lineaweaver dell orto

having many failings i feel i have big enough shoulders for simon to point them out now and again because in balance of these i have my 'up 'n at 'em' attitude that gets things done.

one thing that has sat there makng me think "poor children!" has been the this thread long acknowledged in the doc as how to get a dell orto working:

http://www.husaberg.org/index.php?name= ... ic&p=13863

it has been essentially a spilling of the lineaweaver beans. a gem of information, a nugget to be treasured! i trust done with "il cognicenti's" permission! amazed, yep! amazed that this gem of info has not been used by anyone i can recall, or whom mentioned it. NOT!!!!!!!!!! (or to acknowledge the time consuming hard work it took).

i stand to be corrected and await a tyraid of "i did it and said so....!!!"

but, i did "it" today and phuqing hell! what a rocket! the FE650e, previously juddering and banging had had the ignition advanced 10 degrees and then, yep! BIT THE DELL ORTO BULLET!!!! .....to driiiiiiilllllllll with no going back!

so, i drilled the PA and the MA, blew it out, changed the 'fat' 42 for a svelte like 33, the K51 on C2 was good to go as was the 45 choke and the 190 main (heimar's considered opinion for a 650), the slide was filed from what was actually 3.75 to 4.25mm as i figured the important bit was the ".5mm" and then screwed it all together!

it started first kick. i stopped it for fitting the strobe and fuel tank, then. first kick. i then togged up to ride and guess what? ... first kick! i pulled over and stopped then ........first kick!

the engine that had popped and banged was SILK smooth just like the FCR. no glitches, coughs or splutters! i could not fault it.

joe was on the money
lineaweaver was on the money
simon was kinda on the money
(nice stator mr sparks)

where were you? :?: :?: :?:

As Joe put it, 'Intake Reversion' is the issue. So why then couldn't an intake reed valve be fitted as on a two stroke to alleviate the problem?

hi eric

well i guess it's because only a small percentage that is reversed and that unlike a two stroke which would all come back out if it could instead of going up via the transfers? that's hardly the problem here though is it?

i believe that early XR 500's had a reed didn't they?

but i think something is missing here. the engine i'm working on has a LX1 cam grind and needed this work. as joe says he's not 100% sure that the standard cam would need this. to me though the fuel curve on husabergs barely changes and therefore i see this as something that would work with a 53 or 55 cam etc.

remember that froggy had dale "breath" on his and i would trust that the very same work was done. i have no doubt that a standard bike would benefit. i ran 33/35 PJs in my little 400 so feel i could have done with something akin to this mod.

thing is - nobody has tried ......

Sure did.

I think you would be struggling to find any bikes out there with them still fitted though.

i would have thought that the MA drilling would work even with the standard cam?

I'm so sorry Taffy, I've been neglecting you lately, as I've been neglecting this community

I'd have to believe we've both got shoulders wide enough to handle some healthy banter between us now and again.....

In the meantime, I've got to accept "kinda right" as just a bit of a compliment :wink:

All the best,
Simon

RE: Re: lineaweaver dell orto

"kinda on the money" you dislexic you!

you did say the dell orto could be tuned the same as a keihin. i was told eithere here or in a PM once by DL that he puts keihin kit in the dell ortos. i was so pleased with the results that i wish i'd started down this road and had a go at it.

if you (all) didn't know, the dell oroto needles are a ******* to graph - the keihins make them look stupid. but to have got hold of the K35 and the K51, graphed them and taken everyone to keihin needles would have been fun!
