ok hello all i will try to keep this shorter then my introduction post where you can see my project http://www.fjowners.com/index.php?topic=11323.0 (http://www.fjowners.com/index.php?topic=11323.0)
my problem is i rewired the bike completly and am not going to be running a dash. its an 84 so my question is if i want to run a revlimit do i need to somhow waterproof and tuck the circuit bored style stock rev limiter or is it possible to use a newer cdi box? i discovered using the search feature the newer cdis have built in rev limit? was not sure if this would be the best place to post this if anyone recomemnd it be moved let me know and i will post in correct section. thanks
Just put a rev limiter on it then.

I've got this unit on my Z1R and it works great (prevents the unwelded crank from twisting). I tried the throttle when this unit was set at 6,000rpm and thats exactly where it stayed, no popping, no weird noises just sat on 6,000rpm.
The rev limiter is part of all CDI ignition of all FJ's. Not the dash, it just has the tach to tell you were the revs are.
Randy - RPM
then why dos the diagram for 84-85 show an over rev limiter switch with 2 wires and all other diagrams show no rev limiter at all.
I just had a look at the GYSM and I am not sure what that is, I see it mounted up high in the fairing.
Pat, do you have any idea of the switch?
Randy - RPM
No I don't.
I have had my '84 zing well past 9.5k several times and have never felt anything like a stutter, indicating a ignition cut off...
I've bounced off the rev limiter several times in my Miata, so I know what one feels like.
Which reminds me....Randy, you have to do something about those WFO 3rd gear power wheelies I'm having...
I never had that before, until you worked on my bike.... :shok:

I'm still scared to go WFO! I did pull a nice 3rd gear wheelie with Diane onboard the other day... getting on the freeway and ramping up to speed. I decided the best course of action was to pour it on and get ahead of the traffic. At about 1/2 twist and 6K the front lifted about 3" I'd guess. Held it for maybe 100ft or so until it gently set itself down (yes, we were hauling ass at that point). Diane's actually getting pretty comfortable with this shit... as long as she doesn't know that is.
Frank
Yea Frank, I can imagine when the Wizard comes on the cam with your FCR's...
I was surprised at mine with 18/40 gearing and all....it's really quite fun, when you get used to it.
1st and 2nd gear, you would expect, but 3rd?
Whooohoo
so noone has anything on this huh? there was a circuit bored in the dash with wires going to the cdi. sure seems to me like an external rev limiter. someone needs to know.

Frank,
I've got near-as-makes-no-difference, 100,000 miles on motorcycles over the last 28 years. Throughout that time, girlfriends have come and gone and most have taken a ride or two on the back of the bike. As anyone who has ridden with me can attest, I'm not a hot-dogger...I rarely take chances and try to stay well within the limits of mortality. Some of them have enjoyed it...some have LOVED it...some have just tolerated my passion and one of my dates even passed out as soon as I made the first stop for gas. :shok:
I've seen you ride...WITH Diane on board...always controlled, skilled...but often with a flare for twisting the throttle. She steps off and has a smile on her face every time and a look that implies, "What? It was just a ride..." You've got a keeper there! :good2:
To keep this on topic, I can give you the number of the girl who passed out...she will limit your revs very efficiently. :yes:

I read that as morality.
I'm not sure it changes things too much. :)

:rofl: Mortality is a binary function...Morality can fall anywhere on a sliding scale...Where I fall depends on who you ask, I suppose. I do have a rev limiter, but it might be set higher than others. :biggrin:

OK - I'll bite!
Great project you have going -- and a lot of times those projects will take you out in no mans land by yourself.
Sounds like you are there. Oh well, just gotta figure it out then post it up for the benefits of others -- part of being in the club....just like the banter your post spun off. Most of the front and rear wheel swaps started this way. I remember Frank Moore trying to figure out if the FZ1 stuff was coin to fit before buying the salvaged bike. No one could help him and he had to take the chances and figure it out. Now it's one of the "standard" swaps if you will.
Sounds like you've done your home work and have figured out a good solution where no one else is sure. Go for it!
Another alternative is fitting an entire Dyna ignition system and getting a selectable rev limiter.
But then again isn't the fighter attitude more like piss off we don't need no stinking rev limiters while we're burning the place down! :diablo:
if cost was no issue brother i would have a dyna programmable on there already. along with the td05h snail i have sitting on the shelve (with all suporting mods) and a nice new inverted front end. but.... in this economy and all you know lol. and as far as the fighter mentality its not so much that i need the revlimit but at this point almost principal frustration. it is nice to have tho if ya go down with no tip sensor or any of that. got hit by a cage in very slow traffic last summer on my cbrf2 fighter and it sat on its side bouncing rev limit for a good 35 45 seconds while i picked myself up threw my helmet at the car that hit me and walked to pick up my bike.
I'll bite.
Why do you need a rev limiter? What kind of exotic motor combination are you running that can't handle being overreved, and yet wants to be spun like that, blasting through the revs?
Maybe fj1289 can help here, but I'm (still!) in the process of building a mild FJ up, and one of my design criteria is that max allowable rpm is 9500, with an aim at getting peak power at 9000. I'm sure I'm leaving some on the table, limiting myself, but I'd wager that I'm saving a ton of heartache by not spinning the combination like it's 20 years newer, either.
IMO, if you're making power so high that you need a hard limiter, you should look at your cam timing and make a quick tweak.
ok champ. my last post should have said "i dont NEED a rev limiter but its nice to have if you dump and throttle sticks wide open" you just came off as a huge douche. just saying.
Well kiddo, you've now had a unit linked to you which would limit the revs. You could arguably go to a tether switch if your concern is falling off and having the throttle held open.
How much more hand holding do you need?
If you're bent on using the 84/85 TCI unit that connects to the dash as shown as #8 in the GYSM for the 1100's, you should do some research about it here (http://www.fjowners.com/index.php?topic=8769.msg81932#msg81932) and the confirmation of it doing what the first link says it will when partially disconnected here (http://www.fjowners.com/index.php?topic=8270.0). You'd have an abysmally low rev limit then unless you got fancy and respec'd the unit internally, and convinced it to work for your application.
But frankly, I'd imagine that you're not remotely bright enough to do that.
Just saying.
ok sport. im not bent on anything. did you read any of this before jumping in with your condescending attitude about my "exotic motor combination" if you were not so busy being a genius you would have noticed that options for using different year TCI was part of the question. i understand your frustration with me though i know it cant be easy to "help" dumb people like me. thanks for the hand holding you have really just been super.

Only limiter on JDM that I know of is speed limiter which cut the ignition at around 180kph - my '91 had that on the back of the speedo.

Actually, the dead-man switch that Andy threw out there seems reasonable if over-revving during a get off is the problem. Had one on the Yamaha jet boat. Clip it to the switch, coily-cord to the vest and poof! Instant engine kill switch should you and the bike suddenly part company. Dead-simple, reliable and little to nothing to adjust. Oh...and it's an OEM Yamaha part! :good2:

On just about any modern watercraft, there's a kill switch that's activated if you fall off. Basically, so your boat or Waverunner doesn't keep going, essentially abandoning you in the middle of the lake and crashing into a dock full of tourists. It's just a coiled cord that you attach to you on one end...and the switch on the other end. If you go flying off, the little clip pulls out of the switch opening a circuit...killing the engine.
They all look something like this:

I had a 2006 Yamaha SX230 jet boat for a while (Twin marine-rated Yamaha R1 engines!!!) that had this as standard and is in the parts catalog. Regardless, it's about a $15 part and is drunken PWC-rider FOOL proof! :good2:

Here's the thing. Many modern day bikes have a tip-over sensor, 'bank angle sensor', 'tip over relay' or 'tip over/ shut off' switch that will kill the ignition if the bike winds up on it's side. I just did a quick Google/ eBay search and it seems that many/ most folks want to disable it/ remove it from their bike. Accordingly, if you want to go against that trend, (and actually add one) -these sensors are readily available on eBay for not a lot of $$, All you'd need to do, is figure out how to wire it in and mount it. There are literally hundreds of them on eBay... No bothersome tether to mess with.
Good luck

Nice find Dan! I was being a bit tongue in cheek with the overly-simple tether solution to illustrate how complex the answer was getting. Some sort of programmable ignition ECU box? I'm still not sure what the overall goal is, but I think it's to stop the engine in case of a tip over. ...and BEHOLD!...apparently they put these things on modern motorcycles all the time! I really had no idea.

Well over a thousand of them on Ebay for under $10! Cool. It makes me wonder why everyone is removing them? What problem are *they* trying to solve by taking it off? Some are called a "bank angle sensor"...Do those tie into a traction control system to change engine dynamics in a turn? Maybe that's why they are being removed. Also...I wonder if they put out a variable signal depending on the angle or just open a circuit past a specific angle? Makes me want to pick one up and play with it on the bench. :yes:
