I bought a couple of these Honda CR450R Elsinore coils to test with.True it works. But it DOESN'T deliver optimum performance and optimum voltage to the spark plug so I say spend the whole $10.00 bill and get the most of your CDI.
Ewww, SNAP!... and quit being a cheapskate, besides what are you really going to do with the $2 you saved? You must really like Orange parts.
I run that coil and cdi unit on my Roketa 150cc scooter never had any trouble with it and it was a performance upgrade over the stock coil and cdi that came on m scooter, im a forum member on a couple scooter forums and many people use those parts on their modified scooters, I can't say how well they will do on our bikes but on the scooters they hold up well and do a great job in my experience.that is the coil I use it seems to do a very good job
Yes that is the most common there were some older models that use an AC Unit but the most common is DC like the one that is being discussed here.Does the GY6 CDI unit need a 12v DC source?
The balancing of a badly untrue crankshaft with a cdi has always made me laugh.....!Gee Zezzz KC don't go gettin the Gin thing. Your cdi is just like a stock Jaguar with that 4.7uf timing cap. Which has a VERY LOW TIMING CUVER , which exactly what I intend to get away from you why would I want to try something that has such a low timing for you would have I use wish I could turn it down even more why bother getting the bike out and starting it? The High Performance engines need advancement not retardation! If vibration is the problem you're trying to solve its not truly in the timing its in the balancing and the truing of the crankshaft. Retarding the timing to smooth out the vibration is nothing more than a band aid over a gun shot wound. It works for awhile but the inevitable is coming
Death to the bearings. Theres no short cut to balance&trueness ★★★★
HD sorry if I sounded like I was comparing your cdi to the jag, that isn't what I meant..... , several years ago when the jag came out the adverting of it suggested that it would make the badly balanced china girls run smoother and I remember some people claiming it eliminated most if not all high speed vibrations and I never believed that could be true... that is what I was referring too, not comparing you product to the jaguar unit because as you know....I know that yours is a much better cdi and it does not operate like the jag.Here we go again, my Lightening CDI Kit is NOT a Jaguar type CDI
the schematic and layout is different the components are different the function is different there is no timing curve it is true accurate advancement .
My Lightening is in its own class and there nothing that comes close in the Chinagirl class.
Remember it has a BIG BROTHER that BOLTS a TWIN BANSHEE coil that run Freds

"LIGHTENING DOES STRIKE TWICE"
I run twins on both my bikes!!!
At the 2014 April 12th SMBR event at Willow Springs we will be dynoing my pal HuffyDavidson's CDI and other China girl performance stuff.I do look forward to seeing some actual dyno testing results as well.
That was actually a quote from a general 2-stroke tuning guide by Eric Gorr. Gordon Jennings (long considered the golden standard in 2-stroke tuning guides) had this to say:Those are words of Jaguars concept that does not apply here. What I build works well and it's going to the track real soon and you'll see then.
People have been at this for decades, it would make sense to think that our engines, even with such poor quality, would follow the same rules as any other 2-stroker, the flow dynamics will be the same. I like to tinker as much as the next guy but ignoring time-tested tuning methods is settings us back, not ahead of the curve.Interestingly, the influence of mixture turbulence – which increases with engine speed-is so strong that the spark-advance optimum does not change much even over a fairly wide speed range. Indeed, from all available evidence, the ability of combustion-chamber turbulence to speed burning is so great that increases in peaking speeds frequently require a slight retarding of ignition, while advancing the spark may well give a small improvement in power at lower-than-peak engine speeds at the expense of maximum power.
