Well it is an rmk 600, orville mention its more agressive for the rmk models? Any idea if it would work for maybe a few miles, maybe 5 miles just to test and see if it would work? Would i risk damage to anything, the cdi, or my engine? Its got SLP twin pipes on it.

the 97 700 rmk or 97 700 is the box you want if it will work. hotter curve than the 98s later on and 99s.

These should give you a bit of an idea of the difference between a couple cdi's.

I have an extra CDI from a 98xc7 if you're interested. I thought I had a bad CDI and it turned out to be the stator. Make sure it's not something stupid like you're kill switch malfunctioning or a cable coming loose from the slide in one of your carbs(both are problems I've had). As far as the cdi's go, i've heard they typically work right or don't work at all. Good luck.

Why do i want another cdi other than the one specific for my 98 xc 700 engine?

Dont suppose you have one for the 99 rmk 600 also? And really since i dont know anytihng about the timing curve or anything, how exactly do those two compare, and would it work?

Ill PM you. Its not the kill switch, its only doing one side of the cdi, one plug wire. Also i tried disconnecting the kill switch after it started doing the problem just to make sure, and it didnt help. Its most definitly an electrical problem..

Ive heard the same thing, but maybe i just got "lucky" and got a shitty one that is working half the time haha..

Only other I have is 98 700RMK. They show how advanced the timing is at certain RPM's. The more advanced, the "hotter" it is. They show that the 600 is not as hot after 6000 RPM as the 700 so it would be safe to run on the 700. Just not as much power on top.

Ok thanks. But damn i wish i knew what it was for the 99 rmk 600, only know a buddy with that sled that i could try it off of. Now that i think of it, i think SLP might list it for their pipes.

Without looking it up, I think the 600 XC and RMK used the same CDI, but the 700s definitely have different timing curves. As far as damaging the motor with a different CDI, the 600 has a timing curve that is less advanced, so a 700 motor would be safe with a 600 CDI. As to the question of "Why a different module than your stock one", a CDI with a little more advance will help performance some with a stock motor/pipe. With twin pipes, retarded timing is often helpful to make more top end power. It wasn't totally uncommon for guys with twin pipes and increased compression to run 600 CDI modules because of the less aggressive timing curve (less chance of midrange detonation, more pipe heat for more RPM).

Ok thanks, so i should be safe in running that 99 rmk 600 cdi box, with stator in stock position, correct? I am running twin pipes, so i may even want to go with a 600 cdi box if it ends up being the problem, or should i go with the stock one for my sled?
