I dunno Tony, but I am at Sea level, the 48/180 with shimmed needle - all done recently on the red - has really boosted the bikes performance - Scott wants me to repeat it on his bike - damn the suffering mileage! - GT - JBOTDS! EZ  | ||

hey EZ....I'm at 86 feet right now and don't get to 200 feet most of the time. Don't you have a Hi-Comp piston in Red? Well Turtle doesn't have the WB on her right now but rather the silenced Jardine so you have more flow than I do and likely more need of fuel. | ||

I tried different needles and different shim sizes and finally switched back to the 175 main jet for the red bike - 180 is too rich on the needle/jet and will bog you till it is on the jet alone on WOT - regular throttle - its fine, but I don't ride like grandma and see no use in something that can't be used in all throttle positions - if I'm missing something -let me know, however, after 3 months of experimenting and now owning 5 different needles - I now stand by 175 as the max for the main, and 45 or 48 for the primary depending on your other mods - GT - JBOTDS!

EZ What needle? Any shims? | ||
| Ezblast |
Your diaphram needle at the top of your carb - my best advice for that is just to shim it as I have written above in the topic explanation space above the posts. I could probably have went with an even smaller needle, however, thats too close to the rich edge of drowning the bike for me - been there and towed that - lol - I'd rather be rich than lean, but not too rich!

Of course all this super tuning was done without a FUELL/AIR Gauage on motorcycle or any DYNO RUNS ... Reminds me of flying the old jennie using a mason jar with 50 weight engine oil in it for an artifical horizon ... | ||

do you always feel the need to stand on that high horse and point out how much smarter you are than everyone else? some of us just prefer to experiment for what feels right on the road rather than what looks perfect on test equipment. | ||
| Ezblast |
This super tuning was done by feel because I could feel the bog - no machine needed - how stupid to think otherwise that a machine would be needed. GT - JBOTDS! EZ | ||

C'mon guys these are fun little bikes not formula 1 cars. A little seat of the pants tuning is fine for this purpose. | ||

True True. If I could afford perfection, I wouldnt be riding a thumper. No offence of course. | ||

and if you go to this page http://www.nightrider.com/biketech/hdcvcarbappendi x.htm it shows a 48 jet with a really different number, so who do i have to blame for posting the wrong number above... and now i have to wait another 4 weeks for harley to get me a 27165-90 48 slow jet is the right number i believe. | ||
| Muckerpuck |
wonder if anyone else has put a stock jet back in there bike cause of that number above.. | ||
| Muckerpuck |
these are what i believe to be the correct numbers.... from here... http://www.nightrider.com/biketech/hdcvcarbappendi x.htm Pilot Jet (Slow Jet) Part Number Jet Size 27165-90.........48........Rich 27170-89.........45........V 27171-89.........42........V 27281-92.........40........V 27117-88.........35........LEAN Main Jet (High Speed) Part Number Jet Size 27105-88..........200........Rich 27185-90..........185........V 27114-88..........180........V 27090-89..........175........V 27115-88..........170........V 27116-88..........165........V 27152-89..........160........V 27154-89..........155........LEAN | ||

Fixed it and added to it! Thank you! GT - JBOTDS! EZ | ||

FWIW I've never bought a jet from Harley. I order from aftermarket suppliers. Its cheaper, faster and you dont have to worry if you've got the right part number. Thanks for taking the time out to post the correct numbers. (that wrong slow jet part number was given by a 'claimed' expert reliable source LOL!) | ||

You should not have to order jets from HD, they should have them in a box, in the parts department, so that the technicians can change them when they put the chrome exhausts on the HD riders bikes. If your HD dealer says that they do not have the jets you are at the wrong dealer, or simply go to a bike supply shop. If there is a HD dealer in your town there is at least 3 HD aftermarket parts suppliers in the area that will have a vast selection of carb jets from which to choose from. Just make sure they are for a CV carb, as the Mikuni jets use different threads and numbering designations. I believe the Drag Specialties carb kits use the Mikuni main jets in them. | ||

i dont go to my local harley witch is an hour away, after they lost my last order after i waited 3 weeks for carb boot... | ||

Muckerpuck, why don't you just order the parts you need from one of our fine sponsers. It is so simple, you tell them what you want, and in three days the part is usually sitting on your door step when you get home. It only makes sense to deal with people who want to sell you the parts. If your local dealer is giving you funny looks, Just Leave. Life is too short, enjoy it. There are better easier options than going to a dealer that doesn't want you there. Good luck! | ||

Amen to that! Story time (and I've told it before): I went to the dealer where I bought my first Blast, after they dropped Buell, and they couldnt tell me enough times that they didnt work on Blasts, wouldnt work on Blasts and wouldnt waste a techs time on a Blast. All I asked was "who owns the custom Blast parked out front"! Needless to say when I bought my next Harley it wasnt from them! | ||

Here Here!   ALL and I do mean ALL dealers around and not so around me, gave me a hard time about my Buell Blast and getting parts. Including one that said he had to charge me overnight shipping just to 3 day a part to me. Even our ex-Buell dealership shunned me when I asked if there are other motorcycle shops around that would work on my bike. It was a real source of contention after I bought my Blast. I found BadWeb and Andy, and I'll never look back. I even hooked up a local garage with Andy, so now I get a really good deal and service from someone who cares! $%&* dealers that give you a hard time. They don't deserve your money! You can bet-ya, when I look to buy my XB I will spend the extra cash to buy out of state. --jim (almost a 12 pack in the wind wielding a keyboard) (Message edited by jimrich on September 21, 2007) | ||

I'm trying the 48/180 combo again with even different shimming - mixed results - will try some shimming a friend suggested - some exact measurements - lol GT - JBOTDS! EZ (Message edited by ezblast on October 11, 2007) | ||

Just ordered some special order stack filters - 10 bucks and change per filter - you'll need a 3 1/2" hose clamp - outerwears.com - the new part number is - "100 - 2651" - the old style didn't flow enough it seems - we'll see - mine will arrive tues - the new prototypes allow twice as much flow while still doing a respectable job filtering. Install the stack like you would the stock venturi using the same specks, torque and new gasket. I sent out filters to some folk to give independent testing who are using the stack intake.

The air filter used on the red bike did produce a noticeable difference in linear power and the red/black bike is now again too damn close to the black bike - there is a difference but its now a lot closer - even airflow is now maximized through the rpm range making the zip much quicker still - can't be too lean though - no popping out the back and the air screw is still the same. There is no lag on the Black bike due to the DAJ keeping things even - but switching to the new filter smoothed things out power wise there as well. Thank you folks for bring it to my attention so that instead of tunning around it, my tunning is now the better for it. Erik and Kyle are giving it a nice try as well - I posted the new filter stock number at the top of the page - you'll have to call or email Outerwears.com to order it and so far it is only in white, but that could change with enough orders - no one believes this but I've always been a form over function kind of guy so the white doesn't bother me and will give me a quicker idea for when I should clean it - lol | ||

FWIW: I tried the stack and 'new' filter and it works, up to about stock rpm limit. Beyond that with or w/o the stack filter, its bad between 6500-7500 rpm. (It runs fine to 7500rpm with the PS air cleaner). I'll wait for the dyno to see what its actually doing between 6500-7500rpm. | ||

Is the stack totally sealed against the carb - I used Permatex hi temp fuel resistant gasket sealer - a lot of folks would use Yama-bond as well - not enough fuel or too much - do you suspect the later is leaving you flat up top? Perhaps the limitations of a fi cam with a carb? - my cam - the B-70 - has the bike taking off at 3500 and hitting 7500 pretty hard though I usually shift around 7100 to 7300 - I hear the XB cam drops off a bit at 6800/6900 rpm and up - at least thats what their dyno's usually show - So whispers the Dark side - Perhaps a nice 580 Redshift - as TP suggests - would be the cam you are looking for performance on a longevity platform - he says after that your into pure racing cams that dramatically shorten engine life - lol - GT - JBOTDS!
