aftermarket CDI units

[rcnut]

Question. I have an SSR Classic 50. Thru reading forums and e-bay descriptions, they say I have an A/C system. Headlight on only with engine running, runs without battery, CDI box unit dimensions. I've installed two different units, wont start. Called SSR Motorsports and was told it was a D/C system. Installed new D/C unit, wont start. Only runs with stock CDI. Am I missing something??? Help!!!!!!

so it runs with the stock cdi only...makes me think the plugs are somehow not making a good connection in the others.

A few of us have tried the after market cdi's and found they're not much if any better than a stock cdi.

Thanks. Didnt think I'd gain much, just a cheap stab. Averages around 40 on flat ground. Flat blacked it, red rims and white threw some white walls on her. Had a hot rod buddy rat rod style hanpaint pinstripe it. Added oak runners on footboard platform. I'll try to upload some pics.

if u get a known brand,ncy,naraku,etc..you wont get more HP but timing,rpms better idle..

checked tabs and connections. seem to be ok. I guess my question is, if neither an a/c or d/c cdi unit works, should I just scrap the idea? Also, how do I post a few pics of my scoot???

Quick question. Has anybody used the Denso ITF16 spark plug?

This will explain what a CDI is and does...

Some do have rev limiters, many don't. With a 49cc 37MPH may be a power limit more than anything else.

I put a racing CDI on my 2T it made not one single difference . I have a restricted exhaust ( waiting on a MMG pipe woohoo ) . Many already have unlimited RPMs already . Its better to tune the CVT with sliders instead like these Dr Pulleys mainelyscooters.com/blog/2012/06/15/dr-pulley-sliders/
