The only thing i can recomend and know is worth money is the dynojet kit! Last one here on forum confirmed it made nice improvement, sounds to me like you need to get more fuel Jens.

Sorry your results are so disappointing, I tried lots of mods but nothing changed much until I got a lot more air and mid range fuel to the motor. Try it with the top/side of the airbox off , and raise the needles just as a experiment. That advance at idle and just after needs fuel to burn. My throttle response down low improved also. THUMPTHUMP

I have 2 new units I'm testing(on 4 XT's), plus all the old and found unless the stock cdi is crappy you won't find much, if any, performance increase. Easier starting has been the one common thing I've seen with both new units over the stockers.
Air and fuel is what these motors need, badly.

So im throwing in the towel....Cant make this cdi with the '86 map work properly.

I've tried as fat as 130/130 jetting, with both needles completely raised, and a 48 idle jet. I run without the snorkel in the airbox, KN-filter and have even removed the whole side of the airbox, played with removing db-killer ect ect... You name it, I've tried, for a whole day with different settings.

I just about got the pinging away, but the engine still acts "rough", and no HP gains. The stock cdi is sooo much smoother.

So for me atleast, a complete waste of a lot of money, and a lot of my spare time.


Soeh, anyone wanna buy a new cdi...?

Where is it pinging ? low rpms? high? I wonder if you need the older carbs they are bigger cfm I believe so will allow more mixture in. If you were in the US I'd borrow you a set to try. Otherwise pm me with how much you'd want for the cdi , I have a 3tb and will be using an older set of carbs, if not my efi system I'm working on (oops, shhhhh).

In the US regular gas is 86 octane, plus is 89 octane and premium is 91 or 93 depending on where you live. You probably have different terms for grades of gas. 86 is the most likely to ping and 93 is the most likely not to ping, or knock as we call it. predetonation. thumpthump

Yes here we run on 95octane and same for Jens. Strange you have so low octane, is it same on cars? we can also get 98/99octane. How are the old bikes/cars handling the difference from 86-93 without any change in the ignition?

Ok i see: Research Octane Number (RON) is used, but in North America, the Anti-Knock Index (AKI) is used. Conventional 'standard' "Premium Unleaded" petrol in the United Kingdom, Europe, South Asia and Australia has an octane rating of 95 RON, and in North America it is AKI/RdON/PON 91-93 (RON 96–98).

Our "regular' is 87, not 86 , the 89( both with ethanol), and 91(non ethanol), Then race gas!!

Out west I've seen 85 as regular and 93 premium,so it's are dependent on what is run. I believe they use a little different method of classifying gas in Europe than here in the US.
