You have already shown yourself to be more superior at this sort of thing than most so my 2cents is probably not worth much. but it sounds like a cranking speed issue to me I have had quite a few differant atvs that when the battery is old ore the starter worn that will sound like they are cranking fast but wont start intill either pulled or kicked or hooked to a charger .
When are you going to start selling those adapter plates??

hi toby any input is appreciated mate :-) I aggree with you there on the cranking rpm...but i tell you i reckon im close to makimng enough power....everyone thats herd it crank over has commented that they have never heard a KTM300 crank over that fast....i need to get my hands on a KTM and check the cranking power thats generated from the CDI charge coil....also how many puffs i get out the pipe per 10 secs of cranking and and work out the cranking rpm's and compare to mine

Another cool way to measure RPM's is to get a frequency measuring App for your smart phone (if you have one) and hold it by the exhaust outlet while cranking. They make some guitar tuning Apps too that may work great for this!

yes thats exactly my thought... its worth a try, to see if the spark comes back by e-start. i saw your video and the 300īs turns also with this crank speed. by kicking over is the crank on the most bikes slower as by e-start...
crank speed measuring is also a great idea for direct comparing between ktm 300 and kx500 . also a stronger battery could bring better e start performance.
you do a real great work . the first one who make this to reality and i think you are very very close to the finish line of this project... 8-)

thanks bloke :-) im going to pick up a ktm300 tonight so i can do some tests with it over the weekend :-)
