Im looking for a littel help with my nitrous kit..I keep burning my plugs off and was wondering if any one has any good idea.. im maped on the rich side.. timings 2 deg retarded.. and i run a 1 step colder plug but still go through a set every 10 or so sprays.. dose any one make a nitrous plug for the 954??? or any ideas to fix the problem?

[cbr900racer77]

first off...stop spraying it. If you are burning plugs you have something wrong. I've sprayed 80 horse on my 900rr before and plugs looked fine. No special plugs are needed. How much are you spraying? What fuel are you using? Where do you have fogger mounted? I'm not really a big fan of dry shots, but if I were to use one I would take bike to a professional tuner who would put it on dyno with a wideband and make me a nitrous map.
With what little info you have given, I would guess you have a detonation problem. There is alot of fuel out there that you have to be real careful with. VP U4, U4.2, and U2 has low octane rating, if you don't have it tuned right it's gonna hurt some parts.

[stealth954rr]

K, I have a custom map on my bike tunned for spraying and the fogger is in the front of the air box before the air filter.. i have the air baffel removed from the air box.. and full hindle exhaust.. on the dyno it shows 14 to 1 air fule when spraying.. i use a 110 race fule also..

[cbr900racer77]

14-1 shouldn't be burning plugs. Contact a guy on here, goes by silverbullet. He has a 54 with spray. Sounds like everything is done right on yours. I don't have enough experience with dry systems to help you any further. I have a couple of buddies with busas that had fogger off to one side and it wasnt distributing everything evenly among cylinders and they hurt some pistons. Give that guy a shout and see what he can come up with. Sorry I can't be of more help, my experience is with carbs and wet systems.

[stealth954rr]

well thanks fot trying anywas and thanks for the info

what are you using for your map? I have heard of guys having problems with the powercommanders failing and leaning out the bike. I opted for an instant rich box for mine. It gets a signal from the solenoid when the system starts to spray and instantly maxes out the injectors. That way I don't have to run rich when I am all motor and I don't have to change maps for the track. Unfortunately, mine is still a work in progress and I am about 2 or 3 weeks away from my first test and tune time on it, so how it runs on spray for me is all theory for now.

[cbr900racer77]

I've never heard of the instant rich box. Do you have a link? Sounds like a great idea. Can you adjust it? Personally, if I ever do break down and buy a FI bike, I would install a wet system so I know for sure it's getting enough fuel.

I'll have to look for the link and post it up tomorrow for you. There is no real adjustment to it, it is basically like an on/off switch that sends full voltage to the injectors to max them out when I am spraying. I have a controller for the nitrous that limits the rpm range that it will spray in and I can set it so that it has to cycle through that range a certain number of times before it starts to spray as well. I can (and will) use this to keep it from spraying in 1st gear so I can launch the bike really hard in first on just the motor, then start to spray in 2nd gear when I am less worried about traction.

954 racer if you don't mind me asking - what controller are you using?

I'm thinking about adding a 30 or 40 shot and I just bought a hub for my PCIII so I can switch to a nitrous map on the fly.

What I really want is to be able to arm the system and have the hub switch the map in 2nd gear at WOT and start spraying. I don't think there is any way at the moment to do this exact thing. I may have to enlist an electronics friend

I really don't want to be running super rich ANY time that I'm off the nitrous. But I don't want to blow my bike up either.

Thanks.

I am running an instant rich box that gets a signal from the nitrous solenoid and then sends power to the injectors to max them out. I also have an rpm window switch from dynotune nitrous that allows me to limit the rpm range that the nitrous sprays in. It also has a feature that requires it to see that rpm window a certain number of times before activating. That way I can run all the way through first gear on the motor, and the next time it sees the rpm range I set it to it turns on the juice. If I wanted I could set it that it has to go through that range enough times to only spray in 6th gear, but what fun would that be? LOL I'm thinking that you could tap that same signal wire from the window switch to control your hub and your nitrous solenoid.

I still have to invest in a powercommander so I can play with the map and hopefully see some gains on the motor as well as the nitrous, but for now the instant rich box allows me to run the stock map when I am running all motor and increase the fuel when I am spraying.

The fast fi box will make it real rich. I sprayed 50hp and it was still rich so I took mine off and had a custom map made, it should be tuned t around 12.5 to 1. 14-1 is too lean.

interesting......I will be getting mine on the dyno soon to see how it runs and if the box is doing it's job. I'm only running a 40 shot to start though, but I will have to watch for that when I run it. Might have to get a powercommander afterall.

[SilverBullet]

Hello. I run a 40 dry shot on mine, and I have run a 60 shot. I was trouble shooting a problem on the dyno and the instant rich box, which is made by MPS, so I disconnected it and changed to the 40 shot. Turns out it was one of my connections; I just haven't had time to put it back on.

I also have my NOS jet going into the front of the airbox. With the 40 shot, I have the power commander set 2 bars above normal for the "just in case I spray". The 60 shot worked well with the MPS FFI box.

I also say 14:1 is too lean and thats whats causing your plugs to melt. I've only melted mine once, and that was using the 40 dry shot and taking another bottle and opening it up at the snorkel. The dyno read 197rwhp then dropped hard so we pulled them to find them melted.

I'm adding the pciii hub so I can switch maps - and I'm going to edit my current map to be my nitrous map - just richen up the mid and top end. I'm installing a Zex dry kit and using their TPS switch... hopefully that will work out well for me.

I really didn't want to spray in 1st - but I stretched the bike 6" and lowered it. Hopefully with a 40 shot it won't end up on top of me at the strip.

I also noticed that with the hub I can use it to fire the nitrous solenoid - I can have it open at any rpm and TPS position I want. That may be a better option. Or maybe I should just use that wire from the hub to light a shift light so I don't mis a shift and blow the thing to pieces.

Any last minute advice before I start all the installation on this?

Thanks.

nice seeing these posts....I was starting to think I was the only one spraying one of these LOL

Not spraying yet. But soon. Man I went to the dragstrip once a while back on the 954 and was hooked. Stock height, and stock length I was beating my buddy's zx14 - but our track is only 1000 foot. My times were terrible -9.5 hah! But I beat him.

I put on a full hindle exhaust - remapped and went back and ran a 9.0 - still suckin because I can't launch the thing.

Now I'm stretched 6" over - lowering link should be here today or tomorrow and I'm strapping the front plus I got a new rim just for the drags that I keep a Shinko ultra soft on. I'm hoping to hit 8.5 or better this Saturday.

After this weekend - when I go back I'll be spraying.

What's your setup?

stretched 6" and lowered as well. The guy I bought it from tried strapping the front end and didn't find any real difference, but at the time it was still stock height and length too. I'm putting some serious thought into some cut forks that I found for sale to bring the front end down that way. I've only had one track day on it so far and it was before any mods, had a worn out clutch and it was my first time drag racing a bike. The times aren't even worth mentioning

I'm hoping that with the set up I have and a good launch I can hit somewhere near a 9.5 1/4 mile on it

What's your nitrous setup? Where is everyone mounting the bottle?

I really didn't want to put mine on the swingarm. Looks like the kit will actually be here today though so I can try and figure something out.

I have to resist the urge to throw it on the bike before I go to the track tomorrow. I want to take my time and do a nice install.

that is the BEST way to go with nitrous. Take your time and double check EVERYTHING. As for mounting, not alot of choices. Also, spend the extra bucks and get a good progressive controller. Summit sells a great one for about 220 bucks (that's the one I'm getting soon as I get the 997 together and tuned as good as it can get on motor). It is a dual ramp and is VERY small. Also make sure you have some type of safety shutdown to kill nitrous in the event it goes lean. Dynotune makes a great lil A/F gauge that has a built in kill. one word of caution....that crap is ADDICTIVE!!! Be safe and have fun!!

Haha.. I know it will be adictive. I'm going to have my machinist friend make a bottle bracket to mount the bottle on the left of the bike where the passenger peg is now. Should look pretty trick- it will be at the same angle and height as the exhaust on the other side is.

Got a link to that controller?

Thanks.

My bottle is in a bracket in my swingarm. I prefer having it there instead of outside the frame, just in case I ever lay it down, I'd rather not land on the bottle.

Well I ran a personal best of 8.60 (1000 foot) on my bike this weekend without nitrous. I put a better rider on the bike and he ran an 8.18.

Unfortunately now my clutch is DEAD. Slipping like hell. Is there anything better than the OEM clutch for drag racing? Everyone keeps telling me to go OEM again.

We put this same ZEX kit on my buddy's GSXR 750 this weekend and he's running hte 45 shot nozzle - runs like a bat out of hell.

I think I may jump straight to the 60 shot but with a very rich PC III map and some failsafe precautions (window switch, etc.)

Also my bike runs SO hot - 220 degrees a lot of the time - especially on those hot nights at the track. I understand that will cause my clutch to fail pretty fast doing hot laps. What do you guys do to keep the 954 cool while racing? Different coolant? Fan mods? What?

Thanks.

Hi, i've just fitted a orient express lockup clutch kit to my 900rr outlaw bike, it runs with a 7" slick so my stock clutch became a problem. contact Ken at orient express and see if they do a kit for your 954.

[SilverBullet]

My bottle is in the trunk beside the airshifter bottle. They both squeeze in there. (1lb bottles).

Schnitzracing.com also has the progressive controller, which I recommend over the Summit. Just preference though, and probably 90+% of the controllers being used are made by Schnitz.

That's pretty slick. I have a 2lb bottle. I'd love to be able to get it in the trunk but it's not going to happen. Especially with the PCIII, hub, ZEX tps switch, and now the zex window switch all piled in there

What clutch are you running in your bike SilverBullet?
