    Dropped the needle a notch ... nice :)

     

    35mm PWK A/S (the airstryker version may be using a slightly smaller pilot & needle clip position)

    42 Pilot

    CEL Needle one clip leaner from middle position

    158 Main

    K&N in the box

    +5 on the plate

    BR8ES

    60* - 900'

    93 Oct

    40:1 SuperTechniplate

    VF-3's

    Inframe CPI's

    Untouched ports - nikasil flashing still on all port openings

    Custom Domes by Titan

    14/41 gearing

    Uncut flywheel

     

     

    Touch on the richer side on just the main jet due to the airbox ... fixing to put the pods back on ... otherwise would have dropped main to 155.

     

    Putting a Dyna on it shortly & will have a set of my curves loaded into it.

    It's not the tranny ... it's the clutch "shuddering" (not the typical "slipping") that you are feeling.

     

    Changing the fluid and/or increasing spring tension typically fixes that "skip" feeling, if not, install new plates.

     

    I have only felt this twice in 10yrs of riding, but I know what that feeling is now & usually only occurs when the clutch conditions are just right ... or wrong rather. Fluid temp/vis & spring tension are the 2 variables that I was able to narrow it doen to when I was experiencing this oddity.

    While we a BS'ing about ignitions & timing, I feel it should be noted that the numbers in my posts are from published sources - One being from Dyna's paperwork that comes with the ignition & the other from the OEM factory service manual.

     

    That being said, it was brought to my attention by a good & reputable source, that if one were to make the fixtures needed & implement a timing light to verify actual ignition firing, that the Dyna has a tendancy to wander a bit & not fire exactly when the end user tells it to. And that through unbiased testing, the MSD has a more stable & accurate corellation between intended & actual ignition discharge.

     

    I have yet to verify this myself, but do believe this to be a good probability... either way, I thought it was good info to pass along. :)

    I knew you would say a turbo, which IMO is a completely different animal. Same with a nitrous bike. My stock curve seems to be doing alright. Like I said, we tried the dyna, it hurt us. I would love to try the programmable pvl one day.

     

    Like I said, show me one of their personal bikes with a dyna. Dome is in two weeks. I'll be sure to keep an eye out for you.

     

    Honest question, why would they have you program one? Because they don't have the cable because they don't run them? The software is free and available online.

     

    With all civility ... I didn't see where you said "personal" bikes ... so in that respect & in the examples I gave, you may very well be right.

     

    The Cougar dyna I programmed for K&T was for a customer bike, I cannot verify weather they do or don't have the cable or software.

     

    Imo - regardless of the type of aspiration, ALL motors will benefit from a custom/spefic ignition lead angle.

     

    The Dyna has it's problems compared to that of the MSD - both in the lack of ability to pull curves from the hardware back to the PC & in the OS required to use it ... that being said if have to reply to this

    they just aren't worth it if you are looking for power. You can do just as well with a timing plate.

    With an opinion of strong disagreement. to each their own I guess. :cheers:

     

    Is the "they" aren't worth it, the Dyna in particular, or just a programmabled ignition all together ?

     

    In seriousness & curiousity, when you gained the 5hp and 550rpm by replacing the Dyna with a stock box - were you using pre-programmed/Dyna loaded curves for the test ? And are you aware that what is loaded as "stock" in the Dyna, is actually far from what is loaded in the OEM ignition ?

    There is more advance/lead angle from 3600 to 10K (nearly 4deg at the upper rpm's) and Dyna flatlines the ignition from 10K on out, where as the OEM unit continues on the same lead angle past 10k. So from 10,001 & up, the "stock" Dyna curve is adding even more timing ... it is nearly +6 at 11K.

     

    If the above wasn't taken into consideration when you swapped to the OEM cdi & reset your plate, it COULD be why the engine reved out the extra RPM giving you the resulting HP increase. If I were to assume you had the "stock" dyna curve selected, with whatever, say 8 on the plate, then I would say the breaking up in that RPM range was due to too much spark lead resulting in some detonation, which limited the extra 550 rpm which left the 5hp you saw on the table ... maybe ? :shrugani:

    LOL - Ok - I'm letting you know - K&T has several Cougars with Dynatek's on them (I programmed I of them per Randy's specs) Dan has one on the turbo Scimitar - A couple of Tim's customers have run them on their DMX build ... & on & on ... :cheers:

     

    After with talking to a few of them it seems as though the MSD may have an edge on the Dyna in a couple of areas, but it all comes back to being FAR superior to a restrictive factory shaped advance curve or a pre-burnt PVL curve. K&T has the Digital PVL software as Tim has the MSD & Dyna Stuff & Dan prefers the disharge capability of the Dyna last I spoke with him (bout a month)

     

    At any rate - it is imo - the same as placing an off the shelf dome on a custom build - every single engine combination wants its own specific timing advance angle to coincide with how the engine builds volumetric effiency. The ever popular "throw +8 on the plate" with a stock box way of thinking may get the job done in some aspects, but is far from being optimised. The Dyna, in particular, but not limited to, will rev clean past 11K & in a few applications I have had no problem in excess of 12K

     

    Just some FYI

  21. Serval dome selection

    imo - i would be VERY hesitant to say "put this CC dome on" as there are no less than a dozen variables that need to be taken into account concerning dome profile construction ... that's the main reason why I gave all the info I could gather about the Serval I put together except "that" aspect ... it is just way to dynamic & specific to each engine & dome designer to generalize. The combustion chamber imo - is the place in the engine where all the magic happens & should be given way more respect than "what CC dome do I use" ... I hope that comes across without an undermining tone, but rather as just trying to be helpful for all the different levels of readers on this forum. :)

    i would also love to put them to the test on the wild alaskan "course", lol......i think he is too far past r&d hand-outs/trials....and i have the full low-mid setup, too....lectron 30's w/pj's, boysens, dyna fs programmable, dd lock-up, billet basket, 22/12/9 mud tires, ptr powerhead, pcp's, etc, etc...enough to handle the abuse, and even spare pipes/reeds, etc to change things up a bit....i'm just on the fence about shelling out for the cyls, or continue with what i was buiding up already....

     

    Don't know of anyone that got a r&d handout/trial ... pony up the money, you'll dig it, with or without the "full low-mid" set-up ... ( :yank: ) :D
