I know this has been beat to death but i just want to know the right 250 ignition to get for my 88 500 motor so if u guys would be so kind i would appreciate it thanks.

they will all fit. some just have alot of extra wires

Well that certainly narrowed it down for him.

Ya, im looking for the best way to go with if danny is around i would like his opinion to.

97-01 requires machining to make the stator fit. 97-98 have an extra wire to the carb. 02-07 have extra wires also, I don't know what they are for. Maybe a power valve or TPS? 97 and newer are digital, I don't know if this makes them better or worse.

do u know what wires u have to use?

No, not really. I did find some information on a karting site, but I didn't bookmark it.

ill double check my manual and i could be wrong but i thought it said there was a small computer built into the cdi. not sure how it would work with loose wires.

I have two new Service Honda / Electrosport digital ignitions to sell...

This is incorrect.

I've owned 99,00,01 CR250 non of which had "extra" wires for carbs. The wiring is direct bolt on other than the coil hook up wire is differnt where the male/female juncture is. If you use a 250 coil it won't matter. I just changed the connector and ran the 500 coil. The machineing was easy with a drill press and a flat bottom carbide burr on my 01 stator.

I'm pretty sure digital is better, but I'm not educated enough to explain why. Honda didn't switch to it because it's worse did they.

later models had electronic powervalves and some had TPS on the carb too.

I just did an edit. I know 97 has an extra wire to the carb, and i'm pretty sure 97-98 are similar. I have an 00 ignition on my bike, so I know they just need machining, no wiring changes.

Yes and no. They're a real bitch to start for some people and that does include me. Others seem to be able to make them work just fine. If anyone wants a try and buy, that works for me.

well i cant find that computer shit. im sure i read it somewhere though. you would think something has to make the tps, powervalve and timing curve work together.

I know a racer of drag machines, he told me to find an 01 set up that the timing curve is more agressive and the spark is hotter and no extra wires. I didnt ask about other years but he really likes the 01.

sweeet!

Im going to have to look around for a 01 if it will definetly work on my 88 i have some time im not doing it until the hillclimbing season is over.

mines in the mail from the states. cant wait

what is the going rate on 01 ignition?

i got mine for us$150 off ebay. but they go for up to 250-300 complete. you just gotta look around on the cr250 section.
