Oh oh!!!im excited!!!Tomorrow I will have the answer why oh why there so many ktm300 electric start issues!!!Im 99% sure I know the answer but Im not saying anything yet!!!Anyway got some good info so far it's 12am after a 40degree day I been busting my balls but here's a 10k run up on a DC CDI system

Maybe KTM will give you a new bike if you share that info with them

little bit questioning to my kawasaki and ind same person ktm-dealer...  the e-start-system on the earlier ktm 300 is a helping tool for sections with died engine and to less space to use the kickstarter... the earlier systems are not strong enough for coldstart...  the last 300 2stroke enduro they sold was my buddies bike 4 years ago... 
was hoping to find some info, that could help... 

what says the dynotest ??

Ok I'll spill it....what I see is the ktm requires 670 rpm to start producing spark....With all the mechanical design faults I found,the original system must be tittering over the edge of working and not working out of the box...SO,it's looking like its a firmware problem!!!As big as these companies are believe it or not sometimes there are miscommunication between the contracting companies and the main manufacture...and sometimes there's just things that have been forgotten about or simply not even thought of....I reckon there is a perimeter for functionability that's a f up in the CDI...today I will prove it is infact the CDI box itself or the trigger pick up by placing a second pick up tab on the flywheel ...what this will do is trick the cdi into thinking its doing double the RPM it really is...the sensor itself is happy to see and relay what it sees on the flywheel

On another note if anyone wants some of these I got plenty...50 sets...it was the only way I could get them done was in volume...I got shafted on the cost

[sandblaster]

How much a set including shipping to the US?

[ylwgtr]

let me count how many i got and will divide my arse raping into it and we can all share the love

[ylwgtr]

Righto boys exceptional news....it cranks and starts off the starter motor like a ripper!!!!All I've heard along the way is "this won't work that won't work blah blah blah" All this is a drive for me....Think of something you want to do boys and chase down the answers and make it happen 

[sandblaster]

That's great news.
What was the issue and the fix?

[ylwgtr]

I no longer have a ktm CDI  to test...I will have to wait for it to come back before I can say for sure but I'm confident in saying its a firmware error....it locks out spark below a specific rpm..one which is far to low for my kx to fire and I'm guessing on the edge of the ktm's mechanicals rotation once the bendix gets dry,battery is run down or starter a bit worn(2 hours after it was new ) I've switched to a mappable DC CDI for the moment...may look at reverting back to an Ac one once I get it 100% back together and tuned..but for the moment I'm happy to have conquered this project,it's been a bit of thinking but I got a result...

[motopunk]

real good news...  you caught the devil that has stolen the sparks...

That is absolutely the coolest bike on the planet Earth right now. Check this out Kawasaki,,,, wasting R&D on crap when the best off-road motor sits on the shelf.

[motopunk]

you got it running with the e-start... awesome to see that it works now..
