too much initial timing.thats why they kick back...but they don't have enough timing in them to have enough total....as for 88-89 all oem cdi's have been discontinued for many years.carlso is having same co make them for him.but has to make a large purchase to get them to make them.

Lol, and he's got that flow bench too right? Your best bet for a cdi is buying a used one...
 
Don't listen to this guy, these people you have to just tune out and act like they don't exist.

K&L im pretty sure are good to go, next thing is to buy new from bdt. Other then that, buy used. Everything you tell them just goes through one ear, and out the other.

Sorry we disagree, BDT is no longer a site sponsor here. I gave good advice, buying a used one that is truly OEM is much better then buying something from BDT which may or may not be legit.

Yes buying a used OEM is the way I go because I can't fork out over $100 for it, however OP said he wanted 'new'.

OP, I have gone through Carlos for a dozen things on my bike and about to send him 2 motors. He's already done work before on them. He's taking my calls on Sunday nights to help me figure things out. He is a good solid man. You have to take these things people say about him with a grain of salt.

Because its ridiculous you people are still going after Carlos for all that he's done for the R community, and that whole flow bench thing was debunked a long time ago. Im not going to argue with.

I'm done with the argument over bdt.
Thread jack; Michael were you the one that had the CT graphics 250r with the arched swing arm?

My last post before that was offering to sell somebody a tail light? Not sure how you think that involved bdt... I'm sorry I don't get off on my post count, not sure if you do? I think what I gave was sound advice, buy used, that way you know you are really getting an oem unit, not something bdt tells you is an oem unit which may or not be.
