superjet cdi modification

[chad256]

Just pulled apart an old ebox from a stock 650 ski to mod the cdi, but when I pulled out the cdi I noticed it was already modded by protec. Score! Lol. Anyone know which way to turn the dial for the most revs?

Clockwise

More like does anyone know which two solder points to connect to mod it? I need to mod one right now... And looking back at page one on this thread from years ago, there's two sets of pictures from two different people and they show different solder points... I'm confused

bumping this for reference

Or just send it to me and I will mod it for you and you will save about $70 of what you will pay the big shops. Send me a working CDI and $55 and I will send you back a modded adjustable rev limit CDI.

hi i have a 94 waverunner3 701 would like you to do the cdi revlimiter just make it wide open

 

[MADMAT]

^^WHY on a Waverunner3!? No rev limits is for stand ups that do not go wide open in straight lines.

Before and after pics. Rev-limiter removed with no side effects. The stock porting is rev-limiter enough.

They can still free rev to 9000, that is over revving a 701.

Guess I should add that bottom end condition is really what determines an over-rev. And of course common sense. When I jump I don't hold the throttle pinned. I also have a blueprinted, trued, tig welded crank and all new bearings. Mine can't overspin if I wanted it to. Buy even holding it pinned in rough water I usually don't even rev 8k. I would have to be pinned mid-air to break that.

 

[kevbo]

It is about as easy to install a 60 ohm resistor and have an effective rev limiter. Without one it will occasionally over rev and every time it does bearings will skid and loads will spike. It all adds up to shorter crank life.

i did a mod in my 6m6 i jump it w 2 peaces of wire toguether but i dont feel diference my question is i have to remove the resistor by the way this yamaha motor is on a home made scooter 1/8 mile 6.59 @97 miles mph can any one helme out to get the rev imit out thanks are e mail me at tula_56@hotmail.com thanks

 

[cukie alicea]

this is w i did

They won't go to 9k. Not even out of water. At least my buddies 61x with cheater pipe in his sj won't. He clears it out full throttle for like 10 seconds after every ride. No rev limiter. Doesn't bounceloke a rev limit either, just hits a point it has no more. I never understood people wanting another 3-400 rpm so bad. Your timing would have to be so got dam good for that to matter.

 

[waxhead]

The reason for that extra rpm is not just for a number but so as your riding through the chop it doesnt bounce on the limiter and you get a smoother and easier ride.
plus the 6m6 one is very low

this is the scooter yamaha 650

I still think this is Winter crazy posting, but I'll bite -How is it cooled?

 

[cukie alicea]

we no use water push it to the water box and burn tires red to stage pick it up end off the tack

 

[cukie alicea]

i did the mod on the cdi but i feel the rev limiter at the same rpm i wonder if i have to remove the 90 k resistor

 

[cukie alicea]

that resistor needs to b removed ? thanks

Wondering if anyone has run into this mod with a 6r7-00 cdi.

I presumed all 650 had the same cdi. Found out that I actualy have a 6r7 (?) cdi verses the 6m6.

The pins are slightly different.

I'm taking a shot in the dark on this one but anyone know if the pins I want to connect the pot to are the ones I've highlighted with a blue marker in the pictures?

Any help appreciated!!!
