first thing i want to know...is it safe? i would guess its safe to assume the rev limiter is set where its at so u dont risk blowing your engine....correct?

and i have already found it annoying bouncing off the limiter in the sand (havnt had as much of a problem on dirt)

what are my options? ron woods? (300?)
vortex?(?)

do those two completely do away with my rev limiter, or just give it a higher limit?

if they do completely cut out the limiter, is this safe? isnt there a really high risk of watching that purdy rotax 650 shoot shrapnel?

just curious if this is a mod i should do....

 

Roost,

Changing the CDI is one of the easiest ways to add power to the DS 650. There are things to consider. The Ron Wood Racing CDI and a few others eliminate the rev limiter. However, with the stock motor, it is very difficult to generate enough RPM to reach the point to where the valves float and then cause damage. Also, there is very little usable power at that RPM range where damage could occur. Therefore, the only reason why someone would force the stock motor to that RPM range would be stupidity, or an accident. To curb the stupidity factor, many get a tachometer to help keep the RPM down and when to shift! There are also tether kill switches that would kill the motor on a roll over and keep at bay any accidental damage.

If you still want a performance CDI that has a built in- but raised - rev limiter, you should consider the Vortex CDI.

Alba and Ron Wood Racing CDI's are rummored to be exactly the same. Graydon has a CDI for the DS but it offers a rev limit. Then Vortex also makes a CDI for the DS and it offeres several power curves and all of the power curves have rev limits. Vortex is the only CDI that directly hooks up to the Baja DS without the need to rewire connections.

thanks for the info update!

do you know how much the vortex is? and also where can i find it?

 

vortex is 400...you can find it all over the place..
