stall resistance
figured id post the reasons why i love the 250 digital ignition here too...
so heres how low she can go, keep in mind i am running a nice and light flywheel, really this is better than a xr200, i doubt theres anything to be gained by adding weight
another one, that noise at 1:33 is the engine stalling, then roll starting itself just like the OE 500 stuff

heres me on a trail riding how i would normally, 4th gear the whole way, no clutch slipping, just pulling it in for the corners and dumping it with some gas on the exit, if you want smooth power stop wasting your time on a FWW, this is as smooth as it gets boys and girls (as far as power delivery, not riding style )
riding like this keeps the gyros to a minimum for a skinny guy like me
got a 952 with no side knobs on the front, and a fried 140 M5B on the rear

heres the same deal but in 5th, its too high a gear but its to show how the motor will behave with a proper ignition, if that isnt smooth enough for you then youre beyond help
decide for yourself, but i say its more tractable than my trials bike, yet extremely responsive

the 450 will have less power and will be harder to start, and will be heavier, but to make up for it it will require more maintenance.

true its not stock, but if i swap back to the 500 stuff (and i have more than once) i cant lug down even close to the same, it does seem a bit better than other 500s i have rode, but those 500s were not jetted properly, who knows what pulsar gap, reeds......The motor isn't stock, just a ignition isn't the whole story
some other stuff may help it from stalling, but it will be a small fraction of what the 99 250 ignition does

when i had a lighting coil (electrosport L99) i had other electrical issues so not 100% sure what was what, but i dont think it would lug down quite as low as those vids, but it was still light years better than stock
stock the stator has 8 poles, on a lighting coil 5 of those poles power your light leaving only 3 to power the spark
i will be putting it back on as soon as it heats up to run a fan and i will get some more vids and compare them to see for sure if it affects it

I posted this a year or so ago here as well, I don't know of anyone else that has done it.
I have a couple new stators that have 40 watts they put out. Not sure what they would do if they were rewound.

Yes, I read that with great interest Sean. Only thing that put me off a bit was the additional flywheel weight, which I think actually hurts a 500 as much as it helps a 250 . . . . also, I run everything through a standard CRF450X battery to retain indicators, parklights, and all the other crap for road legality, so I only need about 25 watts at most to keep it charged for normal use. OK, If I rode all night, and had the headlight on full time, it would gradually flatten the battery as the charge rate failed to keep up with consumption, but I cant see that situation arising, frankly.seanmx57 wrote:http://www.thumpertalk.com/topic/871239 ... d-to-read/

i usualy run 14/49, but its 13/49 in that vid, but i think that is irrelevant the sprockets have nothing to do with how well the engine runsHey twostroke, what is your gearing? thanks

I heard how well it runs down low. just wanted to know your gearing. it was your 5th gear video that got me wondering.2strokeforever wrote:i usualy run 14/49, but its 13/49 in that vid, but i think that is irrelevant the sprockets have nothing to do with how well the engine runsHey twostroke, what is your gearing? thanks
