Silly question, but do the performance CDI boxes do what they say? Can the CDI also be reprogrammed as well?
If they say that those CDIs modify... how to say... "ignition curve" - then they are telling the truth.
And yes, beside few pre-programmed... "ignition curves", they can be reprogrammed.
Just wait for fresh "humabeing"s Taobao links. Those CDI units are more than affordable.
I've ordered a performance one (6pin) of ebay £9 from redcicles. Hopefully it lifts the limiter and adds some oomph higher up.
Would like a better one with some control from taobao, but I'm struggling with the website, be good if they could explain things for the european market to order stuff as google translate is not being helpful, as soon as I go onto a new link such as add basket, it stops translating as I've seen a few parts that I would like.
To order stuff from Taobao you need to use an agent which is a company that handles the ordering process and international shipping for you. This is because most sellers on Taobao can't accept international payments. I use Taobaonow as they offer reduced shipping rates and they have good customer service. When ordering you copy the web address of the item you want to buy on to their ordering page, pay the cost of the item and the postage to the agent, when they get it they will re-package it if nessesairy, weigh it and you then pay the international postage. The international postage is quite expensive for heavy items so keep that in mind.
I'm not sure why but humanbeing has linked you a ignition coil. Here are some CDIs that should fit your bike if the redcircles one dosen't work. Your bike is a CBF125 clone right?

Thanks, will look into it. Yep a CBR clone. Will find out tomorrow when CDI comes.
Looking for aggressive cams as well for the 156fmi.
Any bigger carbs fit on, as the stock one is a 26mm from my measurement the other night. If a bigger adapter to engine and carb would be fitted then a bigger carb could be a possibility.

CBF125's bore is 52.4mm. His bike is stamped as 156FMI, which suggests it's similar to the good old CB125J.
You can fit a bigger carb without an adaptor, I changed mine from a 26mm to a 30mm and it fit pretty well. I belive you have a PZ26 by default and a PZ30 should be a direct replacement. With a bigger carb you will lose some low end but gain some top end power. Getting the jetting right will be a little difficult however, it was fairly easy on my bike because I already had a 150cc big bore kit installed but with a 125 it might take a fair bit of trial and error to get it spot on.

You can find few more than affordable carbs on Deal Extreme, some PZs and CV type.
Thanks, any idea by how much my revs will increase by on a performance CDI unit, at the moment I'm flat out at 9000rpm hitting ~64mph. Using a smaller front sprocket as I'm quite a big guy.
Oh, any idea if my bikes ac or dc on the cdi side?
Hi revs will kill your engine.
And I don't think that CDI limits revs on your bike, and, if limits, it's not because manufacturer wanted to limit the maximum speed and power. Maybe just engine design is not intended for high revs.
I'm aware of what revs do, my YBR would sit at 10-11k doing 70-80mph all day long with no mods, this little engine is only limited to 9k, an extra 1k would be perfect, not planning to run it into 12-13k redline. Just want the bike to get to 70mph and hold it as my 19mile commute (38miles a day) consists of a 3 lane 70mph road. That's all I'm after, so any other mods or ideas are appreciated, I'm determined to get this bike to do what the yammy could do.
I was going to say that Chinese engines aren't as strong as Jap ones but then again I've done hour long trips at 10k rpm before so I guess they aren't that bad. After you have done your performance mods you could put your bigger front sprocket on again just to keep the revs down a tad.
New CDI is not working, wiring seems correct but I have an additional cable, where the two pins are, my old unit only has one pin, but the new unit has two pins.
Led is flashing as I'm trying to start up, any ideas?
Try to find proper spinout schematics for your bike's stock CDI and this new CDI unit. Maybe you'll make it work after moving some cables.

Thanks human, I watched that video earlier and I believe I have a DC system and the CDI unit I ordered is AC :hellfire:
Ordered a DC one tonight, will update progress, should be here on thursday.
is your bike a CG or CB based engine as trhe CB based engines will rev higher due to being a OHC design, I get what you mean though I used to comute 40 miles a day 20 to and 20 back from college on a 50 and I always wanted it to just do abit more to be comfortable in traffic on dual carriageways.
just looked at your blog did you fit michelin pilot sportys? I loved those tyres had such good feel in them for a tyre for 125's.

Its the OHC engine luckily, but all the kits that are easily accessible for the uk are for the OHV variant, still waiting for new CDI unit, should of been here today, but will probably come tomorrow now.
The 110 michelins fitted without any problems, they grip really well even in the wet, was quite shocked as I've never tried them before.
Ordered a 30mm Carb today as well, should be here for the weekend hopefully. My main question going a bit off topic from the CDI is, when increasing the carb diameter, would the jets need up sizing more than they did before? I know the stock main jet is 100 size, the pilot seems a bit bigger but the guys selling the carb said they couldn't read the size as it was in chinese/japanese which shouldn't be an issue as I'm running a tad lean so hopefully that will correct it. I'm just unsure about the main jet encase I should order some jets in, I got a 95/105/110 laying around for it. I understand the cross section area is 33% bigger than the standard 26mm if that is of any mathematical help,
not surprising as the CB based engine is older than the CG pushrod, I used to run Sava tyres on my Supermoto but they were shocking int eh wet a complete opposite to when it was dry, which region of the UK are you in? If your ever riding round Peterborough or Oxford might catch me on my Honda.
Kennon
I'm not far from dartford in kent, want to do some longer journey's been oxford a few times but that was in my golf gti. Hopefully this summer I'll do my test and get something with around 600cc+
sounds good I didn't want to get anything too overly powerful after my 125 so got a VFR 400R going to have this for a while I think.
Kennon
I've been similar in a way, as I have been on a r6, but they are bloody scary! But I am tempted to get an R6, but I've also been playing with the idea maybe something like a 250cc as a commuter, even a Ninja would be good, it shouldn't be to scary but have adequate power for my commute. Whilst on that subject do the chinese make any sport 250 bikes and are they any good?
You will need bigger jets than what you had before. On my stock carb I had a 110 main jet and now I have 115.
there hasn't been any amazing 250cc sport chinese bikes come out particulary as they are mostly single cylinder and not the best looking things around, the ninja 250 is a good shout but due to allot of people getting them insurance is abit high for what it is my 400 will top out at around 135mph, plenty enough for me for now, the new Ninja 300 is beautiful but procey for sure to get.
Kennon
Was 110 with big bore kit, I will have to dig out my colortune to see how things are looking, I'm guessing a 110 jet should be enough as I imagine the pilot jet will be bigger and compensate for the time being?Quote:

Changed the stock spark plug? Some chinese brand often misfires in high rev.Quote:
