After all the talk about how good the ruckus run with a CDI, i gave in and talk my wife into getting me one as a father day gift, along with some variator weights, i am sad to report that the improvement is not that great, but i think is because i have the scooter geared so tall it did not get to 8k before, it doesn't get to 8k now  But any way, i think the install in Battlescooter is great, but i decided to include some pictures that should make the install clearer, so here is how the CDI cames  then you have to remove the connectors, so you can get to the wires they talk about in the battlescooter, like the red/green wire that becomes two, so here is the same system without the connectors  finally the whole system installed in my ruckus  |

I love mine. I got a cdi and variator combo also and I installed mine last Saturday and I am able to 40mph on flat ground with both,and hit those two wavy lines on the overheating warnig on a medium hill, without it I was at 37 or 38 (with Daytona)mph hard to guesstimate on speedo. I haven't posted results because I think these numbers will improve, my starting point on this Ruckus was 35mph on my other Ruckus it's 37 mph so maybe I can get 2 more mph, my shims need adjusting and my tires are crap I think thats where my lost 2 mph's are, I am waiting on my Pirelli's to get here, so that should help and shims will get put to spec. Both are stock except for 3 5.5g weights and Briggs & Straton air filter. My Daytona variator is set up with 3 5.5g weihgts and 3 6.0g and those also helped with my top speed compared to the stock modded variator I had, accel seemed about the same but my stock variator already had lighter weights but an unshortend spacer so I think thats why I didnt notice I big difference it accel but got +2mph on top speed. When I go riding now I am way out in front of our riding group, before my fat "edit profanity" was always in the back. Bad news is my I think my friends already ordered a cdi, and variator kit for theirs so this wont last long. I also run stock jetting and air box. I spent all day testing my opened up air box with every jet and shimmed from .5mm to 2.5mm and got some decent performance, but stock was the best for me.

 The problem is that i play with the variator so much and i got it so tall i need now to play with the carb and weight to get the CDI singing in the right tune, now it feels like i am back to stock, i still have friday to play so i can enjoy her on the weekend

I've always wondered whether my CDI is working. Do you have any meter checks I can run to know whether the CDI is functioning properly? Other than runs, cause I don't have a tach yet...
I'm thinking like continuity checks, etc...
Thanks

a really simple way to check is to run it down a steep hill. If you motor doesnt startbackfiring when you hit about 38-40mph and not allow you to go any faster, its working.

I think it might be which is why I would like to meter it, but I don't know what to look for.

Well if you installed your CDI and the ruckus is running then your CDI is working, as the CDI controls the spark

Well you can partially install it. When I first tried to install mine I connected everywhere except were you need to solder it and it ran the same as without one. I have no idea how it worked but it did. It didn't do what it was supposed to do but it ran.

???That's odd, i would think that if you hook the coil to the CDI then the CDI will have to sent the signal to fire, maybe they have a bypass, in that case then you need a tach to make sure the CDI wotks, mine did not get to 8k now but i do not have a hill to test the rev limiter, i might have to use a long bridge to make the Ruckus pass the 8k mark. |

it is the rev limiter that I am concerned about.

what are the wires that control the rev limiter? can we figure that out?

I do not think that there are any wires which control the rev limiter, as the CDI only have power, ground, signal and coil wires, so the CDI provides the ign feed to the coil after 8k instead of cutting every three revolutions like the ECM does, so if you are not feeling any ign misfiring at high engine speed (about 38-40 mph) then i suppose the CDI is working, what i have not figure out is how the CDI controls the cold enrichment valve, because there is only one wire going to the ECM and that is the wire that controls the coil |

I don't have a cold enrich any more. What do the green wires control that come into the relay?
